Document Summary
Behavioral analyses of responses to this task focused purely on the reinforcement (being told. Awareness, to the degree that it exists, was assumed not to affect sorting. Moreover, average success in concept identification across participants appeared to increase gradually, much like the learning of an athletic skill. First, these investigators analyzed each participant"s responses separately and determined the pattern of correct and incorrect responses prior to the last error. If learning was gradual, as predicted by most reinforcement theories, the probability of a correct sort, within a single participant"s learning trials, should increase gradually from . 50 (the chance probability of being correct ). The gradual increase found earlier was an artifact of averaging across participants who had identified the correct concept at different points of time in the experiment. Moreover, patterns of sorting after each error were indistinguishable irrespective of the point in the experiment at which the error occurred.
