Stimulus Classes Formation in Concurrent Discriminations in Rats as a Function of Overtraining

摘要: The present two experiments conducted a limited parametric study of the overtraining variable using whole-partial reversal procedure in rats. Rats received concurrent two-choice discriminations (Experiment 1), go-no go successive 2), and then training under given condition whole or partial either immediately after criterion training, following 2, 10, 20 days Experiments 1 2. In Experiment 1, overtraining, reversal, which both discrimination tasks were reversed, produced more rapid than condition, one was reversed whereas other maintained as original learning. Conversely, 2 rats faster did those condition. essentially replicated results 1. show that stimulus function transfer substitutability, respectively, are most clearly evident overtraining. These indicate additional prereversal (i.e., overtraining) is an obvious operational precondition for classes formation simple
