The Blanking Effect in Saccadic Suppression of Image Displacement for Isoluminant Target

Abstract

When the visual target blanks for a while immediately after a saccade, saccadic suppression of image displacement is degraded (blanking effect). This suggests that the visual image immediately after a saccade is important to form visual stability. We investigated whether the blanking effect remained when the target was isoluminant with the background. In the luminance condition the blanking effect was confirmed, however in the isoluminance condition the blanking effect diminished. These results suggest that the luminance information has more important role than the color information in forming visual stability across saccadic eye movements.
