본 연구에서는 그림배열과제와 감정귀인과제를 사용하여 정신분열병 환자들에서 마음이론 능력 및 공감 능력에 장애가 있으며, 둘 사이의 연관성이 있음을 확인하였다. 또한 마음이론 및 공감의 손상이 신경인지기능과 연관성이 없음을 확인하였다
Abstract
Purpose：Human are intensely social creatures. One crucial capacity for social interaction is to understand the mental and emotional state of others. While theory of mind refers to our ability to understand mental states such as intentions and beliefs, empathy means the capacity to share the feelings of others. The purpose of this study was to investigate whether there are deficits of theory of mind as well as empathy in schizophrenic patients, and whether mentalizing and empathizing ability are correlated within schizophrenia. In addition, it was aimed to examine whether impairments in theory of mind and empathy are related to working memory. Methods：Twenty-four stable schizophrenic patients and thirty-one healthy subjects participated in this study. Psychiatric patients were recruited from the Department of Psychiatry of Bugok National Hospital. Consensus diagnoses, according to DSM-IV criteria, were obtained by two psychiatrists. Normal controls were chosen based on age, sex, education and IQ similarities with schizophrenic patients. All participants were administrated to the Picture Sequencing Task(PST), as measure of theory of mind, and the Emotion Attribution Task(EAT), as assessment of empathy. They also underwent computerized versions of the Wisconsin Card Sorting Test(WCST). Results：The schizophrenic group performed poorly on both the PST and the EAT relative to controls. There was a significant association between the PST and the EAT in the schizophrenic group. We also couldn’¾t find any relations between mind reading ability and working memory within schizophrenia. Conclusions：These data suggest that schizophrenia have the impairments of theory of mind and empathy, that mentalizing and empathizing ability are correlated, and that impaired working memory does not account for the deficits of theory of mind and empathy in schizophrenia.
