Cognitive theories suggest that information processing biases play a central role in the development and maintenance of emotional disorders. The purpose of this study was to investigate the presence of explicit and implicit memory biases for emotional information in subclinically depressed (N=20) and normal controls (N=20) individuals. Participants were students at the University of Arak and were selected according to their scores on the Beck Depression Inventory (BDI, 1978) and General Health Questionnaire (Goldberg and Hiller, 1979). Four types of word (depression related, social threat related, positive and neutral words) were used in the explicit and implicit memory tasks. Explicit memory was assessed with a free recall and implicit memory with a word- stem completion task. Results of Repeated Measure Analysis of Variance showed that the depressed group showed a mood congruent memory bias at free recall. The results of this study failed to show the existence of a mood congruent memory bias for implicit memory in depressed individuals. The theoretical implications of these findings were discussed.
