Fig. 3

Number of visits and durations in the current study (left panel) and in the previous one (right panel). Each graph depicts the mean duration of visits (consecutive fixations on a specific face before moving to a different face) and their number, separately for familiar (blue) and unfamiliar (yellow) faces. Error bars indicate ± 1 standard error (SE). (**p value < 0.01, ****p value < 0.001 for paired t test comparisons between visits to familiar and unfamiliar faces)
