Early life experiences: Activity levels and abnormal behaviours in resocialised chimpanzees

It is concluded that human rearing, either alone or with conspecifics, influences behaviour through suppression of normal activity levels as a result of separation and elevation of levels of abnormal behaviours as a mechanism for coping with maternal loss and...

Survey of NIH-Funded Investigators Who Use Nonhuman Primates

Current use of nonhuman primates: 58% Rhesus macaques, 10% Long-tailed macaque, 10% Baboons, 7% Pig-tailed macaques, 4% Squirrel monkeys, 3% Chimpanzees, < 2% Other species. Respondents' most common recommendation for meeting future nonhuman primate needs deal with increasing the availability...

The effect of music on the behavior of captive chimpanzees (Pan troglodytes)

Results suggest music has a significant effect on behavior of captive chimpanzees. It resulted in decreased aggression and active exploratory behavior and increased inactive resting and social behavior (principally social grooming). These effects were predominant for adult males during morning...

From laboratory to more natural enclosures: Maintaining the well-being of captive chimpanzees (Pan troglodytes)

Chimpanzee well-being, as expressed through species-typical behaviors, was maintained in the transfer from a laboratory to a more natural zoo environment. An increase in social and manipulative behaviors was noted in the more natural environment.

Inter-group variation in abnormal behavior in chimpanzees (Pan troglodytes) and rhesus macaques (Macaca mulatta)

It is suggested social learning processes are involved in the propagation of these behaviors.

Positive reinforcement training as a technique to alter non-human primate behavior: Quantitative assessments of effectiveness

We found that positive reinforcement techniques alter the expression of affiliative behavior in group-housed, female rhesus macaques. ... We found a statistically significant reduction in aggression when meals were fed to group-living chimpanzees using a co-operative feeding technique. .... We...

Responses to novel foods in captive chimpanzees

Since novel stimuli provide sensory stimulation and elicit exploration and social interest, occasional presentation of novel foods could be a promising and cheap device for feeding enrichment.

Tool use task as environmental enrichment for captive chimpanzees

Wild chimpanzees spend 50-80% of their time foraging, using tools and other forms of manipulation, while captive chimpanzees cannot. In this study, a device that elicits tool use was presented to six captive chimpanzees housed in pairs. The task successfully...
