[Study of the emotional range of schizophrenic patients in a model of emotion recognition through nonverbal expression]

Emotional characteristics of schizophrenic patients have been studied using an experimental model of emotion recognition. It has been shown that with further emotional depression and depletion schizophrenics show a deterioration of the accuracy of recognizing nonverbally expressed (by gestures, postures, or mimics) emotions and an increased tendency for non-emotional interpretations. The study has revealed a complex nonuniform nature of these changes, their dependence on the degree of the situation recognizability, on the channel of emotional information transmission, as well as on the sign, modality, and intensity of emotion expression by another man. The results obtained are interpreted as a sign of empathy diminution, of an increase in emotional "dullness" in intercourse, and of "glass and wood" symptom in patients with schizophrenia.
