Evaluation of two environmental enrichment devices for singly caged chimpanzees (Pan troglodytes)

The television had a less pronounced effect on behavior [reducing behavioral disorders and increasing activity of the single-housed subjects] than the toys.

Interaction between adult male and immature captive chimpanzees: Implications for housing chimpanzees

These observations suggest that captive adult male chimpanzees have the potential to develop affiliative relationships with immature conspecifics. Housing adult males in groups along with infants may be an important way of increasing the social complexity of the males' environments.

Food sharing and reciprocal obligations among chimpanzees

Food sharing has been proposed as the propeller of hominid evolution, particularly of the development of systems of mutual social obligation. Yet, food sharing in our closest relative has never been subjected to a rigorous analysis of reciprocity. Provisioning of...

Resocialization of captive chimpanzees: An amelioration procedure

Group formation protocols are described. 59 of 60 chimpanzees were successfully resocialized to compatible group living. Severe wounding has not occurred in our facility, perhaps due to luck, but more likely due to the close daily behavioral monitoring of each...

Signs of enrichment: Towards the psychological well-being of chimpanzees

By providing the chimpanzees with a wide variety of things to do we have also created an environment that is conducive to interesting social interaction. This is exactly the type of environment one would expect to help a chimpanzee achieve...

Chimpanzees in captivity: Humane handling and breeding within the confines imposed by medical research and testing

The ultimate touchstone for the psychological well-being of chimpanzees should be the ability of formerly singly caged animals to integrate into social groups after release into a (simulated) free environment, such as man-made islands.
