Replacement Behavior following Deprivation of Food,Water,Running,or Light

Abstract

In 4 separate experiments albino rats were allowed to stabilize in rate on an activity (eating, drinking, light-exposure, or running), after which they were deprived of that activity for a time ranging from 2 to 8 days for different groups. The intent of the methodology was to apply the classical test for “drive”—increased comsummatory behavior following deprivation—to 4 different response measures and to examine in detail the time-course of deficit elimination. Food and water deficits were replaced in an orderly fashion requiring about 3 wk. for completion. Deficits of running activity were not replaced. Compensation for deficits of light was intermediate, showing a little replacement on the first day after deprivation, but no clear evidence of replacement thereafter.
