Research Program:  Human perception has limited but selective capacity. My research aims to identify the form and quantity of information acquired by vision. The experimental and theoretical objectives are to identify optical patterns that carry information about the visual world and to measure visual sensitivities to those patterns.  Specific areas of research (> 100 publications) have focused on the span of selective attention, the role of prior knowledge, motion perception, perception of surface shape from motion and stereopsis, perception of 3D space, visual acuities for coherent motion and binocular disparity, visual motion mechanisms, figure-ground segregation of moving patterns, peripheral motion perception in normal and low vision, and the speed of visual processes.  In a contract from the Office of Naval Research, we recently discovered that visual information awareness operates at a limited and quantifiable rate in parallel with other visual processes.
