Abstract
A Presentation rate (4 s or 8 s per word) x Context (same or different context) between-participants design was used. Sixty-four undergraduate participants individually participated in a 20-min experiment. The participants incidentally learned 20 words in the presence of an odor randomly selected from two pair of odors (celery - apple, grapefruit - coffee), which had been selected from 17 odors by a preliminary study. Following a 5-min filled retention interval in the absence of such odor, participants unexpectedly required to free recall the encoded words orally for 60 s in the presence of either the same odor as at encoding or a different odor. Significant context-dependent free recall was found in 4-s condition but not in 8-s condition. The results were discussed in terms of adaptation and outshine hypothesis.
