When people read a poem strictly for its beauty, their brains undergo a distinct three-step process that separates emotional resonance from basic reading comprehension. Researchers mapping brain activity found that readers temporarily quiet down the language-processing centers of their brains to fully immerse themselves in the imagery and emotion of the text. The findings were published in the journal NeuroImage.
In education and literature, scholars often divide reading into two distinct categories. The first is efferent reading, which happens when someone reads to extract facts, analyze writing techniques, or gather objective information. The second is aesthetic reading, which involves connecting with a text on a personal, emotional, or imaginative level.
When a student reads a biology textbook, they are likely practicing efferent reading. When that same student reads a moving novel and feels a sense of empathy for the characters, they have transitioned into an aesthetic reading stance. Educational theories suggest that genuine aesthetic reading requires the reader to go beyond the literal meaning of the words.
The aesthetic process starts with understanding the external language of the text. Eventually, the reader must move inward, using their own memories and emotional responses to appreciate the work. The exact biological mechanisms behind this transition from literal understanding to deep emotional resonance have remained a mystery.
Researchers Huishu Liu from South China Normal University and Xiaomeng Xu from Tsinghua University led a small study to observe this transition physically inside the brain. Along with colleagues Wanyan Sun, Dan Zhang, and Yu Zhang, they wanted to track the exact moments when a reader shifts from merely decoding text to experiencing internal resonance.
To do this, the research team used a technology called functional near-infrared spectroscopy, commonly referred to as fNIRS. This device looks like a swimming cap studded with small sensors and wires, and participants securely wear it on their heads during the experiment. The sensors beam harmless near-infrared light through the skull to measure changes in blood flow on the surface of the brain. The technology tracks light absorption to calculate chemical concentrations in real time.
When a specific part of the brain is working hard, it requires more oxygen. The fNIRS cap measures oxygenated hemoglobin, the molecule that carries oxygen in the blood, to show which brain regions are currently active. While this tool does not scan deep into the brain, it allows participants to sit comfortably at a computer and undergo natural reading tasks.
The research team recruited 35 university students in Beijing to participate in the experiment. Because this sample size is less than 50, it is considered a small study. The participants represented a balanced mix of academic fields, including engineering, the sciences, and the humanities.
For the reading material, the team selected twenty classical Chinese poems. Specifically, they chose five-character regulated verses from the Tang Dynasty. These poems are well known for evoking strong imagery, and each contains exactly forty written characters. Native readers can typically skim a poem of this length in five to eight seconds.
During the experiment, the participants sat in front of a computer screen while wearing the fNIRS equipment. For some poems, the researchers instructed the students to engage in efferent reading. They were told to focus on the structure of the poem, the historical facts, and the literary techniques.
For other poems, the instructions prompted the students to read aesthetically. The prompt asked them to allow themselves to feel the emotion of the piece and imagine the scenery described. Each poem remained on the screen for fifty seconds. After every reading round, the students answered questions about their mental stance, how familiar they were with the poem, and how much they liked it.
The brain scans revealed a unique timeline of activity during the aesthetic reading tasks. The researchers observed a distinct three-phase pattern that did not occur when participants were reading just for facts. To calculate these brain changes, the software compared the blood flow during the reading task to a baseline resting state. The early seconds of the process were nearly identical across both reading conditions.
In the first ten seconds of reading, blood flow increased in several sections of the left temporal lobe, an area situated near the ear. These brain sections, which include the left superior, middle, and inferior temporal gyri, manage word processing and basic language comprehension. The left primary somatosensory cortex, which helps process sensory information, also showed heightened oxygen levels. At this early stage, the participants were simply taking in the words and figuring out what the poem literally said.
The second phase occurred from the ten-second mark up to the thirty-second mark. During this window, readers in the aesthetic group exhibited a surprising drop in oxygenated blood flow within those same temporal lobe regions. The researchers labeled this phenomenon semantic inhibition.
Essentially, the brain appeared to mute its own language-processing centers. The readers momentarily stopped analyzing the literal meaning of the vocabulary. In contrast, the students who were reading for cold facts maintained high levels of activity in these language centers throughout the entire window.
The third phase unfolded during the final twenty seconds of the reading task. The temporal lobe regions became highly active again in the aesthetic readers. At the exact same time, a new area near the top-front of the head flooded with oxygen-rich blood.
This frontal area is known as the left dorsolateral prefrontal cortex. Neuroscientists associate this specific brain region with pulling up personal memories, generating mental images, and feeling empathy. The late surge of activity suggests that the participants were actively connecting the meaning of the poem to their own internal feelings and life experiences.
The researchers also noted a relationship between the magnitude of these blood flow changes and the subjective experiences of the readers. Students who experienced the largest dip in language processing followed by the sharpest rebound were the ones who reported the highest levels of aesthetic appreciation.
The study authors pointed out that this progression mirrors ancient philosophical ideas about art and truth. In Taoism, classical thinkers often described language as a temporary ladder or pathway. Once a person grasps the deeper truth of a concept, they are supposed to discard the words used to convey it.
A similar dynamic seems to unfold on a biological level during poetry reading. The brain relies on language centers to decode the initial text. Once the basic meaning is firmly established, the brain suppresses that literal analysis, making room for imagination and emotional resonance to take over.
The findings also reflect ideas proposed by philosopher Friedrich Schiller, who argued that humanity is caught between cold rationality and boundless emotion. Schiller believed that true aesthetic appreciation acts as a bridge, bringing reason and sensation into harmony. This three-stage brain response physically demonstrates that harmony, balancing the rational processing of vocabulary with the emotional experience of the arts.
While these brain activity maps are highly detailed, the authors noted a few caveats. The technology used in the experiment measures blood flow only on the surface of the cortex, meaning deeper brain structures involved in emotion and memory were not visible as part of this process.
Additionally, an apparent drop in oxygenated blood flow does not unconditionally prove that the brain is actively suppressing a function. The participants might have simply shifted their attention away from the text for a few seconds. The differences in activation might not be statistically significant enough across larger populations to establish an absolute biological rule.
Future research with wider demographic groups and higher-resolution brain scanners might clarify the exact nature of this middle phase. Scientists could also apply these scanning methods to different forms of art, such as listening to music or examining a painting.
Educational practices often prioritize syntax, vocabulary testing, and strict textual analysis over emotional engagement. The authors hope these early insights will encourage educators to give students the mental space to step away from literal definitions. By momentarily letting go of the words, readers might discover the deeper beauty of literature.
The study, “Neural Dynamics of Aesthetic Appreciation: fNIRS Evidence from Poetry Reading,” was authored by Huishu Liu, Xiaomeng Xu, Wanyan Sun, Dan Zhang, and Yu Zhang.

-------------------------------------------------TITLE: Short-video viewing temporarily shuts down cognitive control networks, study finds
Watching preferred short videos may temporarily quiet brain regions involved in self-control and monitoring, and this effect could be linked to levels of the brain chemical glutamate. This research was published in NeuroImage.
Short-video platforms are built around quick, engaging clips that users can continue or skip within seconds. These platforms can be entertaining and harmless for many people, but researchers have become increasingly interested in why some users find them difficult to stop using. One possible explanation is that immersive, pleasurable viewing may reduce the need for active monitoring and self-control.
The new study focused on two brain regions: the dorsal anterior cingulate cortex and the dorsolateral prefrontal cortex. The dorsal anterior cingulate cortex helps detect conflict, monitor behavior, and decide when more mental effort is needed. The dorsolateral prefrontal cortex is involved in applying control, such as staying focused or resisting distraction. Together, these areas help people regulate behavior in situations where attention and self-control are required.
The researchers also examined two brain chemicals. Glutamate is the brain’s main excitatory neurotransmitter, meaning it helps increase neural activity. Gamma-aminobutyric acid, or GABA, is the brain’s main inhibitory neurotransmitter, meaning it helps reduce or regulate neural activity. The team wanted to know whether these chemicals, measured at rest, could help explain why people differ in how strongly their cognitive control network responds during short-video viewing.
Led by Tiantian Hong of Zhejiang University in China, the researchers recruited 66 young adults. After excluding participants because of excessive head movement or poor-quality brain chemistry scans, the final sample included 56 people with an average age of about 23 years. The sample included 19 females.
Participants first underwent proton magnetic resonance spectroscopy, a brain imaging technique used to estimate glutamate and GABA concentrations in the dorsal anterior cingulate cortex. They then completed a short-video viewing task during functional magnetic resonance imaging, which measures changes in brain activity. Participants watched two six-minute blocks of videos and could press a button to skip to the next video whenever they wanted. Videos watched to the end were treated as “liked,” while videos skipped before halfway were treated as “disliked.”
The main finding was that liked videos were associated with significant deactivation in both cognitive control regions. In other words, when participants watched videos that they allowed to continue, activity in the dorsal anterior cingulate cortex and dorsolateral prefrontal cortex fell below baseline.
Disliked videos demonstrated a different pattern. During these videos, activity in the dorsal anterior cingulate cortex did not significantly differ from baseline, while the dorsolateral prefrontal cortex was still suppressed. The visual cortex, which processes visual information, was active during both liked and disliked videos, suggesting the results were not simply because participants were looking at a screen.
Hong and colleagues also found that people with higher resting glutamate in the dorsal anterior cingulate cortex showed less suppression of both cognitive control regions during video viewing. GABA was not significantly associated with activity in these regions. The authors concluded that immersive viewing of preferred short videos deactivates the cognitive control network, and individual differences in this deactivation are linked to glutamate metabolism.
Interestingly, connectivity between the dorsal anterior cingulate cortex and dorsolateral prefrontal cortex increased during short-video viewing, especially for liked videos. The authors caution that this does not necessarily mean stronger self-control. Instead, they suggest the two regions may be jointly downregulated during preferred viewing, producing a more coordinated pattern of reduced activity.
Some limitations are to be noted. For example, the study did not assess short-video addiction or compulsive use in detail, and “liked” videos were defined by whether participants kept watching rather than by explicit post-viewing ratings. In addition, the study only recruited young adults with a predominantly male makeup, which limits the generalizability of the findings.
The study, “Brain activity inhibition during Short Video Viewing: neurochemical insights,” was authored by Tiantian Hong, Conghui Su, Hui Zhou, Fengji Geng, and Yuzheng Hu.

-------------------------------------------------TITLE: Brain signals can reveal when a person is preparing to tell a lie
URL: https://www.psypost.org/brain-signals-can-reveal-when-a-person-is-preparing-to-tell-a-lie/
Brain signals can reveal when a person is preparing to lie, even before they say a single word. A recent study published in the journal NeuroImage explores how the brain readies itself to tell a falsehood. The findings suggest that just anticipating a lie requires a distinct mental effort that sensors can detect.
The science of lie detection has a long and troubled history. Traditional methods like the polygraph, which measures physical signs of stress, have been widely criticized for their unreliability. In recent years, researchers have increasingly turned to brain imaging techniques in search of more objective indicators of deception.
Most of this previous work has focused on brain activity that occurs during the act of lying itself. However, in everyday situations, people are often given subtle warning signs before they lie. A question begins, prompting the brain to prepare a deceptive response before any words are spoken. This preparatory stage has received relatively little scientific attention.
The researchers set out to determine whether preparing to lie leaves identifiable traces in brain activity. They wanted to know whether these signals could eventually contribute to new approaches to deception detection. The team also sought to create a more realistic experimental scenario than many previous studies by examining lies about personal information rather than arbitrary topics like furniture.
Led by Emely Voltz from the University of Bonn, the research team recruited 32 participants for the experiment. Participants wore a cap fitted with sensors that recorded their brain’s electrical activity while they completed a deception task. They were shown cue words such as “origin” or “address” that signaled the category of an upcoming personal question.
Each participant was assigned one category about which they were instructed to lie, while answering truthfully for all others. For example, a participant assigned the category “origin” might see the statement “Birth country = Germany?” and be required to answer “yes” even if the statement was false. The cue appeared two and a half seconds before the question, providing time to prepare a deceptive response. Across two blocks of trials, a quarter of the prompts required lying and the rest required truth-telling.
The researchers found that cues signaling an upcoming lie produced clear and measurable differences in brain activity before the question appeared. Several neural markers associated with attention and preparation became more pronounced following lie cues. Brain signals linked to shifting attention, deeper cognitive processing, and anticipating an event all increased.
At the same time, alpha power, a pattern of brain activity often associated with a neural idle state, decreased. This drop suggests that the brain was mobilizing cognitive resources to handle the greater mental demands of deception. The authors concluded that these findings demonstrate “enhanced mobilization of cognitive resources in the period leading up to deception,” highlighting the potential benefit of studying the preparation phase rather than just the act of lying.
The team also investigated whether these neural signals could identify which category of personal information each participant had been assigned to lie about. Using a combination of the three most informative measures, the researchers correctly identified the lie category for 24 of the 32 participants. Seven cases were inconclusive, and the system made only one incorrect classification. This suggests that the preparatory brain signals contained meaningful information that could support future lie-detection approaches.
Several limitations should be considered when interpreting these findings. For example, participants were instructed when to lie rather than choosing to deceive spontaneously. This setup makes the task less representative of real-world deception, where people decide for themselves whether to tell the truth.
The paper, “(Don’t) take it personally: EEG markers of preparing lies about autobiographical questions,” was authored by Emely Voltz, Jonas Schmuck, Robert Schnuerch, and Henning Gibbons.

Brain signals can reveal when a person is preparing to lie, even before they say a single word. A recent study published in the journal NeuroImage explores how the brain readies itself to tell a falsehood. The findings suggest that just anticipating a lie requires a distinct mental effort that sensors can detect.
The science of lie detection has a long and troubled history. Traditional methods like the polygraph, which measures physical signs of stress, have been widely criticized for their unreliability. In recent years, researchers have increasingly turned to brain imaging techniques in search of more objective indicators of deception.
Most of this previous work has focused on brain activity that occurs during the act of lying itself. However, in everyday situations, people are often given subtle warning signs before they lie. A question begins, prompting the brain to prepare a deceptive response before any words are spoken. This preparatory stage has received relatively little scientific attention.
The researchers set out to determine whether preparing to lie leaves identifiable traces in brain activity. They wanted to know whether these signals could eventually contribute to new approaches to deception detection. The team also sought to create a more realistic experimental scenario than many previous studies by examining lies about personal information rather than arbitrary topics like furniture.
Led by Emely Voltz from the University of Bonn, the research team recruited 32 participants for the experiment. Participants wore a cap fitted with sensors that recorded their brain’s electrical activity while they completed a deception task. They were shown cue words such as “origin” or “address” that signaled the category of an upcoming personal question.
Each participant was assigned one category about which they were instructed to lie, while answering truthfully for all others. For example, a participant assigned the category “origin” might see the statement “Birth country = Germany?” and be required to answer “yes” even if the statement was false. The cue appeared two and a half seconds before the question, providing time to prepare a deceptive response. Across two blocks of trials, a quarter of the prompts required lying and the rest required truth-telling.
The researchers found that cues signaling an upcoming lie produced clear and measurable differences in brain activity before the question appeared. Several neural markers associated with attention and preparation became more pronounced following lie cues. Brain signals linked to shifting attention, deeper cognitive processing, and anticipating an event all increased.
At the same time, alpha power, a pattern of brain activity often associated with a neural idle state, decreased. This drop suggests that the brain was mobilizing cognitive resources to handle the greater mental demands of deception. The authors concluded that these findings demonstrate “enhanced mobilization of cognitive resources in the period leading up to deception,” highlighting the potential benefit of studying the preparation phase rather than just the act of lying.
The team also investigated whether these neural signals could identify which category of personal information each participant had been assigned to lie about. Using a combination of the three most informative measures, the researchers correctly identified the lie category for 24 of the 32 participants. Seven cases were inconclusive, and the system made only one incorrect classification. This suggests that the preparatory brain signals contained meaningful information that could support future lie-detection approaches.
Several limitations should be considered when interpreting these findings. For example, participants were instructed when to lie rather than choosing to deceive spontaneously. This setup makes the task less representative of real-world deception, where people decide for themselves whether to tell the truth.
