초록
본 연구에서는 정신분열병 환자가 두 명 이상의 대상과의 대화 상황에서 긍정 혹은 부정 정서를 느낄 때 대상에게 시선을 배분하는 특성을 살펴보았다. 정신분열증 환자는 주로 정서를 제공하는 대상에게는 시선을 덜 배분하였고, 주변 대상을 향하는 시선이 증가되어 있었으며, 이러한 경향은 부정적 상황에서 더욱 두드러졌다. 본 연구의 소견에 따라, 그 동안 평가하기 어려웠던 실제적 상황에서 정신분열병 환자들의 사회인지 특성이 평가 가능하며, 향후 보다 진전된 연구와 치료 프로그램 제작 및 활용도 구현 가능할 것으로 예상된다.
Abstract
ObjectivesZZImpairment of social cognition affects the social functioning of patients with schizophrenia. For example, patients with schizophrenia have been shown to display abnormal eye contact during a one-on-one conversation. This study was designed to investigate the behavioral characteristics of patients with schizophrenia while talking with two people. MethodsZZTwenty six patients with schizophrenia and 26 normal controls performed virtual reality conversation tasks, in which they talked with main and assistant avatars under positive or nega-tive emotional conditions. While listening and speaking, the durations of eye gaze with the main and minor avatars were measured from the head orientations of the participants using a positional tracker. ResultsZZCompared with normal controls, the patient group showed a shorter duration of gaze to-wards the main avatar and a longer duration of gaze towards the assistant avatar. This pattern was more apparent in the negative situation. ConclusionZZThe results suggest a defect in social cognition, in which patients with schizophrenia fail to distribute their gaze appropriately during a conversation with more than one other person.
