Figure 1

Illustration of an unadapted saccade during the horizontal amplitude reduction condition. (A) Prior to the saccade, the participant is fixating on the item at position F and intends to shift his or her gaze to the item at position T. (B) During the saccade (thin blue arrow), the entire stimulus panel (gray area) is shifted horizontally by half of the saccade’s horizontal amplitude (indicated by the thick blue arrows). Once the participant’s saccade has landed at the intended absolute position T, the intended item will be located at T′, resulting in a horizontal visual error. A corrective saccade, indicated by the dashed arrow, is then necessary to fixate the intended item, which would cause another display shift (not illustrated).
