Experiment 2.

a) Mean lateral hand position at the moment the obstacles were passed. b) Mean lateral hand position at the end of movement. c) Mean lateral gaze position at the moment the obstacles were passed. A position to the left of the midline results in a negative value and a position to the right a positive value. d) Mean difference between gaze position and hand position at the moment the obstacles were passed. e) Mean difference between gaze position and hand position at end of movement. Positive values indicate that the fixation position was to the right of the index finger. Error bars depict ± 1 SEM (between subjects).
