The role of implicit and explicit memory in hypermnesia was investigated using a priming procedure based on the alternative retrieval pathways (ARP) hypothesis (Kazén & Solís-Macías, 1999). Sixty words were studied in the format-translation condition (pictures were drawn for the words) or no format-translation condition (mirror characters of the words were written). Then, word-stem priming tests were conducted three times immediately and three times one week later. Based upon Bowers and Schacter (1990), the participants were classified into an intention or no-intention group according to the retrieval intention of used in the study episode. The results showed that hypermnesia occurred in the intention group, but not in the no-intention group. The ARP hypothesis could be useful to predict the quality of reminiscence, but not for the occurrence of hypermnesia. Hypermnesia occurred in explicit memory but not in implicit memory in this study.
