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...

Effects of social manipulations and environmental enrichment on behavior and cell-mediated immune responses in rhesus macaques

In general, enrichment of the inanimate environment with toys, structures, foraging devices, and/or videotapes increased the amount of species-typical behavior expressed by the monkeys, but did not affect their immune responses. Housing monkeys socially, on the other hand, not only...

Training macaques to voluntarily co-operate during two common procedures: Blood collection and capture of group-housed animals

Ten male, pair-housed rhesus macaques (Macaca mulatta) and six female, pair-housed stump-tailed macaques (M. arctoides) were successfully trained to actively cooperate during in-homecage venipuncture. Training was based on positive reinforcement with food-treats and vocal praise, consistent firmness, gentleness and patience....

The myth of the aggressive monkey

Captive rhesus macaques are not intrinsically aggressive, but poor husbandry and handling practices can trigger their aggression towards conspecifics and towards the human handler. The statement 'rhesus macaques are so aggressive animals' is probably based on the fact that basic...
