Modernization, collectivism, and gender equality predict love experiences in 45 countries.

Recent cross-cultural and neuro-hormonal investigations have suggested that love is a near universal phenomenon that has a biological background. Therefore, the remaining important question is not whether love exists worldwide but which cultural, social, or environmental factors influence experiences and expressions of love. In the present study, we explored whether countries' modernization indexes are related to love experiences measured by three subscales (passion, intimacy, commitment) of the Triangular Love Scale.

Sex differences in human mate preferences vary across sex ratios.

A wide range of literature connects sex ratio and mating behaviours in non-human animals. However, research examining sex ratio and human mating is limited in scope. Prior work has examined the relationship between sex ratio and desire for short-term, uncommitted mating as well as outcomes such as marriage and divorce rates.

Affective Interpersonal Touch in Close Relationships: A Cross-Cultural Perspective.

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 for 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 the week preceding the study. We then examined a range of hypothesized individual-level factors (sex, age, parasitic history, conservatism, religiosity, and preferred interpersonal distance) and cultural-level factors (regional temperature, parasite stress, regional conservatism, collectivism, and religiosity) in predicting these affective-touching behaviors.

Evolution of Gender Stereotypes in Spain: From 1985 to 2018.

Background: Gender stereotypes are the images, beliefs, or expectations that people have about men and women. Have these stereotypes changed in Spain in recent decades?

Method: In this study we present data on gender stereotypes in Spain in two different time periods (1985, N = 1060; and 2018, N = 802).

Results: Results indicate that of the four components of the stereotypes analyzed (traits, role behaviors, occupations, and physical characteristics), the stereotypes in three of them have changed.

Universality of the Triangular Theory of Love: Adaptation and Psychometric Properties of the Triangular Love Scale in 25 Countries.

The Triangular Theory of Love (measured with Sternberg's Triangular Love Scale - STLS) is a prominent theoretical concept in empirical research on love. To expand the culturally homogeneous body of previous psychometric research regarding the STLS, we conducted a large-scale cross-cultural study with the use of this scale. In total, we examined more than 11,000 respondents, but as a result of applied exclusion criteria, the final analyses were based on a sample of 7332 participants from 25 countries (from all inhabited continents).

Sex Differences in Mate Preferences Across 45 Countries: A Large-Scale Replication.

Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives-an evolutionary psychological perspective and a biosocial role perspective-offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions.

Contrasting Computational Models of Mate Preference Integration Across 45 Countries.

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 ideal preferences to guide the choice of actual romantic partners, human mating psychology must possess a means to integrate information across these many preference dimensions into summaries of the overall mate value of their potential mates.

Focusing on one's own appearance leads to body shame in women but not men: The mediating role of body surveillance and appearance-contingent self-worth.

Previous research has shown that some appearance-focused situations lead to increased self-objectification, especially among women. The present research explored, with an experimental design, whether the simple fact of thinking about one's own physical appearance increases body shame through body surveillance and appearance-contingent self-worth in men and women. Our main prediction was that focusing on one's own appearance would increase both women's body surveillance and appearance-contingent self-worth, and that both variables in turn would increase women's body shame.

Stranger Harassment ("Piropo") and Women's Self-Objectification: The Role of Anger, Happiness, and Empowerment.

According to objectification theory, women's habitual exposure to sexually objectifying situations can lead them to internalize a third-person perspective of themselves in physical terms, leading women to adopt an observer's viewpoint of themselves as a body or collection of body parts that is valued principally for use or consumption by others (i.e., self-objectification).
