Two competitive percepts are produced from a bistable stroboscopic motion display. Element or end-to-end motion responses are obtained when the two inner, spatially overlapping elements are seen as stationary and the third element moves back and forth from one end to the other end. Group motion responses are obtained when the three elements are seen to move back and forth as a group. The dominance of these two percepts was controlled by the manipulation of 1) element size, 2) stimulus frame duration, 3) interstimulus interval, and 4) viewing conditions. Both element motion responses and visual pattern persistence decrease as each of the parameters increase in both binocular and dichoptic presentations. By maximizing pattern persistence substantial element motion responses were obtained binocularly and dichoptically.
