Abstract

Rats were trained to run down a 100-ft.-long runway for food; shock was then introduced at the goal and increased on subsequent trials until S failed to reach the goal. Under 24-hr. deprivation, test trials were run with S started near the goal and then far from the goal; the 1st movement of most Ss was toward the goal under both conditions. When hunger was reduced to 4 hr. and then increased by 24 hr. on each successive trial, all Ss approached part way and then stopped on most trials, generally approaching closer to the goal on the trials conducted under conditions of greater hunger.
