Subjective ratings of the pleasantness (0, not pleasant; 100, very pleasant) of the food outcomes before training as well as before and after the selective outcome devaluation. Subjects initially preferred the rewards (chocolate milk and orange juice) over the common and neutral liquids (peppermint tea and water, respectively). The selective satiation decreased the pleasantness rating for the eaten (devalued) food significantly compared with the food not eaten (valued). Data represent means ± SEM.
