Abstract
The self-choice effect is the superior memory performance observed when participants are allowed to choose the items at the study phase. Kawasaki, Itsukushima and Yama (2011, ICOM5) revealed that as for list words self-choice effect was observed, but as for critical lures no self-choice effect was observed with DRM paradigm. In this experiment, we investigated the effect of duration and self-choice effect on true memory and false memory. Participants studied DRM lists in forced-choice and self-choice conditions and took two recall tests immediately and 1-week later. As a main result, recall of list words decreased, but that of critical lures increased with the duration. Hence fuzzy trace theory was supported.
