Action timing and variability over the course of learning. Average (a) action timing and (b) action variability over the course of the experiment for the conditions GG (blue) and CG (red). In both conditions the action timing as well as the action variability decline (actions are timed earlier, variability decreases) over time. Both measures were calculated in bins of 5 minutes length. The shaded areas indicate the inter-subject-variability (±1 SEM). The shaded areas indicate the inter-subject-variability (±1 SEM). The black dashed lines indicate the time at which all subjects in condition GG have reached maximum gravity (g_max = 3.5 m/s²) latest. For the purpose of illustration, the curves were smoothed over time using the weighted running average method.
