Exploring the flicker effect: the influence of in-flight pulsations on saccadic control.
The pulsating illumination of visual display units is known to induce systematic changes in saccade extent. In two experiments reported in this paper, we further examined this effect, by looking at the location of pulsations relative to saccade onset. Both saccade extent and velocity were shown to increase as a function of the number of 'in-flight' pulsations. This result indicates that part of the so-called 'flicker effect' originates during the saccade itself. From a more general point of view, the present data suggest that saccadic control can be modulated by intra-saccadic visual stimuli.
