- Hedonic responses to odors are thought to derive from experience with those odors. Although increases in liking as a result of simple exposure to sensory stimuli is well known, there has been little study of how such processes might be cognitively mediated. The finding that ignoring a stimulus during a single exposure can lead to its devaluation (Raymond et al., Psychol Sci 14( 6), 537-542, 2003) raises the possibility that attention may similarly influence the hedonic responses following repeated exposures. In the present study, different odors were designated as targets or nontargets in an identification task, but otherwise, they were equally exposed. Only liking for targets increased following exposure, but it was unclear if this reflected enhancement of liking for targets or devaluation of nontargets. This was tested in a second study in which a replication of the Exp 1 conditions was compared with conditions in which odors were exposed without an accompanying task. The fact that these latter odors showed no increase in liking following exposure suggests that active attention may be an important determinant of exposure effects. The generality of such conclusions may be limited, however, due to the fact that odors are long duration stimuli for which feature analysis is difficult.
