Joseph S. Lappin

Professor of Psychology, Emeritus
Research Professor of Psychology

Lappin conducts research on human visual perception: How does knowledge of the surrounding world_solid objects and meaningful events in 3D spaces_derive from patterns of light on the eyes? Current research projects investigate motion perception, perception of solid shape from motion, peripheral vision, and peripheral vision in children with low vision. Current theoretical research concerns a representational theory of information (for a book tentatively titled Information, form, and knowledge).
