    TITLE: Scientists discover mysterious “lonely” brain waves linked to memory loss

    URL: sciencedaily.com/releases/2026

    Scientists have uncovered a surprising link between Alzheimer’s-related protein buildup, disrupted brain waves during deep sleep, and fading memory. The findings suggest that hidden changes in how the brain processes memories overnight may contribute to age-related memory loss long before Alzheimer’s symptoms appear.

    TITLE: Voters value long-term economic growth more than previously thought, study finds

    URL: psypost.org/voters-care-more-a

    People evaluating politicians often seem to care only about recent economic events, but new research shows voters actually just prefer a steady upward trajectory. The study, published in the American Political Science Review, indicates that individuals are willing to endure poor initial conditions as long as they see things getting consistently better.

    Political analysts frequently describe the electorate as shortsighted. When deciding whether to reelect an incumbent, voters rely heavily on the state of the economy in the year leading up to the election. They tend to ignore the conditions from earlier in a politician’s term, a pattern that has led many researchers to label voters as myopic.

    This concept fits into different theories of how democracies function. In a sanctioning model, elections act as a performance review. Voters look at past conditions and punish or reward the politician in charge. In this view, a narrow focus on the recent past is a flaw, allowing politicians to coast for years and only boost the economy right before an election.

    Another theory approaches elections differently. In a selection model, voters act like hiring managers trying to figure out which candidate will deliver the best results in the future. Here, past performance is just a clue to gauge a candidate’s overall competence. A rising economic trend might signal that a politician knows how to build sustained success.

    Researchers Markus Prior of Princeton University and Talbot M. Andrews of Cornell University designed a series of surveys to test these conflicting ideas. They wanted to know if people have a universal blind spot for long-term data or if they simply value the concept of improvement.

    In their first two surveys, the researchers asked participants to evaluate four-year sequences of aggregate data presented as bar charts. Some participants viewed historical data, while others viewed projections of the future. The data represented economic growth in one survey and environmental conditions, like air quality, in the second.

    The results replicated earlier findings regarding the past. When looking backward, participants placed the most importance on the final, most recent year of data. But when evaluating projections of the future, people did not focus on the immediate short term.

    Instead, participants evaluating the future cared most about the most distant projected year. Rather than being shortsighted, they were farsighted, a pattern known as hyperopia. Across both past and future scenarios, participants gave the highest ratings to data that steadily improved over time.

    This preference for upward momentum led the researchers to design a choice-based experiment. In two additional surveys, they used an adaptive measurement technique to calculate exactly how much people value an improving trend. One of these surveys featured a large sample of more than 2,000 respondents.

    Participants viewed a single chart displaying two different paths over a four-year span. One path showed a flat, consistent rate of either economic growth or job creation. The other path showed a steady upward climb. Participants had to choose which scenario they preferred.

    Depending on the participant’s choice, the researchers adjusted the flat path on the next screen. If a participant chose the rising trend, the researchers made the flat trend slightly higher and asked them to choose again. By repeating this process, the researchers found the exact breaking point where a participant became indifferent between the two options.

    The results showed that people routinely chose the rising trend even when the flat trend delivered a greater total benefit. Participants were willing to sacrifice overall economic welfare just to experience an upward trajectory.

    On average, a person required a consistent flat income growth rate of at least 2.3 percent to pass up an improving trend that averaged only 1.3 percent. When looking at temporary job creation, participants preferred an improving market that created an average of 243,750 jobs per year over a steady market, unless that steady market guaranteed at least 350,000 jobs annually. Between about a third and nearly half of the participants in the large survey (32 to 46 percent, depending on the domain and time orientation) exhibited a preference for improvement so strong that they chose rising sequences that were mathematically inferior in every way to the flat alternatives.

    The researchers then explored whether this behavior was driven by genuine preference or a visual illusion. People often rely on mental shortcuts when reading graphs. One common shortcut is to judge an entire sequence of events solely by how it ends, ignoring the data points in the middle.

    To discourage this reliance on visual shortcuts, the researchers introduced modified graphs to a portion of the participants. These modified charts explicitly displayed the total cumulative numerical benefit on the screen. The researchers also grayed out the blank spaces on either side of the data to stop participants from mentally extending the upward slope into the future.

    These visual tweaks reduced the preference for improvement. The adjusted graphs helped participants recognize the higher total value of the flat trends. However, the preference for improvement did not disappear entirely. The modified charts showed that a substantial portion of the population still genuinely values an upward path over a flat baseline.

    The study relied on clean, steadily climbing graphs in a controlled setting. Real-world aggregate conditions often feature jagged, inconsistent data that might alter how individuals perceive national progress. It is entirely possible that voters react differently to unpredictable economic bumps than they do to smooth survey charts.

    Future research could investigate whether voters actually credit incumbent politicians for long-term improvements when they cast their ballots. Political campaigns frequently use customized graphs to highlight their own successes or criticize opponents. Studying how individuals encounter and interpret these trends in actual media reports could reveal how campaigns manipulate perceptions of progress.

    The findings suggest that the human desire for progress fundamentally shapes how we view national success. The study, “Are Voters Myopic or Looking for Improvement?,” was authored by Markus Prior and Talbot M. Andrews.

    TITLE: Social anxiety might not warp how we perceive eye contact

    URL: psypost.org/social-anxiety-mig

    A recent study challenges the idea that people with social anxiety consistently perceive others as staring at them more than those without the condition. Published in Journal of Affective Disorders, the research reviewed past claims and conducted new experiments, finding that previous links between social anxiety and altered gaze perception are weak and difficult to replicate. The findings suggest researchers should reconsider using this perceptual trait as a standard biological marker for social anxiety.

    In everyday social situations, humans must constantly judge where others are directing their attention. To measure how people process this information, psychologists evaluate what they call the cone of gaze. This concept refers to the specific range of angles at which a person feels that another individual is looking directly at them.

    Imagine sitting on a train across from a stranger. Even if the stranger is looking slightly over your shoulder, you might still feel they are making eye contact. The width of this imaginary cone dictates how far a person’s eyes can deviate from the center before you decide they are looking away.

    For years, some psychologists have proposed that the cone of gaze could serve as a biological and behavioral marker for social anxiety disorder. People experiencing high levels of social anxiety often report feeling heavily observed or judged by others. Based on this clinical observation, earlier research suggested that socially anxious individuals possess a wider cone of gaze, meaning they interpret a broader range of angles as self-directed eye contact.

    To explain why scientists think the cone of gaze might change, it helps to look at how the brain processes visual information. Psychologists generally divide this into two streams. Bottom-up processing involves the raw visual data the eyes take in, such as the exact position of another person’s pupils. Top-down processing involves a person’s internal expectations and beliefs.

    When visual data is ambiguous, the brain relies more heavily on its top-down expectations. Because humans have a strong default assumption that others are looking at them, poor visual evidence usually causes people to assume they are making eye contact. Psychologists suspected that people with social anxiety might naturally avoid looking directly at other people’s eyes. By looking away, they gather less bottom-up visual evidence, forcing their brains to rely on top-down expectations and hypothetically widening their cone of gaze.

    Other studies proposed that angry facial expressions also widen this cone for the general population. This idea is based on the evolutionary benefit of detecting a potential threat. If someone looks angry, it pays to assume their anger is directed at you.

    To test the reliability of these concepts, a team led by Madeleine E. Moses-Payne at University College London evaluated the existing scientific literature. The research team, which included Georgina Krebs, Raphaëlle Delpech, Antonina H. Przyborowska, and Argyris Stringaris, wanted to determine if the differences in gaze perception were consistent enough to act as a diagnostic tool. They designed a two-part investigation featuring a synthesis of past research followed by fresh experimental trials.

    The investigators first conducted a meta-analysis, which is a statistical technique that combines data from multiple independent studies to identify overall trends. They pooled data from ten previous studies that compared the cone of gaze in socially anxious individuals against those without social anxiety. This combined group represented a total of 403 participants.

    The pooled results showed a modest association, suggesting that socially anxious people did have a wider cone of gaze. However, the researchers noted that the existing evidence was highly inconsistent. The individual studies were often quite small, and mathematical projections indicated that future studies could just as easily produce contradictory results.

    A second meta-analysis examined how emotional expressions alter gaze perception. The team combined nine past studies representing 523 participants. These studies compared how people judge the gaze of angry faces versus neutral faces.

    The analysis revealed a slight trend where participants perceived angry faces as looking at them over a wider range of angles than neutral faces. Much like the first analysis, the data showed extreme variation between the studies. The high degree of inconsistency led the researchers to question the reliability of the previously reported effects.

    Because the historical data proved unreliable, Moses-Payne and her colleagues recruited 514 participants for three new online experiments. Participants viewed images of faces presented on their screens for a fraction of a second. The faces featured eyes angled at various degrees, ranging from looking straight ahead to looking eight degrees to the side.

    For each image, the participant had to press a key indicating whether the face was making eye contact. All participants also completed a standardized questionnaire measuring their current symptoms of social anxiety.

    In the first experiment, 193 participants evaluated faces showing strictly neutral expressions. The researchers then mapped each participant’s responses against their social anxiety scores. They wanted to see if higher anxiety correlated with a wider cone of gaze.

    The results were not statistically significant. Participants with high levels of social anxiety performed almost exactly like those with low anxiety. Both groups judged faces to be making eye contact at roughly the same angles.

    The second experiment tasked 172 new participants with the same exercise, but all the faces displayed angry expressions. The goal was to see if the presence of a social threat would trigger a widened cone of gaze. The researchers were particularly interested to see if this happened for those with elevated anxiety.

    In this specific setup, the researchers did observe a slight effect. As social anxiety scores increased, participants demonstrated a fractionally wider cone of gaze. For every one-point increase on the anxiety scale, the cone widened by just 0.01 degrees.

    The third experiment presented 149 participants with a mix of both angry and neutral faces. This design allowed the researchers to compare the effect of emotion within the same testing session.

    Once again, the results were not statistically significant. The presence of social anxiety did not widen the cone of gaze. Additionally, the angry expressions did not alter participants’ perceptions compared to neutral expressions. Even when the researchers isolated just the angry faces in this third trial, the link to social anxiety vanished.

    When the research team combined the data from all three new experiments, they found no overall relationship between social anxiety and the cone of gaze. The collective data also showed that angry expressions did not widen the range of perceived eye contact. The single positive finding from the second experiment failed to hold up when viewed as part of the broader data set.

    The researchers highlighted several limitations in their work. The participants in the new experiments were evaluated using a validated symptom questionnaire, but they were not formally diagnosed with social anxiety disorder by a clinician. A sample of patients with formal clinical diagnoses might yield different patterns of gaze perception.

    The experimental trials were conducted entirely online. In-person testing environments sometimes introduce what psychologists call a social evaluative threat, where the physical presence of a researcher induces self-focused anxiety. The lack of an observing researcher in the online setup might have reduced the participants’ baseline anxiety, potentially dampening any effects on their visual perception.

    Future studies could explore whether explicitly introducing social pressure alters how people perceive eye contact. Researchers might achieve this by asking participants to prepare a public speech before the visual task.

    Scientists could also use eye-tracking technology to determine if socially anxious people avoid looking at eyes entirely. This avoidance would limit the visual information they absorb. That visual deficit would force them to rely on their baseline assumptions about being watched, which could help explain the variations seen in previous research.

    The study, “Is everyone looking at me? The perception of direct gaze as a potential cognitive marker in social anxiety and its moderation by emotional expression,” was authored by Madeleine E. Moses-Payne, Georgina Krebs, Raphaëlle Delpech, Antonina H. Przyborowska, and Argyris Stringaris.

    TITLE: In female mice modeling schizophrenia, a single dose of psilocybin restored sensory filtering for days

    URL: psypost.org/in-female-mice-mod

    A single dose of psilocybin triggers heightened immediate behavioral reactions in mice bred to model aspects of schizophrenia, yet also produces a lasting improvement in sensory filtering among females. The findings suggest that the immediate psychedelic-like effects of the compound and its longer-term influence on brain function may operate through distinct biological pathways that vary by sex. The research was published in Neuropsychopharmacology.

    Psilocybin is the primary psychoactive compound found in so-called magic mushrooms. Once consumed, the body converts it into psilocin, a molecule that alters perception, mood, and thought primarily by activating serotonin 2A receptors on the surface of brain cells. Although psilocybin is being widely tested in clinical trials for depression and anxiety, its effects in schizophrenia, a severe psychiatric disorder marked by hallucinations, delusions, social withdrawal, and trouble filtering sensory information, remain poorly understood.

    Because psilocybin can temporarily mimic psychosis-like changes in perception and brain network connectivity in healthy people, modern clinical trials routinely exclude anyone with a personal or family history of psychotic disorders. According to a 2024 systematic review and meta-analysis of human studies, psychedelic-induced psychosis is rare: about 0.002 percent in population studies, 0.2 percent in uncontrolled trials, and 0.6 percent in randomized controlled trials.

    The same analysis estimated a 3.8 percent rate of long-lasting psychotic symptoms among patients with schizophrenia, but that figure came from two small, uncontrolled LSD studies conducted more than fifty years ago and judged to have a high risk of bias, leaving open the question of how brains vulnerable to psychosis respond to psychedelics.

    Understanding that vulnerability requires looking beyond serotonin to glutamate, the brain’s primary excitatory chemical messenger. Evidence from a 2008 study on brain receptor complexes indicated that serotonin 2A receptors can physically pair with a type of glutamate receptor on cortical neurons, shaping how the brain responds to hallucinogens. The new study focuses on a different member of the same receptor family, metabotropic glutamate receptor 5, which sits on nerve cells and helps regulate learning, emotional control, and the strength of connections between neurons.

    Mice genetically engineered to lack this specific glutamate receptor display several traits relevant to human schizophrenia, including hyperactivity and impaired sensory filtering, which can be eased by standard antipsychotic medications. In a 2010 experiment in mice, animals missing this glutamate receptor showed exaggerated bursts of physical activity when given a synthetic hallucinogen that stimulates serotonin 2A receptors. At the same time, psilocybin has been shown in mice to promote the growth of new connections between brain cells, raising the possibility that it might ease certain schizophrenia-related deficits after its acute effects wear off.

    Biological sex also shapes how animals react to psychedelics. For instance, an earlier experiment comparing male and female rats found that adult females displayed more psilocybin-induced head twitches than males, with responses fluctuating alongside estrogen levels. To explore how disrupted glutamate signaling and biological sex interact during and after psychedelic exposure, lead author James J. Gattuso, a PhD candidate at the University of Melbourne based at the Florey Institute of Neuroscience and Mental Health in Melbourne, Australia, conducted the new study alongside senior authors Anthony J. Hannan and Thibault Renoir.

    “Psilocybin’s effects on biology relevant to schizophrenia remain poorly understood, partly because people with schizophrenia have generally been excluded from modern psychedelic trials over concerns about worsening psychosis,” Gattuso told PsyPost. “At the same time, there is growing scientific interest in whether some of its longer-lasting effects might have therapeutic potential for particular aspects of the disorder. We wanted to investigate both the immediate responses and the longer-lasting effects of psilocybin in a mouse model that captures some features relevant to schizophrenia.”

    The researchers worked with four-month-old male and female mice divided into two experimental cohorts, one for behavioral testing and another for brain tissue analysis. Each cohort included both mice genetically modified from conception to lack the metabotropic glutamate receptor 5 and a comparison group of genetically typical littermates.

    The behavioral cohort consisted of 96 mice, with 10 to 14 animals per subgroup, that underwent a series of tests before and after receiving an abdominal injection of either 1 milligram per kilogram of psilocybin or an inactive saline solution. To prevent pre-existing differences in baseline nervousness from skewing the results, the authors balanced the treatment groups using exploration scores recorded one week prior and alternated testing across morning and afternoon hours.

    Immediately after the injection, the mice were placed in an activity chamber for 30 minutes to track the total distance they moved. During the first 15 minutes in the chamber, overhead cameras recorded the animals so a researcher blinded to their group assignments could count their head-twitch responses, rapid side-to-side head movements that serve as a standard rodent indicator of hallucinogen-driven serotonin 2A receptor activation. Two weeks later, a subset of 47 mice received a second injection of psilocybin or saline to test whether repeated exposure altered their immediate reactions.

    Because the active breakdown product of psilocybin clears from mouse blood in about four hours, the team scheduled follow-up tests over the next nine days to measure lingering effects after the drug had left the body. On days one and nine after the injection, the mice completed a prepulse inhibition test, which measures sensorimotor gating, the brain’s ability to filter out redundant sensory stimuli so it is not overloaded. In this assay, a quiet warning tone is played 30 or 100 milliseconds before a loud, startling noise; a healthy brain uses the quiet tone to dampen the physical flinch to the loud sound, whereas people with schizophrenia and mice lacking the glutamate receptor typically show less of this dampening.

    On days three and seven, the mice were evaluated for anxiety-like and depressive-like behaviors. For the light-dark box test, animals spent 10 minutes in an arena split into a dark compartment and a brightly lit chamber; spending less time in the bright area reflects heightened anxiety-like avoidance. Thirty minutes later, the mice underwent the Porsolt swim test, commonly known as the forced swim test, in which they were placed in a beaker of water for six minutes while automated software tracked how much time they spent floating immobile during the final four minutes.

    The second cohort of 61 behaviorally naive mice, with 5 to 10 animals per subgroup, was used to examine brain activity. These mice received the same psilocybin or saline injections and had their brains collected 90 minutes later to measure levels of c-Fos, a protein that marks recently active neurons, across four brain areas involved in psychedelic action and movement.

    During the first 30 minutes after dosing, psilocybin triggered a sharp increase in physical movement among mice lacking the glutamate receptor, whereas the change in distance traveled among genetically typical mice was not statistically significant. Mice missing the receptor were also more active than typical mice overall regardless of treatment, and glutamate-deficient males moved more than glutamate-deficient females.

    In the 15-minute video recordings, psilocybin increased head twitches across all groups compared to saline, peaking between five and 10 minutes after the injection. Male mice lacking the glutamate receptor exhibited a much larger surge in psilocybin-induced head twitches than genetically typical males, while the difference between the two female groups was not statistically significant.

    The authors caution against reading this as a sex difference, however. Typical females already showed more head twitches than typical males, narrowing the gap between the two female groups, and knockout males and knockout females did not differ from each other, a pattern the authors interpret as a broadly heightened sensitivity in mice lacking the receptor.

    “This behavior is an indicator of psychedelic-related serotonin-receptor activity in mice, but it is not a direct measure of hallucinations, psychosis, or harm,” Gattuso explained. “It points to altered sensitivity that warrants further investigation, and we hope our findings encourage continued attention to how sex and underlying biology shape responses to psychedelics.”

    When the subset of 47 mice received a second dose two weeks later, with males and females analyzed together, psilocybin again increased movement and head twitches, though the larger head-twitch response in mice lacking the glutamate receptor emerged at the second dose only after one outlier was removed. Overall, the differences between the first and second injections were not statistically significant, suggesting no lasting tolerance or sensitization under these conditions.

    In the brain tissue analysis conducted 90 minutes after dosing in small groups of 5 to 10 mice, the researchers focused first on the claustrum, a thin sheet of neurons tucked beneath the inner surface of the neocortex that is thought to act like a switchboard coordinating activity across distant brain networks. Psilocybin increased the density of active, c-Fos-positive neurons in the claustrum of genetically typical mice compared to saline, whereas the difference between psilocybin and saline in mice lacking the glutamate receptor was not statistically significant.

    The authors suggest that intact signaling through this glutamate receptor contributes to psilocybin’s recruitment of the claustrum, and they propose, as a speculative idea that still needs to be tested, that weaker engagement of this coordinating hub could contribute to the exaggerated acute reactions seen in the receptor-deficient mice.

    In the dorsomedial striatum, a deep brain region involved in goal-directed movement, mice lacking the glutamate receptor showed lower overall neuronal activity than typical mice, while the effect of psilocybin was not statistically significant. Effects of psilocybin in the dorsolateral striatum, prelimbic cortex, and infralimbic cortex were also not statistically significant, though male mice displayed higher overall neuronal activity than females across most of the examined regions.

    In the post-acute tests on days three and seven, mice lacking the glutamate receptor spent less time exploring the brightly lit compartment of the light-dark box than typical mice, consistent with their baseline anxiety-like trait. However, the effect of psilocybin on time spent in the light, distance moved, or transitions between chambers was not statistically significant. In the Porsolt swim test, psilocybin-treated mice across both genotypes and sexes spent more time floating immobile than saline-treated mice.

    Although increased floating is traditionally interpreted as a depressive-like passive reaction to stress, the authors propose an alternative explanation: because all mice had experienced a baseline swim session five days before receiving the drug, the extra floating may reflect adaptive learning and energy conservation in an inescapable situation. Among psilocybin-treated females on day seven, individual mice that had displayed more head twitches right after injection actually spent less time floating, whereas correlations on day three in females and on both days in males were not statistically significant.

    The overall group increase in immobility stands in tension with an earlier study of depressive-like behavior in rats, which found that a single dose of psilocybin reduced swim-test immobility for up to 12 weeks alongside lasting increases in neuronal excitability in the medial prefrontal cortex. However, that earlier work examined long-term outcomes weeks later in a rat model of depression rather than post-acute responses in a mouse model of schizophrenia.

    The most notable long-term change emerged in the sensorimotor gating tests on days one and nine. At the 100-millisecond warning interval, psilocybin improved prepulse inhibition across female mice compared to saline, whereas the effect in males was not statistically significant.

    At the shorter 30-millisecond interval, saline-treated females lacking the glutamate receptor showed impaired sensory filtering compared to saline-treated typical females, and a single dose of psilocybin restored their filtering performance to a level where the difference from typical females was no longer statistically significant. This benefit persisted through day nine and held up after the researchers statistically accounted for differences in startle strength between the genotypes. In males, by contrast, saline-treated mice lacking the receptor did not show a statistically significant deficit at the 30-millisecond interval, and psilocybin’s effect was not statistically significant.

    “That persistence and normalization to the control mice is an exciting feature of the findings,” Gattuso said. He described the main takeaway as “a promising lead for further research into psilocybin’s therapeutic potential, although improving one measure in mice does not establish that it will treat schizophrenia in people.”

    “The sex differences were particularly striking: we observed a lasting improvement in sensorimotor gating in females, but not males,” he noted. “Finding this potentially beneficial effect was especially interesting given the concerns surrounding psychedelics and schizophrenia.”

    When the team compared acute head twitches to day-nine sensory filtering in psilocybin-treated females, they found a negative correlation: females that had shown more head twitches immediately after dosing tended to have lower prepulse inhibition nine days later. Correlations on day one in females and on both days in males were not statistically significant. In the authors’ reading, this pattern supports the possibility that the immediate hallucinogen-like reaction and the lasting change in sensory filtering arise through separate mechanisms.

    There are a few things to keep in mind when interpreting these results. First, the experiments were conducted in mice missing the metabotropic glutamate receptor 5 from conception, which models certain biological features of schizophrenia but does not capture the full complexity of the human disorder. Because the receptor was absent throughout brain development, some of the altered responses to psilocybin could stem from developmental compensations rather than the immediate absence of the receptor in adulthood. To sort this out, the researchers note that future experiments should test whether temporarily blocking this glutamate receptor with a drug in genetically typical adult mice produces the same heightened sensitivity to psilocybin.

    Second, although the head-twitch response is a reliable marker of serotonin 2A receptor activation in rodents, it is not a direct measure of subjective hallucinations, psychosis, or mystical-type experiences in humans. The authors caution that the restoration of sensory filtering in female mice does not mean psilocybin acts as a broad antipsychotic, and the amplified acute reactions in receptor-deficient mice point to the need for continued caution regarding psychedelic use in people vulnerable to psychosis.

    “Our findings do not establish whether psilocybin would benefit or harm people with schizophrenia, and they should not be interpreted as a recommendation for self-treatment,” Gattuso emphasized. “We examined one dose in one mouse model, and no animal model can reproduce the full complexity of the human disorder. Studying complementary models and a range of doses will help establish how robust and generalizable these findings are. That work could help inform whether, and under what conditions, carefully controlled clinical trials would be justified.”

    Finally, the study tested only a single dose level of psilocybin and did not measure blood or brain concentrations of psilocin, leaving open the possibility that male and female mice or different genotypes metabolize the compound at different rates. The researchers suggest that future studies should test multiple doses and examine whether giving a compound that blocks serotonin 2A receptors prior to psilocybin eliminates the acute head twitches while preserving the long-term sensory filtering improvements in females.

    “Ultimately, we want to understand where psilocybin might have therapeutic value, where it might carry risks, and which biological factors influence those outcomes,” Gattuso added. “Important next steps include investigating the mechanisms behind the sex differences and determining whether the longer-lasting improvements can be separated from the acute psychedelic-like responses. Our broader goal is to help advance psychedelic medicine through a clearer understanding of who might benefit, who might be vulnerable, and why.”

    The study, “Psilocybin produces amplified acute responses and sex-specific long-term increases in sensorimotor gating in the mGlu5 knockout mouse model of schizophrenia,” was authored by James J. Gattuso, Ahmed Kamal, Jennyfer M. Payet, Kato Havaux, Jenna Hendey, Bilgenur Bezcioglu, Zoe J. Phelan, Maddy Orchard, Divyesh Bhanot, Matthew W. Hale, Anthony J. Hannan, and Thibault Renoir.

    TITLE: Could psychedelics aid therapy for personality disorders? An unusual case offers a first look

    URL: psypost.org/could-psychedelics

    A new case report describes a 37-year-old woman with severe personality disorders and ADHD who improved markedly over a year of specialized psychotherapy, during which she also took psychedelic drugs on her own. By the end of the year, she no longer met the diagnostic criteria for narcissistic or paranoid personality disorder, and her borderline symptoms and emotional instability had eased. The report, published in Psychiatry Research Case Reports, raises the question of whether psychedelics might aid psychotherapy for personality disorders, a possibility the authors say needs testing in further pilot studies.

    Personality disorders are deeply ingrained patterns of thinking, feeling, and behaving that deviate from cultural expectations and cause severe distress or difficulty in daily life. People with these conditions often struggle with a distorted sense of self, extreme emotional swings, and turbulent relationships. Narcissistic personality disorder involves a fragile sense of self-esteem regulated through grandiosity or extreme vulnerability to criticism, while borderline personality disorder is marked by intense fears of abandonment, impulsive actions, and sudden shifts in mood.

    Paranoid personality disorder involves pervasive, unwarranted distrust and suspicion of others, while antisocial personality disorder involves a persistent disregard for the rights of others. Talk therapy remains the primary treatment for these conditions because no medications have been specifically approved to resolve core personality pathology.

    In recent years, psychiatrists and psychologists have begun exploring whether psychedelic substances like psilocybin and MDMA might help treat stubborn mental health conditions. This involves either macrodosing, where a patient takes a large dose to induce an intense, mind-altering experience, or microdosing, which entails taking tiny, repeated doses that do not cause hallucinations.

    The authors of a 2020 review made the case for researching psychedelics as part of treatment for borderline personality disorder, noting that the drugs may influence some of the same targets as existing therapies, including emotional control, self-compassion, and social functioning. Similarly, a study of clinicians noted trauma-related parallels between PTSD and borderline personality disorder, suggesting that the goals of MDMA-assisted therapy align closely with those of dialectical behavior therapy, a skills-based therapy developed for borderline personality disorder.

    Actual clinical data on using psychedelics for personality disorders has remained minimal. Before the new study, the only previously published case of its kind, to the authors’ knowledge, was a 2020 case report describing a 39-year-old woman with treatment-resistant depression and a complex personality disorder who received escalating weekly doses of LSD in a hospital setting. That patient experienced rapid reductions in emotional instability, depressed mood, and suicidal thoughts for about a week after each dose, even without experiencing acute hallucinogenic trips or receiving specialized talk therapy.

    To expand on this small body of evidence, Martin Blay of the ADDIPSY Outpatient Addictology and Psychiatry Center in Lyon and Université Paris-Saclay, alongside his colleagues Inès Benmakhlouf and Mario Speranza, documented the trajectory of a patient who combined structured psychotherapy with her own independent psychedelic regimen.

    The descriptive case report focuses on a 37-year-old woman, referred to as Mrs. P, who sought treatment at an outpatient center for severe personality pathology, ADHD, and cannabis use disorder. Mrs. P reported a history of severe physical and emotional abuse from her parents during childhood, as well as an attempted rape in 2016, and she was entirely estranged from her family. Her family medical history included two cases of schizophrenia in her grandmother and sister, bipolar disorder in her mother, and alcohol use and depressive disorders among other relatives. Her own psychiatric care began in 2009 after a suicide attempt, resulting in an initial diagnosis of bipolar disorder and over a decade of unsuccessful medication and psychoanalytic therapy.

    In late 2021, specialists revised her diagnosis to mixed personality disorder and ADHD, and she completed a year of dialectical behavior therapy without improvement before arriving at the authors’ clinic. At her initial intake, she was highly agitated, spoke rapidly, and reported severe emotional outbursts, frequent conflicts with her partner, suicidal behaviors, and deep mistrust and contempt toward others. The clinicians administered a battery of standardized interviews and questionnaires before treatment began and again after one year. At baseline, using the Structured Clinical Interview for DSM-IV Personality Disorders, she met the diagnostic thresholds for borderline, antisocial, narcissistic, and paranoid personality disorders.

    The treatment team proposed a weekly individual therapy program alongside a prescription for methylphenidate to manage her hyperactivity. The psychotherapy was based on Good Psychiatric Management, a structured approach that helps patients understand how their symptoms relate to interpersonal sensitivity and daily stressors. She also joined a six-week psychoeducation group for narcissistic personality disorder, an intervention previously developed and outlined in a 2024 proposal by all three of the study’s authors and their colleagues. Mrs. P initially refused all psychiatric medication, accepted the psychotherapy, and informed her clinicians during the first sessions that she had begun buying psychedelics online to self-administer alongside her therapy.

    Because of her family history of schizophrenia, the clinicians had serious safety concerns about her psychedelic use, as these substances can trigger psychotic episodes in vulnerable people. However, Mrs. P insisted she would take the substances regardless of their advice. To preserve the fragile therapeutic relationship and monitor her for any emerging signs of psychosis, the team agreed to proceed with the psychotherapy while discussing her experiences openly during sessions. Each weekly therapy session reviewed her recent emotional outbursts, practiced mentalizing (the ability to understand her own and others’ mental states and motives), linked her current reactions to past traumas, and set practical goals for emotional regulation.

    Over the course of her treatment, Mrs. P logged her psychedelic intakes, tracking the dates, doses, substances, and personal insights gained, while abstaining from cannabis and other drugs during the year. In most microdosing cycles she took a dose every two to three days, using small amounts of psilocybin truffles, an LSD analog called 1cP-LSD, or a mescaline analog called methallylescaline. Her eight macrodosing sessions involved larger amounts of psilocybin truffles, one dose of Amanita muscaria mushrooms, or MDMA, typically 100 to 130 milligrams. In one session, a weighing error led her to take 600 milligrams of MDMA, about five times her usual dose, resulting in an overly intense experience accompanied by temporary side effects including a rapid heart rate, anxiety, and impaired physical coordination, though she did not seek medical care.

    After one year of this combined regimen, psychometric testing showed substantial reductions across multiple symptoms. On the structured diagnostic interview, her narcissistic criteria fell from five to none and her paranoid criteria from four to one, so she no longer qualified for either diagnosis. Her borderline criteria fell from eight to five and her antisocial criteria from six to four, still enough for both diagnoses. Her scores for avoidant and obsessive-compulsive personality disorder criteria remained unchanged at one and three.

    Symptom severity scales echoed these diagnostic shifts. Her borderline symptom severity dropped by 72.2 percent on the self-reported Borderline Symptom List (from 3.13 to 0.869 on a 4-point scale) and by 68.8 percent on the clinician-administered Zanarini Rating Scale (from 16 to 5 on a 36-point scale), shifting her borderline symptoms from high or moderate down to moderate or mild. Measures of pathological obsessive-compulsive traits and covert narcissism also declined by about 20 to 32 percent. Her scores on a brief pathological narcissism inventory, which were already within the normal range at baseline, showed a modest reduction in vulnerable narcissism and almost none in grandiose narcissism.

    Measures of emotional and social functioning also improved over the year. Her difficulties with emotion regulation decreased by 29.1 percent (from 127 to 90), and her impulsivity score dropped by nearly 12 percent. Her score on the Toronto Alexithymia Scale (which measures alexithymia, the difficulty recognizing and describing one’s own emotions) dropped by 28.3 percent, moving her out of the possible-alexithymia range. Her social functioning frequency rose by 24.1 percent and her social satisfaction increased by 85.7 percent (from 21 to 39 out of 40), though her overall functional impairment on the Sheehan Disability Scale changed little, moving from 27 to 25 out of 30.

    Clinically, Mrs. P stopped having suicidal crises and began viewing her intense mistrust of others as an outdated defense mechanism rooted in childhood trauma rather than an objective reality. Her ADHD hyperactivity remained pronounced, and she had to rely on daily organizational strategies to avoid exhaustion after briefly trying and stopping stimulant medication. The authors hypothesize that the psychedelic intakes facilitated her progress in therapy, noting that her major interpersonal breakthroughs in sessions closely followed her macrodosing experiences, though they emphasize that this idea remains highly speculative and should be considered with the utmost caution.

    In her own written perspective, Mrs. P recalled her mindset before treatment: “I was like an injured wild animal, like ‘me against the whole world.'” She credited the psychedelics with shifting her out of emotional dissociation and helping her replace shame and guilt with self-compassion, while crediting the non-judgmental psychotherapy with helping her integrate those lessons and trust other people.

    Aspects of Mrs. P’s progress align with several earlier studies on psychoactive substances, though those studies used different designs and populations. Her reductions in narcissistic traits parallel a 2020 survey of the general population, which examined self-reported traits rather than clinical personality disorder symptoms in a psychotherapy patient, and found that awe-inspiring psychedelic experiences were associated with lower maladaptive narcissism. Her reductions in borderline symptoms also align with a clinical study of depressed patients with borderline personality disorder that observed symptom improvements following intravenous ketamine infusions rather than classic psychedelics.

    Additionally, a 2024 prospective survey of adults microdosing for ADHD found that microdosing was associated with reductions in ADHD symptoms and one aspect of emotion regulation over four weeks compared to conventional medication. That survey relied on online self-reports rather than a clinical case combining micro- and macrodosing with talk therapy. While Mrs. P similarly showed improvements in emotion regulation and impulsivity, her core hyperactive ADHD symptoms persisted throughout the year.

    At the same time, this single positive outcome stands in tension with broader safety data regarding personality disorders and psychedelic use. In a 2024 observational study that tracked general drops in mental wellbeing across mostly unsupervised and recreational psychedelic use rather than structured, specialized psychotherapy, 16 percent of all participants reported worse mental health afterward, and people with a history of personality disorders accounted for a disproportionate 31 percent of those negative outcomes.

    The case report’s authors cite this research as showing roughly a fourfold higher risk of worsening mental health among people with personality disorders. Although the authors acknowledge that no such worsening occurred in Mrs. P’s case, they also point to a phase 2 trial of psilocybin for treatment-resistant depression in which all three participants who showed suicidal behavior after receiving the highest dose had a history of suicide attempts or self-injury, a pattern the authors suggest may indicate underlying personality disorders.

    There are several other caveats to keep in mind when interpreting this case report. Because Mrs. P chose the timing, substances, and doses on her own without supervised drug sessions, her care cannot be classified as standard psychedelic-assisted psychotherapy, and it is impossible to separate the effects of the drugs from the effects of the talk therapy. As the authors note, Mrs. P might have achieved these same improvements through the specialized psychotherapy and strong therapeutic alliance alone.

    Other factors could explain her progress. People who enter treatment in crisis often improve from that low point regardless of the intervention, and stopping cannabis use (one of the reasons she was referred for care) may by itself ease mood swings, impulsivity, and the kind of suspiciousness reflected in her drop from four paranoid criteria to one. Her enthusiasm for psychedelics could have shaped her questionnaire answers, and the acknowledgments thank her for helping write the paper. In addition, case reports tend to be written up when outcomes are good, whereas patients in similar situations who got worse would be unlikely to produce a paper like this.

    Questions also surround the drugs she took and the timeline of her use. The substances she bought online were never tested, so their actual content and doses cannot be verified. The paper’s dates also conflict: the text says her therapy began at the end of 2023, yet her psychedelic log starts in September 2022 and includes overlapping cycles and out-of-order entries. That makes it unclear whether she started psychedelics before therapy or how much of her use fell between the two assessments.

    The authors further note that Mrs. P’s case does not reflect typical psychiatric patients, who frequently take daily prescription medications. Aside from her brief trial of methylphenidate, she took no psychiatric medications while using psychedelics. Combining psychedelics with some psychiatric drugs can trigger severe medical emergencies, such as seizures when mixed with lithium or dangerous spikes in blood pressure when combined with monoamine oxidase inhibitors, an uncommon class of antidepressants.

    The researchers suggest that further pilot studies are needed to test whether combining psychedelics with psychotherapy could be safe and useful for patients with personality disorders.

    The study, “Could psychedelics be useful in the treatment of patients with personality disorder? A case report of psychotherapy with concomitant use of psychedelics,” was authored by Martin Blay, Inès Benmakhlouf, and Mario Speranza.

    TITLE: Schizophrenia is linked to broad difficulty reading emotions from body language and faces

    URL: psypost.org/schizophrenia-is-l

    A small study of men in Germany found that those with schizophrenia were less accurate than healthy men at recognizing emotions from both body movements and facial expressions shown as simple moving dots. Among the men with schizophrenia, those who were better at reading emotions from body movements also tended to be better at reading them from faces, a link that did not appear in healthy men. The paper was published in Schizophrenia.

    Understanding other people’s emotions, intentions, and social signals is a basic skill that helps us navigate everyday interactions. In typical individuals, the brain combines information from faces, body movements, and other cues to build a picture of what someone else may be feeling or thinking. In people with mental disorders, however, this process can become less reliable.

    Different disorders appear to produce different patterns of difficulty. In depression and bipolar disorder, problems tend to affect the recognition of particular emotions, such as sadness, rather than social cognition, the mental processes involved in perceiving and understanding other people, as a whole. Schizophrenia, by contrast, is associated with broader problems in interpreting nonverbal social information. People with schizophrenia tend to have difficulty reading emotions from the eyes, facial expressions, and body movements, which can make social relationships harder to establish and maintain.

    Researchers often study these abilities using point-light displays, in which only a handful of moving dots, placed on a person’s joints or face, represent the body or face. Because viewers see only motion, emotion recognition can be tested without cues such as clothing, body shape, or facial features. While healthy individuals can usually recognize emotions from these simplified displays, people with schizophrenia tend to perform less accurately.

    Study author Annika Resch of the University of Tübingen and colleagues examined whether men with schizophrenia differ from healthy men in recognizing emotions from point-light faces and bodies. Because schizophrenia differs between men and women in how common it is, when it starts, and how severe it tends to be, the researchers included only men to reduce variability. They also wanted to know whether any difficulties were global, affecting all tasks and emotions, or selective, affecting only some, and whether people’s performance on the face and body tasks was related.

    The participants were 28 men diagnosed with schizophrenia or related disorders, recruited from inpatient units at the University Hospital Tübingen, and 28 healthy men from the local community who were matched to them in age. Participants’ average age was 32 years. Most of the patients had been diagnosed with paranoid schizophrenia, and eight had schizoaffective disorder, a condition that combines symptoms of schizophrenia with those of a mood disorder. Nearly all of the patients were taking medication, and more than half had other conditions, mostly involving substance use.

    In the body task, participants watched 2-second videos of a walking figure made of 15 white dots placed on the head, neck, pelvis, and major joints of an otherwise invisible body. In each of 144 trials, they pressed a key to indicate whether the walker’s movement expressed anger or was emotionally neutral. The walkers were based on recordings of four actors, two men and two women.

    In the face task, participants watched 2-second videos of faces represented by 50 white dots and indicated whether each face expressed happiness or anger. This task included 108 trials featuring six actors, three men and three women. The researchers recorded both how accurately and how quickly participants responded.

    Men with schizophrenia were less accurate than healthy men on both tasks, and the gap was especially large for faces. On the face task, they correctly identified the emotion about 59% of the time, compared with 76% for healthy men; on the body task, the figures were about 55% and 63%, where 50% would reflect random guessing. Men with schizophrenia were also slower to respond on both tasks.

    Both groups were more accurate with faces than with bodies. The body task proved difficult for everyone, mainly because angry walking was hard to recognize: on angry walkers, the two groups did not differ, while men with schizophrenia were less accurate at recognizing neutral walking. On the face task, men with schizophrenia were less accurate at recognizing both happy and angry expressions.

    The researchers describe the impairment as global because men with schizophrenia showed the same overall pattern as healthy men, finding the same emotions easier or harder to recognize, just at a lower level of accuracy. Among men with schizophrenia, those who were more accurate on the body task also tended to be more accurate on the face task, but this link was absent in healthy men. In both groups, people who responded quickly on one task also tended to respond quickly on the other.

    “For SZ [schizophrenia] patients, inferring social signals from dynamic faces and bodies may be rather challenging in terms of neurocognitive mechanisms, which is reflected in the tight link in recognition accuracy. Along with previous data on inferring emotions in the eyes collected in the same cohort, this work provides novel insights into the specific global aberrations in social cognition in SZ and offers a blueprint for the development of strategies for the targeted treatment of gender-specific mental disorders,” study authors concluded.

    In other words, the authors suggest that schizophrenia may affect a shared set of mental processes involved in reading both faces and bodies, so that difficulties with one tend to go along with difficulties with the other.

    The study contributes to the scientific understanding of social cognition in people with schizophrenia. However, it should be noted that the study was conducted on a relatively small sample of participants and used a very small number of emotional expressions. Results on larger samples and using a wider range of emotions might differ.

    The study included only men, so it is not known whether the findings apply to women with schizophrenia. Nearly all patients were taking medication and many had other conditions, which could have affected their performance. The authors also note that it remains unknown whether the difficulties reflect problems specific to social cognition or broader cognitive difficulties associated with schizophrenia.

    The paper, “Reading body and face language in male schizophrenia,” was authored by Annika Resch, Alexander N. Sokolov, Patrick Steinwand, Andreas J. Fallgatter, and Marina A. Pavlova.

    TITLE: Socially isolated and lonely people tend to be biologically older than their years

    URL: psypost.org/socially-isolated-

    Socially isolated and lonely adults tend to have an older biological age than their chronological age would predict, and they face a higher risk of death, according to a study of more than 300,000 people in the United Kingdom published in Health Psychology. People who were both isolated and lonely showed the greatest gap between biological and chronological age.

    Two people born on the same day can experience very different rates of physical decline. While chronological age simply tracks the number of years since birth, biological age measures the physiological condition of a person’s cells, tissues, and organ systems. When an individual’s biological age is higher than their chronological age, researchers refer to the gap as biological age acceleration, a state that predicts a higher risk of chronic illnesses and earlier death.

    Social isolation and loneliness are two distinct forms of social disconnection that may influence this physiological wear and tear. Social isolation is an objective lack of contact with other people, characterized by living alone, seeing family or friends less than once a week, and staying away from community groups. Loneliness is the subjective emotional distress of feeling detached from others or lacking someone to confide in, which a person can experience even when surrounded by people.

    Because the two do not always overlap, the authors note that simply increasing social contact may not fully offset the health risks tied to loneliness, and vice versa. Both forms of disconnection are thought to take a toll on the body through chronic psychological stress, poorer health habits, and immune system disruption. For example, a large longitudinal study drawing on the same UK Biobank cohort found that loneliness and social isolation were linked to elevated blood levels of specific inflammation and immune proteins, which in turn tracked with higher rates of heart disease, stroke, diabetes, and death over a 14-year follow-up.

    The study was led by co-first author Rui Mao, a resident physician, assistant researcher, and postdoctoral researcher in the Department of Dermatology at Xiangya Hospital of Central South University. Corresponding author Xin Meng is a resident physician and assistant researcher in the Department of Dermatology at the First Affiliated Hospital of the University of South China and Xiangya Hospital of Central South University. Along with colleagues from several other Chinese medical institutions, they examined how social isolation and loneliness independently and jointly relate to biological age acceleration, whether genetic predisposition to biological aging modifies this relationship, and whether biological age acceleration helps link social disconnection to mortality.

    “Our research focuses on aging and the factors that shape health across the lifespan,” Mao and Meng told PsyPost. “Social isolation and loneliness have been linked to poorer health, but their relationship with biological aging, particularly when they occur together, remains less clear. We wanted to understand whether having fewer social connections and feeling lonely were each associated with an older biological profile.”

    To investigate these questions, the researchers analyzed data from 309,746 adults enrolled in the UK Biobank, a large national health database in the United Kingdom. The participants had an average age of about 56 at the start of the study, and 54 percent were female. They were recruited between 2006 and 2010 and had their health and survival tracked until July 2023, for a median follow-up period of 14.4 years. The study was a secondary analysis of existing cohort data, and no preregistration was reported.

    At the initial assessment, participants completed questionnaires measuring their social habits and feelings. The researchers scored social isolation on a scale from 0 to 3, assigning one point each for living alone, visiting friends or family less than once a week, and not participating in weekly group activities such as sports clubs, religious groups, social clubs, or adult education classes. At baseline, 40 percent of participants had a moderate isolation score of 1, and 14 percent had a high isolation score of 2 or 3. Loneliness was scored from 0 to 2, with one point given for often feeling lonely and one point for almost never confiding in someone close; 4 percent of participants scored the maximum of 2 points and were classified as lonely.

    To measure biological age, the scientists used an established clinical formula called PhenoAge, which estimates physiological age from routine blood biomarkers, including markers of inflammation and organ function. Biological age acceleration was calculated as how much older or younger a participant’s PhenoAge was than expected for their actual age. The team also calculated a polygenic risk score for each participant, which summarizes their inherited genetic predisposition toward biological age acceleration based on variations in their DNA.

    In statistical models that controlled for age, sex, race, income, education, neighborhood deprivation, body mass index, smoking, alcohol use, physical activity, grip strength, diet, sleep patterns, sun exposure, and personal history of diabetes, cardiovascular disease, hypertension, stroke, and cancer, both forms of disconnection were tied to an older biological age. Each one-point increase on the social isolation scale corresponded to a 0.17-year increase in biological age acceleration, while each one-point increase on the loneliness scale corresponded to a 0.15-year increase. Compared to the least isolated participants, those in the most isolated group showed 0.33 years more biological age acceleration, or roughly four months. Participants classified as lonely had 0.24 years more biological age acceleration, or about three months, compared to those who were not lonely.

    “These are modest average differences in an aging indicator, rather than estimates of months of life lost or predictions for an individual,” the researchers explained. “Their potential relevance lies in what they may reveal about social conditions and health across a large population.”

    The authors note that their fully adjusted estimates likely understate the overall association, because some of the factors they controlled for, such as smoking, sleep, and chronic disease, may themselves be pathways linking social disconnection to aging. Accounting only for demographic and socioeconomic factors, the most isolated group was about seven months older biologically and the lonely group about nine and a half months older.

    Looking at the individual survey questions in the fully adjusted model, living alone was associated with 0.27 years of biological age acceleration, lacking someone to confide in with 0.22 years, not taking part in weekly social activities with 0.17 years, often feeling lonely with 0.14 years, and having infrequent visits from friends or family with 0.09 years. When the researchers looked at social isolation and loneliness together, they found an additive pattern, meaning that people who were both highly isolated and lonely had the greatest biological age acceleration.

    “One finding that stood out was the association between limited emotional support and biological age acceleration,” Mao and Meng noted. “Not having someone to confide in showed an association at least comparable in magnitude to reporting feelings of loneliness. This reinforces the importance of looking beyond the number of social contacts to whether people have relationships in which they feel supported.”

    When the researchers incorporated the genetic data, they did not detect a statistically significant interaction between genetic risk and social disconnection, meaning that isolation and loneliness did not multiply the effect of aging-related genes. However, the genetic and social risks stacked on top of one another. Compared to people with low genetic risk and minimal isolation or loneliness, participants who had both a high genetic risk for biological age acceleration and high social isolation were biologically older by roughly 1.7 years, while those with high genetic risk and loneliness were biologically older by about 1.85 years. For comparison, isolation and loneliness on their own were tied to gaps of about four and three months.

    Subgroup analyses also indicated that the link between loneliness and biological age acceleration was stronger among men, people under age 60, those with lower incomes, people who never smoked, and those with unhealthy sleep habits. The association between social isolation and biological age acceleration did not vary significantly by sex, body mass index, or sun exposure.

    To address the possibility that poor health causes people to withdraw socially rather than the other way around, the researchers also performed a two-sample Mendelian randomization analysis, which uses genetic variants associated with behavioral traits to test for a directional link to health outcomes. Because these genetic variants are fixed at conception, they are not affected by later health problems, which reduces the chance that poor health is driving the association. In this analysis, a genetic liability toward loneliness was positively associated with biological age acceleration, while genetic tendencies toward regular attendance at a gym or sports club and involvement in a religious group were associated with lower biological age acceleration. Genetic predisposition toward visiting a pub or social club did not have a statistically significant association with biological age acceleration.

    Finally, the team examined death records over the 14.4-year follow-up period. Each one-point increase in the social isolation score was associated with a 13.9 percent higher risk of dying from any cause, and each one-point increase in the loneliness score was associated with an 8.9 percent higher risk of death from any cause. Both traits were also associated with higher rates of death specifically from coronary artery disease and cancer.

    An exploratory mediation analysis examined whether biological age acceleration sat on the pathway between social disconnection and mortality. Under the model’s assumptions, only about 5.2 percent of the link between isolation and death, and 7.2 percent of the link between loneliness and death, was statistically attributable to biological age acceleration.

    These findings align with a Mayo Clinic study that gauged biological age from artificial intelligence readings of heart electrocardiograms rather than blood tests, which likewise linked social isolation to accelerated biological aging and a higher risk of death. They also fit with a study of older Chinese adults that tied poorer psychological well-being, including loneliness and unhappiness, to older biological age, though that study measured loneliness as part of a broader well-being scale.

    The authors suggest that different types of group activities may relate to biological aging through different channels. They propose that sports clubs and gyms may help because they incorporate regular physical exercise, whereas religious participation has been linked to lower rates of depression and better self-rated health. Because genetic risk and social disconnection operated independently rather than interacting, the researchers also note that reducing loneliness and isolation could benefit people across all levels of inherited genetic risk.

    “Our findings suggest that social connection deserves attention when we think about healthy aging,” the researchers said. “Having people around and feeling emotionally connected are different experiences, so opportunities for social contact and access to meaningful support both deserve consideration. These findings provide a reason to take social well-being seriously, although they do not establish that increasing social contact will reverse aging.”

    As with all research, there are some caveats to consider when interpreting these results. Even with more than a decade of mortality follow-up, reverse causality cannot be ruled out, since people experiencing worse physical decline may become less able to socialize or more prone to feeling lonely.

    “The main caution is that our findings should not be interpreted as proof that loneliness directly causes aging or that joining a social group will make someone biologically younger,” Mao and Meng told PsyPost. “Biological age was assessed at one time point, so we could not track how individuals’ aging trajectories changed as their social circumstances changed. Our genetic analyses provided complementary evidence, but they also depend on assumptions and cannot replace intervention trials.”

    Those genetic instrument analyses carry several specific constraints. No genetic summary data were available for the complete social isolation score, so the Mendelian randomization could only test individual habits like gym or religious attendance rather than overall isolation. In addition, genetic variants linked to habits like gym attendance may influence biological aging through other biological pathways rather than through social participation itself, genetic proxies do not perfectly mirror actual survey responses, and the estimate linking genetic liability for loneliness to biological aging had a wide margin of error.

    Finally, the questionnaires used in the UK Biobank relied on just a few brief items to capture loneliness and isolation and did not account for marital status in the index. The participant pool was also predominantly of European ancestry and drawn from the United Kingdom, meaning the results may not automatically generalize to other cultural environments where family structures and community norms differ.

    Because the team studies aging from a dermatology perspective, their interests extend to how aging shows up in tissues like the skin. “Our broader goal is to identify potentially modifiable factors associated with biological aging and understand their relevance to health, including skin health,” the researchers explained. “An important next step would be to examine whether changes in social connection are followed by changes in biological aging, using repeated measurements and more diverse populations. Ultimately, intervention studies are needed to test whether reducing loneliness or improving social support can produce measurable biological benefits.”

    “We hope this study encourages a more compassionate understanding of loneliness and social isolation,” Mao and Meng added. “Social circumstances are shaped by health, mobility, caregiving responsibilities, and access to community resources, so the implications extend beyond individual choices. Our findings support further investigation of social connection as part of the broader conditions that enable healthy aging.”

    The study, “Social Isolation, Loneliness, and Biological Aging Acceleration,” was authored by Rui Mao, Jiao Yuan, Tongtong Zhang, Fan Wang, Yun Zhong, Haonan Yuan, Fan Yang, and Xin Meng.

    TITLE: Brain structure carries clues about who prefers instant gratification, study suggests

    URL: psypost.org/brain-structure-ca

    A brain imaging study of 146 young adults suggests that machine learning models can partly predict how strongly a person favors immediate rewards over larger future ones, using only the volumes of specific brain regions. Regions involved in reward processing and long-term planning featured prominently in the predictions. The findings, published in JAMA Psychiatry, offer early proof-of-concept evidence that brain structure carries information about impulsive decision-making.

    In everyday life, people regularly weigh smaller, immediate rewards against larger benefits that require waiting, such as spending money right away versus saving for the future. Psychologists refer to the tendency to reduce the subjective value of a reward the longer one has to wait for it as delay discounting. A person who prefers $20 today over $50 in a month exhibits steep delay discounting, which serves as a behavioral measure of impulsivity and short-sighted decision-making.

    Patterns of delay discounting vary widely from person to person and appear at extreme ends of the spectrum across several mental health conditions. Steep discounting is characteristic of disorders involving impulse-control challenges, including substance use disorders, attention-deficit/hyperactivity disorder (ADHD), bulimia nervosa, and borderline personality disorder. By contrast, unusually low discounting, which indicates a strong preference for delayed rewards over immediate ones, is observed in people with anorexia nervosa and in older adults with higher suicidal tendencies.

    Because this decision-making trait cuts across different diagnoses, it aligns with the Research Domain Criteria (RDoC) framework, a psychiatric research model that examines mental health along continuous dimensions of behavior and biology rather than strict diagnostic categories. Research suggests that discounting can be shifted in experiments, which makes it a potential target for treatment. Discounting also has practical stakes: a neuroimaging study of adult smokers found that those with steeper discounting were more likely to relapse after smoking-cessation treatment, and showed differences in brain activity in regions tied to decision-making and habit formation.

    Most brain imaging research on impulsive choice has focused on functional activity or communication between brain networks during decision-making tasks. Along these lines, a brain imaging study of adolescents found that stronger moment-to-moment coupling between the amygdala, an emotional hub, and the brain’s cognitive control network predicted a greater preference for immediate rewards, but only among 14- to 17-year-olds making choices about high-value rewards. However, it remains unknown whether the brain’s physical structure, which changes far more slowly than its activity, can reliably indicate a person’s typical level of delay discounting.

    Physical brain tissue is broadly divided into two main components that make up the brain’s macrostructural, or large-scale, anatomy: gray matter and white matter. Gray matter consists primarily of neuronal cell bodies located in the brain’s folded outer layer and deep internal structures that process information, whereas white matter consists of bundles of insulated nerve fibers beneath the surface that connect different gray matter areas to one another.

    To test whether machine learning could detect signals of individual delay discounting from the volume of these two tissue types, co-first authors Bryan Youngwoo Yoon of Columbia University Irving Medical Center and Wonjin Kim of Yonsei University conducted an initial proof-of-concept study alongside senior authors Joon Yul Choi of Yonsei University and Wi Hoon Jung, an associate professor of psychology at Gachon University in Seongnam, South Korea.

    “Despite growing interest in the neural mechanisms underlying impulsive decision-making, we still know relatively little about how individual differences in delay discounting are reflected in the brain’s macrostructural anatomy,” Jung told PsyPost. “First, although previous research has highlighted the involvement of distributed brain networks in decision-making, the specific contributions of regional gray matter and white matter volumes remain insufficiently understood. Second, we wanted to determine whether machine learning could identify meaningful structural patterns from conventional structural MRI data and use them to predict individual differences in delay discounting. Our goal was to explore whether brain structure could provide useful information about how people balance immediate rewards against future benefits.”

    The researchers analyzed behavioral and neuroimaging data collected between July 2020 and July 2023 from 146 college-aged participants, who had an average age of about 22.6 years and included 75 females and 71 males. Each participant completed a behavioral delay discounting assessment and underwent a T1-weighted magnetic resonance imaging (MRI) scan, a standard structural scan that uses magnetic fields and radio waves to generate detailed three-dimensional images of brain anatomy.

    Using a standardized anatomical atlas, the team extracted the volumes of gray matter and white matter across predefined brain subdivisions, known as regions of interest. To control for natural differences in overall head size across participants, every regional volume was normalized to the person’s total intracranial volume, which represents the total space inside the skull cavity.

    To train and test their predictive algorithms, the authors generated five independent random splits of the dataset, placing 80% of the participants into a training set and holding out the remaining 20% as a testing set. Within each 80% training set, the team used generalized linear models, a statistical method for estimating relationships between variables, to identify brain regions whose volumes were statistically associated with delay discounting after adjusting for age and sex assigned at birth. The researchers then ran an exhaustive subset search across those candidate regions, systematically testing every possible combination of brain areas to find the specific subset that best estimated delay discounting.

    The optimal combinations of gray matter or white matter regions were fed into a multilayer perceptron model to predict delay discounting scores in the held-out 20% test sets. A multilayer perceptron is a type of artificial neural network used in machine learning that passes input data through multiple interconnected layers of mathematical nodes, allowing it to detect complex patterns across multiple brain regions at once. The researchers built and evaluated separate neural network models for white matter volumes and gray matter volumes.

    Across the five testing splits, both the white matter model and the gray matter model estimated individual delay discounting scores with moderate accuracy. The white matter model achieved an average R-squared value (the proportion of variance in an outcome accounted for by a model) of 0.22, with a standard deviation of 0.11, indicating that white matter volumes in the selected regions accounted for an average of 22% of the variation in delay discounting. The gray matter model reached an average R-squared value of 0.19 (with a standard deviation of 0.10), accounting for an average of 19% of the variation in delay discounting.

    “The predictive performance was moderate but meaningful for a study attempting to estimate a complex behavioral trait from brain structure alone,” Jung explained. “First, these results indicate that regional brain volumes contain information relevant to individual differences in delay discounting. Second, the models did not explain all of the variability, which is unsurprising given that decision-making is influenced by many interacting factors, including brain structure, functional brain activity, genetics, and environmental experiences. We therefore see these findings as evidence that structural MRI can contribute to understanding and predicting impulsive decision-making, rather than as evidence that brain anatomy alone can accurately explain complex behavior.”

    When the researchers examined which specific brain structures drove the predictions, they found that two areas in the right hemisphere were selected in both the white matter model and the gray matter model. One was the right accumbens area, a structure deep inside the brain’s ventral striatum that plays a central role in processing reward, pleasure, and motivation. The other was the right frontal pole, situated at the frontmost tip of the frontal lobe, which supports future planning, weighing long-term consequences, and goal-directed decision-making.

    The white matter model also drew on four other regions, mostly involved in sensory and visual processing, while the gray matter model added seven more, including frontal areas tied to self-control and parts of the visual cortex. The paper does not report whether larger or smaller volumes in these areas went with steeper discounting.

    The authors point out that the most informative structural features consistently mapped onto the frontolimbic circuit, a brain network that connects frontal planning hubs with deep reward centers, while also implicating sensory and temporal areas that are less commonly highlighted in impulse-control research. Because the white matter model outperformed the gray matter model, the researchers suggest that the macroscopic volume of white matter pathways may be just as important as the volume of gray matter processing hubs in regulating impulsive choices. In the authors’ reading, the accumbens area and frontal pole could represent structural targets for psychiatric conditions characterized by impaired impulse control.

    “The main message is that differences in how people weigh immediate rewards against future benefits may be reflected, at least in part, in the structure of their brains,” Jung said. “These findings suggest that individual differences in impulsive decision-making may be associated with structural characteristics of brain regions involved in balancing immediate rewards with longer-term goals.”

    Jung noted that one unexpected aspect of the results was that the white matter model outperformed the gray matter model. “Much of the neuroimaging literature on impulsivity has focused on gray matter regions involved in reward processing and cognitive control,” he told PsyPost. “Our results suggest that white matter volume may also provide valuable information about individual differences in delay discounting.”

    “This was an interesting finding because it highlights the potential importance of considering both tissue types when investigating the structural basis of decision-making,” he added. “At the same time, because our white matter measures reflected regional tissue volumes rather than direct measures of fiber integrity, further research will be needed to clarify the underlying mechanisms.”

    There are a few things to keep in mind when interpreting these findings. The authors framed their work as an initial proof-of-concept study, and the analysis relied on a modest sample of 146 college-aged young adults scanned using a single MRI scanner. Although the machine learning models were evaluated on held-out portions of the dataset, they have not yet been tested on an independent external sample or across diverse age groups and clinical populations.

    In addition, the models accounted for an average of 19% to 22% of the variation in delay discounting, which the authors describe as in line with the medium effect sizes typical of brain-based predictions of behavior. That still leaves most individual differences unexplained. Each test set included only about 29 people, and accuracy varied considerably from split to split, so the estimates could shift in a larger sample.

    The cross-sectional nature of the study also means that brain anatomy and delay discounting were measured at a single point in time. Because of this design, the results cannot establish whether structural volume differences in the accumbens area or frontal pole cause people to favor immediate rewards, or whether long-standing behavioral habits and environmental factors gradually shape brain tissue volume. At the same time, the study relied solely on T1-weighted structural MRI scans, meaning the white matter measurements reflect bulk tissue volume within or next to defined brain regions rather than the microscopic integrity or organization of nerve fiber bundles.

    “These measures do not directly assess the microstructural integrity of white matter fibers, as diffusion MRI measures such as fractional anisotropy or tractography-based analyses attempt to do,” Jung pointed out. “Future studies combining these approaches may provide a more comprehensive understanding of the structural basis of delay discounting.” In neuroimaging, diffusion MRI methods such as fractional anisotropy and tractography track the movement of water molecules along nerve fibers to map their microscopic alignment and wiring pathways.

    “Our findings should not be interpreted as suggesting that brain scans can determine how an individual will behave,” Jung added. “The models identify statistical patterns associated with delay discounting, not fixed biological traits that dictate behavior. Delay discounting can vary with circumstances and may change through learning or intervention. Our findings therefore point to potential neural correlates of individual differences, rather than a deterministic explanation of impulsivity.”

    To expand on this work, the researchers suggest validating their models in larger, external cohorts across multiple research sites and integrating different types of brain imaging data. Future studies could combine structural and diffusion scans with resting-state functional connectivity, which measures how brain regions coordinate their activity while a person is at rest. Combining these approaches could help scientists determine whether structural brain markers of delay discounting can aid in early diagnosis or inform personalized interventions for psychiatric disorders.

    “Combining structural T1-weighted MRI with diffusion MRI measures and resting-state functional connectivity could provide a more comprehensive picture of how brain anatomy and connectivity relate to delay discounting,” Jung said. “Such an approach may also help explain why white matter volumes showed stronger predictive performance than gray matter volumes in the present study.”

    The team also hopes to test these neuroimaging models in clinical groups. By uniting computational brain imaging with behavioral economics, a field that studies how psychological factors shape financial and personal choices, researchers aim to better understand impulse-control challenges across different diagnoses.

    “We are interested in extending this work to clinical populations, including individuals with substance use disorders, eating disorders, and ADHD,” he said. “By examining whether the identified structural patterns are also relevant in these groups, we hope to determine whether neuroimaging-based measures of delay discounting could eventually contribute to identifying behavioral risk profiles or monitoring responses to targeted interventions. However, their clinical usefulness would need to be established through careful external validation and prospective studies.”

    “One aspect of this study that we find particularly valuable is the opportunity to bring together behavioral economics and computational neuroimaging to investigate a clinically relevant dimension of behavior,” Jung concluded. “Rather than treating impulsivity solely as a symptom associated with a particular diagnosis, we approached delay discounting as a continuous behavioral characteristic within the RDoC framework.”

    “We believe this dimensional perspective may help researchers better understand why people differ in their decision-making, both within and across psychiatric diagnoses. Although our findings represent an early step rather than an immediate clinical application, they demonstrate the potential of combining theoretically grounded behavioral measures with machine learning to investigate the relationship between brain structure and complex human behavior.”

    The study, “Structural Brain Volumes and Delay Discounting,” was authored by Bryan Youngwoo Yoon, Wonjin Kim, Dohyeon Kim, Joon Yul Choi, and Wi Hoon Jung.

    TITLE: House Republicans accuse the American Psychological Association of tolerating antisemitism

    URL: psypost.org/house-republicans-

    House Republicans on the Education and Workforce Committee have released an investigative report accusing the American Psychological Association (APA) of allowing antisemitism to fester within its ranks, appeasing anti-Israel activists, and dismissing the concerns of Jewish psychologists.

    The report, released on October 29, 2026, by Committee Chairman Tim Walberg (R-MI), is the product of an investigation opened in December 2025. In it, the committee alleges that over several years, “radical activist-academics” have co-opted the nation’s leading professional organization for psychologists to promote political ideologies that demonize Israel, minimize Hamas terrorism, and portray Jewish people as “white oppressors.”

    In a statement reported by The Hill, APA President Wendi Williams rejected the allegations, saying the association “unequivocally condemns antisemitism in all its forms.”

    “Since these concerns were first brought to APA’s attention, APA has taken meaningful steps to ensure that Jewish members, like all members, can participate fully and safely in the organization and the profession,” she said. According to Jewish News Syndicate, Williams and APA CEO Arthur C. Evans Jr. also emailed colleagues stating that the organization has held listening sessions with Jewish psychologists.

    During the period examined by the committee, the APA also passed a February 2026 resolution condemning antisemitism, though the House report sharply criticizes that measure as watered down, and published a May–June 2026 special issue of its flagship journal, American Psychologist, dedicated to “Antisemitism and Psychology.”

    “For an organization dedicated to understanding human behavior, the APA has done a remarkable job of ignoring prejudice within its own ranks,” Walberg said in a press release accompanying the report. “The APA has a credibility problem, and its leadership has no one to blame but itself.”

    The congressional findings arrive about a month after a Department of Education accreditation advisory committee voted 7–4 to recommend a one-year suspension of federal recognition for the APA’s Commission on Accreditation. According to a statement from the Anti-Defamation League (ADL), the advisory panel cited a failure to address a pervasive culture of antisemitism. Members of the Education Department committee also raised concerns over the APA’s support of “decolonial therapy,” an issue the House report similarly criticizes.

    In a published response, the APA said it firmly rejects the recommendation and urged the department to re-recognize its accrediting commission. Aaron Joyce, the executive lead psychologist for the APA Commission on Accreditation, disputed in a statement to Jewish Insider that there is a “pervasive culture of antisemitism,” noting the commission had received only two antisemitism complaints in accredited programs. The Department of Education has not yet issued a final ruling on the recommendation and is expected to decide in the coming months.

    Controversies over October 7 and internal communications

    A central focus of the House committee’s report is the APA leadership’s internal handling of the October 7, 2023, Hamas terrorist attacks on Israel. According to internal emails obtained by the committee, APA leaders consulted an affiliate group, the American Arab, Middle Eastern, and North African Psychological Association (AMENA-Psy), while drafting their public statement on the attacks. According to a footnote in the report, APA leadership stated it had been assured that AMENA-Psy accepts all Middle Eastern psychologists, including Israeli and Jewish members.

    While the committee’s press release states that AMENA-Psy demanded the removal of references to terrorism, the report details that AMENA-Psy leaders advised against the term. The group’s incoming president wrote that “[t]errorist attacks needs to change, there’s a lot of problematic and racist language in this that will upset MENA membership,” while its then-president wrote that “[t]errorism language is very one sided and overused with Arabs.” The APA’s final released statement did not reference terrorism. Days after October 7, AMENA-Psy, which the APA internally referred to as an “antisemitism stakeholder,” released its own statement that the report says described the Hamas attack as a justified “resistance action.”

    According to the committee’s report, internal communications also showed APA leaders echoing biased perspectives or dismissing antisemitism-related complaints. Days after October 7, Cynthia de las Fuentes, who would serve as APA president in 2024, internally compared Hamas’ terrorist attack to the death of George Floyd. She wrote that police in the Floyd context were equivalent to “believers of ‘by any means necessary’ in achieving the goals of Zionism, similar to other terrorist groups’ missions,” while stating that “George Floyd is representative of Gazans.”

    In another instance detailed by the committee, in response to a June 2025 exchange with a Jewish psychologist who wrote to leadership with grave concern about antisemitism, then-chief diversity officer Maysa Akbar replied internally, “Sigh!” Similarly, the 2021 APA president wrote “sigh………” to Akbar in response to a May 2025 letter about antisemitism from Rep. Ritchie Torres (D-NY). Furthermore, in spring 2025, after the medical advocacy group Do No Harm criticized antisemitism at the APA, then-senior director of strategic communications and public affairs Kim Mills wrote internally, “I wonder if the Jews who are so angry at us know they are now feeding hatred from this horrible group.”

    The report also notes that in 2024, the APA avoided a request to recommend trauma psychologists for a White House screening of Screams Before Silence, a documentary about Hamas’ sexual violence on and after October 7, with one official writing, “I fear providing some names might insert us into the politics of the film and audience.”

    The committee also criticized leadership’s praise of Lara Sheehi, former president of the APA’s psychoanalysis division, whose Jewish students at The George Washington University alleged in 2023 that she discriminated against them, and who has publicly claimed that Zionists have “psychosis.” After Sheehi emailed APA leaders praising their October 7 statement and claiming that those who do not recognize Israel’s “all out genocide” are experiencing “internalized racism,” 2023 APA President Thema Bryant praised Sheehi’s “heart, truth, challenge, and compassion.”

    The report notes the APA continued facilitating continuing education credits for sessions led or moderated by Sheehi as recently as February 2026. According to the report, the APA has responded to concerns about antisemitism by division leaders by pointing to its bylaws, saying it “does not, and cannot, censure” members or elected or appointed officials for their speech.

    Additionally, the report states that APA members turned division listservs into hostile and deeply antizionist forums after October 7, with posts defending the “humanity” of Hamas fighters and arguing Hamas deserved “kudos” for protecting civilians. In June 2026, the APA informed the House committee that it would no longer host division listservs and would instead provide an alternative online space to enhance its ability to monitor and remove content violating its policies.

    Clashes over “decolonial psychology” and journal publications

    The House report argues that APA leaders inflamed antisemitism by endorsing “decolonial psychology,” which the report characterizes as an academic framework that views Israel as an illegitimate settler-colonial state, justifies violent resistance, views Jews as white oppressors, and pathologizes Zionism as mental illness while demanding activism as part of clinical treatment.

    In 2025, American Psychologist published a special issue on decolonial psychology, an initiative championed by Bryant. One article, titled “Supervision as Decolonial Love: Toward a Transformative Training Process for Palestinian Community Health Workers,” referred to “Palestinian freedom fighters,” described Israel as a “settler colonial” state, and claimed “Zionist psychologies” legitimize an Israeli settler-colonial project.

    When the journal’s editor-in-chief later wrote to one of the authors, Devin Atallah, asking for references regarding the concept of “Zionist psychologies,” Atallah replied: “I do not have references for you on Zionist psychologies. I am also not in a place right now to be responding to general inquires [sic] I am at capacity.” Atallah suggested the editor educate himself about antizionism “on your own.”

    According to the House report, the decision to publish the “Decolonial Love” article prompted an editor for the journal’s May–June 2026 special issue on antisemitism to resign, stating the piece contained language that was “incendiary, politicized, and […] lacking the scholarly rigor we set out to uphold,” while alleging the APA was enforcing strict parameters on the antisemitism special issue that it did not apply elsewhere.

    The May–June 2026 special issue of American Psychologist on “Antisemitism and Psychology” was subsequently published. As an example of the scholarship included in that edition, one peer-reviewed study examined how political liberals and conservatives evaluate individuals who express prejudice. The study found that while political liberals generally disliked prejudiced speakers more than conservatives did, liberals evaluated speakers expressing antisemitism more positively when those remarks were justified by strong disapproval of Israel or human rights concerns, viewing the speakers as politically closer to themselves and less likely to be broadly bigoted.

    Jordan W. Moon of the University of Southampton, the study’s corresponding author, told PsyPost in October that the researchers found similar effects when speakers justified prejudice against Black or Chinese Americans by appealing to human rights abuses by African countries or China, describing the pattern as a general notion that prejudice is more acceptable when expressed by someone in one’s own group rather than something unique to antisemitism.

    Internal battles over resolutions and a Jewish association

    The House report also details internal disputes over APA resolutions. In February 2026, the APA’s Council of Representatives voted 127–37 to approve a revised Resolution on Antisemitism.

    The resolution states that the APA “condemns all antisemitic attitudes and actions,” pledges to take a leadership role in opposing antisemitism, recognizes the Holocaust, and notes that antisemitic violence increased following the October 7 attacks and Israel’s subsequent invasion of Gaza. It states there is broad agreement that it is antisemitic to hold Jews collectively responsible for Israel’s actions, require Jews to publicly condemn Israel, or deny Jews in Israel/Palestine the right to exist and flourish as Jews on the basis of legal equality. It also commits the APA to including information on antisemitism in its diversity training materials.

    However, the House committee criticized the measure as a “watered-down” resolution that “greenlights antisemitism,” stating that the Council of Representatives defied both the APA Board of Directors and a “Collaborative of Jewish Psychologists” formed to advise the board by voting on and passing a resolution that the Jewish advisory group never approved.

    The report specifically faulted the resolution for citing the Jerusalem Declaration on Antisemitism alongside the International Holocaust Remembrance Alliance (IHRA) definition, and for including a freestanding clause on the “weaponization of antisemitism.” That clause states that “the manipulative or bad faith invocation of accusations to silence legitimate criticism, scholarship, or activism” creates “significant adverse consequences” for Jews and non-Jews who oppose Israel’s actions and support Palestinian rights.

    Simultaneously, Jewish psychologists within the APA introduced a resolution to recognize a Jewish ethnic psychological association (EPA), on par with existing affiliated EPAs for Arab, Asian American, Native American, Latino, and Black psychologists. According to the House report, APA ethnic minority groups mobilized against the effort.

    The report quotes one of the main opponents of the resolution as arguing that “folks who have been conscripted into whiteness and benefitted from white privilege (whether they have collectively agreed or not) are seeking a seat and voice at the table with folks who have historically been marginalized.” Meanwhile, the APA’s Board for the Advancement of Psychology in the Public Interest (BAPPI) reported feedback from several groups that “many Jewish individuals (the majority of whom are white) do not face the same anti-Blackness, racism, white supremacy, coloniality, systemic or structural oppression as People of Color.”

    BAPPI also criticized the resolution for relying on information from the ADL and for citing Sigmund Freud, who escaped Nazi Austria in 1938 and had four sisters murdered in the Holocaust, and Albert Ellis, stating their contributions to psychology “may be influenced by factors such as white/economic/male privilege.”

    Additionally, the APA’s Committee on Ethnic Minority Affairs (CEMA) argued that recognizing a Jewish EPA without taking “urgent, unapologetic action on Palestine” and showing “explicit support for AMENA-Psy” would risk “reinforcing inequities and undermining solidarity across marginalized groups.”

    Reaction and next steps

    The House committee stated in its report that its findings will inform ongoing legislative efforts regarding discrimination by accrediting organizations.

    In an October 30 statement responding to the House report, the ADL said the committee’s findings confirmed its “gravest concerns” that antisemitism is embedded in the APA’s ranks and leadership. The ADL also noted that the APA had recently delayed for the second time in 2026 a vote on recognizing the Association of Jewish Psychologists as an EPA.

    “An organization devoted to the science of the mind has instead become a case study in how propaganda works, discarding facts in favor of political narratives and deepening the trauma of the Jewish psychologists among its members,” the ADL stated. “When a healing profession treats one group’s pain with such indifference, Jewish patients are right to wonder whether they will be met with compassion or with contempt.”

    The ADL called on the APA to publicly condemn antisemitism, strengthen its policies and bias incident reporting mechanisms, launch an independent investigation, require antisemitism training for all leadership and staff, and recognize the Association of Jewish Psychologists as an EPA.

    TITLE: Can watching sports make voters accept political defeats?

    URL: psypost.org/can-watching-sport

    Watching athletes and coaches gracefully accept defeat in televised sports can cause viewers to be more accepting of losses in political elections. By observing these routine displays of sportsmanship, voters become more likely to believe that an unfavorable election result was fair. These findings were published in the journal Political Behavior.

    A functioning democracy relies on losing candidates and their supporters accepting electoral defeats. Historically, the vast majority of the losing political party in the United States has accepted that their opponent won fairly. This pattern broke after the 2020 presidential election when a large portion of the losing party expressed skepticism about the voting process.

    Alex Tolkin, a political scientist at the University of Pennsylvania, wanted to understand what makes people willing to accept an undesired election outcome. He focused on the concept of legitimating rituals. These are public, repeated behaviors performed by competitors that signal a contest was conducted fairly.

    In politics, legitimating rituals include candidates shaking hands before a debate, giving a public concession speech after a loss, and attending the winner’s inauguration. In athletics, these rituals include post-game handshakes, press conferences where defeated coaches acknowledge their loss, and general displays of sportsmanship.

    According to social learning theory, people learn how to behave in novel situations by emulating the behavior of others. For someone to learn from a role model, they must observe the behavior, remember it, translate it to their own life, and feel motivated to copy it. Professional athletes and coaches serve as highly visible role models for millions of Americans.

    Sports leagues mandate many of these behaviors to protect the financial value of their games. Coaches and players are routinely fined if they publicly criticize referees or question the fairness of a match. American politics lacks a governing body that can force candidates to follow traditions like concession speeches.

    Since major political elections only happen every few years, Americans observe far more legitimating rituals in sports than they do in politics. To explore this dynamic in the real world, Tolkin analyzed data from a large panel study of 2,625 respondents. These participants were surveyed shortly before the 2020 presidential election and again in April 2021.

    This survey timeline allowed the researcher to track how individual attitudes shifted after the election results were finalized. The survey asked participants about their intended vote and how frequently they watched popular team sports like football, baseball, basketball, hockey, and soccer. It also measured their belief in the fairness of the election process.

    Participants rated the likelihood of various scenarios, such as ineligible people casting ballots, eligible voters being prevented from voting, or votes being counted inaccurately. Following the 2020 election, supporters of the winning candidate became more confident in the election process. Supporters of the losing candidate became less confident.

    Among the losing candidate’s supporters, watching sports moderated the decline in trust. Specifically, supporters of the losing candidate who frequently watched team sports reported a smaller drop in their belief that the election was fair compared to those who rarely watched sports. The researcher also compared sports viewership to political media consumption.

    While watching partisan television networks like Fox News was associated with a lower baseline belief in election fairness, watching sports was a stronger predictor of a positive shift in attitude after the defeat. The panel study established an association, but Tolkin wanted to test if observing legitimating rituals directly causes changes in political beliefs. He conducted a survey experiment with about 1,000 participants who identified as either Democrats or Republicans.

    The experiment was designed to manipulate the specific rituals participants watched. Participants were divided into different groups. Some read a summary of a basketball game and watched a video of the defeated coach giving a gracious post-game press conference.

    Others bypassed this sports-related content entirely. Next, all participants read about a fictional mayoral election in Jacksonville, Florida. They reviewed the platforms of two fictional candidates, selected their preferred choice, and wrote a brief explanation for their decision.

    All participants were then informed that their chosen candidate had lost in a close race. Following this disappointing news, some participants watched a political concession speech. They were told the speaker was the candidate they had just supported.

    To ensure the treatment was identical for everyone, the researcher used an edited video of a real political concession speech and deployed artificial intelligence voice-cloning software to dub in the appropriate fictional candidate’s name. Finally, participants answered a series of questions about the fairness of the fictional election procedures. The experiment revealed that participants who watched the defeated politician concede were more likely to believe the election was legitimate compared to those who did not see the political concession.

    Watching the sports concession speech also caused participants to view the political loss as more legitimate. This occurred even though the sports video was about a basketball game and made no mention of politics. The effect of the sports concession was roughly half as large as the effect of the political concession.

    These results demonstrated an additive benefit to observing legitimating rituals. Exposure to a message about being a good loser in a non-political context was sufficient to alter political attitudes. When participants were exposed to both sports and political rituals, their acceptance of the election results increased further.

    There are several caveats to consider regarding this research. The 2020 presidential election featured a losing candidate who refused to participate in traditional legitimating rituals like concession speeches. It is not entirely known if the observational patterns seen among sports viewers in 2020 will translate to more typical election cycles.

    The panel study relied on observational data. The analysis accounted for many demographic factors, but it remains possible that some unmeasured personality trait among frequent sports viewers influenced their reaction to the 2020 election. The experimental study provides the necessary evidence to show a direct causal link between watching rituals and accepting defeat.

    In the experiment, participants evaluated a fictional election involving candidates they had only just learned about. Their opinions were likely highly malleable. In real-world elections, partisan attitudes are deeply entrenched, and the effects of viewing a single sports concession speech might be small or short-lived.

    The study also measured sports viewership rather than emotional fandom, meaning the participants in the experiment were reacting to a sports coach they had no emotional connection to. The experimental results also revealed some differences based on political affiliation. Members of the Republican party in the study had lower overall belief in election legitimacy than members of the Democratic party.

    The effect of the sports concession speech on accepting the fictional election results was roughly half as large for Republicans as it was for Democrats.

    The study, “Good Sports or Sore Losers: Sports Fans and Perceptions of Election Legitimacy,” was authored by Alex Tolkin.

    TITLE: Neuroscientists propose a surprising new home for consciousness

    URL: psypost.org/neuroscientists-pr

    A new theoretical paper proposes that the most basic feeling of being a conscious self originates in the brainstem rather than the outer layers of the brain. By examining how the brain processes pain, anesthesia, and brain injuries, the authors suggest that raw sentience is computed in an ancient subcortical structure, located beneath the cortex, that acts as a gatekeeper for attention. The hypothesis, published in The Neuroscientist, challenges dominant models of the mind that place conscious awareness within the cerebral cortex.

    The brainstem is a stalk-like structure at the base of the brain that connects the upper brain to the spinal cord. Leading theories of consciousness locate it in the cerebral cortex, the wrinkled outer layer of the brain responsible for complex thought and language. In the authors’ view, these theories acknowledge the brainstem’s importance but treat it mainly as a power supply that keeps the cortex running. Yet a 2025 adversarial study of human brain activity failed to confirm key predictions of the two leading cortex-centered theories of consciousness, leaving open the question of how and where the brain generates subjective experience.

    To address this puzzle, the paper draws on a distinction from philosophy between two types of awareness: access consciousness and phenomenal consciousness. Access consciousness refers to the specific things a person is aware of at any moment, such as sights, sounds, or memories. Phenomenal consciousness, which the authors call raw sentience or the “me inside,” is the underlying feeling of existing as a conscious observer, a presence that remains completely intact even if a person closes their eyes and blocks their ears.

    Clinical and animal observations have repeatedly challenged the idea that the cortex creates this raw sentience. For instance, the author of a 2007 review on brain organization argued that children born without a cerebral cortex still display conscious awareness and emotional responses. Similarly, a 2015 clinical case study of a neurological patient found that a person with extensive damage to the brain areas widely believed to process pain could still fully feel and react to painful stimuli.

    Tiny disruptions in a specific part of the brainstem can have the opposite effect. In a 2001 rat experiment led by the new paper’s first author, delivering microscopic doses of an anesthetic drug directly into a specific pocket of the brainstem rapidly and reversibly switched off pain responses and other signs of consciousness. The new research, led by Marshall Devor of The Hebrew University of Jerusalem alongside colleague Mark Baron, brings these lines of evidence together into an evolutionary framework proposing that raw conscious feeling originated, and still resides, in the brainstem.

    Rather than conducting a single new laboratory experiment, the authors developed a hypothesis-generating theoretical synthesis drawing on clinical neurology, evolutionary biology, and their own laboratory’s prior animal experiments. They first evaluated clinical evidence from human patients undergoing awake brain surgery, patients experiencing epileptic seizures, and individuals with strokes or other brain lesions.

    In reviewing surgical data, the authors point out that applying mild electrical currents directly to the visual, auditory, or touch areas of an awake patient’s cerebral cortex reliably causes the patient to see flashes of light, hear sounds, or feel tingling. Yet stimulating the cortex almost never produces a feeling of pain. Even in the insula, a folded region tucked deep within the cortex whose rear portion is considered the strongest candidate for a cortical pain center, one study evoked pain at only 8 of 313 tested sites. Pain is also rarely reported as a warning sensation, or aura, at the start of epileptic seizures, even though seizures can involve almost any part of the cortex and often produce flashes of light, sounds, or smells.

    By contrast, direct electrical stimulation of subcortical pain pathways, including in the brainstem, reliably triggers feelings of pain in patients and animals. The authors also note that while extensive damage to the cerebral cortex can erase specific abilities, such as causing blindness or eliminating awareness of one side of the body, it does not cause a loss of raw consciousness or prevent a person from feeling pain. Small strokes or injuries in the upper brainstem, however, often plunge human patients into a coma.

    To pinpoint the exact location of this consciousness switch, Devor and Baron examined data from their laboratory’s rodent studies focusing on the mesopontine tegmentum, a region in the upper brainstem. The 2001 mapping study involved 828 microinjections in 182 rats. Only injections into one tiny node, now called the mesopontine tegmental anesthesia area, caused the animals to lose muscle tone, pain responses, and other signs of consciousness, and injections placed even slightly off target had no such effect. In later work, the team found that volumes of 10 nanoliters or less (a nanoliter is a billionth of a liter) could produce anesthesia within seconds.

    The researchers also examined what happened when they permanently destroyed cells in this area with a chemical toxin called ibotenic acid. When the damage was limited to a small patch, the rats did not fall into a coma. Instead, they woke up from surgery, resumed sleep-wake cycles with some insomnia, and became less sensitive to anesthetic drugs given through the bloodstream. From this, the authors conclude that the anesthesia area itself is not essential for generating raw consciousness.

    When they used larger amounts of the toxin to damage a wider area surrounding that spot, the outcome changed. Six rats that received these larger injections on target fell into an irreversible coma, whereas six rats whose injections landed nearby but off target woke up normally from surgery. Based on these results, the authors propose that the neural circuitry generating raw consciousness in rodents sits within a 3-by-4-millimeter zone of the mesopontine tegmentum that encloses the anesthesia area and overlaps with the parabrachial complex, a major hub for incoming pain signals.

    Drawing on these findings, the authors propose an evolutionary model for how consciousness works. When pain fibers in the skin or organs detect tissue damage from a threat like a predator’s bite, that signal already carries direct survival meaning, which the authors call Darwinian fitness valence, as soon as it enters the nervous system. In the authors’ reading, the ancient brainstem evolved sentience hundreds of millions of years ago in early vertebrates to translate these raw tissue-damage signals into the subjective feeling of pain, though they acknowledge there is currently no sure way to know whether fish or reptiles consciously feel pain.

    Other senses, such as vision and hearing, do not carry immediate survival meaning at the sensory organ; a pattern of light on the retina could be a harmless cloud or a charging rhinoceros. In the authors’ view, sophisticated analysis of sights and sounds requires the computing power of the mammalian cortex, which evolved roughly 300 million years after early vertebrates, though they acknowledge that animals without a cortex can detect threats by sight and sound at a more basic level. The authors suggest that rather than building a second consciousness system inside the new cortex, evolution wired the cortex down into the existing brainstem consciousness processor.

    In this model, the cortex operates like an unconscious supercomputer or a self-driving car, analyzing sights and sounds and sending a summary of their survival importance down to the brainstem. The brainstem circuit acts as an adjudicator, comparing the survival value of incoming signals against whatever the brain is currently focusing on. If a new signal is important enough, the brainstem sends a chemical or electrical signal back up to the cortex, “marking” that stream of information with conscious awareness while leaving routine tasks to run automatically in the background.

    These ideas fit with a human neuroimaging study that mapped an 18-node network linking the brainstem to higher brain regions to support wakefulness. That study charted arousal pathways rather than testing a theory of subjective experience, but it likewise placed brainstem circuitry at the foundation of human consciousness.

    There are some caveats to consider when evaluating this theory. Much of the brainstem evidence is also consistent with conventional, cortex-centered views, which already hold that the brainstem is needed to keep the cortex awake. Coma after brainstem damage or anesthetic injections does not, by itself, show that subjective experience is generated there. The theory’s distinctive support comes mainly from pain, the one sense the authors argue does not need the cortex.

    Even on the question of pain, it is difficult to completely rule out the possibility that when electrical stimulation or seizures in the human cortex occasionally trigger pain, the cortex itself is generating part of that feeling. The authors note that in some epilepsy patients, repeated stimulation of a specific site in the insula reliably triggers pain. Devor and Baron interpret such cases as signals spreading to brainstem pain pathways, but some researchers have argued that the posterior insula functions as a pain center in its own right.

    In addition, much of the evidence relies on translating findings between nonverbal animals and humans, or interpreting behavior in patients who cannot speak. In experiments with rats or observations of infants born without a cerebral cortex, researchers must infer conscious awareness and pain from physical reactions and vocalizations, which cannot definitively establish what an individual is subjectively experiencing on the inside. The coma lesion results pointing to the proposed consciousness zone also rest on just a dozen rats. The paper describes them only briefly, giving the animal counts in a figure caption, with no statistical tests or citation to a fuller earlier report.

    Finally, the paper presents a hypothesis rather than a definitive test. The authors have not yet identified the specific neurotransmitters or firing patterns the brainstem would use to “mark” cortical activity, and the model does not solve the philosophical “hard problem” of how biological cells produce a first-person feeling at all. They suggest that brainstem neurons might communicate by releasing chemicals that spread broadly through nearby tissue, much as dopamine does in parts of the brain, rather than through precise cell-to-cell connections. That kind of analog processing is not captured by today’s silicon computers, and the authors call for experiments to test these cellular mechanisms directly.

    The study, “Brainstem Theory of Consciousness,” was authored by Marshall Devor and Mark Baron.

    TITLE: New research reveals the psychological profile of reality dating television stars

    URL: psypost.org/the-psychological-

    People who participate in reality dating television programs tend to have higher levels of grandiose narcissism, derive much of their self-worth from physical appearance, and experience less anxiety about romantic rejection. A recent study evaluating the psychological profiles of people who appear on these shows suggests that these traits help them navigate the heavily scrutinized environment of televised romance. The findings were published in the journal Psychology of Popular Media.

    Reality television dating programs place individuals in highly visible, competitive environments where they seek romantic partners. These broadcasts have become a prominent part of popular entertainment over the past two decades. The format provides a controlled setting to observe how people form emotional bonds, conform to social norms, and express contemporary ideals of attraction.

    Researchers wanted to understand the psychological characteristics that distinguish the people who volunteer for these public displays of intimacy from the general public. Leonie Schlebusch, Florian Hutzler, and Sarah Schuster, researchers at the Paris-Lodron-University of Salzburg, led the investigation into how certain personality traits relate to participating in these programs.

    To build a psychological profile, the researchers focused on three main concepts: narcissism, attachment styles, and the sources of a person’s self-esteem. Narcissism is generally separated into two subcategories. Grandiose narcissism is characterized by self-assurance, a desire for dominance, an assertive communication style, and a strong need for admiration.

    Vulnerable narcissism shares a similar self-absorption but is marked by very different emotional expressions. Individuals with vulnerable narcissistic traits often display hypersensitivity, social insecurity, and persistent self-doubt.

    Attachment theory describes how people form emotional bonds and respond to intimacy. Originally developed to understand how infants interact with their caregivers, the theory also applies to adult romantic relationships. People with high attachment anxiety often fear rejection, worry about their partners’ feelings, and seek constant reassurance. People with high attachment avoidance tend to feel uncomfortable with emotional closeness and prefer to maintain distance in relationships.

    The final concept the researchers measured was contingent self-esteem. This refers to the specific areas in life that individuals rely on to feel good about themselves. Some people base their self-worth on internal values, academic competence, or family support. Others rely heavily on external factors like physical appearance, the approval of others, or outperforming peers in competitions.

    The researchers recruited 129 individuals to complete a series of online questionnaires. Fifty-eight of these individuals had participated in at least one reality dating program between 2017 and 2024. The remaining 71 participants served as a control group, meaning they had no experience on such shows. The participants in the television group were around 32 years old on average, while the control group averaged 27 years old.

    To find the television participants, the research team distributed flyers at events and venues associated with dating programs in Salzburg, Munich, and Cologne. The participants answered standardized questions designed to measure their levels of grandiose and vulnerable narcissism, their attachment anxiety and avoidance, and the specific factors they relied on for self-esteem.

    The research team then used statistical models to compare the responses between the two groups. They adjusted their calculations to account for demographic differences, such as age and education level, to isolate the effects of the psychological traits. In addition to the main questionnaires, the research team included open-ended follow-up questions exclusively for the dating program participants.

    These questions asked the participants to describe their motivations for appearing on the broadcasts and whether the experience altered their self-perception. A few individuals provided their answers through brief voice messages or video interviews rather than written text.

    The statistical analysis revealed that higher levels of grandiose narcissism strongly predicted whether someone was in the dating program group. For every standard unit increase in grandiose narcissism, the likelihood of a person being in the television group more than doubled.

    Vulnerable narcissism was not a statistically significant predictor of participation in the dating programs. The researchers suggest that the self-doubt and sensitivity to criticism associated with vulnerable narcissism might make highly public television environments unappealing. Grandiose narcissism, on the other hand, comes with greater emotional independence and a drive for self-promotion.

    The study also revealed that dating program participants had lower levels of attachment anxiety compared with the control group. Individuals who experience less fear of romantic rejection appear more willing to engage in televised dating. These environments require participants to handle emotional uncertainty and public visibility, which may deter those who require frequent reassurance from their partners.

    When looking at self-esteem, the researchers found that relying on physical appearance for self-worth was highly associated with dating program participation. Participants who tied their self-esteem to their looks were much more likely to have appeared on one of these shows. This aligns with the visual nature of the television programs, which often act as platforms to showcase physical attractiveness.

    Other external sources of self-esteem did not yield statistically significant differences between the two groups. Although the researchers initially thought that highly competitive people might be drawn to the format, self-worth based on competition was not a reliable predictor. Relying on the approval of others initially seemed to differ between the groups, but this difference disappeared once the researchers accounted for age and education.

    The responses to the qualitative follow-up questions provided more context for the statistical results. The most common reasons cited for joining a show were adventure, fun, and the desire to gain followers or visibility on social media platforms.

    Although some participants mentioned hoping to meet a romantic partner, stating “The aim was actually to get to know someone,” many viewed love as a potential side effect rather than their primary goal. Other participants were more direct about their intentions, explicitly stating their goal was to “Generate reach on Instagram” or simply declaring “Let’s go on an adventure.”

    When asked whether appearing on television altered their self-perception, the majority reported no lasting psychological changes. Many expressed sentiments like “I’m the same person I was before.” Among those who did report a shift, some noted an increase in self-confidence or a greater sense of emotional maturity.

    A few participants reported negative effects on their self-esteem, which they generally attributed to public criticism from viewers. One individual explained, “My self-esteem has suffered a lot from people who don’t know me.”

    The study relies on a modest number of participants, and the control group differed demographically from the television participants. The individuals in the control group were generally younger, more highly educated, and more likely to be students. Although the researchers adjusted their statistical models to account for these differences, variations in life stage and social environment may still influence the results.

    The measurement tool used to assess vulnerable narcissism in this study had low internal reliability. This means the questions may not have captured the trait as consistently as desired. This measurement issue could obscure a true relationship between vulnerable narcissism and television appearances. Future investigations could use different assessment tools and recruit larger groups of individuals with diverse educational backgrounds.

    The study, “Narcissism on the Beach? Attachment Style, Personality, and Self-Esteem Contingencies of Dating-Show Participants,” was authored by Leonie Schlebusch, Florian Hutzler, and Sarah Schuster.

    Scientists propose that the brain’s mysterious cross-wiring, which connects each hemisphere to the opposite side of the body, may have originated more than 500 million years ago in the visual systems of ancient fish. Rather than evolving for a specific advantage, this unusual arrangement may simply be a legacy of evolution building new brain circuits on an ancient foundation.

    TITLE: One month of time-restricted eating linked to a nine-month drop in estimated brain age in new study

    URL: psypost.org/one-month-of-time-

    Men with metabolic syndrome who limited their meals to an eight-hour window between morning and mid-afternoon for a month scored higher on a memory test afterward and had slightly younger brain age estimates on MRI scans, according to a small study published in Frontiers in Aging. The men also lost weight and showed improvements in blood sugar and insulin sensitivity, along with increases in gray matter volume in several deep brain regions, including two tied to memory.

    Metabolic syndrome is a cluster of physiological conditions that occur together and raise the risk of heart disease, stroke, type 2 diabetes, and cognitive decline. A clinical diagnosis is made when a person has at least three of five risk factors: excess abdominal fat measured by a large waist circumference, high blood triglycerides (a type of fat circulating in the bloodstream), low levels of high-density lipoprotein (HDL) cholesterol, elevated blood pressure, and high fasting blood sugar. Beyond its effects on cardiovascular health, metabolic syndrome is linked to accelerated brain aging and memory loss, with epidemiological research indicating that men with the condition face a higher risk of cognitive decline than women of the same age.

    The authors note that metabolic dysfunction can wear down the brain through several pathways, including chronic inflammation, reduced blood flow in small cerebral vessels, and central insulin resistance, a state in which brain cells become less responsive to the hormone insulin and struggle to maintain the neural connections needed to form memories. Over time, this stress contributes to structural brain aging, which involves a gradual loss of gray matter, the tissue rich in nerve cell bodies that processes information and supports memory.

    Scientists can estimate this physical wear and tear by feeding structural MRI scans into machine-learning algorithms trained on thousands of healthy brains to predict a person’s brain age. The difference between this MRI-predicted age and a person’s actual chronological age is called the brain age gap, where a positive gap indicates that a brain looks older than expected for a person’s age.

    Prior neuroimaging work has linked excess weight and metabolic trouble to an older-appearing brain. For instance, a neuroimaging study of middle-aged and older adults found that overweight individuals had widespread reductions in cerebral white matter volume compared to lean peers, corresponding to an estimated 10-year increase in brain age even though their scores on cognitive tests did not differ. More recently, a 2024 neuroimaging study of overweight and obese adults reported that people with poorer metabolic profiles, marked by insulin resistance and unhealthy blood lipid levels, had larger brain age gaps than metabolically healthier individuals.

    One dietary approach designed to counter metabolic dysfunction is early time-restricted eating, a form of intermittent fasting in which a person consumes all daily meals within a fixed window from morning to mid-afternoon and fasts for the rest of the day without required calorie counting. Aligning food intake with the body’s daytime circadian rhythms has shown metabolic benefits in humans; a 2022 randomized clinical trial of adults with obesity, all of whom were also cutting calories, found that those who ate only between 7 a.m. and 3 p.m. lost more weight and saw a larger drop in diastolic blood pressure than those eating over 12 or more hours.

    In laboratory animals, a 2024 study in male mice found that restricting daily food access restored metabolic rhythms and prevented memory impairments caused by a high-fat, high-sugar diet independently of body fat levels, an effect linked to thyroid hormone signaling in the hippocampus.

    Building on this work, Yue Qin of Xi’an Daxing Hospital Affiliated to Yan’an University, along with senior authors Yarong Wang of The First Affiliated Hospital of Xi’an Jiaotong University and Ying Xing of Xi’an Daxing Hospital, examined whether a one-month early time-restricted eating intervention would be associated with a smaller brain age gap and better memory performance in men with metabolic syndrome.

    The researchers recruited 23 men between the ages of 25 and 55 (with an average age of about 35 years and an average of about 15.5 years of education) who met the clinical criteria for metabolic syndrome. All participants had maintained a stable body weight, defined as a change of less than 10 percent, during the three months before enrollment, and any men taking medications for blood pressure, blood sugar, or cholesterol were required to keep their dosages constant throughout the study. The team excluded night-shift workers and individuals with tobacco or alcohol addiction, neurological disorders, severe psychiatric conditions, or a history of weight-loss surgery or appetite-altering medications.

    Before starting the dietary intervention, all 23 men maintained their regular diet and exercise routines for one month to establish a stable baseline. For the following month, they were instructed to consume all of their food within an eight-hour window between 8 a.m. and 4 p.m. every day, without any restrictions on the types or quantities of food eaten during those hours, and to drink only plain water during the 16-hour fasting window from 4 p.m. to 8 a.m. To verify compliance during fasting hours, each man wore a continuous glucose monitor that sent real-time blood sugar readings to an endocrinologist via a mobile app, allowing the medical team to contact a participant immediately if an unauthorized meal caused a blood sugar spike. Participants also uploaded daily meal photos to an individual group chat with study clinicians.

    At the start of the intervention and again after one month, the researchers measured each participant’s weight, body mass index (BMI), and overnight fasting blood levels of triglycerides, cholesterol, glucose, and insulin, which were used to calculate mathematical indices of insulin resistance and insulin sensitivity. Memory performance was evaluated using the validated Chinese version of the Rey Auditory Verbal Learning Test, a word-list learning assessment that measures immediate recall (remembering words right after hearing them across repeated trials), delayed recall (remembering the words after a waiting period), and interference recall (remembering a second, distracting word list).

    Each man also underwent structural MRI brain scans at both time points. The team used a machine-learning tool called brainageR, trained on scans from 3,477 healthy adults, to calculate each participant’s estimated brain age from gray matter maps, and they applied a technique called voxel-based morphometry to divide the brain into tiny three-dimensional cubes and track localized gray matter volume changes while controlling for total head size.

    All 23 men completed the program. On average, they lost about 4.4 kilograms (roughly 9.6 pounds), and their BMI fell from about 31.4 to 30. Fasting triglycerides dropped by about 29% and fasting blood sugar by about 10%, while fasting insulin and insulin resistance also declined and insulin sensitivity improved. Changes in total, HDL, and LDL cholesterol were not statistically significant.

    On the word-list test, average immediate recall scores rose by about 19%, from roughly 45 to 54 points, and delayed recall rose by a similar margin, from about 9.4 to 11.3 points. The change in interference recall was not statistically significant. At the start, the men’s estimated brain ages averaged about 2.8 years older than their actual ages. After the month of early eating, that gap had shrunk to about 2.0 years, a reduction of roughly nine months.

    When the researchers examined specific brain structures using voxel-based morphometry, they found that gray matter volume increased in four regions on the left side of the brain: the left thalamus, the left hippocampus, the left substantia nigra, and the left red nucleus. The hippocampus and thalamus are interconnected deep-brain structures that form a circuit for encoding and retrieving memories, while the substantia nigra is a midbrain region involved in movement and reward processing and the red nucleus is a midbrain structure involved in motor coordination.

    After applying a statistical correction for multiple comparisons, gray matter changes in the hippocampus, substantia nigra, and red nucleus were not significantly correlated with changes in memory scores, but volume changes in the left thalamus showed an inverse correlation with changes in immediate recall scores (r = -0.512). Although both left thalamic gray matter volume and immediate recall increased across the group overall, individual men who had smaller volume increases in the left thalamus tended to show larger gains in immediate word recall.

    The authors suggest that this inverse relationship between thalamic volume growth and immediate recall gains may reflect the fact that physical brain remodeling and behavioral improvements do not always unfold at the same pace. Drawing on prior neuroimaging studies of skill learning, they propose that gray matter may initially expand as part of an early adaptive reorganization before memory performance catches up. They also note that the thalamus is composed of multiple specialized sub-regions that support different phases of memory, which may adapt on different timelines during a short intervention.

    As for how the eating schedule related to brain aging overall, the researchers hypothesize that the diet may work by improving cerebral blood flow, stimulating cellular cleanup processes known as autophagy, and boosting levels of brain-derived neurotrophic factor, a protein that supports neural plasticity, though these biological pathways were not directly measured in the study.

    “I think this is an interesting study that points to a promising direction in understanding the relationship between food and brain health,” said Mei Peng, an associate professor of psychology at the University of Otago in New Zealand and director of the Sensory Neuroscience and Nutrition Lab, who was not involved in the study. “It adds to the mixed evidence on fasting and cognitive performance.”

    “There is also an intriguing parallel with exercise adapting to manageable physiological challenges can benefit the brain,” Peng told PsyPost. “So a little bit ‘stressful’ body might be good for the mind. For the public, the main takeaway is that the relationship between diet and brain health may involve not only what is on our plates, but also when and how we eat.”

    The findings fit with a clinical trial of older adults with obesity and insulin resistance that tested a 5:2 intermittent fasting diet and found reductions in MRI-estimated brain age along with memory gains. In that trial, however, a standard healthy diet also reduced brain age estimates, suggesting the changes may not be unique to fasting. The results also echo a neuroimaging study of patients with severe obesity, in which brain age estimates fell in the two years after weight-loss surgery. Memory gains have also been observed in an experimental study in mouse models of Alzheimer’s disease that restricted daily feeding windows.

    “I would say the human evidence is still mixed,” Peng said. She noted that a 2025 trial of older adults with mild cognitive impairment saw some cognitive test scores improve.

    “In our own randomized study of healthy adult women, however, four weeks of time-restricted eating did not produce a clear benefit for working memory or attention compared with usual eating,” she continued. “One possibility is that people with existing metabolic or cognitive difficulties have more scope to benefit, but that remains to be tested. This new study adds an interesting brain-imaging perspective to that question.”

    There are a few things to keep in mind when interpreting these findings. Most notably, the researchers did not measure how many calories the participants ate before or during the one-month intervention. When people restrict their eating to an eight-hour daytime window, they often naturally eat less food, which is consistent with the average weight loss of more than four kilograms over the month. As the authors point out, without tracking daily energy intake, the study cannot separate the specific benefits of aligning meal timing with circadian rhythms from the effects of spontaneous calorie restriction and weight loss.

    “I see this as an encouraging early signal,” Peng said. “The main uncertainty is that there was no comparison group, so we cannot tell how much of the improvement was due to the eating schedule.” Without an untreated control group of men with metabolic syndrome who continued their usual eating habits, it is not possible to rule out other influences on the results, such as the daily medical supervision and encouragement in the clinician chat groups or practice effects from taking the same verbal memory test twice within a single month.

    “‘Brain age’ can sound more literal than it is,” Peng noted. “Here, it is an estimate generated from patterns in MRI scans. A lower estimate does not necessarily mean someone’s brain has become biologically younger, and this study does not show that fasting prevents dementia. It also cannot tell us whether healthy people would experience the same changes.”

    The paper also does not report whether the men whose brain age estimates dropped most were the same ones whose memory improved most, although its methods describe testing that link. It also contains several reporting inconsistencies, including a statistic for the main brain age result that does not match its reported level of statistical significance.

    In addition, the trial involved a small sample of 23 young and middle-aged men followed for just four weeks, leaving it uncertain whether the findings would generalize to women or older adults. The authors note that future studies should include larger cohorts with female participants, systematically track daily caloric intake to distinguish meal-timing effects from calorie reduction, and follow participants over longer periods to see whether the changes in brain age estimates and memory are lasting.

    “I would particularly like to see studies comparing time-restricted eating with calorie restriction, to help distinguish the effects of when we eat from how much we eat,” Peng added. “It would also be valuable to follow people’s usual eating windows and habits over time and examine how these relate to brain health. Asking someone to change their eating schedule can also change what they eat, their sleep or their other daily routines, making it difficult to identify what drives any benefit. Observational studies cannot establish cause and effect on their own, but alongside controlled trials, they could help us understand whether these findings translate into everyday life.”

    The study, “One-month early time-restricted eating mitigates brain aging and enhances memory in males with metabolic syndrome: an MRI structural study,” was authored by Yue Qin, Xiaoshi Li, Lei Wang, FengLin Shuang, Xin Jin, Tingting Qu, Yuying Wang, Yunbing Wu, Juan Tian, Yifan Qian, Qianqian Lv, Zirui Wang, Yarong Wang, and Ying Xing.

    TITLE: Social media rewards politicians for negative partisan attacks, study finds

    URL: psypost.org/social-media-rewar

    Members of the United States Congress have become increasingly partisan and negative in their online communications over the last decade. A massive study evaluating millions of social media posts and emails found that politicians receive disproportionately high engagement when they attack political opponents rather than sharing legislative accomplishments. The findings were published in the American Political Science Review.

    Political representatives have long used a variety of strategies to connect with their constituents and secure reelection. In the 1970s, political scientists established that legislator communications traditionally fell into a few universal goals, such as promoting a personal brand, claiming credit for legislative accomplishments, or taking stances on issues voters care about. For decades, politicians relied on mailers, televised press conferences, and local newspapers to achieve these goals.

    The rise of the internet fundamentally altered this dynamic. Digital platforms allowed elected officials to bypass traditional news outlets and broadcast their messages directly to a national audience. This technological shift occurred alongside a growing ideological divide within the American electorate.

    Michael Kistner, a political scientist at the University of Houston, and a team of colleagues wanted to understand how this shift to digital platforms altered the way elected officials talk to the public. The research team noted that previous investigations often focused on short timeframes or single platforms. Those limited scopes made it difficult to spot long-term trends or compare different types of audiences.

    To build a more comprehensive picture, the researchers gathered a massive dataset of online communications from members of Congress spanning from 2009 to 2022. They collected approximately 4.7 million posts from Twitter, 2.4 million posts from Facebook, and 184,000 official email newsletters. The dataset encompassed nearly the entire era of widespread social media use in politics.

    To analyze this vast amount of text, the team utilized computational language models to categorize messages based on their intended purpose. The researchers trained these models on a subset of messages manually reviewed by human experts. The models then evaluated the remaining millions of sentences to determine if a politician was advertising an event, claiming credit for a policy, assisting constituents, or engaging in negative partisan attacks.

    The system also analyzed the vocabulary used in each message to scale the text on a continuous partisan spectrum. Extreme partisan speech often features vocabulary used almost exclusively by one political party, while moderate speech employs language shared by both sides. A computer algorithm assigned each post a partisanship score based on how strongly its language identified the speaker’s political affiliation.

    Before running their main analysis, the researchers validated their computer models against other common measures of political behavior. They compared the language scores to members’ positions based on roll call votes, how often they voted in line with the president’s stated preferences, how they raised campaign funds, and the issues they highlighted on their official websites. The text-based scores aligned well with these established benchmarks. Members who sponsored bipartisan bills in real life tended to use more bipartisan language online, and those who frequently mentioned local towns in floor speeches were more likely to post about constituent services.

    The researchers then mapped out the rhetorical trends across the 14-year period. The analysis revealed a steady, substantial increase in partisan polarization in congressional rhetoric across all three communication platforms between 2011 and 2022. The language used by Republicans and Democrats diverged markedly as the decade progressed. Topics of conversation shifted away from routine governance and toward partisan conflict.

    While the partisanship of Democratic speech remained largely flat over the decade, with no statistically significant trend, Republican rhetoric shifted heavily toward the extremes. The data showed that Democrats increasingly focused their messaging on progressive priorities, using words related to climate, democracy, and infrastructure. Republicans pivoted toward immigration and combative rhetoric, with frequent references to the border and the opposing party.

    In addition to becoming more ideologically separated, the specific types of messages politicians prioritized shifted over time. The portion of communications dedicated to negative partisan attacks grew rapidly. Negative attacks represented about five to ten percent of messages in the early years of the study but increased to nearly twenty percent by the end of 2022. Position-taking, where a politician simply states their stance on a controversial issue, also grew to dominate the digital conversation.

    At the same time, routine governance topics became less prominent overall. Messages about delivering federal funding for a local district or offering constituent assistance failed to keep pace with the rise in partisan attacks. The researchers noted that the sharpest increase in negative partisan messaging by Democrats occurred after the 2016 presidential election. Republicans showed a similar spike in negative messaging following the 2020 election.

    To explore a potential incentive driving these rhetorical shifts, the research team looked at how the public responded to different types of messages on Facebook and Twitter. Social media platforms provide immediate, quantifiable feedback that politicians and their staff use to evaluate their communication strategies. The research team tracked engagement metrics such as likes, shares, retweets, and comments for each post in their database.

    The researchers then compared the engagement levels of negative or highly partisan posts against those focused on bipartisan cooperation or local constituent services. Negative partisan attacks generated vastly more attention than any other type of communication. On Twitter, negative attacks received 60 percent more likes, 80 percent more retweets, and 79 percent more replies than an average post by the same politician. Facebook yielded similar results, with partisan attacks gathering 86 percent more shares and 93 percent more comments than routine updates.

    Conversely, messages about bipartisan collaboration or local district services received less engagement than the typical social media post. Credit claiming, which involves a politician taking responsibility for a positive government action, also failed to attract high levels of online interaction. The data suggests that social media algorithms and user behaviors heavily reward hostility and ideological extremity over traditional legislative work.

    A casual reader might assume that the high engagement for negative posts reflects the genuine desires of the broader electorate. The researchers caution against this interpretation, pointing to evidence that the messaging that attracts engagement online differs from the messaging voters say they prefer.

    In separate survey data, researchers regularly find that most voters prefer representatives who focus on legislative achievements rather than partisan bickering. Politicians may be falling victim to a “social media feedback mirage,” mistaking digital likes and shares from a polarized online audience for true political support. When elected officials rely on these engagement metrics to evaluate their performance, they risk becoming trapped in a cycle of escalating negativity that fails to serve the broader public.

    The study’s data concludes in 2022, which means it does not capture the recent rise of alternative platforms like Bluesky and Truth Social. These newer networks cater to specific ideological groups and may fragment political audiences further in the future. However, the researchers noted that the vast majority of elected officials still maintain active, primary profiles on Facebook and X, the platform formerly known as Twitter. Future research will need to examine whether politicians adapt their strategies as these digital environments evolve and as visual platforms like YouTube and Instagram gain prominence.

    The study, “Measuring Partisanship and Representation in Online Congressional Communications,” was authored by Michael Kistner, Michael Heseltine, Robert Alvarez, Maya Fitch, Lucas Lothamer, and Elizabeth Simas.

    TITLE: Massive study upends our understanding of the psychology of collectivism

    URL: psypost.org/massive-study-upen

    A global study of more than 12,000 people across 100 cultures suggests that standard psychology surveys have struggled to measure collectivism because they confuse obligation to close family and friends with general friendliness toward everyone. By redefining collectivism as “responsibilism,” which focuses on binding duties in specific close relationships rather than warm feelings toward people in general, researchers identified large cultural differences between East Asian and Western societies that earlier scales missed. The findings, published in Nature Human Behaviour, also indicate that this duty-based measure aligns closely with real-world behaviors ranging from multigenerational living arrangements to blood donation patterns.

    In psychology and across the social sciences, collectivism refers to a cultural system in which people view themselves as interconnected with others and prioritize social relationships and group obligations over personal desires. It is commonly contrasted with individualism, a cultural orientation that emphasizes personal independence, autonomy, and looking after oneself. When a wave of self-report questionnaires appeared in the 1990s, scholars of East Asia in fields such as history, anthropology, and political science widely expected East Asian societies to score higher on collectivism than Western nations.

    Once those questionnaires were administered around the world, however, the results frequently contradicted expert expectations. Earlier reviews of the literature, including an analysis of 76 separate studies, found that standard collectivism surveys were no better than a coin flip at detecting expected differences between East Asian and Western participants, and one meta-analysis even concluded that Japan was less collectivistic than the United States. Some researchers argued that the popular view of Japanese collectivism was simply an inaccurate stereotype. Many others concluded that self-report surveys were inherently flawed for cross-cultural comparisons, suggesting that respondents in different countries use rating scales differently or interpret abstract words like “independence” in incompatible ways.

    The new research, led by Thomas Talhelm, the Robert B. Cialdini Endowed Professor of Social Influence at Arizona State University, alongside Liuqing Wei of Hubei University and Alexander S. English of Wenzhou-Kean University, proposes that the flaw lies in how psychologists define collectivism rather than in the survey method itself. According to the authors, classic questionnaires mixed together two opposing ideas: “warm fuzzy” collectivism and what the team calls “responsibilism.” Warm fuzzy collectivism describes feeling positive emotions toward people in general, enjoying cooperation, and extending friendliness broadly without drawing a sharp line between close family and strangers.

    “Researchers created scales to measure collectivism, but they kept finding weird results,” Talhelm told PsyPost. “Were places like the U.S. and U.K. really more collectivistic than cultures like China and Japan? Researchers came up with all sorts of sophisticated methodological explanations, but when I looked at the actual survey items, it seemed clear to me. There were ‘warm fuzzy’ items right there in plain sight, and collectivism isn’t about good feelings!”

    Responsibilism, by contrast, sets aside warm feelings and focuses on behavioral duties, social roles, and binding obligations within specific, close relationships, paired with weaker obligations toward strangers or acquaintances. In the new study, Talhelm and his colleagues argue that when collectivism scales include warm fuzzy statements like “To me, pleasure is spending time with others,” Western respondents tend to agree more than East Asian respondents, canceling out the items that actually measure interpersonal duty.

    To test whether experts still conflate generalized warmth with collectivism, the researchers first surveyed 40 scholars who had published articles in the Journal of Cross-Cultural Psychology. The scholars were shown 14 warm fuzzy statements and one duty-based statement from classic collectivism scales and were asked to guess whether survey respondents agreed with each item more in East Asia, more in the United States, or about equally. The researchers then compared the scholars’ predictions against actual survey responses from 195 participants in China and the United States.

    Many of the scholars held warm fuzzy expectations that the survey data did not bear out. For example, 83% predicted that people in China would agree more with the statement “My relationships with others are more important than my own accomplishments,” but American participants agreed more. Similarly, 78% guessed that Americans would agree more with the competitive statement “Winning is everything,” when Chinese participants did.

    Across all 14 warm fuzzy items, the most popular prediction matched the actual data only twice. The scholars’ intuitions about duty were far more accurate: 95% correctly predicted that East Asian participants would agree more with “We should keep our aging parents with us at home.”

    Next, the authors built a 14-item responsibilism scale, plus a five-item short version that closely tracked the full scale. The questionnaire was designed around concrete, everyday scenarios and specific relationships rather than vague references to “others” or “groups.” The team adapted three items from a widely used 1995 collectivism scale and wrote new items that contrasted obligations to close friends and relatives with openness toward strangers or unfamiliar group members.

    In one scenario, participants imagined getting a 60% grade on a midterm exam and being harshly told by a good friend, “It’s your fault. You need to study harder,” then rated whether they would look for more supportive friends. In another scenario, participants rated whether they would feel comfortable telling an unfamiliar coworker from a different department about a major sales account they were developing. The researchers expected people in responsibilistic cultures to stand by the critical friend, since close relationships are meant to last even when they are unpleasant. They also expected those people to be warier of sharing with the unfamiliar coworker, since belonging to the same company is not enough to earn trust.

    One question produced a result that challenged Talhelm’s own cultural assumptions. “I think one of the most interesting findings that cut against my expectations was a question about lending money to a friend who asked for it,” Talhelm recalled. “I expected people in responsibilistic cultures to say ‘yes,’ but they were actually less likely to agree. So I followed up with people from responsibilistic cultures.”

    “They had plenty of stories to tell me about giving money to friends or family, but they usually didn’t involve directly asking for it,” he continued. “How American of me! I assumed people would ask directly. But the stories people told me clued me in that that’s often not how it plays out.”

    The researchers recruited 16,237 adults, mostly college students, so that participants would be similar in age, education, and stage of life across countries. After removing people who failed data-quality checks or were not born and raised in the local culture, the final sample included 12,247 participants in 100 cultures that together cover 90% of the world’s population. Country scores were nearly identical when everyone was included.

    To keep English idioms from distorting the questions, the team wrote the scale in English and Chinese at the same time, and local collaborators then translated it into 45 languages. The main study was not preregistered, but the materials, data, and analysis code are publicly available on the Open Science Framework. The team also shares its global map, data, and survey on a responsibilism website.

    The new scale picked up large differences between East Asian and Western cultures, the kind of gap that earlier scales had repeatedly failed to find. Regions in Africa, the Middle East, and several parts of Asia scored highest, Latin America and the Caribbean fell in the middle, and North America, Europe, and Australia scored lowest.

    “Differences between how people answer these questions in Western cultures versus cultures in East Asia are over a full standard deviation different!” Talhelm explained. “The effect size is in the same ballpark as the difference in height between men and women. Now, that still leaves room for exceptional casesa woman taller than most men and an American who scores more responsibilistic than the average in China. But these differences are large enough that people should notice them when they travel across cultures.”

    These differences held up when the researchers accounted for participants’ age, gender, and socioeconomic status. To rule out translation as the cause, the team also gave the English version to participants in Hong Kong, where English is widely used in education, and still found a large gap with the United States. An independent team’s preregistered replication likewise found that participants in Singapore scored higher than participants at Western sites.

    “If people can walk away with the understanding that there are these two competing visions of collectivismwarm fuzzy versus responsibilism, I’ll be happy,” Talhelm said. “Remember that the warm fuzzies are NOT good descriptions of cultures that people think of as collectivistic, like China, Turkey, or Ghana. But responsibilism (concrete behavioral duties in close relationships) does describe these cultures well.”

    Scores on the new scale had little relationship with scores on eight of the most widely cited older collectivism scales. On average, the relationship was slightly negative, suggesting that responsibilism captures something different. One of the strongest overlaps was with part of the 1995 scale that supplied three of the new items.

    The researchers then checked how well the new scale and the five most-cited older scales matched real-world indicators of close family ties and treatment of strangers, drawn from census data, field experiments, and other international datasets. Responsibilism scores lined up strongly with these indicators. The older scales did not, and on average they pointed slightly in the wrong direction: countries scoring higher on some of them actually had weaker clan traditions and fewer people living with extended family.

    Countries scoring higher on responsibilism tended to score higher on census-based measures of family life, such as household size and the ratio of marriages to divorces, and on an index of extended-family and clan traditions. People in these countries were more likely to agree that a friend has the right to expect them to lie in court on the friend’s behalf. They also donated more blood to family members but less to strangers, and returned fewer lost wallets in field experiments.

    United Nations diplomats from more responsibilistic countries also ran up more unpaid New York City parking tickets while protected by diplomatic immunity. That behavior’s costs fall on strangers and the public system rather than on family or friends. Nearly all of these links held after accounting for national wealth; the exception was blood donations to family.

    This emphasis on binding interpersonal obligations aligns with an earlier study of relationship scenarios in China and the United States, which found that Chinese participants were less likely than Americans to feel and directly express gratitude toward close others, a pattern its authors linked to collectivist norms that treat helping a close friend or relative as an expected duty rather than a favor. That earlier work examined reactions to specific relational situations in two countries rather than applying a broad cross-cultural scale, but both studies suggest that East Asian relationship norms prioritize fulfilling duties over expressing warm sentiments.

    Beyond family life, more responsibilistic countries tended to have more perceived government corruption, which the authors suggest fits with putting personal connections ahead of impersonal rules. They also tended to score lower on measures of democracy, innovation, and economic freedom, and had fewer deaths from COVID-19 and from drug use disorders. These links held after accounting for national wealth. Links with holistic thinking (a style that focuses on context and relationships) and with less migrant-friendly policies did not survive once wealth and the number of statistical tests were taken into account.

    In exploratory analyses, responsibilism tended to be higher in places with a history of more infectious disease and in places where more farmland is devoted to rice. Earlier research by Talhelm and colleagues suggests that rice farming required close coordination among families and neighbors. Wealthier countries, and those with a history of livestock herding, a more independent way of making a living, tended to score lower.

    Because the scale asks people about their own choices rather than asking them to rate their country, it can also detect differences between people in the same country. In the United States, Southerners scored slightly higher than Northerners, and Americans with Asian or Latin American heritage scored higher than European Americans. Students at the University of Illinois Chicago, which enrolls many first-generation college students, also scored higher than students at highly selective universities.

    Across the full dataset, people who placed themselves higher on a social class ladder scored slightly lower on responsibilism, while people who described themselves as more socially conservative scored somewhat higher. The older scales, on average, showed almost no link with either social class or politics.

    “I think the responsibilism-vs-warm-fuzzy distinction is a useful way to see the world, even if you never leave your hometown,” Talhelm noted. “You can see the differences in other places too, like between working class and middle class, as well as liberal politics (warm fuzzy) and conservative politics (responsibilistic).”

    In the authors’ reading, warm fuzzy collectivism and responsibilism represent two contrasting ways of approaching human relationships rather than a rejection of social ties altogether. They suggest that in societies with fewer binding obligations to family and close circles, people have more freedom to choose relationships based on personal enjoyment and to leave unsatisfying friendships, which may explain why respondents in individualistic cultures agree more with warm fuzzy statements.

    “One pushback I get is along the lines of ‘What about socialism? That’s the real collectivism!'” Talhelm said. “Socialism (at least as an ideal) is the opposite of responsibilism. Responsibilism is about prioritizing close relationships over distant relationships. Socialism is all about big groups, ‘the many,’ the collective.”

    “Some people want to say that’s the real collectivism, and that’s OK with me,” Talhelm continued. “As long as people understand that responsibilism is different, and responsibilism is a more accurate description of cultures that people typically describe as collectivistic, then we’re on the same page.”

    As with all research, there are some caveats to consider when interpreting these findings. The links with real-world behavior compare national averages drawn from other datasets, so they describe countries rather than individuals; the diplomats and wallet finders were not the study’s participants. Because these cross-cultural comparisons and links to societal indicators such as corruption, innovation, and public health are observational, they also cannot establish that responsibilism directly causes those societal outcomes. In addition, the researchers relied primarily on university students in the 100 cultures to keep the samples demographically similar across countries, meaning the scores reflect a younger, more educated segment of each society rather than nationally representative populations.

    There are also boundaries to what the new scale measures. The authors designed the 14-item questionnaire specifically to capture duties in close relationships versus generalized warmth toward strangers, which leaves out other potential facets of collectivism, such as how much people adjust their behavior to fit changing social contexts. The study also does not settle ongoing debates over whether individualism and collectivism represent opposite ends of a single spectrum or separate dimensions that can coexist in the same person or culture. Future studies can test whether adding other behavioral dimensions improves the scale and can develop items simultaneously in languages with features like grammatical gender, going beyond the English and Chinese drafts used here.

    “We have a fun follow-up right now showing people across cultures different messages to try to encourage people to donate money to climate change,” Talhelm said. “The idea is that we can make these messages more impactful if we fit them to the cultureeither warm fuzzy messages or duty-bound responsibilistic messages. So far, we’re finding that people in cultures like the U.S. and Australia are more willing to donate if they see a warm fuzzy message that emphasizes caring about all people around the world.”

    “In responsibilistic cultures, that message does not help,” he concluded. “The bottom line is that we can be more effective at communicating if we understand some basics of culture.”

    The study, “Defining collectivism as duties in relationships rather than generalized warmth improves predictive validity in 100 cultures,” was authored by Thomas Talhelm, Liuqing Wei, Rui Sun, Danila Medvedev, Álvaro San Martin, May Helmy, Adil Samekin, Alejandra Zaragoza Scherman, Alexander S. English, and The Responsibilism Collaboration Team.

    TITLE: Kids who eat more ultra-processed foods show a troubling brain response

    URL: sciencedaily.com/releases/2026

    A new study suggests that ultra-processed foods may influence children's developing brains in ways that encourage weight gain. Researchers from USC studied 46 children ages 7 to 10 and found that those who ate more ultra-processed foods showed stronger activity in the brain's reward system when viewing tempting foods like cookies and French fries. These heightened brain responses were linked to greater increases in body fat and body mass index (BMI) one year later, suggesting that the brain's sensitivity to food cues may help explain why ultra-processed diets are associated with obesity.

    TITLE: Self-perceived masculinity and femininity predict political views better than biological sex

    URL: psypost.org/how-self-perceived

    A recent paper published in Politics and the Life Sciences outlines how internal perceptions of masculinity and femininity strongly predict political engagement and ideological leanings. Moving beyond traditional male and female demographic categories, the authors show that a person’s continuous gender identity can explain political attitudes related to authoritarianism, gun rights, and civic participation.

    Public discussions often center on a purported masculinity crisis, pointing to shifting economic prospects for men and their alignment with extreme political ideologies. Political analysts typically rely on male and female categories to explain voting gaps and policy preferences. Claire Gothreau of Lebanon Valley College and Amanda Friesen of the University of Western Ontario argue that this binary framework obscures immense variation within each group. They propose measuring masculinity and femininity as continuous, distinct identities.

    Using a continuous measurement scale, a person can identify as highly masculine, highly feminine, both, or neither, regardless of their sex assigned at birth. In the past, social scientists measured masculinity by asking about stereotypically gendered personality traits or adherence to cultural norms like toughness and anti-femininity. Other frameworks treat manhood as a precarious social status that men feel pressure to defend when threatened. Gothreau and Friesen advocate for a more direct approach that asks people to rate how masculine or feminine they feel.

    This method treats gender as a subjective sense of self. The researchers conducted three separate analyses to test whether this self-perceived identity holds more explanatory weight than binary categories alone. By examining intra-gender variation, they aimed to show how men differ from other men, and women from other women, in ways that shape their political realities.

    In their first analysis, Gothreau and Friesen analyzed survey data from 1,017 adults in the United States collected in 2022. Participants reported their categorical gender alongside where they placed themselves on continuous scales of masculinity and femininity. They also answered questions about their political participation, which included activities like signing petitions, protesting, and donating to campaigns. The researchers controlled for factors such as age, race, education, income, and political party identification to ensure that any correlations were not simply the result of other demographic traits.

    The results showed that binary gender was not a statistically significant predictor of political participation once continuous gender identity was included in the statistical models. Instead, participants who reported higher levels of either masculinity or femininity were more likely to engage in political activities. Predicted values hinted that identifying in ways that differ from traditional gender expectations, such as men reporting high femininity or women reporting high masculinity, might be especially linked to civic engagement, though in this first survey those differences were not statistically significant. The researchers suggest that individuals who view their gender in non-traditional ways might feel their identity is inherently political, motivating them to participate more frequently in the democratic process.

    To see if these patterns held across different contexts, the researchers conducted a second analysis using survey data from 1,043 adults in 2020. This survey included the same demographic and gender identity measures but added questions about attitudes toward issues of force, specifically gun rights and the death penalty. They again controlled for socioeconomic and demographic variables.

    The second survey replicated the participation results from the first analysis, again showing that atypical gender identification correlated with higher political involvement. Regarding policy attitudes, the results varied by topic and gender category. Among men, higher masculinity predicted stronger support for gun rights, while higher femininity predicted lower support for the death penalty.

    Among women, higher masculinity was associated with lower support for the death penalty, while continuous gender identity had a more limited relationship with gun rights attitudes. The authors note that masculinity does not uniformly increase support for aggressive or conservative policies across the board. Its political consequences depend heavily on both the issue in question and the binary gender of the respondent.

    In a third analysis, Gothreau and Friesen examined how continuous gender identity relates to broader worldviews that dictate how people think about social order. They surveyed 1,200 participants in 2022, measuring their alignment with Right-Wing Authoritarianism and Social Dominance Orientation. Right-Wing Authoritarianism measures deference to traditional authority, obedience, and conventionalism. Social Dominance Orientation captures a preference for hierarchy and inequality among social groups.

    The researchers found no strong relationship between continuous gender identity and Social Dominance Orientation. They did detect correlations regarding Right-Wing Authoritarianism. Among men, higher masculinity correlated with higher levels of authoritarian attitudes, whereas higher femininity correlated with lower authoritarianism.

    Among women, the pattern reversed, with higher masculinity predicting lower authoritarianism. The findings indicate that traditional gender identification aligns more closely with authoritarian worldviews, while atypical gender identification resists those frameworks. Much like the findings on force issues, the ideological meaning of a masculine identity hinges on how it aligns with societal expectations for a person’s biological sex.

    The relationships identified in the paper are correlational. The survey data cannot determine whether holding a specific gender identity causes a person to adopt certain political beliefs, or if holding certain political beliefs makes a person more comfortable reporting a non-traditional gender identity. It is possible that individuals with liberal worldviews simply feel more at ease describing themselves in ways that challenge binary norms. Additionally, self-reported measures of femininity and masculinity are subject to social desirability bias, meaning participants might answer in ways they think are viewed favorably by others.

    Future research will need to untangle the order in which these identities and political preferences develop. The authors suggest that longitudinal studies tracking individuals over time, or studies utilizing genetically informed samples, could reveal whether a strong sense of masculinity leads to specific policy preferences or if the two emerge simultaneously. They also note that researchers should investigate aspirational masculinity, looking at the gap between how masculine men feel and how masculine they think they should be. This discrepancy could help explain aggressive political behaviors or feelings of grievance among voters who feel they are falling short of societal gender ideals.

    The study, “Rethinking masculinity in politics: Measuring what matters,” was authored by Claire Gothreau and Amanda Friesen.

    TITLE: Two kinds of political alienation pull support for violence in opposite directions, study finds

    URL: psypost.org/two-kinds-of-polit

    A survey of more than 5,000 adults in four European countries found that people who felt their group was excluded from society were more likely to endorse political violence. Political alienation was not linked to violence endorsement on its own, but depending on its form, it either strengthened or weakened the connection between feeling excluded and endorsing violence. The paper was published in Psychology of Violence.

    Political violence remains a serious challenge for democratic societies. It raises important questions about why some people come to support the use of force to achieve political goals while others do not. One factor that may contribute to such attitudes is perceived social exclusion, or the feeling that one’s group is unfairly treated, disrespected, or denied opportunities to participate fully in society.

    People who feel excluded in this way may develop a strong sense of injustice and become more willing to justify violence as a way of addressing their grievances. Another potentially important factor is political alienation, which refers to feelings of estrangement from the political system and its institutions. Political alienation can take different forms, including distrust of democratic institutions (called institutional alienation) and a sense of powerlessness and hopelessness about one’s ability to influence outcomes (efficacy alienation).

    Although these alienation experiences tend to occur together, researchers suggest that they may have different relationships with support for political violence. For example, people who feel powerless and hopeless about their ability to influence political outcomes may be particularly likely to justify violence when they also feel socially excluded. In contrast, those who have lost trust in political institutions may simply withdraw from political life rather than support violent action.

    Tahir Abbas of Aston University in the United Kingdom examined the connections between perceived social exclusion, political alienation, and the endorsement of violence. Abbas expected that people who felt more excluded would be more likely to endorse violence, and that alienation would not simply pass along or add to this effect but would instead shape how strongly exclusion and violence endorsement were linked. Specifically, efficacy alienation was expected to strengthen this link, while institutional alienation was expected to weaken it.

    The study analyzed data from a survey funded by the European Commission’s Horizon 2020 program and conducted online between 2021 and 2023 through a professional survey panel provider. The 5,501 participants came from the United Kingdom (2,535), the Netherlands (1,963), Denmark (635), and Norway (368). The samples were designed to reflect each country’s population in terms of age, gender, education, and religion, although more educated people were somewhat overrepresented, as is common in online panels.

    The survey measured perceived group-based exclusion with six items, such as feeling humiliated because of one’s background, feeling that one’s religion is treated badly, and perceiving media bias against people like oneself. Institutional alienation was assessed with items such as whether democracy works for people like oneself and confidence in local politicians, while efficacy alienation was assessed with two items: that people like oneself have no power in society, and that one has no future. Violence endorsement was measured with a single statement: “Sometimes people need to use violence to achieve their goals.”

    Support for violence was a minority position, with about 8.5% of participants strongly agreeing with the statement. Participants who felt more excluded were more likely to endorse violence, and this link appeared in all four countries. Political alienation was not associated with violence endorsement once exclusion was taken into account, and it did not explain the link between exclusion and violence endorsement.

    Instead, as predicted, alienation shaped the strength of that link, and its two forms worked in opposite directions. Among participants high in efficacy alienation, feeling excluded was much more strongly associated with endorsing violence. Among participants high in institutional alienation, the link between exclusion and violence endorsement was weaker, though still present.

    The analyses also identified two broad groups of participants that appeared in every country. A majority (59%) reported relatively low exclusion and alienation, and only 0.5% of them strongly endorsed violence. Among the remaining 41%, who reported higher exclusion and alienation, about 20% strongly endorsed violence, although roughly four in five did not.

    “This study finds that perceived exclusion is consistently associated with support for political violence, that political alienation has no independent association, and that alienation instead conditions the grievance–endorsement relationship in opposing directions across its institutional and efficacy facets. Political alienation is best understood as a conditional catalyst, not a cause or a brake,” Abbas concluded.

    “What they [the findings] suggest, tentatively but consistently, is that the texture of political estrangement—whether people withdraw from institutions or feel personally powerless before them—matters more for support for violence than its mere presence,” Abbas added.

    Abbas suggests that efforts to strengthen people’s sense that they can influence outcomes that matter to them may do more to weaken the link between grievance and support for violence than campaigns aimed only at boosting trust in institutions, though this would need to be tested directly. The author also cautions that security measures that make whole communities feel stigmatized could deepen the sense of exclusion that underlies this link.

    The study contributes to the scientific understanding of psychological correlates of political violence. However, it should be noted that the design of this study does not allow any causal inferences to be derived from the results. Violence endorsement was also measured with a single question about attitudes, not behavior, and most people who hold such views never act on them.

    All measures were self-reported, so some participants may have been reluctant to admit supporting violence. The way the measures were constructed was partly exploratory and needs to be confirmed in other data. The overall moderating role of alienation also varied across countries, appearing most clearly in the Netherlands, and the findings may not apply outside established democracies.

    The paper, “From Grievance to Endorsement: Political Alienation as a Conditional Catalyst, Not a Cause, of Support for Political Violence,” was authored by Tahir Abbas.

    TITLE: New brain atlas reveals thousands of overlooked microproteins linked to Alzheimer’s disease

    URL: psypost.org/new-brain-atlas-re

    Researchers have mapped thousands of tiny, previously uncataloged proteins in the human brain, revealing that many of these molecules are altered in Alzheimer’s disease. The study, published in Nature Aging, provides a detailed catalog that links specific short proteins to brain cell energy production and genetic regulation. These discoveries suggest that traditional gene databases capture only a fraction of the brain’s functional molecules.

    Genetic databases act as reference dictionaries for biologists, categorizing the DNA sequences that cells translate into functional proteins. For decades, standard scientific practice excluded sequences that code for very short proteins, often called microproteins. These molecules typically contain fewer than 150 amino acids, the basic building blocks of proteins. Because of their short length, they are difficult to detect using standard laboratory equipment.

    Microproteins originate from small open reading frames, which are continuous stretches of genetic code capable of being translated into proteins. Many of these regions are located within or near larger, well-known genes. As a result, standard genetic sequencing often attributes any activity in these areas to the primary gene, missing the activity of the smaller microprotein.

    To understand the role of these hidden molecules in brain aging and neurodegeneration, Salk Institute for Biological Studies researchers Brendan Miller and Alan Saghatelian led a team to search for them in human brain tissue. They aimed to create a comprehensive atlas of microproteins in the frontal cortex, a brain region heavily impacted by Alzheimer’s disease.

    The researchers first constructed a custom genetic database. They used advanced RNA sequencing on tissue from 12 postmortem human brains to document the specific genetic instructions present in the frontal cortex. They appended these instructions to the standard reference database of known human proteins.

    Using this updated reference, the team analyzed mass spectrometry data from 610 brain samples. Mass spectrometry is a technique that identifies proteins by breaking them apart and measuring the mass of the fragments. This initial search yielded 4,321 microproteins. More than 3,000 of these were considered unreviewed, meaning they had not been cataloged in standard, manually curated protein databases.

    To verify that these unreviewed microproteins were genuine, the researchers cross-referenced their data with ribosome profiling. This technique maps where ribosomes, the cellular machines that build proteins, actively attach to genetic material. They also applied a deep learning tool called PROSIT to evaluate the quality of the mass spectrometry fragments.

    This deep learning program predicts what a true protein fragment should look like, allowing the researchers to filter out false positives. This filtering process identified 1,067 unreviewed microproteins with strong, highly confident evidence of existing in the brain.

    Next, the team investigated whether these microproteins change in relation to Alzheimer’s disease. They compared mass spectrometry data from individuals without the disease to data from individuals with symptomatic Alzheimer’s disease.

    The researchers found dozens of microproteins with altered levels in the brains of individuals with Alzheimer’s disease. For example, a microprotein derived from the BCL3 gene was less abundant in symptomatic individuals. Conversely, a microprotein from the RAB3C gene was more abundant. When the team introduced these specific microproteins into laboratory-grown human microglia, the brain’s primary immune cells, they found that the proteins remained stable and occupied specific areas inside the cells.

    The researchers then explored how these microproteins are regulated. Because many microproteins are encoded by DNA located near larger, well-documented genes, the team examined whether the two are produced together. They compared the RNA levels of the microprotein sections with the RNA levels of the primary genes.

    They discovered that about half of the microproteins were regulated independently of their larger parent genes. In many cases, the amount of microprotein RNA changed in Alzheimer’s disease while the RNA for the main gene did not. This independent regulation was confirmed in a separate dataset of brain tissue from another cohort of patients.

    The team determined that this separation likely results from alternative splicing, a process where cells cut and paste RNA segments differently to create distinct protein products. They identified specific patterns near these cut sites that attract RNA-binding proteins, suggesting a regulatory mechanism that goes awry during neurodegeneration.

    The researchers focused deeply on a microprotein encoded by the MKKS gene. Standard databases list the primary product of MKKS as a large protein linked to a rare developmental disorder. The team wanted to verify if this held true in the adult brain.

    Through their analysis, they found that the small microprotein, rather than the large primary protein, was the dominant product of the MKKS gene in the frontal cortex. The mass spectrometry data showed thousands of fragments matching the microprotein but almost none matching the large protein. The levels of this microprotein were also lower in the brains of people with symptomatic Alzheimer’s disease.

    To understand its function, the researchers mapped out which other genes were active at the same time as the MKKS microprotein. They found a strong overlap with genes involved in the function of mitochondria, the energy-producing structures within cells.

    The team then conducted experiments in laboratory microglia to test this mitochondrial connection. Using a gene-editing tool called CRISPR, they deleted the specific DNA sequence that produces the MKKS microprotein without altering the main gene. They then ran a stress test on these modified cells to measure their oxygen consumption rate. Microglia lacking this microprotein showed a reduced ability to consume oxygen and produce energy, confirming its role in cellular respiration.

    Finally, the researchers investigated pseudogenes, which are mutated genetic sequences generally considered to be inactive or broken. They reviewed the RNA and ribosome data to see if these regions might actually produce microproteins.

    They found evidence that multiple pseudogenes are actively translated into microproteins. One such microprotein, derived from a pseudogene called ACTBP7, is related to the proteins that form the structural framework of a cell. When the researchers added the ACTBP7 microprotein to laboratory microglia, it altered the distribution of the cells’ structural fibers.

    While this atlas identifies many previously unknown brain molecules, the lack of mass spectrometry detection for a specific sequence does not mean the protein is absent from the brain. Some microproteins may simply fall below the detection limits of current laboratory equipment. In addition, the exact genetic pathways that produce many of these short proteins still need to be fully mapped.

    Finding a microprotein with altered levels in an Alzheimer’s disease brain does not mean the molecule causes the disease. These changes might merely reflect a cell’s response to damage or altered regulatory processes. Future research will need to manipulate these individual microproteins in living systems to distinguish between those that drive neurodegeneration and those that are simply markers of cellular stress.

    The study, “A microprotein atlas of the human frontal cortex in Alzheimer’s disease,” was authored by Brendan Miller, Eduardo Vieira de Souza, Calvin Lau, Joan M. Vaughan, Victor J. Pai, Servando Giraldez, Andréa Rocha, Jolene K. Diedrich, Clodagh C. O’Shea, David A. Bennett, and Alan Saghatelian.

    TITLE: The menstrual cycle may shape how much cannabis women use, new research suggests

    URL: psypost.org/the-menstrual-cycl

    A new longitudinal study indicates that the amount of dried cannabis flower consumed by naturally cycling individuals with premenstrual symptoms fluctuates across the menstrual cycle, peaking in the days just before menstruation and rising again around ovulation. These premenstrual increases in cannabis consumption were particularly pronounced on days when individuals experienced worse-than-usual emotional sensitivity or interpersonal conflict. The findings, published in Addictive Behaviors, suggest that both symptom management and hormone-linked changes in reward processing may shape patterns of cannabis consumption across the reproductive cycle.

    Menstrual cycles are driven by rhythmic changes in ovarian hormones, primarily estradiol (the main form of estrogen in reproductive-age females) and progesterone. A typical cycle has two stages: the follicular phase, spanning from the first day of menstrual bleeding until ovulation (when an ovary releases an egg), and the luteal phase, following ovulation until the next period begins.

    In people with premenstrual disorders, such as premenstrual dysphoric disorder (a severe form of premenstrual syndrome marked by emotional and physical symptoms) or the premenstrual worsening of underlying mood conditions, substantial cyclical mood and behavioral changes in the days leading up to menstruation reflect a heightened sensitivity to normal hormone shifts.

    Although men have historically used cannabis at higher rates than women, rising female consumption has narrowed that gap. Women tend to meet criteria for cannabis use disorder after fewer years of use than men and experience more severe withdrawal symptoms, pointing to a need to identify female-specific factors in substance use. Two emotion-based theories help explain why substance use may shift across the cycle: the self-medication theory proposes that people use substances to relieve negative moods that rise during the luteal and perimenstrual phases, while the reward-sensitivity theory suggests that pre-ovulatory estradiol surges heighten the brain’s responsiveness to pleasurable stimuli.

    While patterns matching both theories appear in alcohol, nicotine, and stimulant use, evidence for cannabis has been inconclusive. A 2021 study of nearly daily cannabis users with premenstrual dysphoric disorder found that consumption rose during the premenstrual and menstrual phases, peaked in the follicular phase, and decreased around ovulation and the mid-luteal phase. However, that study confirmed the disorder using only depressed mood rather than all core emotional symptoms and did not biologically verify the day of ovulation.

    Study lead author Gianna Zorzini, senior author Jennifer L. Gordon, and their colleagues in the Reproductive Mental Health Research Unit in the Department of Psychology at the University of Regina designed the new study to address both limitations.

    “Cannabis use among women has increased in recent years, yet we still know relatively little about why and when women use cannabis,” Zorzini told PsyPost. “We wanted to better understand whether cannabis use changes throughout the menstrual cycle and how these changes relate to emotional symptoms, particularly those associated with premenstrual disorders.”

    The researchers analyzed pre-treatment data from a registered clinical trial evaluating a self-help program for premenstrual disorders, with the raw dataset kept confidential. Sixty-four naturally cycling individuals aged 18 to 42 in Canada and the United States, recruited through a premenstrual disorder advocacy organization’s social media channels, completed the tracking phase. All had regular 21-to-35-day cycles and a diagnosed or suspected premenstrual disorder, and could not be pregnant, breastfeeding, using hormonal contraceptives or hormone medications, or receiving cognitive or dialectical behavior therapy. Participants completed daily surveys each evening at 6:00 p.m. across two to three menstrual cycles.

    At baseline, participants completed clinical interviews and questionnaires assessing depression, anxiety, stressful life events over the past six months, and lifetime traumatic events. Reflecting a help-seeking sample, roughly 83 percent of the 64 participants met criteria for another psychiatric diagnosis and about 44 percent were taking antidepressants. Each evening, participants logged whether they had used cannabis the previous day and reported the amount by product type: grams of dried flower, milligrams of tetrahydrocannabinol (THC, the main psychoactive compound in cannabis) in edibles or oils, or hits of concentrate. They also rated daily symptoms on a six-point scale covering core emotional difficulties including depressed mood, anxiety, mood swings, anger or irritability, emotional or rejection sensitivity, and interpersonal conflict.

    Using these daily logs, the team distinguished participants whose premenstrual disorder was confirmed through daily tracking, defined as at least a 30 percent premenstrual increase in four or more symptoms in at least one cycle, from those meeting only provisional criteria during their initial interview. That cutoff, chosen based on prior evidence of premenstrual impairment, is slightly broader than the formal diagnostic standard for premenstrual dysphoric disorder, which requires five symptoms across two cycles.

    Because cycle lengths vary between and within individuals, simply counting days can misalign hormonal phases. The researchers combined self-reported menstruation dates with urine tests detecting luteinizing hormone surges, which typically precede ovulation by about a day. They then used phase-aligned cycle time scaling, a method that maps each cycle onto a continuous timeline anchored to both menstruation onset and ovulation. Generalized additive mixed models, which capture curved, non-linear trends over time, were used to test whether cannabis likelihood and quantity fluctuated cyclically, followed by exploratory models testing whether daily symptoms or baseline traits changed the shape of those cycle patterns.

    Of the 64 participants, 25 used cannabis at least once across 47 to 87 tracked days (averaging 61.70 days and totaling 1,449 observations). Ovulation was confirmed by urine test for 49 cycles and estimated by counting backward for 5 cycles, and excluding those 5 cycles did not change the results. Compared to the 39 non-users, cannabis users reported more recent stressful life events (averaging 4.8 versus 2.7) and had higher odds of having a premenstrual disorder confirmed through daily tracking (80 percent versus 53.8 percent, representing roughly four times the odds, or nearly five times the odds after adjusting for age, country, and stressful events).

    Users consumed cannabis on an average of 27.48 days, or 44.4 percent of tracked days. Eighty percent of users consumed edibles or oils at least once (178 observations, averaging 3.56 milligrams of THC and ranging from 0.02 to 50.00 milligrams), and 68 percent used dried flower (341 observations, averaging 0.95 grams and ranging from 0.02 to 5.00 grams). Another 32 percent used concentrates (95 observations, averaging 3.91 hits and ranging from 1 to 10 hits) and 16 percent used other THC products, with both of these categories excluded from cycle modeling due to few observations.

    Across the group, the daily probability of using cannabis showed no statistically significant cyclical pattern, whether looking at overall cannabis use, dried flower, or edibles and oils. Participants differed substantially from one another in their average likelihood of use, and person-specific cyclical patterns appeared for overall cannabis use and for edibles and oils, though not for dried flower. However, the quantity of dried flower consumed on use days followed a cyclical pattern across the group when anchored to menstruation onset, peaking premenstrually and rising again around ovulation. The authors suggest that earlier research may have missed this ovulatory rise because it did not biologically confirm when ovulation occurred.

    When the dried flower data were anchored to ovulation instead of menstruation onset, the group-level trend for quantity was not statistically significant, and individual patterns varied widely around ovulation, giving reason to treat the group-level pattern with some caution. The authors note that this person-to-person variability may have obscured a shared group pattern, or the sample may have been too small to detect one.

    In the ovulation-anchored model, among the roughly 16 dried-flower users, about half showed only a premenstrual increase, three showed only an ovulatory increase, and five showed both. The authors describe the evidence for the ovulatory rise as weaker than for the premenstrual one, since fewer individuals showed it. For THC-infused edibles and oils, the group-level cyclical pattern in milligrams consumed on use days was not statistically significant, despite a slight upward trend right after menstruation onset and substantial variation in person-specific trajectories.

    “We were surprised that increases in cannabis use before menstruation were more common than increases around ovulation,” Zorzini said. “Although we observed both patterns, they differed considerably between women. This raises interesting questions about why some women show different consumption patterns across the cycle.”

    “Not everyone used more cannabis at the same points in their menstrual cycle or to the same extent,” she added. “This suggests that individual differences are important and that there is no single pattern that applies to everyone. Larger studies are needed to better understand what explains these differences.”

    In exploratory within-person analyses, daily fluctuations in core emotional symptoms changed the shape of the cyclical pattern for dried flower quantity. Higher-than-usual daily emotional symptoms were associated with greater premenstrual dried flower consumption, whereas lower-than-usual symptoms corresponded with lower premenstrual intake. Around ovulation, by contrast, lower-than-usual emotional symptoms were tied to greater dried flower consumption than higher-than-usual symptoms.

    After adjusting for multiple comparisons, higher-than-usual emotional or rejection sensitivity and interpersonal conflicts were the specific daily symptoms that shaped the premenstrual rise in dried flower quantity. Daily emotional symptoms had no statistically significant link to the daily likelihood of use or to edible and oil quantities.

    “Women tended to use more cannabis on days when they experienced greater emotional sensitivity or more conflicts with others than usual,” Zorzini noted. “This suggests that emotional experiences may play a role in cannabis use, although we cannot determine whether women were using cannabis specifically to cope with these symptoms.”

    Preliminary exploratory analyses suggested that baseline characteristics also shaped consumption curves, though the authors note these tests had low statistical power and very small, uneven subgroups. Stronger premenstrual increases in dried flower quantity appeared among the 20 users whose premenstrual disorder was confirmed through daily tracking (compared to the 5 users who met only provisional criteria), older participants, those with more past traumatic events, and the 17 users not taking antidepressants (compared to the 8 who were). For edibles and oils, older age was linked to a steeper increase during the early luteal phase, in the days soon after ovulation. Because age and trauma history were modeled separately and showed a positive correlation that was not statistically significant (r = 0.33), their independent contributions remain uncertain.

    The authors suggest that the rise in dried flower use around ovulation aligns with the reward-sensitivity theory, as pre-ovulatory estradiol surges can heighten responsiveness to the rewarding effects of substances at a time in the cycle when emotional symptoms are relatively low. They also suggest that dried flower, which is usually smoked or vaped and acts quickly, may have been preferred for fast relief from premenstrual symptoms, whereas ingested edibles and oils act more slowly, though the study did not record how participants consumed their cannabis. Similarly, the researchers propose that individuals not taking antidepressants may use cannabis premenstrually to cope with mood changes, while those on antidepressants may already have their cyclical symptoms buffered pharmacologically.

    There are a few things to keep in mind when interpreting these results. Because the study relied on observational tracking, it cannot establish whether premenstrual symptoms drove higher cannabis use or whether cannabis altered subsequent symptom ratings. Dried cannabis flower often contains cannabidiol (CBD), a non-intoxicating compound that some research suggests may ease menstrual symptoms, so cannabis itself may have affected the symptoms participants reported, and the study did not measure THC and CBD concentrations.

    “An important limitation is the limited generalizability, as all women in our study suspected they had a premenstrual disorder because they experienced emotional changes throughout their menstrual cycle,” Zorzini explained. “Our findings may therefore be particularly relevant to women who experience premenstrual emotional symptoms, but we cannot assume that the same patterns apply to all women.”

    The small sample of 25 cannabis users also limits generalizability, especially for the exploratory between-person comparisons, where limited statistical power can obscure true differences or inflate observed effect sizes. In addition, the researchers did not assess consumption motives or histories of clinical substance use disorders, leaving it uncertain whether the observed patterns reflect casual use, targeted symptom relief, or clinical dependence.

    Future studies with larger, more balanced samples will be needed to verify whether these cyclical peaks in dried flower use replicate and whether baseline vulnerabilities to reward-seeking behaviors explain why a subset of users consumed more cannabis around ovulation. Incorporating direct measures of product potency, ingestion methods, and daily motives could help explain why people reach for specific cannabis products across the cycle and inform female-tailored prevention and treatment approaches.

    “Our next step is to study larger and more diverse groups of women,” Zorzini told PsyPost. “We hope to better understand why and when cannabis use changes throughout the menstrual cycle for some women but not for others, and whether these patterns are related to emotional symptoms. Ultimately, this research could help inform more individualized prevention and treatment approaches.”

    “Women have historically been underrepresented in substance use research, and factors related to the menstrual cycle have often received limited attention,” she added. “We hope our study encourages more research that considers women’s unique experiences and the factors that may influence their substance use.”

    The study, “Menstrual cyclicity of cannabis use: a longitudinal study using phase-aligned cycle time scaling (PACTS),” was authored by Gianna Zorzini, May Ly, Taryn Wahl, and Jennifer L. Gordon.

    TITLE: Racial attitudes and economic optimism predict Trump support among Asian American voters

    URL: psypost.org/economic-views-and

    Asian American voters who supported Donald Trump in the 2024 election tended to hold particular economic evaluations, alongside specific racial and anti-immigrant attitudes. These patterns mirror trends seen in other racial groups, providing new insight into the shifting political preferences of a rapidly growing segment of the American electorate. The findings were published in the journal Political Research Quarterly.

    Asian Americans are the fastest-growing single-race group in the United States. Historically, many racial minority groups have favored Democratic candidates in national elections. Recent presidential races have revealed shifts in these patterns, with some voter segments increasing their support for Republican candidates. Political scientists aim to understand the specific attitudes associated with these changing voting decisions.

    In the past, political behavior research often emphasized issue-based voting and economic concerns. Voters tend to evaluate the economy and select candidates they believe will maximize their future financial well-being. Researchers want to know how strongly these foundational economic views affect voters from marginalized backgrounds.

    For racial and ethnic minorities, identity-based factors usually play a prominent role in voting. Researchers study concepts like “linked fate,” which measures how much a person believes their individual life chances depend on the overall success of their racial group. Another identity-based factor is racial resentment, a metric used in political science to gauge anti-Black prejudice. Studies evaluate how these attitudes correspond with political choices.

    Political scientists Joyce H. Nguy of Golden West College, Nathan K. Chan of Loyola Marymount University, and Jessica HyunJeong Lee of California State University, Fullerton, led the research. They designed a study to test how economic and racial elements interacted during recent presidential campaigns. They aimed to provide a comprehensive analysis of Asian American voting behavior across the 2016, 2020, and 2024 elections.

    The researchers analyzed data from the Collaborative Multiracial Post-Election Survey. This is a large national survey featuring oversamples of minority populations. The data included responses collected in the months immediately following the last three presidential elections.

    The total sample contained 24,061 eligible voters who reported casting a ballot. This included a large sample of 5,776 Asian American voters across the three election cycles. The researchers compared their responses to those of Black, Latino, and White voters to see if Asian American voting patterns were unique or reflective of broader national trends.

    The survey asked participants about their presidential vote choice. It also included questions about their economic outlook, feelings of racial solidarity, attitudes toward Black Americans, and opinions on immigration. The researchers then used statistical models to identify which attitudes correlated with voting for Donald Trump.

    Looking at the raw numbers, the researchers noted that about 38 percent of Asian American voters supported Trump in the 2024 presidential election, while 57 percent voted for Kamala Harris. Support varied somewhat by national origin. Vietnamese and Filipino Americans supported Trump at the highest rates within the demographic, while Japanese Americans were the least likely to vote for him.

    The researchers noted that these baseline voting levels were similar to those seen in the Latino electorate in 2024, where roughly 38 percent also supported Trump. Support for the Republican candidate remained much lower among Black voters at around 18 percent. White Americans were the only group where a majority supported Trump.

    When running their statistical models, the researchers found that economic evaluations were strongly associated with vote choice in 2024. Survey participants were asked if they were optimistic or pessimistic about their future family income and job prospects. Optimism about the economy was linked to a higher likelihood of voting for Trump among Asian Americans.

    This economic trend was not isolated to one demographic. Black, Latino, and White voters who expressed economic optimism in the 2024 survey were also more likely to have voted for the Republican candidate.

    Alongside the economy, racial solidarity played a major role in how Asian Americans voted. The survey measured linked fate by asking respondents how much they felt their own lives were affected by what happens to other people of their same race. Stronger feelings of linked fate correlated with a lower likelihood of supporting Trump.

    This effect was heavily present in 2020, a year marked by a spike in anti-Asian hate incidents during the COVID-19 pandemic. The influence of linked fate persisted into 2024, showing that racial solidarity continued to shape political choices even as the national dialogue shifted. A similar dynamic appeared among Black voters, where strong linked fate predicted lower Trump support. Linked fate did not have a statistically significant relationship with opposition to Trump among Latino and White voters in 2024.

    The researchers also examined out-group racial attitudes. They measured this using standard survey questions designed to capture racial resentment. Higher levels of racial resentment were associated with a greater likelihood of voting for Trump among Asian Americans.

    This pattern extended to other groups as well. In the 2024 election, racial resentment predicted higher Trump support among all non-Black voter groups. The researchers noted this relationship was consistent across the 2016, 2020, and 2024 elections for Asian American, Latino, and White voters alike.

    Views on immigration provided another strong predictor of voting behavior. The survey asked if respondents felt immigrants strengthened the country or if they weakened American culture and the economy. Agreeing that immigrants weaken the country was linked to a higher probability of voting for Trump.

    This correlation appeared heavily among Asian Americans, which is notable because they are predominantly a population with immigrant origins. The researchers suggest that some members of immigrant communities may adopt assimilationist views or a belief in strict meritocracy. These psychological mechanisms can lead to conservative preferences that diverge from the broader collective interests of immigrants. Anti-immigrant sentiment was similarly associated with Trump support among Latino, Black, and White voters.

    The study relies on observational survey data. This means the statistical models can only show associations between attitudes and voting behavior. The data cannot prove that a specific belief definitively caused a person to vote a certain way.

    Additionally, the survey questions measuring economic attitudes changed over time. In 2016 and 2020, respondents were asked to select the most important issues they wanted the government to address. In 2024, they were asked about their personal economic optimism. Because the metrics differ, it is difficult to accurately measure how much the influence of the economy changed between individual election years.

    The researchers also pointed out that changes in overall voter support might relate to voter turnout rather than individuals changing their political views. The data suggests that Asian Americans who turned out to vote in 2024 favored Trump at higher rates than those who stayed home. Future studies will need to explore how much of the shifting political landscape is driven by fluctuating turnout versus shifting partisan loyalties.

    Further research is needed to see if these racial and economic considerations continue to operate the same way in future election cycles. Scientists also want to study if these patterns hold steady when Donald Trump is not a candidate on the ballot.

    The study, “How Election Fundamentals and Racialized Considerations Shape Asian American Vote Choice Through the Trump Era,” was authored by Joyce H. Nguy, Nathan K. Chan, and Jessica HyunJeong Lee.

    TITLE: Women want to talk about sex with their close friends more often, study finds

    URL: psypost.org/women-want-to-talk

    Women in the United States rarely talk about sex with their close female friends, even though women generally wish those conversations happened more often and tend to see them as helpful, according to new research published in The Journal of Sex Research.

    Many women anticipate that raising topics they avoid would make friends uncomfortable, with smaller shares expecting to be judged or seen as weird or gross. These findings suggest that unspoken social rules and fears of negative reactions continue to surround how women discuss their sexual lives, even within their closest friendships.

    Social Norms and the Double Standards of Sex Talk

    Peer sexual communication refers to the conversations friends have with one another about sex-related matters, ranging from birth control and sexually transmitted infections to sexual pleasure, fantasies, and relationship difficulties. For many women, close female friends serve as a primary sounding board for making sense of sexual experiences, seeking advice, and finding emotional support without the risk of romantic rejection. At the same time, these conversations are shaped by social norms, which are the unwritten rules of behavior within a group that dictate what actions or topics of conversation are acceptable or off-limits.

    Women navigating conversations about sex often contend with a cultural double standard that rewards men for sexual activity while stigmatizing women for the same behaviors, alongside stereotypes portraying women, particularly as they age, as uninterested in sex. Even within close female friendships, women encounter mixed messages that both encourage sexual agency and penalize openness. This pattern aligns with an earlier study of young women, which indicated that conflicting social expectations that simultaneously celebrate sexual exploration and stigmatize female sexual activity can produce ambivalence, confusion, and shame even during consensual encounters.

    When women do talk with their friends about sex, their discussions tend to stay within safe boundaries, focusing on pregnancy prevention, disease protection, or general emotional reassurance rather than specific sexual acts or pleasure. In a 2018 study of adult women conducted by Katrina L. Pariera, the lead author of the new paper, supportive and emotionally expressive conversations with female friends were associated with higher sexual self-confidence and self-esteem, while information-focused communication was associated with greater awareness of safer sex methods, although both types of communication were also linked to overestimating how much peers approved of risky sexual behavior.

    Most prior research on social norms has examined perceived norms, which reflect what an individual guesses a broad group of peers does or approves of, rather than collective norms, which represent the actual behavioral patterns shared within a specific social circle such as close friends. Norms are maintained through social sanctions, the negative social reactions people anticipate facing if they break a group rule, and these sanctions are supported by underlying rationales, which are the moral or practical justifications for why a rule exists.

    To examine how these collective norms, sanctions, and rationales operate across adulthood, Pariera, an associate professor of communication at San Diego State University, and her colleagues Aliyah Blasband and Maggie Job studied women’s sexual communication habits and attitudes with their close female friends.

    “Sexual communication is necessary to good sexual health and wellbeing, but talk about sex is stigmatized, especially for women,” Pariera told PsyPost. “Many women turn to their close friends to talk about sex, because our friends can be great at giving support and advice. Through this communication our friends convey, often subtly, what is normal, typical and acceptable. I really wanted to understand all of this more deeply – what kinds of sex-related topics are women discussing, avoiding, and, more interestingly, why are women hesitant to bring up so many of these topics with their friends?”

    Designing the Survey and Studying Women Across Adulthood

    Because few studies had measured sexual communication norms among friends, the researchers first conducted two preliminary pilot studies using the online research platform Prolific to build and refine their survey questions. In the first pilot study, 40 women aged 18 and older completed an open-ended questionnaire about which sexual topics were acceptable or unacceptable to discuss with female friends, what penalties they expected for bringing up uncommon topics, why friends might react negatively, and what benefits came from these talks. Participants reported that birth control and feminine health were the most acceptable topics, whereas specific sex acts, graphic details, and oversharing were discouraged, and they expressed a widespread desire to normalize talking about sex alongside fears of judgment, disgust, and internal sexual shame.

    Drawing on those open-ended responses, the authors created a draft survey for a second pilot study that added scales measuring perceived benefits, the desire to change existing norms, and internal sexual shame. After testing this draft with 60 women on Prolific and interviewing three women in their 20s and 30s, the team removed several unselected or confusing items and replaced clinical terms such as “low libido” and “cunnilingus” with everyday phrases like “low sex drive” and “getting oral sex.”

    The main study was preregistered on AsPredicted.org in February 2025, and data were collected in November 2025 from U.S. women aged 18 or older who spoke with at least one female friend weekly. To minimize selection bias, the recruitment notice stated that the study examined communication with friends and included sensitive topics, without mentioning sex. Out of 625 women recruited through Prolific, the researchers excluded eight who failed an attention check, six who finished in less than 30% of the median completion time, and three who pasted spam links into the open-ended response, leaving a final sample of 608 women aged 20 to 77, with an average age of 45.09 years.

    Within the final sample, 79.0% of participants identified as straight, 14.4% as bisexual, 3.1% as gay or lesbian, and 2.1% as another sexual orientation; 57.1% identified as White, 9.9% as Black, 5.1% as Asian, 3.6% as Latino or Latinx, and 22.9% did not report their race or ethnicity. Nearly two-thirds (65.2%) were in a steady relationship lasting more than a year, 28.6% were not dating, and participants spoke weekly with an average of 3.09 female friends.

    Participants rated how often they discussed 17 sexual topics with their female friends and how often they thought those topics should be discussed on a 4-point scale from 1 (Never) to 4 (Often), and evaluated seven potential benefits and five statements on normalizing sexual communication on 5-point scales from 1 (Strongly Disagree) to 5 (Strongly Agree). They then selected which of 12 social sanctions they anticipated for bringing up topics they never discussed, rated nine possible rationales for those sanctions, and answered an open-ended question explaining why their friends might react negatively.

    The Gap Between Actual and Desired Conversations

    Overall, the results indicated that sexual conversations among female friends occurred infrequently, with a composite average score of 1.82 out of 4 across the 17 topics, and took place primarily face-to-face or over video chat (82.1%) rather than via text messaging (10.8%) or phone calls (7.1%). The most commonly discussed topics were how often they have sex (discussed by 67.5% of participants, with an average score of 2.27), birth control (65.7%, average of 2.28), and sex that was good (65.5%, average of 2.19), whereas the least discussed were anal sex (26.6%, average of 1.37), pornography (31.0%, average of 1.48), masturbation (33.0%, average of 1.55), and sexually transmitted infections (35.3%, average of 1.59).

    Across every single one of the 17 topics, paired statistical tests showed a reliable gap between actual and desired communication, with women wanting to discuss each topic more often than they currently did (an overall desired average of 2.77 out of 4). The highest desired frequency scores appeared for birth control (3.35), condoms (3.15), sexually transmitted infections (3.09), sexual problems (3.05), and low sex drive (3.05).

    The finding that women infrequently discuss sex with their friends stands in tension with a 2020 daily diary study of female college students co-authored by Pariera, which found that young women engaged in sexual communication an average of 13 times per week, mostly with friends and in casual tones, despite underestimating how often they talked about sex. That earlier study tracked daily interactions among college students aged 19 to 21, whereas the new study surveyed adult women across a much wider age span of 20 to 77 about their general communication habits across 17 specific topics. If women tend to underestimate their own sex talk, retrospective ratings like those in the new survey could understate how often these conversations happen.

    Participants in the new survey generally viewed talking about sex with female friends as beneficial, with an overall average score of 3.44 out of 5, and expressed strong support for normalizing these conversations, averaging 4.18 out of 5. The highest-rated benefits were feeling less alone (3.56), getting help addressing problems (3.54), learning what is typical (3.51), and growing closer to friends (3.49), while support for normalization was highest for making it acceptable to admit to enjoying sex (4.29), to admit to not enjoying sex (4.29), and to talk about sexual problems (4.25).

    In the authors’ reading, the fact that women valued learning what is typical and knowing whether they are doing things the right way (3.22) suggests that even when seeking comfort and validation, women still look to their friends as a benchmark to judge whether their own private sexual behaviors fit within group norms.

    Why Women Hold Back: Fears of Discomfort, Disgust, and Judgment

    When asked what would happen if they brought up a sexual topic they never discussed, 78.6% of the participants expected at least one negative reaction from their friends, selecting an average of 3.07 sanctions out of 12 options, while only 21.4% anticipated no sanctions at all. The most common expected sanction was making a friend uncomfortable (60.2%), followed by fears that a friend would judge them (29.9%), think they were weird (28.5%), look at them weird (27.0%), think they were gross (22.7%), or think they were too sexual (17.4%).

    On the quantitative scale measuring rationales for why friends would react negatively (averaging 2.21 out of 5 overall), the highest-rated rationales involved disgust and explicitness, though even these averaged at or below the scale’s neutral point of 3. Specifically, participants gave the highest ratings to statements that the conversation would be too graphic (2.98), make the friend feel gross (2.78), or put a bad image in their head (2.58). The researchers propose that because disgust tends to fade with repeated exposure, avoiding sex talk may create a self-reinforcing cycle that keeps the topic feeling visceral and uncomfortable.

    To examine the reasoning behind these anticipated sanctions in greater detail, the researchers conducted a content analysis of the open-ended responses from the 469 participants who expected negative reactions and answered the prompt, sorting the written answers into six recurring themes: taboo, disgust and immorality, privacy boundaries, fear of judgment, internalized shame, and religion and culture.

    Many women offered circular explanations rooted in the concept of a taboo, writing simply that sex is not something people talk about because it should not be discussed, while others noted that discussing acts like oral or anal sex would violate a romantic partner’s privacy, particularly when their friends knew their partner well. The authors noted that although many women worried their friends would judge them as “perverted,” “gross,” or “lower class,” not a single participant described having actually been judged by a friend, though the question asked about anticipated reactions rather than past experiences.

    “One of the big takeaways is that women largely want to be free to talk to their friends about sex more than they currently do, but they’re afraid their friends will judge them or be uncomfortable,” Pariera explained. “Those fears may or may not be valid, but a good starting place is to talk about why the topic of sex is taboo for women. This broader meta-conversation could help test the waters for what you and your friends are okay discussing, and might help to make sense of some of our assumptions about each other.”

    The Roles of Age, Religiosity, and Internalized Shame

    In an exploratory analysis, the researchers also calculated correlations (where 0 means no relationship and 1 a perfect one) between the communication measures and five background characteristics: age, education, religiosity, sexual orientation, and internalized sexual shame, omitting political orientation because it overlapped strongly with religiosity.

    All statistically detectable correlations were small to moderate, with none exceeding .32, and several relationships, such as those between age, education, or sexual orientation and the number of anticipated sanctions, were not statistically significant. Being younger and identifying as non-straight showed small associations with more frequent actual and desired sexual communication, higher perceived benefits, and stronger support for normalization (correlations of .18 to .31 in size).

    Higher religiosity was weakly linked to wanting more frequent sexual communication (r = .22) and supporting its normalization (r = .29), yet also to agreeing more with the rationales for sanctioning sex talk (r = .31). Internalized sexual shame was moderately associated with expecting more sanctions (r = .32) and endorsing the rationales for those sanctions (r = .32). The authors suggest this pattern could mean either that women who judge themselves harshly assume others will too, or that people with greater shame spend more time contemplating negative social reactions.

    “One thing that surprised me was that age played a relatively small role in how much women talk or want to talk to their friends about sex,” Pariera noted. “I personally think we tend to overemphasize generational differences, but we also need to look more at if and how aging changes the way we talk to friends about sex.”

    Study Limitations and Future Directions

    There are a few things to keep in mind when interpreting these findings. Because the survey asked women how they imagined their friends would react to undiscussed topics rather than observing real conversations or surveying the friends themselves, the study cannot determine whether close friends actually enforce these social sanctions or whether women are overestimating the risk of making their friends uncomfortable. In addition, because the data were collected at a single point in time, the correlational findings cannot establish whether internalized shame causes women to anticipate more judgment or whether fearing judgment from peers fosters internal shame.

    Pariera also pointed out that simply talking more often is not a cure-all if the tone of those conversations remains critical. “While more open communication is almost always a good thing, communication can also be a tool for reinforcing harmful stereotypes, and creating stigma and shame,” she said. “Focusing on listening non-judgmentally is one key to good communication about taboo topics.”

    The study’s scope was also restricted to U.S. women speaking with female friends they contact at least once a week, and relied on several new scales created by the authors that still require validation across other populations. The findings do not capture how sexual communication norms operate in friendships with men or non-binary peers, with less frequent acquaintances, or in other cultural contexts. The analysis also did not account for how often participants were sexually active, whether they were experiencing sexual difficulties, how long they had been with a partner, or how closely their friends knew their partner, all of which could influence what women feel comfortable sharing.

    Finally, the researchers did not analyze differences across racial or ethnic groups because many participants selected multiple racial categories and 22.9% left the question blank. Future studies could examine how intersectional identities, cultural backgrounds, and communication channels such as text messaging versus in-person talks shape these norms. The authors also suggest that experimental research could test whether media campaigns modeling non-judgmental conversations, or interventions encouraging women who already feel comfortable discussing sex to initiate open conversations, can help reduce the stigma and discomfort surrounding peer sexual communication.

    “I’m planning on interviewing women across the life-span to get a more in-depth understanding of what I found in this study,” Pariera added. “I want to better understand women’s experience talking to their friends about sex, particularly around their experiences with support and validation, but also judgment and silencing.”

    The study, “Norms and Sanctions for Talking About Sex: Women’s Sexual Communication with Friends,” was authored by Katrina L. Pariera, Aliyah Blasband, and Maggie Job.

    A surprising new discovery suggests that fear may cause the brain to blur the line between danger and safety rather than distinguish them more clearly. By observing brain activity in mice using augmented reality, scientists found that memories of threatening and harmless environments began to overlap, potentially allowing faster responses to danger. This "better safe than sorry" survival mechanism could help explain why people with anxiety or PTSD sometimes experience intense fear in completely safe situations.

    TITLE: A simple cognitive reframing strategy reduces sensory brain responses in autistic youth

    URL: psypost.org/a-simple-cognitive

    Mentally reframing an unpleasant physical sensation by describing it like an objective news reporter can quiet activity in sensory areas of the brain in autistic children and teens, according to new research published in the Journal of Child Psychology and Psychiatry. Although a brief session of this mental strategy did not immediately change how unpleasant the autistic participants said the textures felt, brain scans indicated that it reduced neural activity in regions that process touch and sound.

    Many people with neurodevelopmental or psychiatric conditions, including attention-deficit/hyperactivity disorder (ADHD) and anxiety, experience sensory over-responsivity. This condition involves intense, distressing reactions to everyday sensory inputs that most people easily ignore, such as scratchy clothing tags or background hums. Sensory over-responsivity is especially common in autism, where it often interferes with daily routines, social interactions, and emotional well-being, yet few evidence-based treatments exist to ease this distress.

    Part of the challenge in treating sensory sensitivity lies in how the autistic nervous system registers and evaluates physical sensations. For instance, a study of touch responses in autistic adults found that while autistic participants showed weaker automatic skin-sweat responses to touch than non-autistic peers, they reported stronger subjective feelings for both pleasant and unpleasant textures. To see how the brain responds to unpleasant sensations in youth, scientists use functional magnetic resonance imaging (fMRI), a technique that tracks neural activity by measuring changes in blood flow. Findings from a 2015 brain-imaging study by Shulamite A. Green and colleagues indicated that when autistic children encounter scratchy textures or irritating sounds, they display heightened activity in primary sensory areas and in the amygdala, an almond-shaped structure deep in the brain that processes threats and emotions.

    In people without sensory sensitivities, the brain normally gets used to repeated harmless sensations through a process called habituation, which the prefrontal cortex, the frontmost part of the brain responsible for planning and self-control, is thought to help maintain. However, a 2019 neuroimaging study by Green and colleagues showed that autistic youth with severe sensory over-responsivity have weaker communication between the prefrontal cortex and the amygdala, a pattern linked to difficulty sustaining habituation during unpleasant stimulation. Evidence from a 2023 cross-sectional study by Green’s team also indicated that these frontal regulatory circuits mature later in adolescence for autistic youth than for typically developing peers.

    Because sensory over-responsivity has been linked to weaker top-down brain regulation, meaning control from higher-level brain regions, the authors of the new study examined whether actively engaging the prefrontal cortex could dial down sensory hyperactivity. They focused on cognitive reappraisal, a mental strategy commonly taught in talk therapy where a person deliberately changes how they think about an upsetting stimulus to alter their emotional response to it. The new research was led by first author Urvi T. Shah of the University of Washington alongside senior author Green, an associate professor, Friends of the Semel Institute Term Chair, and director of the Sensory Cognitive and Affective Neurodevelopment (SCAN) Lab at the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles.

    “There are almost no evidence-based interventions for sensory over-responsivity even though it makes life very difficult, especially for autistic individuals,” Green told PsyPost. “Much of my work to date has focused on identifying the underlying biological mechanisms of sensory over-responsivity in order to inform treatment.”

    “We have found that autistic kids with sensory over-responsivity tend to activate fewer prefrontal regulatory regions of the brain when they experience aversive sensory stimulation in an MRI brain scanner,” she explained. “We thought this might mean they’re having difficulty regulating their responses to sensory information. Our reappraisal study was designed to determine if we could teach autistic kids to engage prefrontal cortex and reduce their sensory reactivity.”

    The researchers analyzed data from 47 autistic youth and 45 typically developing youth aged 8 to 15, with an average age of 13. The groups were matched on age and IQ (both averaging a Full-Scale IQ of 110 on the Wechsler Abbreviated Scales of Intelligence) and did not differ significantly in sex, ethnicity, or race. Of the 80 autistic and 54 typically developing youth originally recruited, 31 and 9, respectively, were excluded for head movement in the scanner, along with a small number of other exclusions. All included participants passed a practice scan confirming they could lie still, follow instructions, and respond verbally.

    Parents completed the Sensory Experiences Questionnaire to measure how strongly their children reacted to everyday sensory inputs. Autistic participants had higher average sensory over-responsivity scores (77.98) than typically developing participants (40.95). Parents also filled out the Screen for Child Anxiety-Related Emotional Disorders, where autistic youth averaged a score of 26.02 compared to 7.33 in the typically developing group, which the researchers accounted for when examining how sensory symptom severity related to brain activity.

    Before entering the MRI scanner, each participant completed a short training session on how to use cognitive reappraisal. Inside the scanner, they wore noise-canceling headphones and earplugs while an experimenter rubbed their inner left forearm with two mildly unpleasant materials: artificial grass and scratchy wool fabric. Across nearly eight minutes, participants experienced twelve 20-second blocks of touch separated by 13.5-second rest periods.

    Before each 20-second block, a two-second visual and audio prompt instructed the child on how to approach the sensation. During the six “React” trials, participants saw the word “feel” and experienced the texture naturally. During the six “Reappraise” trials, they saw the word “reporter” and mentally described the texture objectively, as if they were a news reporter, to distance themselves emotionally from the discomfort.

    After each block, participants had four seconds to answer “How badly do you feel?” using a handheld button box on a scale from 1 (least bad) to 4 (most bad). One typically developing participant missed more than half of the rating prompts, leaving 47 autistic and 44 typically developing youth in the behavioral analysis.

    Across both groups, participants rated the artificial grass as more unpleasant than the wool sweater fabric, giving the grass an average distress score of 2.34 out of 4 compared to 1.44 for the wool. Only the typically developing group reported lower discomfort during reappraisal, and only for the grass texture, where their average rating showed a small drop of about 0.15 points, from 2.38 during React to 2.23 during Reappraise. In the autistic group, self-reported distress ratings did not show a statistically significant difference between the two conditions.

    Even without a shift in their button ratings, the brain scans indicated that autistic youth altered how they processed touch during reappraisal. When reacting naturally, the only whole-brain difference between the two groups was higher activity among autistic youth in the cerebellum, a structure at the base of the brain involved in coordination and sensory prediction. When participants acted like an objective reporter during reappraisal, the two groups no longer differed significantly in whole-brain activity.

    Comparing the two conditions directly showed that reappraisal reduced activity in the autistic group’s somatosensory cortex, a strip of tissue along the top and sides of the brain that registers touch, and the insula, a deep cortical fold that integrates sensory and bodily signals. By contrast, typically developing youth showed no brain regions with reduced activity during reappraisal, and their somatosensory cortex activity actually edged up slightly when switching from React to Reappraise. The authors suggest that typically developing youth did not need to dial down their primary sensory regions because their baseline sensory responses were lower to begin with.

    Targeted analyses also uncovered a change in the primary auditory cortex, the brain region that processes sound. Even though the task only involved touch on the arm, autistic youth showed reduced auditory cortex activity during Reappraise compared to React, whereas typically developing youth did not. The authors suggest that adopting an objective mindset may have helped autistic youth filter out the loud mechanical noise of the MRI scanner itself.

    The researchers next looked at frontal brain regions involved in self-regulation, starting with the dorsomedial prefrontal cortex toward the upper-middle front of the brain. Typically developing youth showed increased activity in the dorsomedial prefrontal cortex and language-processing areas during reappraisal, whereas the autistic group as a whole did not show a statistically significant increase in frontal regions on its own. Across all participants combined, an increase in dorsomedial prefrontal cortex activity during reappraisal fell just short of statistical significance, and the two groups did not differ significantly from each other in this region.

    A second regulatory region, the orbitofrontal cortex located just above the eye sockets, was active across both groups, particularly on the left side. The authors note that this left-sided pattern could reflect either the left hemisphere’s role in putting experiences into words or the fact that the textures were rubbed on the left arm. In the right orbitofrontal cortex, however, autistic youth showed a steeper drop in activity during reappraisal than typically developing peers, which the authors suggest may reflect an efficient suppression of the right side to prioritize left-sided regulation.

    Within the autistic group, brain responses varied with the severity of a child’s everyday sensory symptoms, even after accounting for anxiety. Autistic youth with milder sensory over-responsivity showed larger reductions in sensory cortex activity during reappraisal, whereas those with more severe symptoms showed smaller reductions in sensory regions alongside greater increases in frontal control areas. The authors suggest that youth who are most sensitive to sensory input may have to exert greater mental effort to reappraise without an immediate reduction in sensory cortex activity, and may need more practice to use the strategy efficiently, though it is also possible that reappraisal simply works better for children with milder symptoms.

    Age was not linked to the size of the reductions in sensory cortex activity among autistic youth, suggesting that reappraisal may quiet sensory regions across the ages studied. However, age did relate to other brain patterns: younger autistic children showed more activity in visual areas at the back of the brain during React, an age-related pattern that did not appear during reappraisal. Meanwhile, older autistic teens showed greater activation during reappraisal in lower frontal regions, specifically the frontal pole and orbitofrontal cortex. Because prior research shows that typically developing youth shift from using lower to upper frontal circuits as they move into adolescence, the authors note that this pattern in older autistic teens may point to a delayed maturation of the frontal regions that support sensory regulation.

    “Teaching autistic kids to use a common emotion regulation technique seems to help reduce their brain’s sensory responses to aversive sensory stimulation,” Green said. “This suggests that when they think about sensory stimuli more objectively, such as focusing on the ‘facts’ of the sensory stimulus, their brain may not respond as strongly in regions that usually process basic sensory information. In particular, older teens with autism may engage more of the prefrontal brain regions that help with emotional and behavioral regulation. This type of emotion regulation strategy could be incorporated into interventions and tested to see if it helps with sensory over-responsivity in everyday life.”

    “I was surprised that while on the whole, the group of autistic kids all reduced reactivity in sensory brain regions when using reappraisal, only the older autistic kids engaged prefrontal regulatory regions,” Green noted. “This is in contrast to the typically developing controls who, as a group, engaged prefrontal cortex, regardless of age. This is consistent with some of our prior research that autistic teens may take longer to develop sensory regulation compared to typically developing teens. However, our results suggest that reappraisal can be helpful in reducing sensory responses even for younger autistic youth who don’t engage regulatory regions as much.”

    The unchanged distress ratings in the autistic group echo a study of daily stress in autistic youth, which found that adaptive emotion regulation strategies did not buffer everyday stress and negative emotions in autistic adolescents and young adults. While that earlier work relied on daily self-reports rather than an experimental sensory task in an MRI scanner, both studies suggest that cognitive regulation strategies may be less effective at immediately easing subjective distress in autistic youth than in non-autistic peers.

    At the neural level, the results also complement a brain-imaging study of children with sensory over-responsivity, which linked heightened sensory sensitivity to weaker connectivity within outward-facing sensory networks and stronger connectivity within inward-facing control networks at rest. Although the new study measured brain activity during an active reframing task in autistic youth rather than resting connectivity in non-autistic neurodiverse children, the new findings similarly suggest that how the brain regulates sensory input differs in youth with sensory over-responsivity.

    There are a few things to keep in mind when interpreting these findings. Participants only received a brief training session before the scan, and clinical therapies typically require weeks of practice before a person notices changes in how they consciously feel. Autistic individuals also frequently experience differences in interoception, the ability to sense internal bodily signals, as well as challenges with rapidly switching between mental tasks, which the task’s 20-second alternation required. Both factors may have made it harder for participants to register subtle shifts in their moment-to-moment discomfort.

    Because many initially recruited autistic youth were excluded due to scanner movement, and the included participants had IQ scores ranging from borderline to well above average (75 to 146) and had to be able to respond verbally to instructions, the results may not generalize to autistic youth with intellectual disabilities or limited spoken language. Future studies will need to test cognitive reappraisal outside the demanding MRI environment and evaluate whether multi-week training in cognitive behavioral therapy can produce lasting relief in daily life.

    “This reappraisal task was difficult for younger kids or those with more cognitive challenges, so while it is promising as an intervention, it may be most useful for autistic individuals with cognitive and verbal skills in the average range or higher,” Green added.

    The study, “Cognitive reappraisal modulates neural responses to aversive sensory stimulation in autistic youth,” was authored by Urvi T. Shah, Karrin Evans, Megan Banchik, Apurva Chaturvedi, Sapna Ramappa, Katie Wong, Jennifer A. Silvers, and Shulamite A. Green.

    TITLE: Setting may shape psilocybin’s effects on the brain, preliminary study suggests

    A single dose of psilocybin did not produce a statistically significant overall increase in a brain marker of synapses in healthy adults one week later, according to a small study published in Translational Psychiatry. However, participants who took psilocybin in a calm room with music, rather than inside an MRI scanner, reported more intense mystical-type experiences and showed larger changes in the marker.

    Synapses are the connection points that allow nerve cells to communicate. The brain can change these connections through a process known as synaptic plasticity, which is important for learning and adaptation. Researchers have proposed that changes in plasticity may help explain why some people report lasting mood effects after psychedelic experiences. But measuring synapses in the living human brain is difficult.

    Annette Johansen of Copenhagen University Hospital and colleagues tested whether a single dose of psilocybin would increase synaptic density in the human brain. They used positron emission tomography (PET) imaging to measure SV2A, a protein found in synapses that serves as an indirect marker of synaptic density. The researchers’ earlier work had found higher SV2A levels in the brains of pigs one week after a single dose of psilocybin.

    The study included 15 healthy adults (median age 32.5 years; 5 women), each of whom received a single oral dose of psilocybin chosen to reliably produce an intense psychedelic experience. The first five participants took psilocybin while lying in an MRI scanner and completing brain imaging tasks, while the remaining ten had their session in a dedicated room while listening to a curated music playlist. Two facilitators provided psychological support in both settings.

    PET scans measured SV2A in the frontal cortex and hippocampus before dosing and again one week afterward. Participants also reported their experiences after the session and completed a questionnaire about persisting effects three months later.

    Across the whole group, the researchers did not find a statistically significant rise in SV2A. The average changes were small, around 2% to 3%, and the study stopped early after a planned interim analysis indicated it was unlikely to reach its target result. The primary finding therefore does not show that psilocybin increased the measured synaptic marker.

    In further exploratory analyses, participants in the intervention room reported more intense mystical-type experiences and more positive lasting effects at three months than those dosed in the scanner. Negative lasting effects did not differ between the groups.

    The two groups also differed in how their SV2A levels changed. The intervention-room group showed an average increase of about 5% to 6% in the frontal cortex and hippocampus, while the scanner group did not show an increase. The difference between the groups was statistically significant in the frontal cortex but not in the hippocampus, and the increase within the intervention-room group was not statistically significant on its own. More intense mystical-type experiences were associated with larger SV2A increases, but this association was also not statistically significant.

    The authors concluded: “these findings indicate that psilocybin’s neuroplastic effects are modulated by environmental context, with important implications for psychedelic-assisted therapies.” Elsewhere in the paper, however, they describe the differences in SV2A between settings as “preliminary and hypothesis-generating rather than conclusive,” given the small sample. The researchers suggest that a supportive environment may promote positive emotional experiences and a sense of safety that could facilitate changes in brain connections, while a stressful or distracting setting such as an MRI scanner may limit them.

    The findings have substantial caveats. There was no placebo group, and participants were not randomly assigned to the two settings; the five scanner participants were simply the first five enrolled. The scanner group was very small, and the two settings differed in many ways at once, including the noise and confinement of the scanner, the imaging tasks, and the music.

    The study also included healthy adults rather than people receiving psilocybin as a treatment, and the authors note that effects might be larger in people with depression, who tend to have lower SV2A levels. Previous studies have found that SV2A measurements tend to be lower on a second scan, which could mean the study underestimated any increase. One author’s salary was supported by COMPASS Pathways, a company developing psilocybin therapy, and two other authors have ties to companies developing psychedelic drugs.
