Abstract

Studies in social perception traditionally use as stimuli frontal portrait photographs. It turns out, however, that 2D frontal depiction may not fully capture the entire morphological diversity of facial features. Recently, 3D images started to become increasingly popular, but whether their perception differs from the perception of 2D has not been systematically studied as yet. Here we investigated congruence in the perception of portrait, left profile, and 360° rotation photographs. The photographs were obtained from 45 male athletes under standardized conditions. In two separate studies, each set of images was rated for formidability (portraits by 62, profiles by 60, and 360° rotations by 94 raters) and attractiveness (portraits by 195, profiles by 176, and 360° rotations by 150 raters) on a 7-point scale. The ratings of the stimuli types were highly intercorrelated (for formidability all rs > 0.8, for attractiveness all rs > 0.7). Moreover, we found no differences in the mean ratings between the three types of stimuli, neither in formidability, nor in attractiveness. Overall, our results clearly suggest that different facial views convey highly overlapping information about structural facial elements of an individual. They lead to congruent assessments of formidability and attractiveness, and a single angle view seems sufficient for face perception research.

Correlations between portraits, profiles, and 360° rotations in perceived formidability (upper line) and attractiveness (lower line). Dashed lines indicate 95% CI.

Differences in mean ratings of formidability (Left) and attractiveness (Right) between stimuli types (portraits, profiles, and 360° rotations). Violin plots show rating distributions, box plots its 25th and 75th percentile. Dark gray violin plots represent female and white violin plots male ratings, respectively. Mean formidability ratings did not differ between sexes, while males rated all stimuli types as more attractive compared to females.

Differences in the mean ratings of attractiveness between device types. Violin plots show rating distributions, box plots its 25th and 75th percentiles. Dark gray violin plot represents mobile phones, light gray violin plot laptop computers, and white violin plot desktop computers, respectively. Asterisks indicate the level of significance, **p = 0.005, ***p < 0.001.
