Modification of stereotypic behavior in rhesus monkeys using videotapes, puzzlefeeders, and foraging boxes

Results of this study demonstrate that foraging boxes and puzzle feeders can reduce stereotypic behavior significantly [in single-housed subjects]. Audiovisual stimuli through videotapes were also useful environmental tools; however, some stereotypic behavior continued.

Influence of cage size on heart rate and behavior in rhesus monkeys

In single-housed subjects there were no significant differences in basal heart rates or activity counts as a function of cage size [of barren, single cages].

Heart rate and activity of rhesus monkeys in response to routine events

Adult female rhesus macaques responded with a significant, protracted increase in heart rate to being placed in transfer boxes while their dirty cages were replaced with clean ones. The mean heart rate remained elevated for two hours after completion of...

Adult female rhesus macaque responses to novel objects

At least half of the [single-housed] subjects used each of the objects presented [plastic ball, ring and block]. The large behavioral variation both within and between monkeys suggests individual preferences for objects, and indicates the need for long-term evaluation on...

Evaluation of attempts to enrich the environment of single-caged non-human primates

A review of early studies of enrichment for single-housed primates. Our experience with cage toys suggests that after a very short time (a few days or less), most macaques will lose interest in the objects that are offered. Rhesus macaques...

Enriching the lives of captive primates: issues and problems

Discussion of the concept of 'psychological well-being'. For troop-living primates such as rhesus monkeys, the best way to promote their well-being in the laboratory may be to rear them with partners or in social groups. ... Before we conclude that...

Psychological well-being of primates in captivity

Recent amendments to the Animal Welfare Act will, upon taking effect, require that researchers who maintain nonhuman primates in captivity house their animals in such a way as to “promote their psychological well-being.” Unfortunately, no consensus presently exists in terms...
