Experimental task design. The cue turned either red signaling a saccade to the right side or green signaling a saccade to the left side. Each target position was given by a previously flashed target. The subjects prepared thus a rightward saccade (I. red cue), a leftward saccade (II. green cue), first a right- then a leftward saccade (III. red-green combination), or first a left- then a rightward saccade (IV. green-red combination). The offset of the fixation target indicated the start of the memory saccade.
