Abstract
Previous studies have reported that positive autobiographical memories are involuntarily retrieved on a daily basis and often accompany mood changes. Previous studies have used subjective report methods to measure the impact of involuntary retrieval on mood. However, subjective report methods are known to be easily distorted by social desirability and demand characteristics. To avoid this problem, we applied the measurement of implicit mood and examined the impact of involuntary positive memory on mood. Sixty-four participants participated in the experiment and 48 participants were included in the analyses. Participants carried out an easy task in which the retrieval cue was presented, to induce an involuntary positive memory. Participants were also asked to rate the mood of nonsense words in order to measure implicit mood before and after the task. The results demonstrated that the involuntary positive memory retrieval increased positive mood in participants who exhibited lower positive implicit mood before the involuntary memory retrieval. We experimentally demonstrated that involuntarily retrieved positive memories can improve implicit mood.
