Fig. 3

Center of fixation in the free viewing task. The distribution of fixations along the screen’s horizontal axis is depicted as a boxplot diagram, separately for neglect patients and controls as well as for the four different types of modification. The black median band represents the CoF, i.e. 50% of the fixations landed left and 50% right of this position. The boxes span the area from the lower quartile (left end) to the upper quartile (right end) and only 2.5% of all fixations were located outside the whiskers. In neglect patients, the pathological rightward shift of the CoF was significantly reduced under GC-HIGH and GC-LOW as compared to the ORIGINAL version of the picture (*p < 0.05). Further significant between-modification differences are reported in the main text
