| Outline of Final Research Achievements |
The act of remembering can cause forgetting. Successful retrieval not only facilitates later recall of the retrieved items, but also impairs later recall of the related or competing items in memory. This memory phenomenon has been demonstrated with the retrieval-practice paradigm introduced by Anderson et al. (1994). In this study, we demonstrated the “retrieval-induced forgetting” phenomenon in a spontaneous object recognition test in rats. Additionally, administration of drugs which have detrimental effects on memory retrieval diminished the phenomenon.
