This study investigated the influence of odor cueing on the retrieval process for autobiographical memories. In Experiment 1, forty two participants were asked to retrieve autobiographical memories in response to a label cue only, or a label cue with a congruent odor cue, or label cue with an incongruent odor cue. The results showed that in the label cue only condition and the incongruent odor cue condition, the latency with a concurrent task was slower than with no concurrent task. However, this was not observed in the congruent odor cue condition. In order to verify the results of Experiment 1, in Experiment 2, twenty participants were investigated with regard to autobiographical memories cued by odors having a high or low rate of identification. The results showed that memories cued by odors with a high rate of identification were retrieved faster. These results suggest that dual processing by odor and label promotes retrieval processes for autobiographical memories.
