Lessons From Infants: 1960-2000.

Our image of the infant as an organism interacting with the environment has changed dramatically in the past 40 years. A new surge of infancy research began in the 1960s and continues unabated today. The view of the infant has been transformed from that of a primarily reflexive organism to a highly competent being, exquisitely sensitive to sensory and perceptual information. Controversy still swirls around the issue of when infants acquire specific knowledge about objects and events. New work is reviewed on how infants and toddlers use knowledge to guide their behavior in challenging situations. Despite the tremendous growth of knowledge about infant development over the past 40 years, it seems that we are on the threshold of even more exciting discoveries.
