Comparison of gestures (two hands—whole) by success with Pearson’s chi-squared test of independence χ² (DoF = 1, N = 18). Bonferroni p-value p < 0.05/3 = 0.017 *, p < 0.001 **.

Success// Completion Time	18	19	20
18. Spread using both hands	-	0.000 **	0.003 *
19. Join using both hands	0.000	-	0.000 **
20. Rotate using both hands	0.000	0.004	-
