Mean residual error against mean perturbation size, for Low-uncertainty (blue) and High-uncertainty (red) trials.

<p><i>A:</i> Group mean residual error against mean perturbation size. Error bars are SEM between subjects. Fits are are linear regressions to the mean data. <i>B:</i> Each panel reports the mean residual error against mean perturbation size for a single subject, for Low-uncertainty (blue) and High-uncertainty (red) trials. Error bars are SEM between trials. Fits are linear regressions to the individual data. For both panels each subject’s data have been shifted so as to remove the mean residual error for the 0 perturbation condition for that subject.
