Self-reported Social Media Use Does Not Affect Cross-Cultural Consensus in First Impressions
Research focusing on first impression formation based on facial stimuli lacks a conclusion on whether there is a cross-cultural agreement and how deeply it has proliferated across distant populations.Social media may play an important role in the level of cross-cultural agreement as they provide us with overwhelming numbers of visual stimuli, including faces.Sharing social media aesthetics, their users may utilise facial cues congruently.We asked…
Physical Strength Is Not Associated With Facial Sexual Dimorphism and Asymmetry in Either Czechs or Cameroonians
OBJECTIVES: Handgrip strength is a widely used indicator of muscle strength and general health, but its association with facial morphology remains unclear. This study examined whether handgrip strength or its asymmetry is related to facial sexual shape dimorphism, perceived masculinity/femininity, and facial asymmetry in two culturally and genetically distinct populations: Cameroonian and Czech adults. METHODS: Geometric morphometric methods were…
Facial basis of stereotypes
Human migration is an increasingly common phenomenon and migrants are at risk of disadvantageous treatment. We reasoned that migrants may receive differential treatment by locals based on the closeness of their facial features to the host average. Residents of Türkiye, the country with the largest number of refugees currently, served as participants. Because many of these refugees are of Arabic origin, we created target facial stimuli varying alo…
Visual attention to faces during attractiveness and dominance judgements
Perception studies describe numerous discrete morphological facial features as important to judgements of various characteristics. Interestingly, little is known about whether people actually direct their visual attention to these features and how specific contexts or sex affect this attention. We, therefore, examined visual attention to faces in the context of intersexual (opposite-sex assessment of attractiveness) and intrasexual (same-sex asse…
Distinctiveness and femininity, rather than symmetry and masculinity, affect facial attractiveness across the world
Sexually dimorphic traits are associated with subsistence strategy in African faces from the Sahel/Savannah belt
OBJECTIVES: Previous research revealed that in some African populations, food-production strategies are associated with facial shape. Nomadic pastoralists living in the African Sahel/Savannah belt have a different facial morphology than their sedentary neighbors. We investigated whether the lifestyle associated with a subsistence pattern has an impact on sexual dimorphism in the facial structure. METHODS: We employed several methods from geometri…
Sexual Dimorphism
Sex-typicality displayed as sexual dimorphism of the human face is a key feature enabling sex recognition. It is also believed to be a cue for perceiving biological quality and it plays an important role in the perception of attractiveness. Sexual dimorphism of human faces has two main components: sexual shape dimorphism of various facial features and sexual color dimorphism, generally manifested as dimorphism of skin luminance, where men tend to…
AI-generated faces show lower morphological diversity than real faces do
Some recent studies suggest that artificial intelligence can create realistic human faces subjectively unrecognizable from faces of real people. We have compared static facial photographs of 197 real men with a sample of 200 male faces generated by artificial intelligence to test whether they converge in basic morphological characteristic such as shape variation and bilateral asymmetry. Both datasets depicted standardized faces of European men wi…

Sexual Dimorphism in Facial Contrast
Reasons of Singles for Being Single
The current research aimed to examine the reasons people are single, that is, not in an intimate relationship, across eight different countries—Brazil, China, Czech Republic, Greece, Hungary, India, Japan, and the UK. We asked a large cross-cultural sample of single participants ( N = 6,822) to rate 92 different possible reasons for being single. These reasons were classified into 12 factors, including one’s perceived inability to find the right …
Differential effects of resource scarcity and pathogen prevalence on heterosexual women's facial masculinity preferences
The present research focused on how environmental harshness may affect heterosexual women's preferences of potential male mates’ facial characteristics, namely masculinity–femininity. The evidence on this issue is mixed and mostly from Western samples. We aimed to provide causal evidence using a sample of Turkish women and Turkish male faces. A video-based manipulation was developed to heighten environmental harshness perceptions. In the main exp…

Nomadic pastoralists and sedentary farmers of the Sahel/Savannah Belt of Africa in the light of geometric morphometrics based on facial portraits
OBJECTIVES: The Sahel/Savannah belt is a region where two sympatric human subsistence strategies-nomadic pastoralism and sedentary farming-have been coexisting for millennia. While earlier studies focused on estimating population differentiation and genetic structure of this ecologically remarkable region's inhabitants, less effort has been expended on understanding the morphological variation among local populations. MATERIALS AND METHODS: To fi…
A cross‐cultural study of sex‐typicality and averageness
OBJECTIVES: Facial averageness and sexual dimorphism are extensively studied attractiveness markers, which are viewed as possible indicators of biological quality. Both are complex morphological traits, and both can be easily assessed from frontal and lateral projection of a human face. Interestingly, examination of mutual relations between the frontal and lateral dimensions of these markers has so far received little attention in published resea…

Does age difference really matter? Facial markers of biological quality and age difference between husband and wife
Further evidence for links between facial width‐to‐height ratio and fighting success
Recent research has reported an association between facial width-to-height ratio (fWHR) and both fighting performance and judgments of formidability in a sample of mixed martial arts (MMA) combatants. The results provide evidence of fWHR being associated with sporting performance and aggression in men. However, it has been argued that the effect of fWHR might be a by-product of associations between body size and behavioral measures. Here we teste…
Shape Differences Between the Faces of Homosexual and Heterosexual Men
Re-semblance and re-evolution
The independent emergence of similar features in phylogenetically nonallied groups of organisms has usually been explained as the result of similar selection pressures particular to specific environments. This explanation has been more or less helpful in elucidating convergent resemblances among organisms since the times of Darwin. Nevertheless, intensive research has brought new knowledge on the emergence of structural similarity among organisms…
Mutual understanding and misunderstanding in biological systems mediated by self-representational meaning of organisms
Modern biology gives many casuistic descriptions of mutual informational interconnections between organisms. Semiotic and hermeneutic processes in biosphere require a set of “sentient” community of players who optimize their living strategies to be able to stay in game. Perceptible surfaces of the animals, semantic organs, represent a special communicative interface that serves as an organ of self-representation of organic inwardness. This means …
Monsters we met, monsters we made
Creatures living under the rule of domestication form a communicative union based on shared morphological, behavioural, cognitive, and immunological resemblances. Domestic animals live under particular conditions that substantially differ from the original (natural) settings of their wild relatives. Here we focus on the fact that many parallel characters have appeared in various domestic forms that had been selected for different purposes. These …
