Abstract Humans express a wide array of ideal mate preferences. Around the world, people desire romantic partners who are intelligent, healthy, kind, physically attractive, wealthy, and more. In order for these preferences to guide choice actual partners, human mating psychology must possess means integrate information across many preference dimensions into summaries overall value their potential mates. Here we explore computational design this integration process using large sample n =...
Considerable research has examined human mate preferences across cultures, finding universal sex differences in for attractiveness and resources as well sources of systematic cultural variation. Two competing perspectives-an evolutionary psychological perspective a biosocial role perspective-offer alternative explanations these findings. However, the original data on which each relies are decades old, literature is fraught with conflicting methods, analyses, results, conclusions. Using new...
Interpersonal touch behavior differs across cultures, yet no study to date has systematically tested for cultural variation in affective touch, nor examined the factors that might account this variability. Here, over 14,000 individuals from 45 countries were asked whether they embraced, stroked, kissed, or hugged their partner, friends, and youngest child during week preceding study. We then a range of hypothesized individual-level (sex, age, parasitic history, conservatism, religiosity,...
Abstract Recent cross-cultural and neuro-hormonal investigations have suggested that love is a near universal phenomenon has biological background. Therefore, the remaining important question not whether exists worldwide but which cultural, social, or environmental factors influence experiences expressions of love. In present study, we explored countries’ modernization indexes are related to measured by three subscales (passion, intimacy, commitment) Triangular Love Scale. Analyzing data...
The Triangular Theory of Love (measured with Sternberg's Scale – STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body previous psychometric regarding STLS, we conducted large-scale cross-cultural study use this scale. In total, examined more than 11,000 respondents, but as result applied exclusion criteria, final analyses were based sample 7332 participants from 25 countries (from all inhabited continents). We tested configural...
Prior and ongoing COVID-19 pandemic restrictions have resulted in substantial changes to everyday life. The measures of its control affect mental health negatively. Self-reported data from 15,375 participants 23 countries were collected May August 2020 during the early phases pandemic. Two questionnaires measuring anxiety level used this study—the Generalized Anxiety Disorder Scale (GAD-7), State Inventory (SAI). associations between a set social indicators on (e.g., sex, age, country, live...
A wide range of literature connects sex ratio and mating behaviours in non-human animals. However, research examining human is limited scope. Prior work has examined the relationship between desire for short-term, uncommitted as well outcomes such marriage divorce rates. Less empirical attention been directed towards mate preferences, despite importance preferences literature. To address this gap, we ratio's to variation attractiveness, resources, kindness, intelligence health a long-term...

The COVID-19 pandemic has spread throughout the world, and concerns about psychological, social, economic consequences are growing rapidly. Individuals’ empathy-based reactions towards others may be an important resilience factor in face of COVID-19. Self-report data from 15,375 participants across 23 countries were collected May to August 2020 during early phases pandemic. In particular, this study examined different facets empathy—Perspective-Taking, Empathic Concern, Personal Distress,...
Background: Body height is a versatile bio-indicator in that it reflects the quality of physical development. Fluctuating asymmetry, on other hand, refers to small random deviations from perfect symmetry bilaterally paired structures and believed reflect ability an organism cope with genetic environmental stresses during its development.Aim: This study sought investigate relationship between body fluctuating asymmetry young adult males who display different height-development...
Digit ratio (2d/4d) in humans is commonly used as a proxy for the exposure to oestrogens and androgens prenatal life. Masculinisation/feminisation adults may be also related digit therefore oestrogen/androgen It has been shown, instance, that Waist-to-Hip (WHR) amount distribution of body fat are women. A species-specific, sexually dimorphic morphological trait pair permanent breasts develop during puberty, under influence oestrogens. Here we test if (in relation androgens), measured by...
Abstract Objective Random deviation from perfect symmetry of organisms is defined as fluctuating asymmetry. Fluctuating asymmetry widely considered to be a marker developmental instability, noise and phenotypic quality at the population level. In this study, we investigated hypothesized relationship between 2D:4D digit ratios proxy measure prenatal sex hormones instability levels in young adult humans. Materials Methods seven bilateral traits were measured for asymmetry, well second fourth...
Abstract Objectives The aim of this study was to investigate the effects parental consanguinity on 2D:4D digit ratio newborn infants, whose parents were first cousins. Methods included healthy and full‐term delivered in a hospital, at gestational ages from 37 41 weeks. A total 225 newborns their study. Of these newborns; 100 inbred 125 outbred infants. We used Vernier caliper measure length second fourth digits (accuracy: 0.01 mm). Results Controlling for education number pregnancies, male...
Some research in the field of anthropology provides some evidence that higher hand grip strength and a symmetrical body are reliable indicators health fitness. In this study, we consider relationship between these two healthy young individuals. 185 university students (87 males 97 females) were examined. addition to weight height students, eight bilateral traits measured with an accuracy 0.01 mm evaluate their bodily symmetry, was determined dynamometer by applying Southampton protocol. The...
Handgrip strength is a quick way to assess overall muscle strength. Low handgrip an indicator of poor health. While related with mortality and morbidity, for some parameters, even stronger predictor health than chronological age alone. highly sexually dimorphic has high heritability. It thought that this outcome sexual selection intrasexual competition in our evolutionary history. Some anthropological studies confirm view, it claimed there are relationships between grip aggression, athletic...
Previous studies have found a negative relationship between creativity and conservatism. However, as these were mostly conducted on samples of homogeneous nationality, the generalizability effect across different cultures is unknown. We addressed this gap by conducting study in 28 countries. Based notion that attitudes can be shaped both environmental ecological factors, we hypothesized parasite stress also affect thus, its potential effects should controlled for. The results multilevel...
ABSTRACT Objective Human sexual dimorphism in physical strength manifests itself men having a greater muscle mass than women, reflecting ancestral roles competition, protection, and provisioning. Prenatal testosterone exposure, approximated via the second‐to‐fourth digit ratio (2D:4D), is linked to increased muscular both sexes, indicating developmental influence. Previous research has shown that 2D:4D have facial shape correlates, especially men, but most studies focused on Western...
