Indeed, the difference between x and y axis was highly significant for the Matching error and the Variability in the PM condition ( ME : t 17 = −7.46, p < 0.001; V : t 17 = 4.70, p < 0.001) and reached significance for neither ME nor V in the VPM condition ( ME : t 17 = −1.06, p = 0.061; V : t 17 = 0.25, p = 1.000) ( Figure 6 ). 4.
