The central theoretical question is the study of developmental process and mechanisms of change. The work focuses on early changes in perception, language, and action and how those changes in these areas support each other particularly around the age (12 months to 24 months) that children break into language. The research takes a systems approach, seeking to understand how multiple components interact over nested time scales and levels of analysis and how, in so doing, they yield an individual's developmental path.
