Abstract
특성불안이 높은 자들은 분노 표현을 억제하려하기 때문에 주관적인 행동평가로는 특성불안자의 분노 경험을 측정하는데 한계가 있다. 보다 객관적으로 특성불안자의 분노 경험을 측정하기 위하여 본 연구에서는 분노에 의해 유발된 자율신경계 반응이 특성불안 수준에 따라 차이가 있는지를 확인하고자 한다. 실험참가자들을 불안집단과 통제집단으로 구분하였으며, 분노자극을 제시하기 전과 후에 심전도(ECG), 호흡(RESP), 피부전기활동(EDA), 그리고 피부온도(SKT)를 측정하였다. ECG에서 심박률(HR), NN 간격의 표준편차(SDNN), 심박주기 제곱의 평균제곱근(RMSSD), 심박변이도의 저주파성분(LF), 심박변이도의 고주파성분(HF), 저주파성분과 고주파성분의 비율(LF/HF ratio), RESP에서 호흡주기(RR)를, EDA에서 피부전도수준(SCL)을, SKT에서 최대피부온도(maxSKT)를 산출하였다. 두 집단 간 분노자극에서 유발된 분노정서 강도의 차이를 검증한 결과, 집단 간 차이는 유의하였다. 자율신경계 반응 차이를 확인한 결과, 불안집단에서 유의미한 SDNN와 LF의 증가, HF, LF/HF ratio, 그리고 RR의 감소가 나타났다. 본 연구 결과는 특성불안이 높은 이들의 분노 경험을 측정하는데 자율신경계 반응이 객관적인 지표로 활용이 가능함을 시사한다.
