title: Odors as cues for the recall of words unrelated to odor.
abstract: The effectiveness of an ambient odor as a retrieval cue for words unrelated to odor was investigated. After incidental learning of 40 adjectives, 40 participants were tested for recall during three unannounced recall phases (15 min., 48 hr., and 5 days). Participants in two control conditions learned with no odor present and either had no odor present during any recall phase or only during recall after 5 days. Participants in two conditions learned with an odor present and either had the odor present during recall only after 5 days or during recall both after 15 min. and after 5 days. Analyses indicated that, while participants in the control conditions recalled significantly less during each succeeding recall phase, recall by participants in the two experimental conditions did not decrease significantly. Recall by participants in the two experimental conditions was significantly higher during recall after 5 days (when the odor was reintroduced) than either control group. The addition of a salient cue during learning and retrieval facilitated recall more than the presence of constant environmental cues.
