Abstract
Two groups of rats were trained in a horizontal-vertical discrimination in a modified Grice box after either 100% or 50% reinforcement for 200 jumps to a single gray stimulus. A control group received only the discrimination. Animals receiving 100% reinforcement in the jumping situation discriminated more quickly than did the controls or those receiving 50%. Results supported those of Purdy and Cross (1979) and strengthened the case for R-S* expectancy learning (Bolles, 1972, 1975). Additionally, these data indicate that R-S* learning can generalize.
