ABSTRACT
Fundamental frequency ( fo) is the most perceptually salient vocal acoustic parameter, yet little is known about how its perceptual influence varies across societies. We examined how fo affects key social perceptions and how socioecological variables modulate these effects in 2,647 adult listeners sampled from 44 locations across 22 nations. Low male fo increased men's perceptions of formidability and prestige, especially in societies with higher homicide rates and greater relational mobility in which male intrasexual competition may be more intense and rapid identification of high-status competitors may be exigent. High female fo increased women's perceptions of flirtatiousness where relational mobility was lower and threats to mating relationships may be greater. These results indicate that the influence of fo on social perceptions depends on socioecological variables, including those related to competition for status and mates.

Previous studies have used self-ratings or strangers' ratings to assess men's attractiveness and dominance, attributes that have likely affected men's access to mates throughout human evolution. However, attractiveness and dominance include more than isolated impressions; they incorporate knowledge gained through social interaction. We tested whether dominance and attractiveness assessed by acquaintances can be predicted from (1) strangers' ratings made from facial photographs and vocal clips and (2) self-ratings. Two university social fraternities, their socially affiliated sororities, and independent raters evaluated men's short- and long-term attractiveness, fighting ability, and leadership ability. Ratings made by unfamiliar men using faces, but not voices, predicted acquaintance-rated fighting and leadership ability, whereas ratings made by unfamiliar women from faces and voices predicted acquaintance-rated short- and long-term attractiveness. Except for leadership, self-ratings aligned with peers' evaluations. These findings support the conclusion that faces and voices provide valuable information about dominance and mate quality.
