Positive reinforcement training paired with videotape exposure decreases training time investment for a complicated task in female chimpanzees

Subjects were 10 adult chimpanzees living in two groups. Five females were exposed to a 10-minute videotape of female chimpanzees being positively reinforced for successfully urinating into a cup. Immediately following videotape exposure, these subjects participated in a training session....

Naive chimpanzees’ (Pan troglodytes) observation of experienced conspecifics in a tool-using task

The authors investigated the occurrence of naive chimpanzees' (Pan troglodytes) spontaneous observation of experienced conspecifics during a tool-use task entailing honey fishing. The chimpanzees were presented with 20 kinds of tools of which 12 kinds were usable. Six pairs of...

Rigid plastic balls as environmental enrichment: A novel presentation

At the Primate Foundation of Arizona (PFA), we provide many different types of both destructible and indestructible objects, but seldom provide rigid plastic balls. They are frequently thrown about the enclosure during displays and have damaged the cage mesh. We...

Behavioral intervention program: Enriching the lives of captive nonhuman primates

Since its inception, 142 animals have been reported to the BIP [Behavioral Intervention Program, developed in 1994], including chimpanzees, baboons and other monkeys. The most common behaviors reported were hair pulling, pacing, rocking and self-aggression. 36.6% of the BIP subjects...
