Discrimination Learning and Inhibition
Abstract
Pigeons learned to discriminate between a white vertical line on a dark background (S+) and a monochromatic circle of light (S-) either with or without responses to S-(errors). Gradients of inhibition, which were centered around S-, and which had greater than zero slopes, were obtained only from those subjects who learned to discriminate with errors. The results indicate that the occurrence of errors is a necessary condition for S- to function as an inhibitory stimulus. This finding is consistent with other performance differences in subjects who have learned to discriminate with and without errors.
