"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 and girls, we asked children whether each target peer's behavior was right or wrong and why they thought so. We coded children's reasoning using a new coding scheme developed via inductive content analysis. Overall, children's most commonly used reasoning styles were global standard, personal choice, gender stereotypes, "don't know," and others' welfare. Children used more gender stereotype-related reasoning when they were older and from Hong Kong, appraising the GN boy, or when they perceived the target's behavior as wrong. In contrast, children reasoned based on personal choice more when they were from Canada or when they perceived the target's behavior as right. These findings inform how age-, gender-, and culture-related factors are associated with children's reasoning about the acceptability or appropriateness of varying kinds of childhood gendered behavior. They provide insights regarding children's appraisals of different gender expressions by illuminating not only how they view GC and GN peers but also, from their own perspectives, why they do so. These insights have implications for strategies aimed at decreasing gender-related biases and increasing children's acceptance of gender diversity.

Not Who You Are, But Who You Are With: Re-examining Women's Less Satisfying Sexual Debuts.

Gender differences in appraisals of first intercourse are among the largest in sexuality research, with women indicating less satisfying "sexual debuts" than men. Dispositional or "actor-level" explanations for this gender gap are pervasive, yet research has largely examined heterosexual debuts in which actor gender and partner gender are confounded. We assessed whether women's less satisfying sexual debuts are better explained by actor gender or partner gender, comparing experiences of women who debuted with men (WDM) with those of men and women who debuted with women (MDW, WDW). Retrospective accounts of sexual debut were collected from 3033 adults. At first intercourse, we found that WDW had equal physical and emotional satisfaction to MDW, and more satisfaction than WDM, suggesting satisfaction gaps owing to partner gender, not actor gender. This pattern did not extend to a comparison event (first masturbation), where WDW and WDM had similar satisfaction, but less satisfaction than MDW, suggesting an actor gender gap. To identify sources of satisfaction gaps, we probed for corresponding differences in the circumstances of sexual debut. Sexual circumstances were more strongly implicated than nonsexual ones, with relative deprivation of glans stimulation explaining relative dissatisfaction at first intercourse, but not first masturbation, and orgasm explaining it at both. Findings challenge the view that the satisfaction gap at first intercourse reflects an inherent difference between genders. Indeed, they demonstrate similarities when partner gender does not differ and suggest strategies for ensuring equal sexual satisfaction-and equal sexual rights realization-at (hetero) sexual debut.

Carving the Biodevelopment of Same-Sex Sexual Orientation at Its Joints.

Sexual orientation is a core aspect of human experience and understanding its development is fundamental to psychology as a scientific discipline. Biological perspectives have played an important role in uncovering the processes that contribute to sexual orientation development. Research in this field has relied on a variety of populations, including community, clinical, and cross-cultural samples, and has commonly focused on female gynephilia (i.e., female sexual attraction to adult females) and male androphilia (i.e., male sexual attraction to adult males). Genetic, hormonal, and immunological processes all appear to influence sexual orientation. Consistent with biological perspectives, there are sexual orientation differences in brain development and evidence indicates that similar biological influences apply across cultures. An outstanding question in the field is whether the hypothesized biological influences are all part of the same process or represent different developmental pathways leading to same-sex sexual orientation. Some studies indicate that same-sex sexually oriented people can be divided into subgroups who likely experienced different biological influences. Consideration of gender expression in addition to sexual orientation might help delineate such subgroups. Thus, future research on the possible existence of such subgroups could prove to be valuable for uncovering the biological development of sexual orientation. Recommendations for such future research are discussed.

The Risks and Benefits of Being "Early to Bed": Toward a Broader Understanding of Age at Sexual Debut and Sexual Health in Adulthood.

BACKGROUND: A younger age at sexual intercourse has frequently been linked to adverse sexual health outcomes. Yet, little is known about its associations with healthy sexual function, and less still about the timing of pre-coital sexual debuts and adult sexual health. AIM: We examined associations between an earlier sexual debut and subsequent sexual health, using broad operationalizations of each that capture pre-coital experiences and positive outcomes. Connections to sexual health risk and healthy sexual function were assessed through the lens of the dual-control model of sexual response. METHODS: Data on age at first sexual intercourse, first sexual contact, first sexual stimulation, and first orgasm, as well as sexual health risk and healthy sexual function were gathered from 3,139 adults. OUTCOMES: Adverse sexual events (reproductive illness, infection, or injury affecting sexual activity; pregnancy termination and/or loss; non-volitional sex) and current sexual difficulties (Female [FSFI] and/or Male Sexual Function Index [MSFI] scores; Sexual Excitation and/or Sexual Inhibition Inventory for Women and Men [SESII-W/M] scores). RESULTS: When defined narrowly as first sexual intercourse, earlier sexual debut was associated with adverse sexual events, including non-volitional sex, pregnancy termination and/or loss, and reproductive illness, infection, or injury affecting sexual activity. However, it was also related to healthier sexual function, including less pain during vaginal penetration, better orgasmic functioning, and lower sexual inhibition. When sexual debut was broadened to include pre-coital experiences, earlier sexual contact, like earlier sexual intercourse, was associated with non-volitional sex. However, earlier sexual stimulation and orgasm were unrelated to adverse outcomes. Rather, these related to fewer sexual desire difficulties, and greater sexual excitation. Exploratory mediation analyses revealed later sexual intercourse and orgasm were connected to sexual difficulties through higher sexual inhibition and lower sexual excitation, respectively. CLINICAL IMPLICATIONS: When sexual functioning is impaired, delay of both coital and noncoital debuts may warrant assessment, and sexual excitation and inhibition may be targets for intervention. To facilitate healthy sexual development of young people, non-coital debuts with and without a partner may warrant inclusion in risk management and health promotion strategies, respectively. STRENGTHS & LIMITATIONS: Although this research operationalized sexual debut and sexual health broadly, and examined associations between them, it is limited by its cross-sectional retrospective design and non-clinical convenience sample. CONCLUSION: From a risk-based perspective, earlier sexual intercourse is adversely related to sexual health. Yet, it is also associated with healthy sexual function. Indeed, earlier sexual initiation may confer more benefits than risks when sexual debuts beyond intercourse are considered. Peragine DE, Skorska MN, Maxwell JA, et al.

Explicit and Implicit Gender-Related Stereotyping in Transgender, Gender Expansive, and Cisgender Adults.

Little is known about gender-related stereotyping among transgender and gender expansive adults. Using the Ambivalent Sexism Inventory (AIS; Glick & Fiske, 1996), we examined explicit gender attitudes in 3298 cisgender, transgender, and gender expansive respondents designated female at birth (FAB; n = 1976 cisgender, n = 108 transgender, n = 188 gender expansive) and male at birth (MAB; n = 922 cisgender, n = 52 transgender, n = 52 gender expansive). In order to learn more about implicit gender-related stereotyping, a subset of 822 participants (FAB; n = 445 cisgender, n = 32 transgender, n = 51 gender expansive. MAB; n = 254 cisgender, n = 21 transgender, n = 19 gender expansive) completed the gender-leadership Implicit Association Test (IAT; Dasgupta & Asgari, 2004). Cisgender men scored significantly higher than all other groups on hostile sexism, but patterns of endorsement for benevolent sexism and implicit attitudes were more nuanced, with cisgender women and gender expansive FAB often scoring significantly below other groups. We observed that transgender men and transgender women, along with cisgender men and gender expansive MAB, moderately endorsed essentialist views regarding differences between men and women (i.e., complementary gender differentiation). These data reveal novel patterns of gender-related stereotyping, with some corresponding to sex designated at birth and others corresponding to current gender identification. Together, these findings suggest that one's experienced gender, designated sex at birth, and the intersection between them may relate to gender stereotyping, underscoring the importance of including transgender and gender expansive individuals in this research.

A new angle on mental rotation ability in transgender men: Modulation by ovarian milieu.

Organizational/activational theory posits that transgender individuals should perform in the direction of their gender, not their sex, on cognitive tasks that show sex differences-the largest of which are observed on visuospatial tasks. Yet, tests of this hypothesis have been mixed for transgender men (TM). One possible reason is that performance shifts associated with the hormonal milieu at testing have not been fully considered in TM. Although "activating" influences, like gender-affirming hormone therapy (GAHT), are well-characterized in this population, endogenous ones, like ovarian cycling, have gone unaddressed. To provide a more complete picture of hormonal activation, we explored an influence of ovarian milieu on visuospatial performance of TM, and its potential contributions toward effects of sex and GAHT. We administered two male-favoring mental rotation tests (MRTs), and a sex-neutral control task to 22 TM naïve to GAHT (TM-), 29 TM receiving GAHT (TM+), and cisgender men (CM; n = 24) and women (CW; n = 43), testing cycling men (TM-) and women (CW) in either early follicular phase (Follicular) or midluteal phase (Luteal). On MRTs, performance of TM- varied across the menstrual cycle, and matched that of menstrual phase-matched CW. Additionally, cycling individuals in Follicular performed as strongly as TM+ and CM, all of whom performed above individuals in Luteal. Effects did not extend to a verbal control task, on which TM+ performed below others. Rather than conforming to static categories that suggest sex- or gender-typical organization of cognitive circuits, our findings support dynamic shifts in visuospatial ability of TM, and illustrate the need to consider activating effects of hormones beyond GAHT.

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 whether women's lower sexual desire is explained by their gender or by gendered experience of enjoyment at sexual debut. Emerging adults (N = 838) provided retrospective accounts of physical (orgasm) and affective (satisfaction) enjoyment at (hetero)sexual debut. We replicated gender differences across behavioral, general, and multidimensional measures of trait sexual desire; however, they were contingent on experience and measurement method. When its cognitive multidimensional properties were appreciated, women's sexual desire varied with experience of orgasm at sexual debut and diverged from men's only when orgasm did not occur. Such effects were not observed for satisfaction, nor for men. Nor did effects of a control event - masturbatory debut - extend beyond solitary sexual desire. Findings underscore the importance of orgasm equality, and suggest its absence at sexual debut may play an unacknowledged role in differentiating sexual desire.

Mental rotation task performance in relation to sexual and gender diversity in Thailand.

Neurohormonal theory argues that organizational effects of hormone exposure influence sexual orientation and gender identity, as well as sex differences in visuospatial cognition. This study examined mental rotation task (MRT) performance in a diverse Thai sample (N = 980). Thai culture has several third genders: individuals assigned male at birth (AMAB) who are feminine and attracted to cis men (i.e., sao praphet song); individuals assigned female at birth (AFAB) who are masculine and attracted to feminine individuals (i.e., toms); AFAB individuals who are feminine and attracted to toms (i.e., dees); and sexual orientation categories similar to Western culture (e.g., gay, lesbian, bi). On the MRT, straight cis men outperformed straight cis women. Results were consistent with organizational effects among AMAB individuals, with straight cis men outperforming gay cis men and sao praphet song. Among AFAB individuals, however, only bi and lesbian cis women outperformed dees. Overall, support for neurohormonal theory was limited among AFAB individuals, but MRT performance among AMAB individuals was consistent with organizational effects. This study informs our understanding of visuospatial sex/gender differences and the applicability of neurohormonal theory across cultures.

An anthropometric study of sexual orientation and gender identity in Thailand.

The biodevelopment of psychological sex differentiation is putatively reflected in several anthropometrics. We examined eight anthropometrics in 1404 Thai participants varying in sex, sexual orientation, and gender identity/expression: heterosexual men and women, gay men, lesbian women, bisexual women, sao praphet song (transgender birth-assigned males), toms (transgender birth-assigned females), and dees (birth-assigned females attracted to toms). Exploratory factor analyses indicated the biomarkers should be analyzed independently. Using regressions, in birth-assigned males, less male-typical second-to-fourth digit ratios in the left hand were associated with sexual orientation towards men regardless of gender identity/expression, whereas shorter height and long-bone growth in the arms and legs were more evident among sao praphet song-who are both sexually oriented towards men and markedly feminine. In birth-assigned females, there were no clear sexual orientation effects, but there were possible gender-related effects. Groups of individuals who tend to be more masculine (i.e., toms, lesbians) showed more male-typical patterns on weight and leg length than some groups of individuals who tend to be less masculine (i.e., heterosexual women, dees). Thus, it appears the various anthropometrics inform separate biodevelopmental processes that differentially relate to sexual orientation and gender identity/expression depending on the measure in question as well as birth-assigned sex.

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 - identifying as gay men or as a third gender known as sao praphet song. Thus, a field experiment was conducted in which 208 heterosexual men rated the facial attractiveness of 25 sisters of Thai gay men or sao praphet song and 25 comparison women with no known same-sex attracted relatives. Contrary to the prediction, the comparison group was rated as more attractive than the sisters, casting doubt on hypotheses that posit greater attractiveness of female relatives of male androphiles as a proximate mechanism facilitating the evolutionary maintenance of genes influencing male androphilia. Also, men from rural areas rated the women, regardless of group, as more attractive than men from urban areas, consistent with some prior studies showing rural-urban differences in perceptions of attractiveness.

Children's intergroup gender bias and self-perceived same- and other-gender similarity.

Children display intergroup bias in relation to gender. The present study examined whether children's self-perceived same- and other-gender similarity were related to their same- and other-gender positivity and negativity, respectively. Children aged 6-10 years (N = 149) were interviewed about their self-perceived similarity to girls and to boys and about the extent to which they thought positive and negative characteristics applied to boys and to girls. Among girls, greater self-perceived other-gender similarity was associated with more negativity towards the same gender. Similar to previous research, intergroup gender bias was more pronounced among girls, and children rated themselves as having more same- than other-gender similarity, with this pattern being more pronounced in boys. Thus, this study provides evidence suggesting that other-gender similarity is related to girls' negative attributions towards girls. It also replicates previous findings regarding gender differences in children's intergroup gender bias and gender similarity, respectively.

Examining the Relation Between Gender Nonconformity and Psychological Well-Being in Children: The Roles of Peers and Parents.

No study to date has simultaneously tested how poor peer relations, generic risk factors, and parental attitudes impact the behavioral and emotional challenges of children who vary in their gender expression. In a community sample, the present study investigated various hypothesized psychosocial and generic risk factors regarding the association between childhood gender nonconformity (GNC) and psychological well-being. Canadian parents/guardians reported on their children aged 6-12 years (N = 1719, 48.8% assigned male at birth) regarding their child's GNC, measured by the Gender Identity Questionnaire for Children; behavioral and emotional challenges, measured by the Child Behavior Checklist (CBCL); and peer relations, measured by the CBCL and Strength and Difficulties Questionnaire. Parent/guardian gender-stereotypical attitudes toward child-rearing were assessed using an adapted version of the Child-Rearing Sex Role Attitude Scale, and attachment between the parent/guardian and child was measured with an adapted version of the Child-Rearing Practices Report. Based on regression analyses, GNC was related to elevated behavioral and emotional challenges, and this association was stronger for those who experienced poor peer relations as well as for those whose parents/guardians endorsed gender-stereotyped attitudes and were less willing to serve as a secure base for the child. Recommendations are provided for ways in which social environments can be altered to improve psychological well-being among gender-nonconforming children.

Children's bias in appraisals of gender-variant peers.

Past research suggests that children have biased negative appraisals of gender-variant (GV) peers (i.e., peers who display behaviors/interests that do not align with gender stereotypes). In the current study, Canadian cisgender 4- and 5-year-olds and 8- and 9-year-olds (N = 183; 48.6% girls), who were ethnically diverse (36% White European heritage) and from mostly middle- to upper-income families, viewed vignettes depicting boys and girls as either gender-conforming (GC) or GV. Multiple measures gauged children's appraisals in various domains (i.e., friendship/social preference, popularity, happiness, imitation, and moral judgment). Children's bias against GV peers was modest. Children preferred peers who presented as the same gender and/or with same-gender-typed behaviors/interests. Compared with GC peers, GV peers were rated as less happy, and older children rated a GV boy as less popular. When juxtaposed with a previous study of Hong Kong children that used the same study design, there were several parallels in the patterns observed, but Canadian children had a weaker and less consistent pattern of bias against GV peers than children from Hong Kong. In addition, children from these two cultures showed discrepant patterns for certain aspects of appraisals (e.g., happiness, moral judgment). Overall, these findings inform age-, gender-, and cultural-related influences on children's appraisals of GV peers.

Separation anxiety and gender variance in a community sample of children.

In clinical child and retrospective adult samples, childhood gender variance (GV; i.e., cross-gender behaviour) has been associated with separation anxiety (SA; i.e., distress related to separation from attachment figures) in males. This study examined GV and SA in a nonclinical sample of 892 boys and 933 girls aged 6-12 years via parent-reports. Parental factors (i.e., parenting style, parent-child relationship, willingness to serve as an attachment figure, attitudes towards gender stereotypes in children) were examined as potential moderators. GV predicted SA in boys, even when statistically controlling for general psychopathology and demographic variables. Authoritative parenting, closeness in the parent-child relationship, willingness to serve as an attachment figure, and liberal attitudes towards gender stereotypes in children moderated the association between GV and SA in both boys and girls. Thus, SA may be a unique internalizing problem related to GV in boys in nonclinical samples and influenced by a variety of parental factors.

RFamide-related peptide-3 (RFRP-3) suppresses sexual maturation in a eusocial mammal.

Neuroendocrine mechanisms underlying social inhibition of puberty are not well understood. Here, we use a model exhibiting the most profound case of pubertal suppression among mammals to explore a role for RFamide-related peptide-3 [RFRP-3; mammalian ortholog to gonadotropin-inhibitory hormone (GnIH)] in neuroendocrine control of reproductive development. Naked mole rats (NMRs) live in sizable colonies where breeding is monopolized by two to four dominant animals, and no other members exhibit signs of puberty throughout their lives unless they are removed from the colony. Because of its inhibitory action on the reproductive axis in other vertebrates, we investigated the role of RFRP-3 in social reproductive suppression in NMRs. We report that RFRP-3 immunofluorescence expression patterns and RFRP-3/GnRH cross-talk are largely conserved in the NMR brain, with the exception of the unique presence of RFRP-3 cell bodies in the arcuate nucleus (Arc). Immunofluorescence comparisons revealed that central expression of RFRP-3 is altered by reproductive status, with RFRP-3 immunoreactivity enhanced in the paraventricular nucleus, dorsomedial nucleus, and Arc of reproductively quiescent NMRs. We further observed that exogenous RFRP-3 suppresses gonadal steroidogenesis and mating behavior in NMRs given the opportunity to undergo puberty. Together, our findings establish a role for RFRP-3 in preserving reproductive immaturity, and challenge the view that stimulatory peptides are the ultimate gatekeepers of puberty.

A game of thrones: neural plasticity in mammalian social hierarchies.

Social status is a key regulator of health and reproduction in mammals, including humans. Despite this, relatively little is known about how social status influences the mammalian brain. Furthermore, the extent to which status is an independent construct, i.e., not simply acting as a psychosocial stressor, is yet to be determined. Research to date reveals several promising mechanisms and/or systems associated with social status, including monoamine systems, hypothalamic neuroendocrine axes, and the hippocampus, though whether these differences are the cause or effect of status is often unclear. We review these candidates and propose how best to approach this research question in the future.
