Document Summary

Motion after effect (mae): illusion of motion of stationary object that occurs after prolonged exposure to moving object. After viewing motion in constant direction for sustained period of time (at least 15 seconds) see any stationary objects that we view subsequently as moving in opposite direction: caused by opponent processes for motor detection. Apparent motion: illusory impression of smooth motion resulting from rapid alternation of objects that appear in different locations in rapid succession. Exner set up contraption that would generate electrical sparks separated from each other by very short distance in space and time. Even though there were 2 separate sparks observes said they saw single spark. Although apparent motion turns out to be win for motion detection circuit, 2 more of classic perceptual. Aperture: opening that allows only partial view of object. Correspondence problem: problem faced by motion detection system of knowing which feature in frame 2 corresponds to particular feature in frame 1.
