^∗∗The correlation is significant at 0.01 level (twofold). ^∗The correlation is significant at 0.05 level (twofold). For all measurements, the number of participants was equal (n = 15). COD, change of direction; AW, attention window; MOT, multiple object tracking; PL, perceptual load; WMC, working memory capacity.
