Positive reinforcement training moderates only high levels of abnormal behavior in singly housed rhesus macaques

It is unlikely that a practical application of human interaction or training will be effective in replacing conspecific social housing with regard to its benefit on abnormal behavior.

Habituation and desensitization as methods for reducing fearful behavior in singly housed rhesus macaques

Operant conditioning using positive reinforcement techniques has been used extensively in the management of nonhuman primates in both zoological and laboratory settings. This research project was intended to test the usefulness of counter-conditioning techniques in reducing the fear-responses of singly...

A psychologic wellbeing response plan for nonhuman primates

Under animal care situations that conform to compliance standards for environmental enrichment established by the Animal Welfare Act (AWA) and the Guide to the Care and Use of Laboratory Animals, at least 10% of laboratory macaques exhibit abnormal behavior, with...

A rational approach to enriched nutrition for nonhuman primates

Obesity is a concern with nonhuman primates (NHPs) housed in captivity for extended periods of time, mostly due to overfeeding and lack of exercise. This is often compounded by environmental enrichment programs that include different types of food. That is...

Effects of positive reinforcement training on infant behavioral development in nursery-reared rhesus macaques (Macaca mulatta)

At the California National Primate Research Center, one key to long-term success of macaque breeding colonies is to develop effective infant-rearing strategies that minimize the emergence of behavioral pathologies, which can be one indicator of welfare. Positive reinforcement training (PRT)...

Stereotypic behaviors in singly housed rhesus macaques are significantly reduced during aquarium viewing

There was no habituation to the fish tank [1 hour per day for five days per week] during the 4-week exposure. We suggest that viewing aquaria containing fish can reduce stereotypic behavior in rhesus macaques.

Wood as an enrichment device for primates

Our facility houses approximately 300 cynomolgus macaques. Providing stimulating environmental enrichment for them without unreasonably increasing staff time can be challenging. Our current enrichment program includes multiple toys, mirrors, forage trays, sound machines, music, videos, and a variety of fruits,...

Acclimation and positive human interaction as methods to facilitate handling and reduce stress in captive cynomolgus monkeys (Macaca fascicularis)

Positive reinforcement training in rhesus macaques – training progress as a result of training frequency

Positive reinforcement training (PRT) efficiency was examined as a function of training frequency in 33 pair- or triple-housed female rhesus macaques. The animals were trained three times a week, once a day or twice a day, using PRT and a...

Operant training differences between male and female group-housed nonhuman primates

Our study group consisted of 16 male (2.24-2.80 kg) and 16 female (1.96-2.91 kg) Chinese cynomolgus macaques (Macaca fascicularis), 2.5-3.5 years of age, that were housed in groups of 4. Our goal was to train the animals to come to...
