The purpose of this study was to investigate the mood-congruence memory(MCM) bias of implicit memory in depressive population. Study is nonclinical and clinical group. A total of 567 undergraduate university students for nonclinical group screened with the self-report format of the Beck Depression Inventory(BDI). According to BDI score, participants were randomly assigned to two groups with high(n=27) versus low levels(n=27) of dysphoria. The sample for clinical group consisted of 20 participants who met DSM-IV diagnostic criteria for depression(n=10) versus normal controls(n=10). MCM bias in depression was investigated using a picture discrimination task, pictures were selected according to three levels of affective valence(negative, neutral and positive). Results showed no MCM bias in a picture discrimination task, but priming effect. These showed that priming effects of implicit memory reflect pre-learning experience. Moreover, results suggest that depressive level may have influence on mood-congruent effect, although significant difference was not in between nonclinical and clinical groups. Finally, the clinical implications and limitations of present study were discussed.
