Behavioral effects of enrichment on pair-housed juvenile rhesus monkeys (1994)

Schapiro, S. J., Bloomsmith, M. A.

Abstract

Environmental enhancers were frequently utilized, and led to relatively small changes in behavior between control and enriched subjects, suggesting that the presence of a partner for juvenile rhesus monkeys acts as a form of enrichment that may dilute the effects of inanimate enhancements.
