  1. Note: The symbols ‘>’ denote that the amplitudes of ERP components evoked by the acoustic stimulus on the left side of ‘>’ are significantly larger than those on the right side, and no significant difference exists among the corresponding conditions on the same side of ‘>’ for each case. The degrees of freedom are shown after the brain regions for the three factors respectively. Note that only significant interactions are shown. p < 0.05, p < 0.001. Abbreviations: F is the F-value from ANOVA; ε, the values of epsilon of Greenhouse-Geisser correction; LSD, least-significant difference test; OC, the original note; SC, the version with each original note reversed (only spectral characteristics remained); TC, the version with white noise enveloped by the original note (only temporal characteristics remained); interact, the interaction between the factors “stimulus” and “sex”
