Description
Psych 2E03: Sensory Processes Chapter 9: Perceiving Movement Studying Movement Perception - Real movement: movement occurs when an object moves across an observer’s field of view. Object is physically moving - Apparent movement: not actual or real movement between the stimuli. - Induced movement: illusion that occurs when movement of one object induces the perception of movement in another - Movement aftereffects: occur after viewing a moving stimulus for 30-60 seconds then seeing movement in the opposite direction when viewing a stationary stimulus, ex: waterfall illusion The Functions of Motion Perception - Surviving to perceive another day:  Ability to perceive movement is such a basic mechanism for interacting with the world  Motion agnosia: liquid appears frozen, movements of speaker’s face and mouth, appearance or disappearance of people or objects - Perceiving objects:  Movement accomplishes perception by perceptually organizing elements that had previously not been associated with each other, so it becomes possible to tell what belongs to what.  Our movement relative to objects is constantly adding to the accuracy of our perception of these objects  Kinetic depth effect: movement of an object’s two-dimensional shadow can change the perception of the shadow into the perception of a three-dimensional object  Structure-from-motion: movement can create perceptual structure, the kinetic depth effect is an example of this. The Moving Observer - Not only do objects in the environment move but observers move as well:  Simple case: an object moves, and the observer remains stationary  An object moves and the observer follows the object with his or her eyes  An observer moves through a stationary environment - The behavioural approach: taking environmental information into account:  Identify information in the environment that provides information for perception  Optic array: structure created by the surfaces, textures, and contours of the environment. The way the optic array changes when the observer moves or when something in the environment moves.  Local disturbance in optic array: occurs when one object moves relative to the environment, covering and uncovering the stationary background.  Global optic flow: entire optic array is moving indicating that the observer is moving not the environment. - The physiological approach: the corollary disc
