THE EFFECTS OF DIFFERENTIAL EARLY EXPERIENCE UPON LEARNING, PERFORMANCE, AND BIOCHEMICAL RESPONSES OF NONHUMAN PRIMATES (RHESUS MONKEYS).
Abstract
A study was made to determine the effects of differential early experience upon learning, performance, and biochemical correlates of stress. Twenty-eight male rhesus monkeys from two to four months of age were used for this research. Four social rearing conditions were utilized as follows: (1) strict isolation (2) partial isolation (3) normal laboratory conditions and (4) enriched environment. The study indicated that differential social rearing conditions did not produce differences of performance in animals subjected to extensive match-to-sample training under positive and negative reinforcement conditions. However, the results of this exploration lend support to the hypothesis that biochemical measures constitute an important supplement to the already existing wealth of behavioral data involving various types of stress in nonhuman organisms.
