Experiment 3: Activity profiles of left (a, c) and right (b, d) phF5c plotted separately for runs with fixation to the left (a, b) and right of target (c, d). Red outlines indicate regions contralateral to the target, i.e., where the actual grasping takes place in the contralateral hemifield. Vertical bars indicate SE across subjects. The three-way interaction between factors person, action, and fixation position was significant for right phF5c (F1,17 = 17.02, p < 0.001), but not left phF5c (F1,17 = 0.04, p > 0.8). The two-way interaction between action and person factors was significant in all four panels: F1,17 = 6.2, p < 0.025 (a), F1,17 = 35, p < 0.001 (b), F1,17 = 11.3, p < 0.005 (c) and F1,17 = 10.4, p < 0.005 (d), but the response to static hand was strongest in panel B.
