Abstract

Several studies have indicated that there is a general improvement in mental work performance under odor exposure. However, in these studies odor stimuli were prepared experimentally without considering individual differences for odor preference and impression. In this study, participants chose an odor according to their preference (Exp. 1) or feeling of arousal to perform tasks (Exp. 2) and whether the odor improve performance was examined. The tasks with low-difficulty and high-difficulty were done. As results, subjective refreshing odors improved task performance, whereas favorite odors only maintained reduction of mood for the high-difficulty task. These results suggest that a subjective refreshing odor maintained adequate vigilance to improve task performance of low or high difficulty.
