Cognitive Enrichment in Practice: A Survey of Factors Affecting Its Implementation in Zoos Globally.

Information on the practical use of cognitive enrichment in zoos is scarce. This survey aimed to identify where cognitive enrichment is being used while identifying factors that may limit its implementation and success. Distributed in eight languages to increase global range, responses to this survey ( = 177) show that while agreement on what constitutes cognitive enrichment is poor, it is universally perceived as very important for animal welfare.

Curious creatures: a multi-taxa investigation of responses to novelty in a zoo environment.

The personality trait of curiosity has been shown to increase welfare in humans. If this positive welfare effect is also true for non-humans, animals with high levels of curiosity may be able to cope better with stressful situations than their conspecifics. Before discoveries can be made regarding the effect of curiosity on an animal's ability to cope in their environment, a way of measuring curiosity across species in different environments must be created to standardise testing.
