Socially-mediated learning in groups of primates: models and methods

An ethological understanding of a behavioral phenomenon incorporates four levels of explanation: development, mechanism, function, and evolution. The phenomenon of socially-mediated learning has garnered a great deal of attention from ethologists, prominently including primatologists. Gregarious primates often exhibit specific behaviors...

Triadic postconflict affiliation in captive chimpanzees: does consolation console?

Consolation is a triadic postconflict interaction between a conflict participant and an uninvolved third party. We tested whether consolation alleviates postconflict stress in captive chimpanzees, Pan troglodytes. In addition, we examined whether consolation is a substitute postconflict interaction for reconciliation.We...

The poor contribution of chimpanzee experiments to biomedical progress

Biomedical research on captive chimpanzees incurs substantial nonhuman animal welfare, ethical, and financial costs that advocates claim result in substantial advancements in biomedical knowledge. However, demonstrating minimal contribution toward the advancement of biomedical knowledge generally, subsequent papers did not cite...

Promoting positive interactions between chimpanzees (Pan troglodytes) and caregivers

We tested our contention that when caregivers use chimpanzee behavior, more positive interactions result.

Species-specific behaviors

The relationships between captive non-human primates and their caregivers are critical to animals welfare. One method to mitigate the potential negative effects and to promote positive relationships is for caregivers to employ species-specific behaviors in their interaction with their charges....

Note on effects of a daylong feeding enrichment program for Chimpanzees (Pan troglodytes)

This study is designed to determine whether longer feeding opportunities over the course of a day would directly engender longer feeding times. A liquid dispenser was presented for 8 h/day to five chimpanzees. The daily feeding duration was increased to...

Components of an animal training program at a large institution

The application of positive reinforcement training (PRT) has increased in zoological, laboratory, and research settings in recent years, however there is little literature pertaining to the development and implementation of such programs. Over the past year, Yerkes National Primate Research...

Effects of short- and long-term changes in spatial density on the social behavior of captive chimpanzees (Pan troglodytes)

The purpose of this study was to test the conflict-avoidance and tension-reduction models by examining the effects of both short-term (1-2 days) and long-term (6 months) changes in spatial density on social behavior in 23 adult captive chimpanzees (6 males,...
