A study published in PLOS Medicine found that changes in brain activity correlated with clinical pain scores, but were more strongly linked to behavioral components such as facial expression than physiological components like heart rate. The...
A study found that variations in eyebrow shape, eyelid position, and wrinkles impact perceived facial expressions and mood. Drooping of the upper eyelid was a key indicator of tiredness, while altering eyebrows and forehead wrinkles changed perceptions of anger and happiness.
A computer system called SEMAINE is being developed to recognize human emotions through facial expressions, gaze, and voice, enabling it to adapt its performance and engage in conversation. This project aims to bridge the gap between humans and technology, paving the way for more natural interactions.
Researchers used fMRI to study two emotion regulation techniques: cognitive reappraisal and expressive suppression. Cognitive reappraisal reduced negative emotions by reinterpretating the meaning of disgusting images, while expressive suppression increased neural activity in the amygdala and insula.
Research reveals that Japanese participants are more influenced by background figures' emotions when judging a person's feelings, while North Americans focus on the individual's facial expression. This difference is attributed to cultural differences in attention patterns and social practices.
A Northwestern University study found that electrical activity in the brain is altered within 200 milliseconds when viewing subliminal emotional expressions, leading to biased ratings of facial expressions. Those with anxiety tend to exhibit stronger brain responses to fear-primed expressions.
Autistic individuals often struggle with interpreting subtle social cues like facial expressions and tone of voice. A UCLA study found that explicit instructions can train their brains to respond appropriately. Researchers trained ASD children to pay attention to these cues, resulting in increased activity in the brain's 'social' network.

The research suggests that motion reveals the temporal characteristics of emotions and improves sensitivity to communication of emotion.
A new study reveals that the amygdala actively directs gaze to eye region to process fear cues, enabling individuals with damaged amygdalae to recognize fear in facial expressions. Researchers suggest training patients to always look at eyes may rescue impaired fear recognition.
Researchers found that shy children with high shyness-BI indexes and specific genetic variations showed smaller responses to hostile and neutral facial expressions in certain brain regions. This suggests a biased pattern of processing emotional information, which can be recognized early in life.
Research suggests that subconscious bias can distort facial perceptions, leading to the perpetuation of stereotypes and racism. Studies show that even well-meaning individuals may view identical faces as more hostile in African American faces, highlighting the importance of addressing implicit bias.
A computer vision study reveals that the brain processes facial recognition and emotional expression in linked neural pathways. The researchers developed a model that explains how humans recognize familiar faces and emotions, which can be applied to create more accurate face-recognition systems.
Researchers found that alcohol increases the likelihood of aggressive behavior in individuals who tend to express their anger outwardly, such as through verbal or physical aggression. This association is significant and highlights the importance of understanding emotions and regulation in relation to drinking and aggressive behavior.
A recent study by Seth Pollak found that children who have experienced physical abuse categorize facial expressions differently than non-abused children. Abused children identified more faces as being 'angry' rather than fearful or sad. This suggests that experience can shape how people perceive and understand emotions.
Research found that autistic preschoolers have 10% larger brains than normally developing children, which may contribute to their difficulty in recognizing emotions from facial expressions. The study also suggests that early intervention programs can help rewire the brain to process faces and emotions more normally.
A study published in Neuropsychology found that pre-pubescent boys use more of their right brain to process faces and expressions, whereas girls use more of their left brain. This difference has significant implications for understanding the effects of brain injury on men and women.
Three new studies show that expressing positive emotions can lead to better relationships, mental focus, and personal well-being. Additionally, research finds that a positive outlook on life persists into old age, with extraverted individuals less likely to experience a decline in positive affect.
A study published in Nature found that individuals with aphasia, who experience language loss after a stroke or brain damage, possess an exceptional ability to detect deception. They were able to identify lies cued by facial expressions alone with high accuracy, outperforming other groups.
A study by Ulf Dimberg found that facial muscle activity can be spontaneously evoked without conscious awareness, suggesting subconscious emotional communication. The results support the theory that important aspects of face-to-face interaction can occur on a subconscious level.
