Table 1 Statistical results.

Results of the comparisons performed using the Wilcoxon test on the absolute value of the passer’s palm position relative to the object (|Pac|) and the absolute distance between the median of the distribution of each condition and the passer’s palm (|dPac|). The P values reported are adjusted according to the Bonferroni correction. Significant results (P < 0.05) are boldface.
