The purpose of this study was to test the influence of social isolation during infancy on learning behavior in rats. Rats, reared isolated (n = 55) or paired (n = 60) for a period of 50 days following weaning, were tested on different learning tasks in an operant conditioning chamber. Isolation rearing produced significantly better learning when the training period directly followed the different housing conditions. After a 28 day period of social isolation for the subjects raised paired during infancy no differences in learning between isolated and paired reared animals could be observed. The differences are discussed in relation to the effects of stimulus deprivation.
