The Psychophysics of Make-up Changes in Female Faces

Perception and evaluation of photographed faces are linked to psychophysical properties such as spatial frequencies. One measure of the distribution of these frequencies is the slope of a function in a log-log plot of radially average Fourier power spectra. An ERP study of face learning has shown that digitally modified faces with shallower Fourier slopes (enhanced high spatial frequencies) elicit larger N170 and N250 amplitudes (Blickhan et al., 2011). Additionally, such faces are behaviorally preferred by raters (Menzel et al., 2015). In everyday life, people use facial cosmetics to change their appearances, which can lead to more female-looking (Russell, 2009) and younger-looking (Jones et al., 2015) faces. Here, we analyzed a dataset of paired photographs from 45 women (with and without self-applied make-up; Jones et al., 2015). The analysis revealed a systematic shallower Fourier slope (enhanced high spatial frequencies) for photographs of women with make-up (-3.16) as compared with photographs of the same women without make-up (-3.25); t(44) = -3.170, p = .003. A shallower Fourier slope in face photographs – as generated by the application of make-up – can lead to a better face learning and higher ratings for subjective attractiveness. The specific neural circuitry modulated by these psychophysical and perceptual changes remains to be determined.
