Abstract

An attempt was made to determine the effects of successive shifts in the quality of a reinforcing agent upon the acquisition of a brightness discrimination. Two levels of sucrose concentration (4 and 32%) were combined factorially during preadaptation and discrimination phases. Dependent measures included response rate and the number of errors made during discrimination acquisition. Results indicated non-significant negative contrast effects in errors and, in addition, negative contrast and amount of reward effects in terms of response rate. It was hypothesized that the absence of amount of reward effects in errors and positive contrast in both dependent measures was a function of a partial between groups design and ceiling effects respectively.
