Облик мужчин, склонных к риску, по данным геометрической морфометрии

Abstract

The article presents the results of a facial anthropometric study suggesting markers of masculinity in motorcycle racers (n = 36), mountain climbers (n = 52), and students (n = 56). The use of geometric morphometrics on the basis of frontal photographs enabled the authors to describe and visualize the facial shapes of men from these three groups, and to reveal significant intergroup differences. Facial shapes of mountain climbers, racers, and students (control sample) were compared pairwise using multivariate regression analysis. The racers and climbers had more masculine facial features compared to the control group: larger, more elongated faces, with a large jaw, thin lips, and narrow eye shape. The differences identified by geometric morphometrics were also confirmed by an additional analysis of facial indices based on linear measurements of certain facial parameters. The findings prove the high efficiency of using a combination of geometric and classical morphometry methods to study full facial shape, as well as to quantify observed differences in certain facial areas.
