A computer algorithm can recognize human emotions with high accuracy, transferring players' emotions to avatars or communicating with other players. The emotion detector system uses mathematical processing to analyze eyebrow position, eye openness, and mouth shape to correlate with basic human emotions.
A new machine learning algorithm can identify human facial expressions based on neural activity, with a 60% success rate. The area of the brain responsible for this task is the posterior superior temporal sulcus (pSTS), which activates when looking at images of different facial expressions.
A study published in Cognition reveals that a specific facial expression, known as the 'not face', is universally interpreted as a symbol of negative emotion across languages. The researchers found that this expression is identical across native speakers of English, Spanish, Mandarin Chinese, and American Sign Language.
A study found that individuals with right- or left-sided facial hemiparesis have difficulty interpreting emotions, particularly when the expression starts on the paralyzed side. Facial mimicry, which helps understand emotions, is also affected by asymmetry, suggesting a lateralized and anatomical basis for this phenomenon.
Research reveals that humans mirror others' faces to recognize and share emotions. This phenomenon is linked to social disorders like autism, where facial expression recognition can be impaired. Understanding sensorimotor simulation may help treat related conditions.
Researchers found that horses looked more with their left eye when viewing angry faces and showed a quicker increase in heart rate, indicating they had a functionally relevant understanding of the emotions. This ability to read human emotions may serve as a warning system, allowing horses to anticipate negative behavior.
A recent study from the University of Helsinki reveals that dogs systematically view facial expressions like humans, prioritizing eyes and altering their behavior in threatening situations. This research supports Darwin's theory on shared evolutionary roots for animal emotions.
A study using fMRI found that individuals with ASD exhibit different neural activity patterns when viewing emotional faces compared to typically developing participants. This suggests that ASD is not a uniform condition and may be linked to differences in how the brain processes emotional stimuli.

They conducted four experiments to test this theory, finding that subjects perceived happier faces as more trustworthy and angrier faces as more untrustworthy.
A study found that chimpanzees produce the same facial expressions when laugh sounds are present or absent, suggesting flexibility in their expression. The study also showed that facial expressions and vocalizations are used differently during social play.
Researchers at Ruhr-University Bochum propose a new model for emotion recognition, suggesting that humans can directly recognize emotions through pattern recognition. Even with sparse clues, humans can identify typical emotion patterns, including physiological reactions and facial expressions.
UCI psychologists found that liberals employ positive language in speech, smile more intensely, and genuinely, whereas conservatives do not. This contradicts previous self-reports suggesting conservatives are happier than liberals.
A study by McGill researchers found that Mandarin-speakers are more likely to interpret emotions through tone of voice, whereas English-language speakers rely on facial expressions. This cultural difference is rooted in the limited eye contact and restrained facial expressions typical of East Asian cultures.

Researchers at SISSA found that re-enacting emotional expressions through facial movements enhances memory recall of corresponding emotions. This suggests motor information is encoded during storage and retrieval phases.
Researchers at SISSA found that faces displaying emotionally significant expressions can modify motor action trajectories, even when unrelated to the action. The study tested reaching movements and found that emotionally charged faces were more distracting than neutral ones.
A new study demonstrates that people with multiple sclerosis often have trouble recognizing emotions conveyed by facial expressions, and now shows similar difficulties with emotions expressed through body posture. The research suggests that this difficulty is unrelated to identifying one's own emotions, a disorder known as alexithymia.
Children with ADHD exhibit impaired brain response to angry facial expressions, whereas typically developing children show a significant hemodynamic response in both happy and angry expressions.

Researchers directly compared human and bonobo yawn contagion, finding that strong relationships matter more than species for empathic responses. Humans respond more frequently to friends and kin, while bonobos do so equally, challenging the assumption that humans are more empathetic.
Researchers found that horses rely on facial expressions, particularly eye and ear positions, to gauge attention and locate food. The study's results suggest individual facial features may be important in horse communication, contradicting earlier notions about animals with eyes to the sides of their heads.
Preliminary research found that patients with serious heart and lung conditions have a narrower range of facial expressions, particularly the ability to register surprise. This can help doctors prioritize care and avoid unnecessary tests.

Researchers at Ohio State University have developed a computational model that maps 21 distinct emotional expressions, including compound emotions like 'happily surprised' or 'sadly angry'. This breakthrough enables precise tracking of emotion in the brain and has potential applications in treating disorders such as PTSD or autism.
A Cornell University neuroscientist's study finds that human facial expressions arose from universal, adaptive reactions to environmental stimuli. The findings suggest that emotional responses influence vision at the earliest moments of visual encoding, leading to contrasting eye movements that filter our reality.
Researchers have developed an on-board emotion detector using embedded cameras to analyze drivers' facial expressions, identifying irritation and anger as risk factors for aggressive driving. The system successfully detected these emotions in most cases, paving the way for potential applications in driver safety and comfort.
A new study disputes the idea that humans experience six basic emotions universally, citing context-dependent expression recognition. Researchers found that facial expressions and vocalizations were not consistently labeled with emotion words across cultures, suggesting cultural categories may be at play.
Researchers at the University of Glasgow challenge the long-held view of six basic emotions by studying the temporal dynamics of facial expressions. They found that fear and surprise share a common signal, as do anger and disgust, suggesting only four basic emotions.
Patients with Parkinson's disease struggle to recognize emotions in facial expressions and speech prosody. After surgery for deep brain stimulation, they show difficulty recognizing disgust and sadness, but this impairment is only temporary.
Research found that older adults retain ability to make accurate judgments about others' emotions using acquired knowledge. When partners were separated, both older and younger adults were equally good at estimating how their partner was feeling.

In experiments, participants were more accurate in guessing emotions from body language alone or combined with facial expressions than from facial context alone.
Studies using new technology show that our ability to imitate facial expressions depends on learning through visual feedback. In two studies, researchers found that participants who could see their imitation attempts improved over time, while those relying solely on proprioception got worse.

Facial mimicry plays a crucial role in deciphering ambiguous smiles, establishing power dynamics, and evoking emotions. The study also highlights the neurological basis of early interactions between parents and infants with cleft lip.
Researchers found that heavy pacifier use in young children is linked to poor emotional maturity and lower perspective-taking scores. The study suggests that girls may be less affected due to societal expectations of emotional sophistication. Parents are advised to limit pacifier use to promote healthy emotional development.
Researchers studied how different types of smiling affect stress recovery, finding that Duchenne smiles had the greatest impact on reducing heart rates and improving mood. Smiling may be a simple yet effective way to cope with stressful situations.
