SEVERAL RECENT SUHVKYS of the literature (2, 3, 4, 9) reflect the increased emphasis being placed upon study of the relationship between early environment and later behaviour in animals. Learning ability has received particular attention, and several studies have shown that the learning ability of adult animaLs is affected by the quality of their infant environment. More specifically, they indicate that animals raised in "enriched" or "stimulating" environments are superior in adult learning

These results were obtained with animals possessing a normal heritage of learning ability; hence there remains the possibility of differential effects for animals of superior or inferior endowment. The present study was designed to explore this possibility. Its specific object was to test for possible differential effects of enriched and restristed early environments on the problem-solving ability of bright and of dull rats.
