For faces, a marginally non-significant positive correlation between attractiveness and FITC was found in experiment 1 (numerically similar to the significant positive correlation with more stimuli as reported in [ 34 ]), and while this pattern was not seen in experiment 3 using the same stimuli and task, the relationships between rated attractiveness and DITC ratings were inconsistent when compared to DEV ratings.

The sentences
The only other correlation which failed to reach significance after Bonferroni correction was the small positive correlation between voice attractiveness and VITC across all speakers (experiment 3). 2 This correlation was no longer significant, however, after Bonferroni correction for the overall 48 tests depicted in figures 1 and 2 (electronic supplementary material, tables S1 and S2). 3 We thank an anonymous reviewer for directing our attention to this point. 4 Following up on a reviewer request, we performed analogous analyses on DEV ratings, as exploratory analyses.
