Distinct temporal processing of task-irrelevant emotional facial expressions.
There is an ongoing debate concerning the extent to which emotional faces automatically attract attention. Using a single-target Rapid Serial Visual Presentation (RSVP) methodology, it has been found that presentation of task-irrelevant positive or negative emotionally salient stimuli (e.g., negative scenes or erotic pictures) results in a temporary inability to process target stimuli (emotion-...
متن کاملTemporal Characteristics of Categorical Perception of Emotional Facial Expressions
Perceptual processing of emotional facial expressions occurs very quickly, even without awareness. To determine whether the fast processing of facial expressions is categorical, we studied temporal characteristics of categorical perception (CP) of facial expressions. We investigated the effect of shortening stimulus duration on participant performance with respect to identifying and discriminat...
متن کاملNeural processing of emotional valence of facial expressions
Degree of emotional valence and arousal have been shown to covary with blood oxygen level dependent (BOLD) signal levels in several brain structures. Here we studied brain activity in 17 healthy subjects during perception of facial expressions varying in valence and arousal using functional magnetic resonance imaging (fMRI). Our results revealed correlations with the perceived valence in dorsol...
متن کاملDissimilar processing of emotional facial expressions in human and monkey temporal cortex
Emotional facial expressions play an important role in social communication across primates. Despite major progress made in our understanding of categorical information processing such as for objects and faces, little is known, however, about how the primate brain evolved to process emotional cues. In this study, we used functional magnetic resonance imaging (fMRI) to compare the processing of ...
متن کاملProcessing of emotional facial expressions in Korsakoff's syndrome.
Interpersonal contacts depend to a large extent on understanding emotional facial expressions of others. Several neurological conditions may affect proficiency in emotional expression recognition. It has been shown that chronic alcoholics are impaired in labelling emotional expressions. More specifically, they mislabel sad expressions, regarding them as more hostile. Surprisingly, there has bee...
