Effects of Restricted Rearing on Lashley Stand Performance

Abstract
Rats were reared from weaning to adulthood in either an isolated or enriched environment. Their efficiency at solving a visual discrimination on the Lashley jumping stand and their emotionality were measured as adults. Differences in efficiency of discrimination were slight. Isolated Ss were more timid during the early phases of the experiment but this timidity was reduced by the end of training.
