Most broadly, I am interested in the nature, learning, and development of knowledge within the specific domains of socio-cognitive and cognitive development in infancy and early childhood. Areas of interest include: cultural evolution, imitation, theory of mind, infant research methodology, the nativist-empiricist debate and the emergence of new knowledge.
