Learning curves of the averaged parameters (± SD) showing the evolution of a specific parameter over the trials (1 to 10) for the 3 sessions. a Task time (TaskTime, s). b Movement time (MovementTime, s). c Peak velocity (PeakVel, cm/s). d Hand path ratio (HPR, dimensionless). e Number of peak velocity (nPeak). f Game score (Score, %). Between-session significances are represented with asterisks (*p < 0.05; **p < 0.01; ***p < 0.001) and within-session significances are reported in Table 2
