Kinematics of head-unrestrained gaze shifts and arm movements during reaching. A: average displacement profiles of gaze shifts (i.e., eye, head, and gaze) and arm movements for a single subject (32CT), split by target displacement (30° and 40°). Displacement profiles are time-locked to time of target appearance. Shaded areas are SD across trials. B: relationship between reaction time and target displacement. We binned movements based on target displacement for each trial and then computed the average reaction time per bin separately for each subject. Error bars are SE. C: relationship between peak velocity and target displacement. D: relationship between movement duration and target displacement. E: relationship between displacement of the body part and target displacement.
