Abstract

Individuals with schizophrenia reportedly demonstrate deficits in emotion perception. Relevant studies on the effects of decoder's sex, communication channels and emotion categories have produced mixed findings and seldom explored the interactions among these three key factors. The present pilot study examined how male and female individuals with schizophrenia and healthy controls perceived emotional (e.g., angry, happy, and sad) and neutral expressions from verbal semantic and nonverbal prosodic and facial channels. Twenty-eight (11 females) individuals with schizophrenia and 30 healthy controls (13 females) were asked to recognize emotional facial expressions, emotional prosody, and emotional semantics. Both accuracy and response time showed subpar performance for all communication channels and emotional categories in the schizophrenia group. More severe emotion perception deficits were found with the nonverbal (not the verbal) materials. There was also a reduced level of impairment with anger perception, especially in the female individuals with schizophrenia while biased perception towards emotional semantics was more pronounced in male individuals with schizophrenia. These findings, although preliminary, indicate the channel- and category-specific nature of emotion perception with potential sex differences among people with schizophrenia, which has important theoretical and practical implications.
