Laboratory studies of visual attention emphasize the role of bottom-up and top-down features in influencing how people explore scenes and how exploration changes over development. In the real world, visual exploration also relates to motor factors—how people use eye, head, and body movements to select what they see. In this talk, I will describe how bottom-up, top-down, and motor factors change over development. I will report a series of eye tracking studies (laboratory and naturalistic) that measure eye gaze in infants, children, and adults to investigate the real-time acquisition of visual information during spontaneous, self-generated action and while viewing complex scenes. 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 to alter opportunities for learning.
