Abnormal visual representations associated with confusion of perceived facial expression in schizophrenia with social anxiety disorder.

ABSTRACT: Deficits in social functioning are especially severe amongst schizophrenia individuals with the prevalent comorbidity of social anxiety disorder (SZ&SAD). Yet, the mechanisms underlying the recognition of facial expression of emotions-a hallmark of social cognition-are practically unexplored in SZ&SAD.
