Perception and action are inextricably linked: Perception provides information to guide action, and action generates new information for perceptual systems. My research addresses how people gather and use perceptual information to guide motor actions and engage in social interactions. Moment-to-moment shifts in goals place ever-changing demands on visual attention. Using a novel head-mounted eye-tracking methodology, I measure eye gaze in infants, children, and adults to investigate the real-time acquisition of visual information during spontaneous, self-generated action. Of particular interest is how characteristics of the body constrain how observers access the visual world and how these visual constraints change over the course of development and alter opportunities for learning.
