Table 4. Summary statistics and Wilcoxon rank sum test for one-second summed distance in competitive condition.

Body Region	Synchrony	Pseudosynchrony	Wilcox.test
Head (n = 38)	M = −0.006, SD = 0.136	M = 0.021, SD = 0.083	W = 633, p = 0.36
Left Hand (n = 36)	M = −0.093, SD = 0.118	M = 0.017, SD = 0.104	W = 342, p < 0.001
Right Hand (n = 35)	M = −0.107, SD = 0.163	M = 0.016, SD = 0.125	W = 386, p = 0.007
Total (n = 34)	M = −0.108, SD = 0.158	M = 0.025, SD = 0.125	W = 330, p = 0.002

Table 4 shows the mean and standard deviation of the synchrony and pseudosynchrony scores for the one-second summed distance in the competitive condition for each body region, as well as a Wilcoxon rank sum test to check whether there is a statistically significant difference between synchrony and pseudosynchrony pairs. If participants had missed some but not all data for a body region, then we excluded that body region, but kept the other two regions for analyses. For example, if Participant 1 had dropped tracking for the first 30 seconds of the left hand, only the synchrony scores for the right hand and head would be recorded.
