Abstract

Three dynamic face-processing tasks based on the Bruce & Young (1986) functional model of face processing were presented to 10 schizophrenic and 10 depressed inpatients and to 10 non-patient subjects. Familiar face recognition, facial expression recognition and unfamiliar face matching were examined. Schizophrenic patients' performance was significantly poorer than that of depressed patients and non-patient controls. Significantly lower scores were obtained on the facial expression recognition task than on the familiar face recognition task. There was a differential pattern of group performance on each of the three tasks: schizophrenic and depressed patients were as accurate as non-patient controls on the familiar face recognition task, but significantly less accurate than non-patient controls on the unfamiliar face-matching task. Schizophrenic patients were significantly less accurate than depressed patients and non-patient controls on the facial expression recognition task. The results are contrasted with an analogous static face-processing study.
