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...

The effects of age, sex, rearing history and social group composition on the social behavior of captive chimpanzees (Pan troglodytes) during the introduction to unfamiliar partners and formation of new social groups

Results imply that successful group formation may not be hampered by aggression but by failure for chimpanzees to form affiliative social relationships.

A stereo music system as environmental enrichment for captive chimpanzees

Music was associated with a significant decrease in agitated/aggression and active/explore behaviors during the AM hours [feeding and cleaning time]. .. At these times, we suggest music can be beneficial as an environmental enrichment. When colony activities are relatively low,...

Customizing an environmental enrichment program for captive chimpanzees (Pan troglodytes) at the Primate Foundation of Arizona

This study considers the effects of age, sex, rearing, and group composition on the use of enrichments. .. Subjects included 75 socially-housed captive chimpanzees (40 females, 35 males). .. Results suggest age, sex, and social group composition all had a...

Using positive reinforcement training techniques to facilitate the collection of semen in chimpanzees (Pan troglodytes)

Positive reinforcement training techniques were used to train 7 socially-housed, adult male chimpanzees to voluntarily provide semen samples. .. Subjects had been previously trained to present their ventrums for inspection, and this behavior was modified to include the insertion of...

Leaf-pile pulling: An unusual play pattern in wild chimpanzees

Play in nonhuman animals has generally been viewed as being uniform among study sites. No studies have examined whether there are local variations in play. In this work we report an apparently locality-specific form of play that is basically solo...
