Mood effect in the daily recall of past event

Two tests examined whether mood congruent memory bias is found in the daily recall of personal past event. Subjects described their memories about past events unexpectedly recalled, and then completed the questionnaire to assess affective value of their past events and to assess their mood states both at the time recalled their past events and at the time tested. When affective value of past event was evaluated by desirability, mood effect was not found (Test 1). While, when past event was evaluated by the same measure as mood rating, subjects who were in the positive mood recalled more positively past events than those in the negative mood (Test 2). The difference between the results of two tests was discussed with respect to the variety of affective value rating for memory and mood reparative effect. In addition, these results suggest that mood has an influence on unexpected memory process as daily recall.
