STUDIES ON THE PERCEPTUAL THRESHOLD FOR MOTION. II: EFFECTS OF INDUCED MOTION ON THRESHOLD VELOCITY
Abstract
A proposed method for reducing threshold for perceived motion, by adding the force of induced movement to true movement, was explored. Induced movement was evidenced by (1) subjects reporting movement when no actual movement occurred, and (2) the increase in threshold when the direction of its influence was opposed to actual movement. The predicted threshold reduction, when the direction of actual and induced movement were identical, did not occur, because, presumably, the subjects attempted to compensate for the influence of induced movement.
