A few studies focused on emotion influence on cognitive flexibility and mixed result was found. Hence, this study aims to understand how emotion affects on cognitive flexibility. Three emotional films which divided into neutral, positive, and negative emotion were presented to 48 college-aged participants. Participants requested to finish a task-switching paradigm after watching each film. Four aspects of cognitive flexibility were considered which were switch cost, congruency effect, mixing cost and fadeout effect. The results showed that reaction time (RT) switch cost in negative emotion was smaller than neutral emotion in incongruent condition. In congruency effect, proportion of error (PE) in negative emotion was lower than neutral emotion in incongruent condition. In the fadeout effect perspective, the result showed that the size of RT fadeout effect was greater in negative emotion than in neutral and positive emotion. There was no effect of emotion on RT/PE mixing cost. An implication of this result is that emotion is not always good or bad on cognitive flexibility, it dependents on task demands. Our results supported mood as information theory. In compare with neutral and positive emotion, negative emotion narrow down attention scope and inflexible.
