For the first-order disparity training group, the first-order disparity threshold improvement was significantly greater than that in the zero-order disparity [ F (1, 9) = 8.650, p < 0.05, η p 2 = 0.490] and marginally significant than that in the second-order training [ F (1, 9) = 4.597, p = 0.061, η p 2 = 0.338].
