PS262 Lecture Notes - Lecture 8: Akinetopsia, Biological Motion, Illusory Motion
Document Summary
Optic flow: as a person moves forward, objects move relative to the person in the opposite direction. A p pa r e n t moti. Mot sees movement in the opposite direction when viewing a stationary stimulus immediately afterward. f all. W a ter moving in one direction, such as a waterfall. Viewing the waterfall makes other objects appear to move in the opposite direction. Optic array: the structured pattern of light created by the presence of objects, surfaces, and textures in the environment. dist. Lo cal environment, so that the stationary background is covered and uncovered by the moving object. Gl o b al o p tic f l o w : information for movement that occurs when all elements in a scene move. Excitation and inhibition are arranged so that movement in one direction creates inhibition that reduces or eliminates neural responding, whereas movement in the opposite direction creates excitation that enhances neural responding.
