Example of experimental setup and stimuli for the gaze-contingent task. (a) The participant sees only a small aperture of the face that is centered at the direction of gaze. This aperture moves around on the face in real time as the participant's eyes move. (b) Close-up of the stimuli seen in (a). A circle outlined the area of the screen where the face could be revealed in a gaze-contingent manner. The evenly spaced grid of small dots was included after pilot testing found that it was difficult for pilot subjects to make a saccade to an empty area of the screen.
