SOME EFFECTS OF DISCRIMINATIVE TRAINING WITH EQUATED FREQUENCY OF REINFORCEMENT

Pigeons were exposed to a multiple schedule which provided equally frequent reinforcement in the presence of two stimuli but which produced markedly different rates of key‐pecking. Generalization gradients were displaced away from the stimulus associated with the lower rate of key‐pecking. Another group of pigeons had similar training, except that a low rate of key‐pecking was established in a stimulus with a much higher frequency of food reinforcement. In this case, the generalization gradients were not affected by the training on the schedule producing a low response rate. 1968 Society for the Experimental Analysis of Behavior
