Document Summary
A condition in which damage to an area of the cortex involved in motion perception causes blindness to motion. Occurs when only a portion of a moving stimulus can be seen, as when the stimulus is viewed through a narrow aperture. This can result in misleading information about the direction in which the stimulus is moving. Apparent motion an illusion of movement that occurs when two objects separated in space are presented rapidly, one after another, separated by a brief time interval. Occurs when stimulus salience causes an involuntary shift of attention. For example, attention can be captured by movement. Most of the experiments on biological motion have used walking humans with lights attached to their joints and limbs as stimuli. In research on movement perception in which arrays of moving dots are used as stimuli, the degree of correlation between the direction of the moving dots.
