Negative gaze angles represent leftward deviation, and positive gaze angles represent rightward deviation. All three subjects successfully complied with the instruction to look left, right, or forward at the start of each task. P values are shown for comparisons of left and right versus forward (Kruskal–Wallis per subject on instruction with exact Dwass–Steel–Critchlow–Fligner post hoc comparisons).
