Abstract

A new apparent motion phenomenon is described. It occurs when two flashing screens are observed binocularly, one screen for each eye, and the temporal phase between the flashes is suddenly changed. It appears as a low-contrast pattern of vertical stripes that move either to the left or right, depending on the phase of the lights. Changing the relative intensity of the screens alters the effect in a manner consistent with previous measurements on visual time delays.
