Classes of motor patterns. (A) Left: classification of individual trials was based on the degree of time spent in the shape center (left, small black shape) and in the contour vicinity (left, blue buffer between the inner and outer guiding shapes) (see “Materials and methods”). x–y plots of CF trials (left, blue) and SC trials (left, red) are depicted. Right: probability (y-axis) of the time spent in the contour vicinity (x-axis) based on whether the shape center was crossed or not. (B) CF trials were sub-classified as ‘Linear’ (left) ‘Oscillating’ (middle) or both (right). (C) Examples of various manifestations of SC trials; common scale bar (C, right) for all panels. (D) Distributions (medians and quartiles) of four kinematic variables across all CF and SC trials (p < 0.001 for all differences). N_subjects = 11; N_Sessions = 51 (4–5 sessions per participant); N_trials = 1196. N_{CF trials}: 537. N_{SC trials}: 659.
