Involuntary memories are memories of past events that come to mind with no preceding attempt directed at their retrieval. Previous studies have shown that retrieval of involuntary positive memories during negative mood alleviates the mood. However, it remains unclear whether the involuntary positive memories retrieved during negative mood are less in number than the involuntary negative memories because the influence of emotional valence of the retrieval cue is confounded. Therefore, this study examined the influence of negative mood on the emotional valence of the involuntary memory using the neutral retrieval cue. Twenty-three participants were randomly assigned to positive or negative memory condition. They encoded associated memory of images and sounds and performed the involuntary memory retrieval task. As a result, no significant difference was found between the number of involuntary positive and negative memories. Further, mood repair effect was found only in participants with positive memory. These results suggest that mood before involuntary memory retrieval influence the retrieval cue, not the emotional valence of memory.
