Experiment 1. Indicators of performance in the position matching task with respect to the target position: difference between the heights reached by each hand and the target position displayed with respect to the loading conditions (x axis) averaged over the three target positions. Top row: symmetric loading conditions (LC1 and LC2). Bottom row the asymmetric conditions (LC3 and LC4). All the panels show the population results (mean value ± SE). The left hand is represented by a ‘x’ symbol, right hand by a ‘diamond’ symbol. Panel a target-bias-error. The red line represents the target position. Panel b target-variable-error. Colors indicates the loading conditions of the hand: gray is for the lighter weight (250 g) and black for the heavier (500 g). * indicate statistical significance: * p < 0.05, ** p < 0.01 and *** p < 0.001
