Abstract:

This project concerned the discovery and description of basic mechanisms of human visual motion and texture perception. Motion and texture are critical inputs to visual perception. Basic mechanisms of motion are of particular interest because they are perhaps the primary substrate for perceptual recovery of 3D depth structures and orientation in space, they are critical for detecting new objects and events in the environment, as well as playing an important role in 2D perception. Motion and texture are considered together here because the problem of discriminating velocity in a one- dimensional motion stimulus is formally equivalent to the problem of discriminating orientation in a texture stimulus the t dimension of the motion stimulus becomes the y dimension of the texture stimulus.
