Both experiments were within-subject, so all subjects received the treatments shown. A, B, C, and D, different discriminative stimuli (counterbalanced); R1 and R2, lever press or chain pull responses (counterbalanced); +, reinforced; -, nonreinforced. During testing in both experiments, R1 was lower in B than R2 was in C. [See Bouton et al. (256).]
