Abstract
Twenty-four rats were run in a successive T maze discrimination, with unequal frequency of stimulus presentation, and mixed random reinforcement. The contingencies of reinforcement were such that consistent position-habit responding would yield 65% random reinforcement, whereas errorless discriminative responding would yield 90% random reinforcement. Learning proceeded in two distinct phases that differed in response content: a position-habit phase, followed by a discriminative phase.
