The purpose of this study was to examine how emotional experience and emotional expressivity differ among three groups: a group with high-negative symptoms including anhedonia (high-negative symptoms group), a group with low-negative symptoms including anhedonia (low-negative symptoms group) among patients with schizophrenia, and a normal group. With the criteria of PANSS and anhedonia scales, 15 persons for high-negative symptoms and 15 for low-negative symptoms were chosen. And to examine the mental health status of the normal group, the anhedonia scale was conducted and 15 persons were chosen to the exclusion of those with SCL-90-R and anhedonia. For emotional experience, this study utilized the International Affective Picture System (IAPS) containing various ranges of contents. This research had the participants see positive and negative emotional photos for 6-15 seconds from a notebook. After that, they were made to rate their emotional state they experienced from 1 to 9 according to the appraisal method of SAM (Self-Assessment Manikin). For emotional expressivity, this paper used the Emotional Expressivity Scale (EES), a self-reporting questionnaire. According to the result of this research, schizophrenia patients rated positive emotion less positively and negative emotion more negatively than the normal group, and they gained lower scores in emotional expressivity. And among the schizophrenia patients, the high-negative symptoms group rated positive emotion less positively and negative emotion more negatively than the low-negative symptoms group, and they gained lower scores in emotional expressivity. The implications and limitations were discussed along with some suggestion for the future studies.
