The effect of the task-unrelated valence and arousal on the N-back task performance

본 연구의 목적은 N-back 과제수행에 과제 무관련 사진자극의 정서가와 각성가가 미치는 영향을 살펴보는 것이다. 이를 위해 본 연구에서는 2-back 과제의 자극 사이에 제시된 사진의 각성가 수치는 동일하게 통제하고 정서가를 긍정, 중립, 부정으로 조작한 실험과 정서가는 동일하게 통제하고 각성가를 저각성, 중각성, 고각성으로 조작한 실험을 실시하였다. 그 결과 각성가 조건에 따른 차이는 관찰되지 않았으나 정서가 조건에 따른 차이가 관찰되어 부정정서의 경우 긍정정서 및 중립정서에 비해 과제수행이 부정확했다. 이러한 결과는 각성가의 영향을 배제하였을 때도 부정정서가 N-back 과제수행을 간섭했으며 각성가보다는 정서가의 차이가 이러한 간섭의 원인임을 시사한다.

Abstract

The purpose of this study was to examine the effect of the task-unrelated valence and arousal on N-back task performance. To do so, in the first experiment, participants performed 2-back tasks where valence levels of the pictures presented before the target were manipulated while arousal levels were controlled. In the second experiment, arousal levels of the pictures were manipulated while valence levels were controlled. As results, accuracies of the N-back task were worse when pictures with negative valence were presented. Arousal had no effect on N-back task performance. The results indicate that negative valence affects cognitive processing even when the arousal level were controlled.
