The Social Development Lab conducts both basic and applied research focused on infant through preschool children’s social and emotional development. Despite America being a land of great wealth, many American children live and grow in stressful, unstable, and sometimes hostile environments. Stress placed on neighborhoods and families by economic hardship, drugs, the threat of violence, and societal injustice (e.g., high incarceration rates) leave many children in tenuous situations in which to receive and/or feel nurture. The Social Development Lab focuses on how these situations influence the way young children feel and think about their social worlds. We are particularly interested in helping support families with infants and toddlers and helping support early childhood classrooms.
