The results of the two-way repeated measures ANOVA for the P300 amplitudes (see Figure 4 ) showed a marginally significant main effect of attractiveness [ F (1, 33) = 3.962, p = 0.055, η p 2 = 0.107], with the P300 amplitudes elicited under the high-attractiveness voice condition ( Mean = 9.947 μV, SD = 0.938 μV) being significantly higher than that elicited under the low-attractiveness condition ( Mean = 9.431 μV, SD = 0.902 μV).
