Sensory-specific satiation refers to the decrease in pleasantness derived from a food with its consumption, relative to other unconsumed foods. Consumption of a specific food leads to a decrease in liking for the different sensory aspects of that food. In the current study, it was investigated to what extent sensory-specific satiation is truly sensory specific. To this end, 80 female participants ate a preferred snack food until full while wearing (or not wearing) a blindfold and/or a nose clip. Not being able to see the food one is eating should impede satiation for specifically the appearance of the food. Obstructing olfaction should specifically save the hedonic evaluation of food aroma from satiation. It was found that participants ate less of the test snack when they wore a nose clip, especially when they could see the test snack they were instructed to consume until full (F[1,76]=4.95, p<.05,ηpartial2=.06). Moreover, when sight was obstructed during consumption of a test snack, hedonic ratings of appearance of the snack did not seem to decrease as much (F[1,75]=3.49, p<.08,ηpartial2=.04). When sense of smell was impaired, the hedonic ratings for particularly the flavour of the food did not decrease as much (F[1,75]=3.89, p<.05,ηpartial2=.05). It is concluded that, to a degree, sensory-specific satiation is indeed sensory specific.
