Emotion processing of people with psychopathic tendency

본 연구는 두 가지 웹-기반 얼굴정서판단과제와 변화맹시-얼굴정서과제를 이용하여 정신병질 성향군의 정서처리 특성을 알아보고자 하였다. Levenson 자기보고식 정신병질 질문지(LSRP)와 Welsh 불안 척도(WAS)를 이용하여 대학생들을 대상으로 일차 정신병질 성향군과 통제군을 선발하였다. 연구 1에서, 정신병질 성향군이 통제군에 비해 특정 정서를 처리하는데 결함을 보이는지 살펴보기 위해 얼굴정서판단과제를 실시하였다. 그 결과, 정신병질 성향군이 통제군에 비해 행복과 놀람 정서를 판단하는데 유의하게 낮은 정반응을 보였다. 반면에 공포와 슬픔 정서에서는 정반응에서 유의한 차이를 나타내지 않았다. 연구 2에서, 특정 정서를 지각하여 화면의 변화를 탐지하는데 있어 주의 결함이 보이는지 알아보기 위하여 변화맹시-얼굴정서과제를 고안하여 실시하였다. 분석 결과, 정신병질 성향군은 통제군에 비해 행복, 공포, 분노, 혐오, 슬픔, 놀람 정서의 변화를 주의하여 지각하는데 유의하게 느린 반응시간을 보였다. 결과를 요약하면, 1) 정신병질 성향군은 통제군에 비해 행복과 놀람 정서를 인식하여 처리하는데 어려움이 있었다. 2) 또한 정신병질 성향군은 공포, 슬픔 정서뿐 만 아니라 혐오, 분노, 놀람 정서와 행복 정서의 변화에 주의를 기울여 변화를 탐지하는 데 결함을 보였다. 마지막으로, 본 연구의 결과들이 향후 정서 처리와 관련된 정신병질 평가 도구를 개발하는 데 도움이 될 수 있는 시사점과 본 연구의 제한점을 논의하였다.

Abstract

This study examined the characteristics of emotion processing in people with psychopathic tendency using a web-based facial emotion decision task and a change-blindness facial emotion task. A psychopathic tendency and control group were selected out from university students using a Levenson's Self-Report Psychopathy and a Welsh Anxiety Scale. As a result of study 1 which employed a web-based facial emotion decision task, response accuracies of psychopathic tendencies to happiness and surprise was significantly lower than that of control group, suggesting that psychopathic tendency shows some emotion processing deficits. The results for emotions such as fear and sadness, however, were not statistically significant. The study 2, using a change-blindness facial emotion task, examined attention deficits of psychopathic tendencies in emotion processing. As a result, response times in psychopathic tendencies were significantly slower than those of control group in all six measures of emotion (happiness, fear, anger, disgust, sadness, surprise). In summary, 1) the study 1 showed that people with psychopathic tendency have difficulty in processing emotions such as happiness and surprise. 2) the study 2 showed that they also has attention deficits in noticing changes in all six emotional faces. Finally, it was suggested that our results may shed lights on the development of evaluation tools for discriminating psychopaths from normal, and limitations of the current study were discussed.
