Group Data for Saturation Function, Beauty Stimuli by Stimulus Category.

Quadratic fits for the group data from 77 subjects keypressing for beautiful and average faces. Eight correlations were performed between mean intensity data (K) and the standard deviation of the responses (sigma), stratified by the stimulus condition (BF, AF, BM, AM faces) and valence of keypress (approach, +, or avoidance −). The degrees of freedom for each quadratic correlation were df1 = 2, and df2 = 74. Results are listed for r and the related likelihood (p value or significance).
