marginally significantP = 0.058
A two-way repeated-measures ANOVA (Sex×Kissing) revealed only a significant main effect of Sex for average spectral power at the individual maximum, F(1,28) = 4.6, P<0.05, η 2 = 0.14, and a marginally significant main effect of Sex for average spectral power across 60 Hz, F(1,28) = 3.9, P = 0.058, η 2 = 0.12, indicating a higher spectral lip EMG power in women than in men.
