Abstract

A theoretical model is proposed for the interaction of the effect of number of training trials and magnitude of reward on speed of reversal learning. The model was tested by an experiment involving 2 levels of reward magnitude and 4 degrees of training. An overlearning reversal effect was obtained under large reward but not with small reward. The data from the 8 groups of rats were well within chance limits of the quantitative predictions from the model.
