Abstract
Study of the visual Illusion known as the Pulfrich phenomenon with random dot stereo movies confirms that the filtering of one eye in effect introduces a delay in the system for that eye, which is the probable cause of the illusion. Other features of the illusion suggest that the considerable inertia in the stereoscopic depth process leads to the averaging of several successive frames in each eye.
