Stimulus-induced eating when satiated.
Two studies investigated factors that promote the desire for food when people are not energy depleted. In Study 1, 20 male and female subjects, tested under conditions of either hunger or satiety, were exposed to one of two palatable foods (pizza or ice cream) and then given more of that food to eat. Operationally-satiated subjects still ate pizza or ice cream, and the sight of these foods enhanced reported desire for them. The amount of these foods consumed was predicted by the subjects' self-reported desire for the food. In Study 2, 28 male subjects were fed to satiety, then primed with either pizza or ice cream (or not primed at all) and then given both pizza and ice cream to eat. Results showed that a brief taste of a desirable food enhanced its intake relative to the other, equally-preferred food. The data are discussed in the context of the effects of priming as a form of appetite whetting. Also, it is suggested that our operations for eliciting stimulus-induced eating in sated subjects may be useful for future examinations of the psychological properties of craving.
