This application is concerned with visual development in early infancy. Our broad, long-term objective is to understand how people develop a stable knowledge or cognitive model of their visual world.
Our specific aims i nclude work on 10 studies of visual scanning in human and rhesus infants that we initiated during the prior grant period. I also propose 10 new studies to: 1) test a provision of a concept that is designed to account for infant visual activity in a wide range of situations; b) study the role of the visual consequences of eye movements in visual organization; c) investigate the development of visual anticipation. Finally, plans to test a practical application of our anticipation work with infants at risk are described. Our method employs infrared corneal-and retinal-reflection video recording of visual fixation sequences over visual displays. Through analysis of the visual scanning records and derived eye-movement parameters, we draw inferences about visual information-acquisition strategies, the task the baby is trying to accomplish, what the infant can see and how (s) he organizes her/his visual world.
