The effects of cue modality on the quality of personal memories retrieved.

We investigated the effect of cue modality on the specificity, speed, vividness, and age of autobiographical memory retrieval. Cues were presented as either an odour, a visual image, or a word label. Odour-cued memories were older, more likely to be categoric, and were slower to be retrieved. Few gender differences were found although females reported more vivid memories than males. We suggest that cue modality directly affects retrieval processes; odour cues are more likely to initiate a perceptual search strategy, in contrast to memories cued by visual images and words, which are usually conceptually/verbally mediated.
