Abstract
Rats were given equal experience with alternatives which were either continuously or partially reinforced. A reduction in the stimulus overlap between discriminanda increased the tendency toward a conventional PRE within Ss in terms of differential speeds; but on free-choice trials, all Ss more frequently chose the previously continuous-reinforcement alternative, and this was uniform across conditions.
