Frontal emotion/gender, averaged somatosensory activity from the 6 electrodes placed in the frontal region; Dorsal emotion/gender, averaged somatosensory activity from the 6 electrodes placed in the dorsal region, close to the midline; Overall emotion/gender, averaged somatosensory activity from the 18 electrodes placed over frontoparietal regions; r, Pearson's correlation; p, p value (two-tailed); BF_0-, Bayes factor for negative correlation; BF₀₊, Bayes factor for positive correlation; n, sample size.

*p < 0.05 (uncorrected);

**p < 0.01 (significant after correcting for multiple correlations, Bonferroni).
