Two experiments examined the acquisition and loss of 'craving' or liking for a food (unsalted peanuts). In Experiment 1, subjects were allocated to three conditions. In each of these, they ingested a few peanuts on three separate occasions and were then asked to indicate the strength of their cravings for that food. The conditions differed in terms of the intervals of time (1, 3, or 9 min) which occurred between the eating bouts. The shortest of these intervals yielded a greater proportion of subjects who expressed strong craving than either of the other two intervals. In Experiment 2, subjects were asked to eat the nuts with the I-min interval between each of the three eating bouts and were then allocated to three conditions. These differed in the intervals of time (1, 3, or 9 min) which occurred between the final eating bout and the time at which they were asked to indicate the level of their craving. The longest of these intervals produced a greater proportion of subjects who reported weak cravings than the other two intervals. Short intervals of time between mouthfuls of a food were therefore more likely to establish and maintain 'cravings' for that food than longer ones. The results were discussed in terms of incentive and opponent-process accounts of motivational phenomena. [ABSTRACT FROM AUTHOR] |
