Variable reward and choice behavior of rats

Abstract

Reward conditions for a correct response were varied for three groups of rats in a T maze. Groups 2-0 and 4-0 received 50% reward for correct responses with two and four pellets, respectively. Group 4-2 received four pellets for 50% of the correct responses and two pellets for the other 50%. Performance of Group 4-2 was predictable from performance of Groups 4-0 and 2-0.
