Further Studies of Overlearning and Position Reversal Learning

Abstract

The effects of extensive overtraining on position reversal were studied in 2 experiments in which the stimulus complex associated with the choice response was manipulated. In Exp. I a visual cue (brightness) was correlated with the position response. In Exp. II the stimulus consequences of an incorrect response were made highly discriminable by associating an abrupt illumination change with an incorrect choice. Despite these modifications the overlearning reversal effect failed to occur in both experiments, verifying a number of previous reports.
