The purpose of the study was to assess the effects of two methods of stimulus presentation (fading and constant) and two response contingencies (delay and no-delay) on the course of discrimination learning; and to examine the effects of response histories on various aspects of discrimination performance. In the fading procedure S- was gradually faded along the dimensions of brightness and time, and in the constant procedure S- maintained a constant value throughout training. Subjects trained with the constant procedure made significantly more S- responses in the course of acquisition than subjects trained with the fading procedure. In the constant-delay procedure, S- responses were followed by a delay in the offset of S-. In the constant-no-delay procedure S- responses were followed by an intertrial interval. Subjects trained with the constant-no-delay procedure made significantly more responses to S- than subjects trained with the constant-delay procedure. The amount of extinction which occurred during learning was highly correlated with intertrial responding and the stability of the learned discrimination. Discrimination reversal learning was also a function of original learning history. The results were discussed in terms of the differential processes which underlie discriminative performance when different training procedures are used. (Author).
