We also found a marginally significant interaction of Configuration * Race-of-the-stimulus [ F (1, 25) = 3.6, MSE = 37, p = 0.08; partial η 2 = 0.08] and post-hoc analysis revealed that whereas for own-race faces the amplitude of the P3 was larger for normally configured (12.2 ± 2.8 μV) than distorted faces (10.7 ± 3.0 μV; p = 0.008 < 0.01), no such effect was found for other-race faces (13.9 ± 2.8 μV and 13.2 ± 3.1 μV for normally configured and distorted faces, respectively; p > 0.05) and that the ORA-of-P3 was larger for distorted (3.8 ± 1.8 μV) than normal faces (1.5 ± 1.6 μV; p = 0.006 < 0.01).
