Psychological categories as homologies: Lessons from ethology

Abstract

This article takes up the project of studying psychological categories as homologies. Ethologists have numerous theoretical ideas concerning the phylogeny and ontogeny of behavioral homologies. They also have well-developed operational methods for testing behavioral homologies. Many of these theoretical ideas and operational criteria can be applied to psychological homologies. This paper suggests that insights from ethology should be incorporated in adaptationist and functionalist approaches to psychology. Doing so would strengthen those approaches. © Springer Science+Business Media B.V. 2007.
