Retrieving positive memories to regulate negative mood: consequences for mood-congruent memory.

Several researchers have suggested that mood-incongruency effects are due to a mood-regulatory process in which people retrieve positive memories to repair negative moods. The present studies tested this idea by manipulating mood-repair strategies and examining their impact on positive and negative memory retrieval. Mood-congruent retrieval occurred when participants stayed focused on events associated with their negative mood; mood-incongruent retrieval occurred when participants engaged in positive reappraisal (when they reinterpreted events as having positive outcomes). The effects of these strategies on memory retrieval also interacted with personality traits related to negative mood regulation. Individuals high in such traits showed stronger mood-incongruent memory than did individuals low in negative mood-regulation traits. Discussion focuses on integrating mood-regulatory variables and personality variables into existing mood-congruency theories (e.g., associative network models).
