This analysis revealed a highly significant group effect (F (1,13) = 12.717, p = 0.003) and a large statistical effect size(partial η 2 = 0.5).

Similarly, the variation of task performance (computed as standard deviation across the 64 movement conditions) showed a trend of reduced variation after training (negative change values in Table 2 ), which was marginally significant only in the case of the end-error measures (F (1,14) = 4.66, p = 0.049, partial η 2 = 0.25).
Although both groups showed a trend towards a within-subject improvement with the task (i.e. reduction in lateral guidance and forward assistance from the robot, and in the end errors; shown as negative change values in Table 2 ) a significant main effect of session was found only for the end-error measure (F (1,14) = 15.4, p = 0.002, partial η 2 = 0.52; Assist : p = 0.43; Guide : p = 0.069).
