Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Commentary Type

Invited Commentary


This commentary draws attention to yet another attribute that has been instrumental in demonstrating the cognitive abilities of domestic chicks: lateralization of brain function. The discovery of lateralization in domestic chicks was part of the first evidence showing that humans are not unique in this respect. The effects on cognitive ability of sensory stimulation in critical stages of development have implications for the welfare of chicks, as well as other species.
