Responses to isolated target or cursor perturbations for a single subject. A, Left, Mean force responses (solid line) and SEM (shaded region) across all trials for one exemplar subject to isolated target displacements plotted with respect to the time of displacement onset. The mean force responses were averaged over an early interval (170–230 ms, dark gray bar, middle) and a late interval (370–430 ms, light gray bar, right) for comparison across conditions. Error bars indicate ±1 SEM. B, Mean force responses to isolated cursor displacements.
