Asymmetries in the discrimination of motion direction around the visual field.

Across locations, the difference in sensitivity did not reach statistical significance at the group level (F(1, 5) = 3.355, p = 0.126), but a significant interaction (F(7, 35) = 28.561, p < 0.0001) resulted from opposing effects on and off the primary meridians, confirmed by visual inspection (see Figure 4 B: note the data points are identical but regrouped from Figure 4 A).
