Tamar Kushnir is an associate professor at Cornell University and the director of the Early Childhood Cognition Laboratory. Her research examines the origins of causal and social knowledge in early childhood, and how children acquire this knowledge through play, observation, and social interaction. Questions include: Do infants use statistical information to learn about other people’s preferences? Do toddlers read social cues to gain valuable information about culture? Do preschoolers consider knowledge and expertise when deciding who to learn from? Do young children understand choice and free will? Do complex causal understandings of mind and self influence children’s social and moral behavior?
