Primates: a natural heritage of conflict resolution

The traditional notion of aggression as an antisocial instinct is being replaced by a framework that considers it a tool of competition and negotiation. When survival depends on mutual assistance, the expression of aggression is constrained by the need to...

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...

A few new developments in primate housing and husbandry

A major focus of this paper is an examination of the complementary role that behavioral management strategies play in the establishment and enhancement of well-defined nonhuman primate research resources. .... Additionally, I will discuss the use of positive reinforcement training...
