Impaired Perception of Affective Prosody in Schizophrenia

Received October 10, 2003; revised May 27, 2004; accepted July 13, 2004.

The authors aimed to explore schizophrenia patients’ ability to perceive affective prosody. Specifically, certain emotions that may be more troublesome for patients and possible gender differences in prosody perception were assessed. Thirty six schizophrenia patients and 32 age-, education-, and gender-matched healthy comparison subjects assessed on an affective prosody test were examined. Patients were impaired on recognition of affective prosody overall, and their difficulties with prosody perception may be attributed to those emotions with negative valence, specifically anger and sadness. Findings revealed that only male patients were impaired on prosody perception. Deficits in the perception of affective prosody were principally evident in emotions with negative valence and male patients with schizophrenia. Future studies should explore the influence of these deficits on social and interpersonal functioning more directly.
