Description
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.
