What Babies Know

What do infants know, and how does the knowledge that they begin with prepare them for learning about the particular physical, cultural, and social world in which they live? Answers to this question shed light not only on infants but on children and adults in all cultures, because the core knowledge possessed by infants never goes away. Instead, it underlies the unspoken, commonsense knowledge of people of all ages, in all societies. By studying babies, researchers gain insights into infants themselves, into older children’s prodigious capacities for learning, and into some of the unconscious assumptions that guide our thoughts and actions as adults. To share these insights, the author distills the findings from research in developmental, comparative, and cognitive psychology, with excursions into studies of animal cognition in psychology and in systems and cognitive neuroscience, and studies in the computational cognitive sciences. Weaving across these disciplines, she paints a picture of what young infants know, and what they quickly come to learn, about objects, places, number, geometry, and people’s actions, social engagements, and mental states.
