  1. In the lower left triangle, Fisher’s exact probabilities are shown. In the upper right triangle, partial Spearman’s correlation coefficients are shown. The two triangles are separated by the diagonal line of “–”. Statistical significance is denoted with * if p < 0.003 based on Bonferroni correction. Abbreviations: variability (Varxy), contraction/expansion (Areaxy), systematic spatial shift (Shiftxy), posture speed (PS), reaction time (RT), initial direction error (IDE), speed maxima count (SMC), movement time (MT)
