Past research addressed to the minimum temporal separation necessary for the judgment of visual stimulus order has failed to control peripheral adaptation and masking effects. The present study employed pairs of brief stimuli with each member presented to a separate eye; that is, dichoptic presentations. Under these conditions, minimum separations for the correct discrimination of order were found to be far less than those obtained in experiments in which both stimuli were presented to the same eye or to both eyes.
