The purpose of this study was to examine the effect of the valence and arousal on the incidental learning tasks. Participants performed either one of the perceptual identification task and lexical decision task which are different in the level of processing. Later, a series of words were displayed and participants were asked to recognize whether or not each test word was shown when they performed a task. The results showed that, regardless of the tasks performed, words with negative valence were recognized better than those with neutral valence. Also, words with higher arousal level were recognized worse than those with lower arousal level. The results indicate the differential effects of the valence and arousal on cognitive processes. The results further suggests that the inconsistent findings across previous studies might be due to the failure of dissociating the influence of stimulus’ emotional valence and arousal level.
