초록

작업기억 부담이 부적 얼굴정서 처리에 미치는 영향을 밝히기 위해, N-back 과제 수행 도중 제시된 부적 얼굴표정에 의해 유발된 ERP성분들을 조사하였다. 한 개씩 순차적으로 제시되는 시각적 사물그림들에 대한 기억을 유지하고 갱신하도록 요구하면서(N-back 과제) 이 사물그림들이 제시되는 사이에 공포표정 또는 중립표정의 얼굴자극을 하나씩 제시하였는데, 작업기억 부담을 0-back 조건(저부담)과 2-back 조건(고부담)으로 조작하였다. N-back과제 수행반응을 분석한 결과, 고부담조건에 비해 저부담조건에서 더 빠르고 정확한 반응이 관찰되었다. 얼굴자극에 의해 유발된 ERP 평균진폭을 분석한 결과, 후두영역에서 측정한 P1 진폭에서는 정서가효과는 유의미하지 않았고 작업기억 부담효과만 유의미하였다(고부담 > 저부담). 후측 후두-측두 영역에서 측정한 N170 진폭에서 얼굴 정서가효과는 전반적으로는 유의미하였지만(부정 > 중립) 세부적으로는 작업기억부담과 반구에 따라 다르게 나타났는데, 정서가효과가 좌반구에서는 저부담조건의 경우에만, 우반구에서는 두 부담조건 모두에서 관찰되었다. 결국, 얼굴표정의 부적 정서가가 N170에 미치는 영향이 좌반구에서는 작업기억 부담에 의해 조절되었지만 우반구에서는 그렇지 않았다. 이러한 결과는, 부적 얼굴 표정의 초기 정서처리가 작업기억의 유지 및 조작 부담이 큰 경우 좌반구에서는 약화되거나 일어나지 않을 수 있는 반면, 우반구에서는 작업기억 부담의 크기에 관계없이 일어남을 보여주는 것으로써, 부적 얼굴정서 처리의 우반구 편재를 시사한다.
