Abstract

Several studies have investigated the ability of schizophrenics to perceive facial and vocal emotion in others. Although most suggest that schizophrenics have an emotion perception deficit, there is little agreement as to its specific nature. Much of the confusion may be attributed to the failure of investigators to use the differential deficit design and standardized measures of emotion perception. The present study reexamined the question of an emotion recognition deficit in a sample of 29 unmedicated schizophrenics and 23 normal controls, using facial and vocal emotion identification and discrimination tests that have been standardized and cross-validated plus two neuropsychological control tests. Results suggested that differences between schizophrenics and normals on such tasks reflect a generalized performance deficit, rather than a specific emotion recognition deficit.
