Abstract
Rats of the Maudsley Reactive and Nonreactive strains were used in two light reinforcement experiments in a Skinner Box with two levers. Different response contingencies were compared in order to test the relative validity of the “stimulus change” and “preference” theories. The results did not support the preference theory, but are consistent with the stimulus change theory.
