Uncertainty promotes maneuverability.
Group averaged (n = 11) anterior-posterior (AP) center of pressure time series profiles for early (light gray) and late (dark gray) backwards target-jumps. Solid lines are group means and shaded areas are±s.d. Subjects had shorter response times at late versus early target-jump. The maneuverability metric was the response time required for subjects to reverse center of pressure direction in response to a mid-movement backwards target-jump. Bars are the group means±s.e.m. response times for each time point.
