Implicit adaptation generalizes around the aiming location (30° CCW) Implicit adaptation generalizes around the aiming location (30° CCW). φ denotes generalization, calculated as the proportion of the catch trial magnitudes (Figs. 2-4, green error bars) to the calculated implicit (Figures 2-4, magenta trace). Implicit adaptation generalizes around the aiming location (30° CCW). φ denotes generalization, calculated as the proportion of the catch trial magnitudes (Figs. 2-4, green error bars) to the calculated implicit (Figures 2-4, magenta trace). When plotted as a function of angle relative to the trained target location, the φ values reveal a generalization curve that is centered around the aiming location (blue). Error bars denote the SEM. This is overlaid on fitted Gaussian distributions for the cursor (green; R2 = 0.996), reported aim (red; R2 = 0.969), and hand (gold; R2 = 0.996) angles for all 70 participants during the rotation block. The distributions are normalized to their respective means. Kevin A. Day et al. eneuro 2016;3:ENEURO.0005-16.2016 ©2016 by Society for Neuroscience
