Background Evolutionary theory suggests that natural selection favors the evolution of cognitive abilities which allow humans to use facial cues to assess traits of others. The use of facial and somatic cues by humans has been studied mainly in western industrialized countries, leaving unanswered whether results are valid across cultures. Methodology/Principal Findings Our objectives were to test (i) if previous finding about raters' ability to get accurate information about an individual by… Expand
Facing our ancestors: judgements of aggression are consistent and related to the facial width-to-height ratio in men irrespective of beards
Abstract Snap judgements of threat based on exposure to the human face were likely maintained throughout history because they facilitated survival when encountering strangers. If an evolvedExpand
Influence of Perceived Height, Masculinity, and Age on Each Other and on Perceptions of Dominance in Male Faces
It is found that increases in perceived height, masculinity, and age (up to 35 years) all increased facial dominance, and the influences of height and age on perceptions of dominance are mediated by masculinity. Expand
Correlates of Non-Clinical Facial Asymmetry and Facial Sexual Dimorphism in a Sub-Saharan African Population
A substantial body of literature has reported on correlates of facial symmetry and facial masculinity/femininity including the role these two traits play in human mate choice. However, major gapsExpand
Beards augment perceptions of men's age, social status, and aggressiveness, but not attractiveness
It is shown that women from two very different ethnic groups, Europeans from New Zealand and Polynesians from Samoa, do not rate bearded male faces as more attractive than clean-shaven faces, consistent with the hypothesis that the human beard evolved primarily via intrasexual selection between males and as part of complex facial communication signaling status and aggressiveness.

First Impressions From Faces Among U.S. and Culturally Isolated Tsimane’ People in the Bolivian Rainforest
The authors examined the generalizability of first impressions from faces previously documented in industrialized cultures to the Tsimane’ people in the remote Bolivian rainforest. Tsimane’ as wellExpand
Individual differences in dominance perception: Dominant men are less sensitive to facial cues of male dominance
Masculine facial characteristics are associated with indices of men's dominance. Previous research found that shorter men were more likely to attribute high dominance to masculine men, suggestingExpand

Individual Differences in Women's Perceptions of other Women's Dominance
Recent research on men's dominance perception suggests that the extent to which men perceive masculine men to be more dominant than relatively feminine men is negatively correlated with measures ofExpand
A sex difference in the context-sensitivity of dominance perceptions
Although dominance perceptions are thought to be important for effective social interaction, their primary function is unclear. One possibility is that they simply function to identify individualsExpand
Facial width-to-height ratio predicts self-reported dominance and aggression in males and females, but a measure of masculinity does not
It is shown that fWHR is related to both self-reported dominance and aggression, but not a measure of facial masculinity, and the facial masculinity index does not predict dominance or aggression. Expand


Criteria of facial attractiveness in five populations

It is shown that age, average features, and (in females) feminine/neotenous features all play a role in facial attractiveness. Expand
Does Human Facial Attractiveness Honestly Advertise Health? Longitudinal Data on an Evolutionary Question
Inspired by the evolutionary conjecture that sexually selected traits function as indicators of pathogen resistance in animals and humans, we examined the notion that human facial attractivenessExpand
Human adaptations for the visual assessment of strength and fighting ability from the body and face
Tests support the hypothesis that the human cognitive architecture includes mechanisms that assess fighting ability—mechanisms that focus on correlates of upper-body strength, and are the first empirical demonstration that, for humans, judgements of strength and judgement of fighting ability not only track each other, but accurately track actual upper- body strength.

The authors investigated accuracy of judging intelligence from facial photos of strangers across the lifespan, facial qualities contributing to accuracy, and developmental paths producingExpand
Testosterone increases perceived dominance but not attractiveness in human males
The authors' data indicate that high testosterone faces reveal dominance, and there is no evidence of directional selection for increased (or decreased) testosterone in terms of attractiveness to the opposite sex, contrary to predictions. Expand
Preferences for symmetry in human faces in two cultures: data from the UK and the Hadza, an isolated group of hunter-gatherers
It is found that symmetry was more attractive than asymmetry across both the cultures and was more strongly preferred by the Hadza than in the UK, implying that symmetry is an evolutionarily relevant trait and that variation in symmetry preference appears strategic both between cultures and within individuals of a single culture.

Female sexual orientation is perceived accurately, rapidly, and automatically from the face and its features
Whereas previous work has shown that male sexual orientation can be accurately and rapidly perceived from the human face and its individual features, no study has examined the judgment of femaleExpand
Genetic Diversity Revealed in Human Faces
Abstract From an evolutionary perspective, human facial attractiveness is proposed to signal mate quality. Using a novel approach to the study of the genetic basis of human preferences for facialExpand

The present data support the supposition that a male's physical strength is also signaled via facial characteristics of dominance and masculinity, which are considered attractive by women. Expand
