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 R&D: Quantifying the channel capacity of conscious visual recognition of salient information.
