Kinesthesia task. (a) Scatter plot of age versus baseline initial direction error (IDE) (black circles) and variability of IDE () (grey circles). (b) The baseline IDE across the three intervention groups at pretraining (white), posttraining (light grey), and follow-up (dark grey). (c) The peak speed ratio (PSR) across the pretraining, posttraining, and follow-up in the three intervention groups.
