Abstract
Fixations are briefer when the ensuing saccade is directed upwards. Might visual field visibility differences explain this? Visual search (n=20) for a gaze-contingent target on a blank screen did not eliminate the effect. Also, event-related potentials (n=2) showed greater planning difficulty to look down. The effect does not reflect visibility.
