Percent of directional deviations obtained at the time of Peak Acceleration, the time of Peak Velocity and the time of Peak Deceleration when the participants performed the movements using (a) left or (b) right arm for each target condition. The gray bars (histogram) correspond to the directional deviation under the CCT condition. The dotted, dashed, and solid lines correspond to ipsilateral (UIP), contralateral (UCL), and center (UCT) targets, respectively, under the uncertain target condition. The thin vertical lines represent the direction of the center target (zero degrees) and the directions of the left (right) targets relative to the center target (approximately 16.5 degrees).
