Reversal learning and resistance to extinction: A supplementary report

Several very recent and highly relevant articles provide substantiation for some hypotheses advanced in a previous review in an analysis of the overtraining reversal data. These same data permit the rejection of an hypothesis advanced by another reviewer to account for the results. It can now be shown fairly conclusively that amount of reward determines the direction of the ORE following position response training and that the variables affecting overtraining reversal data with exteroceptive discriminative stimuli remain unidentified.
