Most of the research on environmental enrichment has been carried out on non human animals.

This is also known as environmental enrichment.

A contrary point of view is that for environmental enrichment to be considered successful, it should promote only positive behaviours.

Enclosures in modern zoos are often designed to facilitate environmental enrichment.

A range of methods can be used to assess which environmental enrichments should be provided.

In previous work, environmental enrichment has been used to determine its effect on brain activity.

In a study performed by Fan et al., the effects of environmental enrichment on gerbils were tested.

This work led in 1962 to the discovery that environmental enrichment increased cerebral cortex volume.

Part of the effect of environmental enrichment is providing opportunities to acquire motor skills.

Rats raised with environmental enrichment have 25% more synapses than controls.
