Transfer by Normal and Chronic Whole-Body Irradiated Monkeys of a Single Learned Discrimination along a Peripheral Cue Gradient

Abstract

Abstract : Nine normal monkeys, three monkeys with previous focal-head irradiation of the posterior association areas, and two monkeys with previous focal-head irradiation of the frontal association areas were tested for transfer of a simple learned discrimination along a peripheral cue gradient. The results of the study demonstrated that: (1) There was no significant difference in performance between normal and chronic focal-head irradiated monkeys. (2) There was a significant change in performance as a function of degree of spatial separation between the relevant discriminanda and site of food reward. (Author)
