"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 ( = 678) reason about their moral judgments of GC and GN peers.

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).

Protracted neuronal maturation in a long-lived, highly social rodent.

Naked mole-rats are a long-lived rodent species (current lifespan >37 years) and an increasingly popular biomedical model. Naked mole-rats exhibit neuroplasticity across their long lifespan. Previous studies have begun to investigate their neurogenic patterns.

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.

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.

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.

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.

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.

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.

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.

Cognitive processing of sexual cues in asexual individuals and heterosexual women with desire/arousal difficulties.

Asexuality is defined as a unique sexual orientation characterized by a lack of sexual attraction to others. This has been challenged, with some experts positing that it is better explained as a sexual dysfunction. Sexual Interest/Arousal Disorder (SIAD) is characterized by absent/reduced sexual interest/arousal paired with personal distress, with two subtypes: acquired and lifelong.

Gender-related variables for health research.

Background: In this paper, we argue for Gender as a Sociocultural Variable (GASV) as a complement to Sex as a Biological Variable (SABV). Sex (biology) and gender (sociocultural behaviors and attitudes) interact to influence health and disease processes across the lifespan-which is currently playing out in the COVID-19 pandemic. This study develops a gender assessment tool-the Stanford Gender-Related Variables for Health Research-for use in clinical and population research, including large-scale health surveys involving diverse Western populations.

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.

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.

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).

Facial Attractiveness of Sisters of Thai Gay Men and .

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.

Sex difference or hormonal difference in mental rotation? The influence of ovarian milieu.

Sex differences in visuospatial cognition have long been reported, with men being advantaged on the Mental Rotations Test (MRT). The data, however, are variable, and sensitive to design parameters. When men and women are compared directly, with women in different hormonal milieus combined, there seem to be sex differences.

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.

Gender Variance and the Autism Spectrum: An Examination of Children Ages 6-12 Years.

Gender variance (GV) and autism spectrum disorder (ASD) frequently co-occur in clinical populations. We investigated GV in association with ASD characteristics in nonclinical children and in children with developmental/mental health diagnoses. In 6-12-year-olds (N = 2445; 51% birth-assigned boys), the Gender Identity Questionnaire for Children measured GV and the Children's Social Behavior Questionnaire measured six subdomains of ASD characteristics.

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.

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.

Settling for less out of fear of being single.

The present research demonstrates that fear of being single predicts settling for less in romantic relationships, even accounting for constructs typically examined in relationship research such as anxious attachment. Study 1 explored the content of people's thoughts about being single. Studies 2A and 2B involved the development and validation of the Fear of Being Single Scale.
