Recognition of posed and genuine facial expressions of emotion in paranoid and nonparanoid schizophrenia

Most previous research reporting emotion-recognition deficits in schizophrenia has used posed facial expressions of emotion and chronic-schizophrenia patients. In contrast, the present research examined the ability of patients with acute paranoid and nonparanoid (disorganized) schizophrenia to recognize genuine as well as posed facial expressions of emotion. Evidence of an emotion-recognition deficit in schizophrenia was replicated, but only when posed facial expressions were used. For genuine expressions of emotion, the paranoid-schizophrenia group was more accurate than controls: nonparanoid-schizophrenia patients, and depressed patients. Future research clearly needs to consider the posed versus genuine nature of the emotional stimuli used and the type of schizophrenia patients examined.
