Colwyn Trevarthen, a New Zealander, is Professor (Emeritus) of Child Psychology and Psychobiology at the University of Edinburgh, where he has taught since 1971. He trained as a biologist, and has a PhD in psychobiology from Caltech. While a research fellow at the Center for Cognitive Studies at Harvard in the 1960s, he began research on infant communication that led to the discovery of the innate capacities for human intersubjective communication. His work at Edinburgh in the 1980s on the development of mother-infant interactions pioneered a theory of cultural learning. His published work covers neuropsychology, brain development, infant communication child learning, and emotional health and methods of education and therapy. He is interested in the natural motives and emotions children have for learning in companionship, the effects of disorders such as autism and depressive illness, and how parents and teachers may best support needs of young children.
