Emotional Recognition of Musical-Auditory and Artful-Visual Stimuli in Patients with Chronic Schizophrenia / 신경정신의학

ABSTRACT

OBJECTIVES: OThis study aimed to explore the difference in emotional recognition of musical auditory stimulation and art-related visual stimulation between subjects with and without schizophrenia. METHODS: Twenty songs and 20 paintings that evoke sad or cheerful emotions were presented to 123 patients with schizophrenia and 224 non-schizophrenic people (control group). All subjects were asked to describe the emotions they felt during each auditory stimulation and each visual stimulation. To measure the emotional responses, the Emotional Empathy Scale was used. For members of the patient group, the levels of psychopathology and thought-related disorder were evaluated by using the Positive and Negative Syndrome Scale and the Formal Thought Disorder Rating Scale, respectively. RESULTS: The rate of correct answers to musical auditory stimulation in the schizophrenia patient group was significantly lower than that in the control group. In addition, the rate of correct answers to the art visual stimulation in the patient group was significantly lower than that in the control group. Moreover, the patient group showed lower emotional empathic ability than that shown by the control group. In the patient group, the correct answer rates to the musical and art stimulations were negatively correlated with the Formal Thought Disorder Rating Scale. CONCLUSION: Patients with schizophrenia have difficulty in achieving accurate emotional recognition of auditory and visual stimulations. This difficulty is associated with the lowered empathic ability and altered thinking disorder of patients with schizophrenia.
