Riviello, M. C. 1995. The use of feeding board as an environmental enrichment device for tufted capuchin monkeys (Cebus apella

Results show that the feeding board [on which seeds were scattered] were almost always in use [during 30-minute observations]. ... There was no evidence that the position in which the feeding board was placed [high...

Brent, L., Weaver, D. 1996. The physiological and behavioral effects of radio music on singly housed baboons. Journal of Medical Primatology 25(5), 370-374.

The response of four singly caged baboons to radio music was measured using behavioral and physiological indices. Heart rate and blood pressure, measured through a tether system, as well as behavior, were recorded during a...

Schapiro, S. J., Suarez, S. A., Porter, L. M. et al. 1996. The effects of different types of feeding enhancements on the behav

Enrichment techniques designed to encourage captive primates to spend more species-appropriate amounts of time in foraging behaviours have been successful. The present study measured the behavioural effects of four feeding enhancements: two devices (mats and...
