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.
