Abstract: Employing L. L. Jacoby ' s process dissociation procedure (Jacoby, 1991 ), An experiment was designed to investigate whether mood-congruent memory bias is a function of implicit or explicit memory. The result showed: mood-congruent memory bias was found in explicit memory but not in implicit memory. The findings demonstrated the involvement of elaborative mechanisms in mood-congruent memory. In addition, explicit memory deficit was found in depressed participants, but no implicit memory deficit was found in them. Some directions for future research were discussed at the end of the paper.

Key words: mood-congruent memory, process dissociation procedure, depression
