본 연구는 변화맹시-얼굴정서과제, 어휘판단과제, 변화맹시-정서단어과제를 이용하여 자살사고경향군의 주의력 및 정서처리 특성을 확인해 보고자 하였다. 참가자들은 Beck의 우울증척도(K-BDI)와 자살사고척도(SSI-Beck)를 실시하여 자살사고경향군, 우울경향군, 대조군으로 분류되었으며 각 집단간 30명씩 실험에 참가하였다. 연구 1은 비언어적 자극인 얼굴표정자극(공포, 분노, 혐오, 행복, 슬픔, 놀람)을 이용한 변화맹시-얼굴정서과제를 실시하였다. 그 결과 자살사고경향군이 대조군에 비해 낮은 정반응률을 보였다. 연구 2는 언어적 자극인 정서단어(자살, 중성, 긍정, 부정)를 이용한 어휘판단과제 및 변화맹시-정서단어과제를 실시하였다. 그 결과 어휘판단과제 및 변화맹시-정서단어과제에서 자살사고경향군이 대조군에 비해 반응시간이 지체되어 있고, 지속적이고 일관적으로 반응하지 못하였으며, 낮은 정반응률의 수행 특성을 보였다. 특히 정서-일치(mood-congruent)된 단어에서 유의미한 차이가 두드러졌다. 변화맹시-정서단어과제에서 얻어진 지표들이 자살사고경향군과 통제군을 어느 정도 정확하게 분류해주는지를 확인하기 위해 판별분석을 실시한 결과, 변화맹시-정서단어과제에서 종속지표에 대한 판별함수가 유의미한 것으로 나타났으며 세부적인 판별정확도는 70.0%로 나타났다. 이러한 연구결과를 토대로 자살사고경향군의 상담실제에 대한 시사점과 후속연구에 대한 제언을 논하였다.
This study was aimed to explore the attentiveness and emotion processing characteristics of suicide ideation group. To test these hypotheses, ‘Change blindness’-facial emotion subject, the lexical decision subject and ‘Change blindness’-emotion words subject were implemented. Subjects were classified into suicide ideation, depression, and control groups, based on the scores of BDI and SSI. Each group had 30 subjects. Study-1 employed ‘Change blindness’-facial emotion subject using the facial stimulation. As a result, the reaction rate of suicide group was lower than that of the control group. Study-2 used the lexical decision subject using mood-congruent words and ‘Change blindness’-emotion words. As a result, the reaction time of SI group was slower than that of control group in the lexical decision subject and ‘Change blindness’-emotion words subject. Subjects in SI group couldn't react continuously and consistently and showed the lower proficiency. In particular, the meaningful difference was prominent at the mood- congruent words.
