Fig. 2

Time course of gaze position in the current study (left panel) and in the previous one (right panel). The concealed experiments are displayed on top and the countermeasures at the bottom. The graph depicts the proportion of fixation time directed at familiar (blue) and unfamiliar (yellow) faces (averaged across the 3 unfamiliar faces) during the parallel display. Eye movements outside the interest areas or blinks are presented in gray. Time points with a significant difference (after False Discovery Rate (FDR) correction) between familiar and unfamiliar faces are displayed at the top of the figure as blue or yellow bars for familiarity preference and avoidance effects, respectively. Shadowed area indicates ± 1 standard error (SE) across participants
