Effect of light ON stimulations compared with OFF on the time to goal (left), Dt (center), and maximal speed (right). Time to goal: no interaction between light and group conditions: F(1,13)= 1.73, p = 0.17, but paired two-sided Wilcoxon signed-rank test in the Jaws group: W(8)= 5, p = 0.04, Δ = 2.40 s; Dt: interaction between light and group conditions: F(1,13)= 5.57, p = 0.03, paired two-sided Wilcoxon signed-rank test in the Jaws group, W(8)= 3, p = 0.0195, Δ = 0.17 s; maximal speed: interaction between light and group conditions: F(1,13)= 5.43, p = 0.03, paired Student’s t test, T(8)= 3.04, p = 0.016, Δ = -4.81 cm s−1). Horizontal bars represent means.
