Environmental Enrichment

Outdoor access: The behavioral benefits to chimpanzees

When compared to the results of ameliorative environmental enrichment techniques furnished to the indoor-housed subjects, the small outdoor groups of [two or three] chimpanzees showed broader and more dramatic improvements in well-being. Animals with outdoor access showed significantly less abnormal...

Behavioral effects of simple manipulable environmental enrichment on pair-housed juvenile macaques (Macaca nemestrina)

The teddy bear was preferred as a manipulable toy over the pink teething ring and the green teething ring. Toy use declined with time, indicating that rotation of toys, at least in the short term, may increase use.
