David J. Lewkowicz is a Professor of Psychology at Florida Atlantic University and an internationally recognized authority on infant perceptual development and the effects of early experience on the growth of the mind. His studies probe babies' perception of the social world and how everyday experience shapes their understanding of this world. He challenges the conventional view that babies learn in a gradual manner by showing they start life with knowledge of one kind, and that by their first birthday, they end up with knowledge of another kind.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
