Abstract : The present experiment examined the effects of environmental enrichment on behavioral measures of locomotor activity, stress, and health in rats. Six measures (i.e., Open Field, Elevated Plus Maze, Light/Dark Box, Plasma Corticosterone, Food Consumption, and Body Weight) were used to examine the effects of enrichment and stress on 48 male, adolescent Sprague-Dawley rats that were placed in an enriched or non-enriched environment for a total of 24 days. Compared with rats housed in non-enriched environments, rats that were housed in enriched environments showed the following: (1) decreased activity and increased habituation in a novel environment; (2) ate less food and had less body weight gain (6% on average). The results regarding stress responses were inconclusive. These findings and future research investigating the effect of environmental enrichment to slow the rate of weight gain are discussed.
