20Goal-directed aiming movements are planned and executed so that they optimize speed, 21 accuracy and energy expenditure. In particular, the primary submovements involved in manual provided advance information about stylus mass for the upcoming trial while others were not.
38The blocked and random trial orders had minimal impacts on end point aiming performance. 39 Furthermore, similarities in the times to key kinematic landmarks in the trajectories of the 40 random order groups suggests that recent trial experience had a greater effect on the upcoming 41 aiming movement compared to advance task knowledge.
