Fig. 1

Initial adaptation rates scale with error size, yet saturate to an invariant response magnitude. a Illustration of experimental apparatus and task structure for Exp. 1. b Schematic view of clamped visual feedback paradigm, in which the angular path of the cursor is independent of hand movement direction. c, d Behavior for all groups (n = 12 per group), divided into two panels for visualization purposes. The small clamp groups (c) demonstrate adaptation rates which scale with error size, whereas the large clamp groups (d) show saturated responses. e Segmented regression indicates that the initial adaptation rate scales between 0° and 4.4° before saturating for all errors above this break point (dashed vertical lines represent 95% CI). f Sensorimotor aftereffects, measured during the first cycle following the clamp block. Dots are individuals; shading and error bars denote SEM. Gray shading denotes cycles without visual feedback
