초록

이 연구는 정서맥락의 영향이 정서처리의 주의배분 정도에 따라 달라지는지 밝히기 위해 수행되었다. 이를 위해 정서자극과 함께 제시되는 이차 과제의 난이도를 조작하여 정서자극에 배분되는 주의용량을 조절하고, 주의배분 정도에 따라 정서맥락의 영향이 달라지는지 살펴보았다. 연구 결과, 이차 과제의 난이도 수준에 따라 정서맥락에 따른 정확 재인율과 ERP 진폭이 달랐다. 저난이도 조건에서는 정서맥락에 따른 정확 재인율의 차이가 유의미 했지만, 고난이도 조건에서는 정서맥락에 따른 차이가 없었다. 또한 LPC를 반영하는 400-700ms 사이의 ERP 평균 진폭도 이차 과제의 난이도와 정서맥락 간 상호작용효과가 유의미했다. 특히 두정영역에서 저난이도 조건에서는 부정맥락이나 긍정맥락에 비해 중립맥락 내 단어의 ERP 평균 진폭이 높은데 비해 고난이도 조건에서는 정서맥락에 따른 뇌 활성화 패턴 차이가 보이지 않았다. 이 결과는 정서자극에 대한 처리가 주의 배분 정도에 따라 달라짐을 시사한다.

Abstract

This study examined whether attention allocation to the emotional stimuli can be modulated. This study were performed an emotional picture and a neutral word were presented in succession at every trials. And secondary tone judgement task was simultaneously performed during encoding of emotional pictures and the difficulty of the task was manipulated in order to modulate the attention allocation. Recognition judgement results showed poorer memory of neutral words in emotional context than those in neutral context in the easy secondary task condition, but showed no emotional context effect in the difficult secondary task condition. LPC showed the similar pattern: lower amplitude by neutral words in the emotional context than those in the neutral context when the secondary task is easy, but no effect of emotional context when difficult. These results suggest that attention allocation to the emotional stimuli can be modulated.
