Review: Rethinking environmental enrichment as providing opportunities to acquire information

I. Veissier, C. Lesimple, V. Brunet, L. Aubé, R. Botreau

Published in 2024

Scientific overview exploring environmental enrichment, designed to improve the welfare and cognitive abilities of animals in captivity. Enrichment provides animals with the means to acquire information by interacting with their environment, thereby promoting adaptation. This approach suggests that complex and varied environments are more enriching than simply prolonging exposure to stimuli, even if the former are neutral or slightly negative.
