Experiment 1. Indicators of performance in the position matching task: difference between the heights reached by the two hands (left (L) hand – right (R) hand) with respect to the loading conditions (x axis) averaged over the three target positions. Top row: symmetric loading conditions (LC1 and LC2). Bottom row: asymmetric conditions (LC3 and LC4). All the panels show the population results (mean value ± SE). Panel a bias-error. The dashed line indicates no difference between the two hands (i.e., the desired performance). Panel b variable-error. * indicates statistical significance: * p < 0.05, ** p < 0.01 and *** p < 0.001
