Abstract

Previous research has suggested conditions for the learning of the non-rewarded instead of the rewarded of two alternatives. Two experiments were performed with a reconvergent maze, in which food reward depended upon passing through only one of the two pathways. Rats given a block of non-rewarded then a block of rewarded trials chose predominantly the rewarded pathway during free-choice extinction testing, but those subjected to simple alternation sequences of rewarded and non-rewarded trials chose primarily the non-rewarded pathway. Faster running on non-rewarded trials preceded choice of the non-rewarded pathway by alternation subjects, and the evidence suggests that increased training led to greater preference for the non-rewarded alternative.
