A comparison of the effects of simple versus complex environmental enrichment on the behaviour of group-housed, subadult rhesus macaques

Enrichment of the environments of captive primates is currently of interest as both a basic and an applied research question, particularly when social and inanimate enhancements are used simultaneously. We measured the hehavioural effects of two intensities of inanimate enrichment...
