-------------------------------------------------TITLE: Faces and bodies send matching signals of attractiveness, but voices tell a different story
People often judge a potential partner based on a combination of their face, body, and voice. A recent study reveals that while facial and bodily attractiveness tend to match up, a person’s voice provides an independent cue about their traits. These findings, published in Evolution and Human Behavior, suggest that our physical features send a mix of redundant and distinct messages to observers.
Evolutionary psychology proposes that human physical traits communicate genetic quality and health to potential mates or rivals. During the search for a partner, individuals evaluate physical attractiveness to gauge underlying fitness. During competition with rivals, individuals might assess physical dominance to determine formidability. Researchers study how these visual and vocal cues combine to form an overall impression of an individual.
One major theoretical framework is the “one ornament hypothesis.” This concept suggests that different physical traits, such as the face and body, are shaped by the same underlying biological factors. In this view, various body parts act as a single, unified signal of health or genetic fitness. If a person has robust immune function or developmental stability, it should reflect across their entire physical appearance.
The second major framework is the “multiple messages hypothesis.” This theory argues that different parts of the body convey entirely separate pieces of information. For example, a face might signal immune system strength, while a voice might indicate physical dominance. If this theory holds true, a person’s individual physical features would not necessarily correlate with one another in the eyes of an observer.
Researchers also suspect that sex hormones like testosterone and estradiol might drive the synchronized development of these physical traits. These hormones guide sexual dimorphism, which refers to the biological differences in physical characteristics between men and women. Higher testosterone in men and higher estradiol in women are thought to influence the development of traits that others perceive as attractive, healthy, or dominant.
To test these competing hypotheses, a research team led by Tobias L. Kordsmeyer of the University of Goettingen designed an experiment. They wanted to examine how independent raters perceived the attractiveness, health, and physical dominance of faces, bodies, and voices. The researchers also sought to test whether sex hormones act as a biological bridge linking these disparate features.
The study included 165 men and 155 women as evaluation targets. The research team collected standardized facial photographs, three-dimensional body scans, and short audio recordings from each participant. The facial photographs featured participants standing against a white wall with a neutral expression.
The three-dimensional body scans were rendered as digital figures that rotated over an eight-second duration. The researchers deliberately removed skin color and texture from these digital models, converting them to a uniform gray. This step ensured that raters would focus entirely on physical shape and proportions, removing skin quality as a potential confounding factor.
To collect voice samples, male participants were recorded speaking about positive aspects of their lives for one minute. Female participants were recorded reading a standardized text known as the rainbow passage. The researchers extracted five-second audio clips from the men’s recordings and used the second sentence of the passage (about 3.5 seconds on average) from the women’s recordings for the final evaluation.
A separate group of 400 independent raters evaluated the collected stimuli. To prevent their judgments of one trait from influencing another, the raters were divided into specific groups. A single rater only evaluated one type of stimulus, such as male faces, female bodies, or male voices. The raters scored the targets for attractiveness, health, and physical dominance using standardized rating scales.
The research team also gathered saliva and hair samples from the targets to measure hormone levels. They measured baseline testosterone and reactive testosterone in men. Reactive testosterone was captured shortly after the men engaged in a competitive task. For women, the researchers assessed baseline testosterone and estradiol levels across different phases of the menstrual cycle.
When analyzing the rating data, the researchers found positive correlations between how raters perceived faces and bodies. Targets whose faces were rated highly for attractiveness and health also tended to receive high ratings for their body shapes. The effects were of medium size, showing a consistent pattern across both male and female targets.
This pattern also held true for physical dominance, though it was only observed for male targets. Men with faces rated as physically dominant also had bodies rated as physically dominant. Female targets did not exhibit a coordinated rating for physical dominance between their faces and bodies.
These positive associations between the face and the body align with the one ornament hypothesis. Observers seem to interpret facial and bodily cues redundantly, picking up on shared information about the individual’s physical condition. Even without skin texture, the bodies provided enough shape information to align with the health and attractiveness ratings of the faces.
The results for vocal recordings painted a different picture. The researchers found very few measurable associations between how raters judged a target’s voice and how they judged the target’s face or body. Voice ratings appeared to operate independently from visual appearance.
An individual might possess a highly rated face or body, but this did not guarantee their voice would be perceived in the same way. This independence supports the multiple messages hypothesis. The human voice seems to act as a separate channel of communication, offering non-redundant information to observers rather than echoing visual cues.
The hormone analysis yielded unexpected results. The researchers found that adult hormone levels did not mediate the correlated perceptions of faces and bodies. While men’s baseline testosterone levels did show some positive associations with facial dominance and vocal attractiveness, the hormones did not serve as the underlying link for synchronized ratings across body parts.
The proposed mechanism of adult sex hormones bridging these distinct traits was not supported by the data. Adjusting for the targets’ body mass index or relationship status did not alter these outcomes. The correlations between traits remained robust even when accounting for body fat.
The study measured adult baseline and reactive hormone levels rather than developmental hormones. Physical traits like bone structure and vocal cord length are heavily shaped by organizational hormones during fetal development and puberty. Adult hormone levels might not accurately reflect the specific hormonal environment that originally sculpted these physical characteristics.
Additionally, the body scans lacked skin color and texture. Skin quality is a known biological indicator of physical health. Stripping this information away might have altered how raters evaluated the overall condition of the targets, even though it successfully isolated the role of physical shape.
The researchers measured subjective impressions of health, dominance, and attractiveness rather than objective medical data. The ratings reveal how people perceive others based on evolutionary psychological cues. They do not confirm whether the highly rated individuals were objectively healthier or physically stronger in reality.
Future investigations could incorporate developmental hormone tracking during adolescence to better understand how biology links physical traits. Researchers might also include other sensory cues, such as body odor or dynamic movement, to build a more comprehensive picture of human nonverbal signaling.
The study, “Correlated perceptions and underlying hormonal factors of bodily, facial, and vocal attractiveness, health, and physical dominance,” was authored by Tobias L. Kordsmeyer, Philine A.C. Rasokat, Julia Stern, Christoph Schild, and Lars Penke.

-------------------------------------------------TITLE: People with higher autistic traits tend to avoid positive relationship-maintenance tactics
A recent study suggests that people in the general population who possess higher levels of autistic-like traits tend to avoid positive, affectionate behaviors to maintain their romantic relationships. The research, published in Evolutionary Psychology, indicates that these traits influence relationship dynamics largely through a person’s attachment style rather than broad evolutionary reproductive strategies.
The research was led by Andrzej Łukasik, a PhD with habilitation and head of the Department of Psychology at the University of Rzeszow’s Collegium Medicum in Poland, who aimed to explore how subtle personality traits shape romantic behavior from an evolutionary perspective. The central focus of the study is autistic-like traits, which refer to patterns of social functioning, communication difficulties, and rigid thinking. “Autistic-like traits (ALTs) are personality, social, and cognitive characteristics associated with autism that can also occur, to varying degrees, in the general population,” Łukasik told PsyPost. “They are not considered a disorder.”
To understand how these traits impact relationships, the scientists looked at mate retention tactics. These are behaviors people use to keep a partner and prevent them from leaving. Mate retention is generally divided into what Łukasik described as “benefit-provisioning tactics, such as showing affection, giving compliments or gifts, and offering support, and cost-inflicting tactics, such as inducing jealousy, engaging in controlling behavior, or making threats.” The authors suspected that the way a person tries to keep a partner depends heavily on their attachment style.
Attachment styles describe how people form emotional bonds, generally falling into secure, anxious, or avoidant categories. “People with anxious attachment usually have a strong need for closeness and may react strongly to distance or uncertainty,” Łukasik explained. “In contrast, people with avoidant attachment may feel uncomfortable with emotional closeness and place greater value on independence.” In fact, a 2016 study found that insecure attachment predicts how frequently people use various mate retention behaviors, and a study covered by PsyPost in 2021 indicated that anxious attachment is linked to both positive and negative mate retention strategies.
The researchers also framed their study around life history theory, an evolutionary concept describing how individuals allocate their limited time and energy. In this framework, people adopt varying reproductive strategies. A fast strategy involves high mating effort, characterized by seeking multiple partners and short-term relationships. A slow strategy involves high parental effort, prioritizing stable, long-term investments in a single partner and offspring.
Previous evolutionary theories proposed that autistic-like traits might be an adaptation linked to a slow reproductive strategy. However, because these traits are also associated with insecure attachment, which typically aligns with a fast strategy, the authors designed this study to test how all these factors connect. “Research by Marco Del Giudice and colleagues (2010) has suggested that ALTs may be associated with a slow reproductive strategy,” Łukasik noted. “However, higher levels of ALTs are also linked to insecure attachment styles (avoidant and anxious), which have more often been associated with characteristics of a fast strategy.”
Therefore, the researchers examined whether ALTs might actually predict a fast strategy and whether attachment style moderates that relationship. To map out these connections, the scientists recruited 796 Polish adults. The participants were 52 percent female and had an average age of 36.4 years. Every participant had been in a romantic relationship for at least three months.
The researchers administered a series of established questionnaires. They used the Autism-Spectrum Quotient to measure the degree of autistic-like traits, the Experiences in Close Relationships scale to assess anxious and avoidant attachment, and the Mate Retention Inventory to evaluate the frequency of benefit-provisioning and cost-inflicting behaviors. They also used brief scales to measure mating effort and parental effort. The team then used a statistical technique called structural equation modeling to analyze the complex web of relationships between all these variables at once.
The results suggest that autistic-like traits are notable predictors of insecure attachment. Participants who scored higher on autistic-like traits reported higher levels of both anxious and avoidant attachment styles. This indicates that people with more of these traits often worry about their partners leaving while simultaneously struggling with emotional closeness.
When looking at mate retention, the researchers found that individuals with higher autistic-like traits were less likely to engage in benefit-provisioning tactics. They tended to avoid showering their partners with affection or gifts as a way to maintain the relationship. The initial statistical models suggested that these individuals were also less likely to use cost-inflicting tactics. However, when the scientists controlled for the participants’ ages, they found a positive link between autistic-like traits and cost-inflicting tactics.
Age acted as a masking variable because older individuals naturally tend to use fewer negative tactics. Once age was factored out, the data suggested that people with higher autistic-like traits might actually use cost-inflicting tactics slightly more often.
In terms of evolutionary strategies, autistic-like traits proved to be weak predictors of life history outcomes. “The results did not support the hypothesis that ALTs predict a fast rather than a slow reproductive strategy,” Łukasik said. “ALTs were only weakly related to reproductive strategies.” Instead, attachment styles acted as a bridge between the variables.
Anxious attachment was linked to higher mating effort and lower parental effort, and it predicted the use of both positive and negative mate retention tactics. Avoidant attachment was similarly linked to higher mating effort and lower parental effort, but it predicted a lower use of benefit-provisioning tactics. “Individuals with an anxious attachment style tend to use a mixed partner-retention strategy involving both attraction and distancing, probably due to an overperception of the risk of infidelity,” Łukasik pointed out. “In contrast, individuals with an avoidant attachment style tend to use benefit-provisioning tactics less often, possibly because such tactics allow them to avoid closeness with their partner and maintain distance from their partner.”
Age played a broad role across the entire study. The scientists found that as participants got older, their levels of attachment anxiety decreased. Older participants also reported lower mating effort, higher parental effort, and a decreased use of both types of mate retention tactics. This aligns with the idea that as people age and relationships stabilize, they shift their energy away from securing a mate and toward investing in their existing family.
As with all research, there are a few things to keep in mind. The study relied on cross-sectional data, meaning the researchers measured all variables at a single point in time. This design makes it impossible to determine the true direction of the effects, and one cannot assume that autistic-like traits cause specific attachment styles or relationship behaviors. In addition, the participants self-reported their behaviors, which can introduce bias if people alter their answers to appear more socially acceptable.
The researchers also note that the Autism-Spectrum Quotient might measure elements of social anxiety or general interpersonal difficulty rather than pure autistic traits. This overlap could skew the interpretation of the results. The weak link between autistic-like traits and reproductive strategies also suggests that broad evolutionary models like life history theory might not fully capture the nuances of modern human relationships, pointing to a need for different measurement approaches in future studies.
Ultimately, the findings offer insight into the practical challenges some people face in romance. “These findings may help explain relationship difficulties experienced by individuals with higher levels of autistic-like traits,” Łukasik concluded. “Benefit-provisioning tactics are generally associated with greater relationship satisfaction, whereas cost-inflicting tactics are linked to lower satisfaction and may contribute to difficulties in developing and maintaining stable close relationships.”
The study, “Autistic-Like Traits in Members of the General Population and Mate Retention Tactics: The Mediation of Attachment Styles and Reproductive Strategies,” was authored by Andrzej Łukasik and Agnieszka Łaba-Hornecka.

They tended to avoid showering their partners with affection or gifts as a way to maintain the relationship. The initial statistical models suggested that these individuals were also less likely to use cost-inflicting tactics. However, when the scientists controlled for the participants’ ages, they found a positive link between autistic-like traits and cost-inflicting tactics.
Age acted as a masking variable because older individuals naturally tend to use fewer negative tactics. Once age was factored out, the data suggested that people with higher autistic-like traits might actually use cost-inflicting tactics slightly more often.
In terms of evolutionary strategies, autistic-like traits proved to be weak predictors of life history outcomes. “The results did not support the hypothesis that ALTs predict a fast rather than a slow reproductive strategy,” Łukasik said. “ALTs were only weakly related to reproductive strategies.” Instead, attachment styles acted as a bridge between the variables.
Anxious attachment was linked to higher mating effort and lower parental effort, and it predicted the use of both positive and negative mate retention tactics. Avoidant attachment was similarly linked to higher mating effort and lower parental effort, but it predicted a lower use of benefit-provisioning tactics. “Individuals with an anxious attachment style tend to use a mixed partner-retention strategy involving both attraction and distancing, probably due to an overperception of the risk of infidelity,” Łukasik pointed out. “In contrast, individuals with an avoidant attachment style tend to use benefit-provisioning tactics less often, possibly because such tactics allow them to avoid closeness with their partner and maintain distance from their partner.”
Age played a broad role across the entire study. The scientists found that as participants got older, their levels of attachment anxiety decreased. Older participants also reported lower mating effort, higher parental effort, and a decreased use of both types of mate retention tactics. This aligns with the idea that as people age and relationships stabilize, they shift their energy away from securing a mate and toward investing in their existing family.
As with all research, there are a few things to keep in mind. The study relied on cross-sectional data, meaning the researchers measured all variables at a single point in time. This design makes it impossible to determine the true direction of the effects, and one cannot assume that autistic-like traits cause specific attachment styles or relationship behaviors. In addition, the participants self-reported their behaviors, which can introduce bias if people alter their answers to appear more socially acceptable.
The researchers also note that the Autism-Spectrum Quotient might measure elements of social anxiety or general interpersonal difficulty rather than pure autistic traits. This overlap could skew the interpretation of the results. The weak link between autistic-like traits and reproductive strategies also suggests that broad evolutionary models like life history theory might not fully capture the nuances of modern human relationships, pointing to a need for different measurement approaches in future studies.
Ultimately, the findings offer insight into the practical challenges some people face in romance. “These findings may help explain relationship difficulties experienced by individuals with higher levels of autistic-like traits,” Łukasik concluded. “Benefit-provisioning tactics are generally associated with greater relationship satisfaction, whereas cost-inflicting tactics are linked to lower satisfaction and may contribute to difficulties in developing and maintaining stable close relationships.”

-------------------------------------------------TITLE: People with higher autistic traits tend to avoid positive relationship-maintenance tactics
A recent study suggests that people in the general population who possess higher levels of autistic-like traits tend to avoid positive, affectionate behaviors to maintain their romantic relationships. The research, published in Evolutionary Psychology, indicates that these traits influence relationship dynamics largely through a person’s attachment style rather than broad evolutionary reproductive strategies.
The research was led by Andrzej Łukasik, a PhD with habilitation and head of the Department of Psychology at the University of Rzeszow’s Collegium Medicum in Poland, who aimed to explore how subtle personality traits shape romantic behavior from an evolutionary perspective. The central focus of the study is autistic-like traits, which refer to patterns of social functioning, communication difficulties, and rigid thinking. “Autistic-like traits (ALTs) are personality, social, and cognitive characteristics associated with autism that can also occur, to varying degrees, in the general population,” Łukasik told PsyPost. “They are not considered a disorder.”
To understand how these traits impact relationships, the scientists looked at mate retention tactics. These are behaviors people use to keep a partner and prevent them from leaving. Mate retention is generally divided into what Łukasik described as “benefit-provisioning tactics, such as showing affection, giving compliments or gifts, and offering support, and cost-inflicting tactics, such as inducing jealousy, engaging in controlling behavior, or making threats.” The authors suspected that the way a person tries to keep a partner depends heavily on their attachment style.
Attachment styles describe how people form emotional bonds, generally falling into secure, anxious, or avoidant categories. “People with anxious attachment usually have a strong need for closeness and may react strongly to distance or uncertainty,” Łukasik explained. “In contrast, people with avoidant attachment may feel uncomfortable with emotional closeness and place greater value on independence.” In fact, a 2016 study found that insecure attachment predicts how frequently people use various mate retention behaviors, and a study covered by PsyPost in 2021 indicated that anxious attachment is linked to both positive and negative mate retention strategies.
The researchers also framed their study around life history theory, an evolutionary concept describing how individuals allocate their limited time and energy. In this framework, people adopt varying reproductive strategies. A fast strategy involves high mating effort, characterized by seeking multiple partners and short-term relationships. A slow strategy involves high parental effort, prioritizing stable, long-term investments in a single partner and offspring.
Previous evolutionary theories proposed that autistic-like traits might be an adaptation linked to a slow reproductive strategy. However, because these traits are also associated with insecure attachment, which typically aligns with a fast strategy, the authors designed this study to test how all these factors connect. “Research by Marco Del Giudice and colleagues (2010) has suggested that ALTs may be associated with a slow reproductive strategy,” Łukasik noted. “However, higher levels of ALTs are also linked to insecure attachment styles (avoidant and anxious), which have more often been associated with characteristics of a fast strategy.”
Therefore, the researchers examined whether ALTs might actually predict a fast strategy and whether attachment style moderates that relationship. To map out these connections, the scientists recruited 796 Polish adults. The participants were 52 percent female and had an average age of 36.4 years. Every participant had been in a romantic relationship for at least three months.
The researchers administered a series of established questionnaires. They used the Autism-Spectrum Quotient to measure the degree of autistic-like traits, the Experiences in Close Relationships scale to assess anxious and avoidant attachment, and the Mate Retention Inventory to evaluate the frequency of benefit-provisioning and cost-inflicting behaviors. They also used brief scales to measure mating effort and parental effort. The team then used a statistical technique called structural equation modeling to analyze the complex web of relationships between all these variables at once.
The results suggest that autistic-like traits are notable predictors of insecure attachment. Participants who scored higher on autistic-like traits reported higher levels of both anxious and avoidant attachment styles. This indicates that people with more of these traits often worry about their partners leaving while simultaneously struggling with emotional closeness.
When looking at mate retention, the researchers found that individuals with higher autistic-like traits were less likely to engage in benefit-provisioning tactics. They tended to avoid showering their partners with affection or gifts as a way to maintain the relationship. The initial statistical models suggested that these individuals were also less likely to use cost-inflicting tactics. However, when the scientists controlled for the participants’ ages, they found a positive link between autistic-like traits and cost-inflicting tactics.
Age acted as a masking variable because older individuals naturally tend to use fewer negative tactics. Once age was factored out, the data suggested that people with higher autistic-like traits might actually use cost-inflicting tactics slightly more often.
