Please don’t touch, we’re being enriched! In: Proceedings of the International Conference on Environmental Enrichment

Enrichment often involves manipulation of animals' lives. However, non-interference in their social lives is an important form of environmental enrichment for chimpanzees. Rather than locking the chimpanzees into their indoor cages every evening, an average of 17 hours a day...

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.
