- This study addressed the effects of blocking spontaneous sniffing during olfactory imagery. A group of subjects (n=40) who scored high in olfactory focus and imagery ability rated the vividness in olfactory and visual imagery content under conditions of blocked sniffing, blocked vision, and a nonblocked control. The imagery stimuli consisted of 90 common words that could represent either an odor or a visual object. Blocked sniffing was expected to impair olfactory imagery vividness, but since visual imagery entails eye movements, which was not affected by the ""blocked vision"" manipulation, visual imagery ratings were effectively used as a placebo control. Confirming our hypotheses, the results showed that preventing sniffing resulted in a selectively poorer olfactory but not visual vividness, whereas blocked vision showed no effect on either the visual or olfactory vividness ratings. These observations confirm that sensorimotor activity is an important aspect for the quality of evoked olfactory images.

- The influences of perceived odor qualities on the retention of olfactory information across the adult lifespan were examined. Young (19–36 years), young-old (60–74 years), and old (75–91 years) adults (n = 202) rated a set of unfamiliar odors across a series of perceptual dimensions (i.e., pleasantness, intensity, and irritability) at encoding. The overall results indicated that memory for unpleasant olfactory information was better than that for pleasant odors across the lifespan. Also, participants showed better retention for odors perceived with high intensity and irritability than for odors rated with low or medium scores. Interestingly, the old adults showed selective beneficial memory effects for odors rated as highly irritable. To the extent that perceptions of high irritability reflect an activation of the trigeminal sensory system, this finding suggests that older adults may use trigeminal components in odor information to compensate for age-related impairments in olfactory memory.

Is it easier to match a name to an odor or vice versa?

- Previous literature and common belief suggest a cognitive asymmetry in the odor–name relationship such that it would be easier to match a name to an odor than the other way around. We tested whether it is more difficult to smell an odor and then choose a proper name among three alternatives than to read an odor name and then choose a matching odor among three alternatives. Although instances of an asymmetry are suggested, in both directions, depending on which odors or odor names are involved, the overall conclusion is that no general unidirectional asymmetry is evident. This was true for odorants of both high and low familiarity and identifiability. Different cognitive factors in a complete model of odor–name matching are identified and discussed.
