The ANOVA performed on N1 latency values showed that responses to both neutral and distressed faces were significantly faster in women (155.1 ms, SE = 1) than men (162.1 ms, SE = 1) as shown by the significant "gender" factor (F[1,38] = 24.40; p < 0.000001). Furthermore, the effect of "hemisphere X gender" (F[1,38] = 7.12; p < 0.01) proved a strong hemispheric asymmetry in men but not in women; men responded earlier in the right hemisphere rather than the left (see Fig. 2), as confirmed by Tukey post-hoc comparisons.
