Kin-Directed Altruism and Male Androphilia in Thailand: Investigating the Roles of Femininity and Neuroticism
Sexual and Gender Diversity in Thailand: Associations with Recalled Childhood Sex-Typed Behavior and Adulthood Occupational Preferences
Same-sex attracted individuals report greater levels of sex-atypical childhood behaviors and adulthood occupational preferences when compared with their heterosexual counterparts. While these sexual orientation differences are well established, the extent to which gender-role presentation relates to such differences is unclear. The present study examined recalled childhood sex-(a)typical behaviors (CSAB) and adulthood occupational preferences in …
Children’s Facial Emotional Expressions to Gender-Nonconforming Hypothetical Peers
Gender diversity is correlated with dimensional neurodivergent traits but not categorical neurodevelopmental diagnoses in children
BACKGROUND: Gender clinic and single-item questionnaire-based data report increased co-occurrence of gender diversity and neurodevelopmental conditions. The nuances of these associations are under-studied. We used a transdiagnostic approach, combining categorical and dimensional characterization of neurodiversity, to further the understanding of its associations with gender diversity in identity and expression in children. METHODS: Data from 291 …
He did girls’ things!” Hong Kong and Canadian children’s reasoning about moral judgments of peers’ gendered behaviors
Children show less positivity toward gender-nonconforming (GN) than gender-conforming (GC) peers. Yet, little is known about children's reasoning about peers of varying gender expressions, including age-, gender-, and culture-related influences. We investigated how children aged 4- to 5- and 8- to 9-years-old in Hong Kong and Canada ( N = 678) reason about their moral judgments of GC and GN peers. After viewing vignettes describing GC and GN boys…
Observations on Gender Variance in Chinese Community Children Measured by the Gender Identity Questionnaire for Children

Gender variance and psychological well-being in Chinese community children
Childhood gender variance (GV) and its association with psychological well-being have garnered increasing interest recently but little is known about children from the community and non-Western samples. Therefore, we examined GV and its associations with psychological well-being in a Chinese community sample where study of childhood GV is extremely rare. Parents of 461 Chinese children aged 4–12 years (243 birthassigned males) provided informatio…
Children’s implicit gender–toy association development varies across cultures
Gender-stereotyped beliefs develop early in childhood and are thought to increase with age based on prior research that was primarily carried out in Western cultures. Little research, however, has examined cross-cultural (in)consistencies in the developmental trajectory of gender-stereotyped beliefs. The present study examined implicit gender-toy stereotypes among 4- to 9-year-olds ( N = 1,013; 49.70% girls) in Canada, China, and Thailand. Childr…

Recalled Childhood Separation Anxiety in Relation to Sex, Sexual Orientation, and Gender Identity in Thailand
Same-sex sexual attraction is an evolutionary paradox. It is influenced by genes but also associated with reduced reproduction. An altruistic disposition toward kin could increase relatives' reproduction, thus addressing this paradox. Developmentally, such a disposition may manifest as anxiety during separation from kin. This hypothesis has been supported among androphilic (i.e. sexually attracted to males) males, but few similar studies of gynep…

A Learning Experience? Enjoyment at Sexual Debut and the Gender Gap in Sexual Desire among Emerging Adults
Gender differences in experience of first intercourse are among the largest in sexuality research, with women recalling less pleasure and satisfaction than men. This "enjoyment gap" has not been considered in explanations of gender differences in sexual desire. Yet, reinforcement and incentive learning feature prominently in recent models of women's sexual desire, and nonhuman animal models demonstrate their impact at sexual debut. We examined wh…

Recalled Childhood Separation Anxiety Differs by Anal Sex Role among Gay Men
Male androphilia (i.e., male sexual attraction to adult males) is considered an evolutionary paradox because it is partially influenced by genes and associated with decreased reproduction. Traits associated with attachment to genetic relatives (i.e., kin) could prompt increased kin-directed altruism, thereby offsetting decreased reproduction by helping kin reproduce. These traits include childhood separation anxiety and adulthood neuroticism, whi…

Cultural Influences on Perceptions of Emotions Depicted in Emojis
Previous research suggests that people from different cultures weigh cues in the eyes versus mouth differently while interpreting emotions. In Western cultures, where overt emotional display is the norm, people weigh the mouth region more heavily when interpreting facial emotional expression in comparison with people from Eastern cultures. By contrast, in Eastern cultures, where subtle emotion display is the norm, people weigh the eyes region mor…
Children’s Appraisals of Gender Nonconformity: Developmental Pattern and Intervention
Gender-nonconforming (GN) children are often perceived less positively, which may harm their well-being. We examined the development of such perceptions and an intervention to modify them. Chinese children’s appraisals were assessed using multiple measures (verbal responses, sharing, and rank order task) after viewing vignettes of gender-conforming (GC) and GN hypothetical peers. In Study 1, children (N = 210; 4-, 5-, 8-, and 9-year-olds) were le…
Facial Attractiveness of Sisters of Thai Gay Men and Sao Praphet Song
Androphilia refers to sexual attraction toward adult males. Androphilic males' female genetic relatives might offset the fitness cost of androphilia by having elevated numbers of offspring. Increased attractiveness relative to other women may enable these females to marry up the social hierarchy, providing greater access to resources to support more offspring. In Thailand, there is a marked status hierarchy and male androphiles are highly visible…

Familial Patterning and Prevalence of Male Androphilia in Samoa
Previous research established that male androphilia (i.e., sexual arousal and attraction to adult males) clusters in families. Some studies find that male androphilia clusters in both the paternal and maternal lines, while others find that it clusters only in the latter. Most of the research investigating the familial nature of male androphilia has taken place in Western cultural contexts that are problematic for such research because they are ch…

Sexual Orientation in Men and Avuncularity in Japan: Implications for the Kin Selection Hypothesis
Male Sexual Orientation and Avuncularity in Canada: Implications for the Kin Selection Hypothesis
Androphilia refers to sexual attraction and arousal to adult males, whereas gynephilia refers to sexual attraction and arousal to adult females. The Kin Selection Hypothesis (KSH) posits that genes for male androphilia can persist if androphilic males offset the fitness costs of not reproducing directly by enhancing indirect fitness. In theory, by directing altruistic behavior toward kin, androphilic males can increase the reproduction of kin, th…

Do Children With Gender Dysphoria Have Intense/Obsessional Interests
This study examined whether children clinically referred for gender dysphoria (GD) show increased symptoms of autism spectrum disorder (ASD). Circumscribed preoccupations or intense interests were considered as overlapping symptoms expressed in GD and ASD. In gender-referred children (n = 534; 82.2% male) and their siblings (n = 419; 57.5% male), we examined Items 9 and 66 on the Child Behavior Checklist, which measure obsessions and compulsions,…
Direct Reproduction and Sexual Orientation and Gender Diversity in Thailand
Does Geographic Proximity Influence The Expression of Avuncular Tendencies in Canadian Androphilic Males
Androphilia refers to sexual attraction and arousal to adult males, whereas gynephilia refers to sexual attraction and arousal to adult females. The Kin Selection Hypothesis posits that male androphilia may persevere over evolutionary time if the fitness costs of not reproducing directly are offset by increasing one’s inclusive fitness. Theoretically, this could be accomplished by allocating altruism toward close kin, thereby increasing the abili…
Birth Order and Avuncular Tendencies in Samoan Men and Fa’afafine
(Trans)Gender Role Expectations and Child Care in Samoa
Samoan transgendered males are known as fa'afafine. Although Samoan women are characterized as the primary child care providers, fa'afafine report elevated willingness to invest in nieces and nephews compared to men and women. We hypothesized that Samoans hold unique transgender role expectations such that fa'afafine are expected to invest more toward nieces and nephews compared to others. Participants (N = 214) included Samoan men (30.23 years ±…

Separation Anxiety in Feminine Boys: Pathological or Prosocial
Previous research has found that boys who exhibit Gender Identity Disorder in Children (GIDC) also commonly exhibit elevated traits of childhood separation anxiety. Here, we review recent cross-cultural, nonclinical research that suggests elevated childhood separation anxiety is simply a component of the more general pattern of femininity exhibited by pre-androphilic males (i.e., biological males who are sexually attracted to adult males in adult…

Relationship status and elevated avuncularity in Samoan fa’afafine
“Androphilia” and “gynephilia” refer to sexual attraction to adult males and females, respectively. Samoan androphilic males are known as fa’afafine . Previously, fa’afafine reported greater avuncular tendencies compared to those of men as well as the materteral (i.e., aunt‐like) tendencies of women. Here, the Samoan male sexual orientation difference in avuncular tendencies was replicated. Furthermore, we hypothesized fa’afafine might form and i…
No Evidence for Treating Friends’ Children Like Kin in Canadian Androphilic Men
Given that same-sex sexual orientation is associated with lower reproductive success, how have genes associated with male androphilia (i.e., male sexual attraction/arousal to adult men) persisted over evolutionary time? The Kin Selection Hypothesis proposes that by directing valuable resources toward kin, androphilic men may enhance their indirect fitness and thereby offset the fitness costs of not reproducing directly. Support for this hypothesi…
