Some effects of deprivation on eating and drinking behavior.

Abstract

Study of the responses of rats maintained on 23-hr. food or water deprivation schedules showed that a number of trials were necessary before the animals ate or drank readily during the first 7 minutes of the reward period. Latencies decreased during the testing period. "It is concluded that the arousal and maintenance of both hunger and thirst are related to past experiences of need followed by appropriate eating or drinking.".
