Second, Wilcoxon test between pre- and post-test periods failed to reach significance for both targets (4.63 vs. 4.72; Z = 1.24, P = 0.213), left target (3.73 vs. 4.32; Z < 1), and right target (5.12 vs. 5.10; Z < 1).
For both targets and left target, this Period effect was, respectively, significant and marginally significant in participants n°11 and 12 (χ 2 test; see Figures 3 and 5 ).
In contrast, the rate of express saccades showed an increasing trend between the two periods in five participants for both targets (n°3, 7, 8, 11, and 12; see Figure 3 ) and left target (n°1, 6, 7, 11, and 12; see Figure 4 ), and in four participants for right target (n°3, 8, 11, and 12; see Figure 5 ).
