Crowding is immune to the pre-saccadic shift of attention
C Morvan, P Cavanagh
Previous studies have shown that an attentional cue reduces crowding (eg Yeshrun and Rashal, 2010 Journal of Vision). In a series of experiments we examined whether the attentional shift that precedes a saccade (Deubel and Schneider, 1996 Vision Research) also affects crowding. We presented a crowded display in the periphery and had subjects saccade to its center by flashing a saccade cue prior to presenting the display. The display was removed just before the eyes landed so the visual information was only collected from the visual periphery. We found no improvement in the saccade condition compared to the control fixation condition, leaving performance and the critical spacing unchanged. These results indicate that the pre-saccadic attentional shift does not add to the effect of ordinary cueing in relieving crowding.
