Abstract

We examined the effects of cognition on the hedonics of three typical offensive odor pollutants. One hundred fifty-four healthy women and men were exposed to one of three odors (ethyl acetate, hydrogen sulfide, or ammonia), which are regulated as odor pollutants in Japan, after being told that the odorant was healthful, neutral, or harmful. Participants continuously rated the odor intensity for 10min using a slide lever. A measurement system for odor adaptation controlled the concentration and duration of the presented odor, and recorded the intensity of the responses every 50ms. After the presentation of the odorant, the participants ranked the hedonics (pleasantness-unpleasantness) of the odor using a visual analog scale from -100 (very unpleasant) to +100 (very pleasant).<BR>The results revealed the effects of cognition on the hedonics of offensive odorants. These effects, however, were different for the three odor pollutants ; the largest effects were observed with ethyl acetate, whereas the smallest effects were observed with ammonia. These results should help to address problems associated with individual differences in the regulation of odor pollution.
