초록
본 연구는 정신분열증의 인지기능이 긍정적 정서와 부정적 정서의 인식에 어떤 영향을 미치는지 확인하고자 하였다. 이를 위해서 본 연구에서는 6가지 기본정서를 표현하고 있는 22개의 얼굴표정사진을 컴퓨터 화면을 통해 정상인과 편집형 정신분열증 환자, 그리고 비편집형 정신분열증환자에게 제시하였다. 그리고 각 사진의 인물이 경험하고 있는 정서에 가장 적합한 기본정서목록을 보기 중에서 선택하게 하는 얼굴정서명명과제와 각 사진의 얼굴표정에 대한 쾌/불쾌의 방향과 강도(intensity)를 평가하게 하는 쾌/불쾌 평정과제를 수행하게 하였다. 그 결과 긍정적 정서에 대한 쾌/불쾌 평정은 집단간의 차이가 없었으나 정서명명에 있어서는 비편집형 정신분열증의 수행이 유의하게 저조하였다. 부정적 정서에 있어서는 정상인, 편집형 정신분열증 환자, 그리고 비편집형 정신분열증 환자의 순으로 정서명명과 쾌/불쾌 평정이 정확하였다. 이러한 결과는 정신분열증의 하위 유형에 따른 인지기능이 정서정보의 처리에 영향을 미치고 있음을 시사한다. 또한 정신분열증의 재활과정에 정서인식에 대한 훈련이 필요하며, 그 훈련이 정신분열증의 하위유형에 따라 달라야 함을 시사한다.
Abstract
The purpose of this study was to investigate the effect of cognitive function of schizophrenia on emotional recognition. the subject were presented with 22 photographed face with 6 basic emotional expressions in computer monitor. And the subject were asked to identify which of the emotions best represents the affect expressed by the face(emotion identification task), and to rate the direction and intensity of facial emotion of photograph(pleasure/unpleasure rating task). The results showed that the differences of pleasure/unpleasure rating to positive emotions between subjects was not significant and normal/schizophrenia paranoid was higher than schizophrenia nonparanoid in scores on face emotion identification task. In negative emotion, there was significant difference between normal, schizophrenia paranoid and schizophrenia nonparanoid on the pleasure/unpleasure rating. And, normal, schizophrenia paranoid, schizophrenia nonparanoid obtained the higher scores on the emotion identification task in order. These results suggest that the difference of cognitive function among three groups can be expanded into the processing of emotional information and the subtype of schizophrenia can be assigned by the level of processing of emotional information. In addition, these results implicates that the application of emotional recognition program need for psychiatric rehabilitation in schizophrenia treatment and the training of emotional recognition should differ in schizophrenia subtype.
