Reaction time (s)	1.09 ± 0.38	1.24 ± 0.60	0.968	0.340	0.163

Data are expressed as mean (mn) ± standard deviation (SD) or median (md) (interquartil range [IQR]). Between-group differences were calculated by using the independent t-test (t) or the Mann-Whitney U test (U). Significant results are highlighted in bold. ES: r effect size statistics (r = 0.12 small effect; r = 0.20 medium effect; r ≥ 0.32 large effect [74])
