PSY 311 Lecture Notes - Lecture 6: Optical Flow, Motion Perception, Retina
Document Summary
Ecological approach to perception: focuses on how perception occurs in the environment by, movement of a person through the environment. Identifying info that the moving observer uses: before 1950s, stationary observer stimulus flashed on screen, thought perception info were on retina only not in the environment, gibson 1950s, how pilots land planes. As you move through the world, the objects within the visual environment flow around you: the human visual system can determine your current direction of travel from the movement of these surfaces. Motion: functions, understand events in environment, attracts attention (attentional capture, provides info about objects, real motion, physical movement of a stimulus. Induced motion appear in different locations: when motion of one object causes a nearby stationary object to appear to move, motion aftereffect. Illusion that occurs after a person views a moving stimulus and then sees movement in the opposite direction when viewing a stationary object: real & apparent motion, rely on similar brain mechanism.
