Laboratory assessment of temperament and environmental enrichment for rhesus monkey infants (Macaca mulatta)

Results indicated that enrichment [for infants who were separated from their mothers] was associated with higher scores on subsequent problem-solving and motor tests.

Enrichment devices for nonhuman primates

We will describe [and discuss] a number of different classes of enrichment devices that have been used at our institution or at other primate facilities. ... Sanitation is probably the most time-consuming aspect of enrichment.

Technical note: A primatrail or an inexpensive cage expansion for group housing small primates

An inexpensive method for converting standard laboratory cages into colony units for housing small primate species is described. In addition to increasing the volume of space available to the animals, this system also provides a complex of climbing, running, jumping,...

Rearing infant monkeys (Macaca nemestrina) in pairs produces deficient social development compared with rearing in single cages

Many scientists and colony managers assume that social housing is a beneficial living condition for all captive primates. Several older studies of primate development question the generality of this assumption. We recently tested this assumption by comparing the social development...

Environmental enrichment for Macaca fascicularis: Effects of shape and substance of manipulable objects

The ring was the most effective shape and the translucent flexible plastic was the most effective substance. Some abnormal self-directed behavioral patterns decreased significantly in the presence of manipulable objects. [Age of animals is not indicated.]
