a nonsignificant trendP = 0.097
Reaction time was significantly affected by perturbation level, F(1, 18) = 34.73, P < 0.001, ηp 2 = 0.65, but not by hearing condition, F(2, 36) = 1.64, P = 0.21, ηp 2 = .08, and the interaction showed only a nonsignificant trend, F(2, 36) = 2.49, P = 0.097, ηp 2 = 0.12 ( Figure 5 ). 5.
