- Implicit and Explicit Learning of a Sequential Postural Weight-Shifting Task in Young and Older Adults

Illustration of the center-out movement to a presented radial target (white) and the outcome parameters directional error and homing time. The figure is based on one trial of a young subject at the start (A) and at the end (B) of a practice session. The angle (α) between the two blue lines determines the directional error. The homing time is the time it takes from leaving the dotted circle to stabilizing on the radial target (red trajectory). At the start of the experiment the subject had a larger homing time and a larger directional error than at the end of the practice session (left panel vs. right panel).
