Figure 4
Determinants of CoG fixations and peripheral void fixations. The mean proportion of fixations (a) and mean proportion of first fixations (b) within a trial, depicted separately for the different conditions and different types of fixations (stimulus fixation versus central void fixation versus peripheral void fixation). Error bars depict 1 SEM and may not be visible when the SEM is very small.
