The verbal overshadowing effect is the phenomenon in which describing a previously seen face impairs its recognition. The primary purpose of this study was to investigate the effects of negative emotion on verbal overshadowing. In order to induce negative emotions, half the participants were presented unpleasant pictures selected from the International Affective Pictures System at the beginning of the experiment. As a result, we found that verbal overshadowing occurred in the neutral emotion condition, but not in the negative emotion condition. The implications of these findings for research and practice are discussed.
