Between a boy and a girl: Measuring gender identity on a continuum

Parents' mental state language and child gender: A scoping review of developmental evidence

Mental state language (MSL) is an important mechanism through which children learn about their social world and place within it. Previous research has suggested that parents may use MSL differently towards children based on their child's gender. However, findings are inconsistent. This scoping review explores the consistency of reported differences in parents' MSL use as a function of children's gender while exploring the methodological variables that may provide insights into these differences. Based on a review of the 27 studies included, 12 found a significant relationship between child gender and parents' MSL, while the remaining did not. The included studies used a range of methodological approaches to elicit MSL. This scoping review allows researchers and practitioners to reflect upon assumptions regarding the associations between child gender and parents' MSL. Further, we call for the use of diverse and informed approaches when studying these associations from a developmental perspective in the future.

Gender identity importance in cisgender and gender diverse adolescents in the US and Canada

Transgender adolescents often categorize themselves in the same way that cisgender adolescents do-that is, as girls/women and boys/men. Potential differences in the extent to which these self-categorizations matter to transgender and cisgender adolescents, however, have yet to be explored, as has the relative importance transgender adolescents place on their gender compared to their transgender self-categorization. In the current study, we explored self-reported identity importance in a sample of 392 primarily White (70%) and multiracial/ethnic (20%) 12-18-year-old (M = 15.02) binary transgender (n = 130), binary cisgender (n = 236), and nonbinary (n = 26) adolescents in the United States and Canada. Results revealed that binary transgender adolescents considered their gender self-categorization to be more important to them than both binary cisgender and nonbinary adolescents did. Most binary transgender adolescents rated their gender self-categorization as maximally important to them. Additionally, transgender adolescents considered their gender self-categorization to be more important to them than their transgender self-categorization (that is, their identification with the label "transgender"). These findings demonstrate that the identities that are often denied to binary transgender adolescents may be the very identities that are most important to them. Results also suggest that gender diverse adolescents with different gender identities may differ in the importance they place on these identities.

Memory biases for gender-typed images in a gender-diverse group of children

Self-socialization accounts of gender development suggest that children attend more to people of their own gender, activities associated with their own gender and stereotype-consistent examples in their environment. Evidence comes from research showing children's memory biases for such stimuli. This study sought to replicate these memory biases in 367 6- to 11-year-old transgender, cisgender and nonbinary children. Children were shown stereotype-consistent and counter-stereotypical images related to feminine- and masculine-typed activities performed by girls/women or boys/men. Results showed that transgender and cisgender children showed better recall for activities related to their own gender than the other gender. Neither group showed better recall for own-gender characters, and transgender children better recalled other-gender characters. None of the three groups better recalled stereotype-consistent than counter-stereotypical images in probed recall, although all groups showed better recall for counter-stereotypical than stereotype-consistent images in free recall. These findings provide partial support for self-socialization accounts of gender development.

What do measures of gender identity tell us about gender identity over time?

Gender identity is a multifaceted concept and is represented by a wide range of measures and constructs including both self-report and researcher observations of preferences and behaviours. However, despite their similar theoretical underpinning, gender identity measures are rarely found to correlate with one another, and contrasting patterns and trajectories are often found for each construct (Egan & Perry, Developmental Psychology, 37, 2001, 451). Therefore, this systematic review aimed to present a review of the longitudinal research evidence surrounding gender identity development in the absence of formal intervention. Using a systematic search strategy, 21 studies were identified. Narrative synthesis was used to synthesize the data collected in these studies and trajectories were explored for (1) self-identification measures of gender identity, (2) clothing preferences, (3) peer preferences, and (4) object/activity preferences. Overall, the results of this systematic review are consistent with wider research suggesting that distinct developmental patterns can be observed when using different constructs and measures of gender identity.

Rethinking Gender/Sex Identity

Until quite recently, investigations of gender/sex development operated from a baseline assumption that gender/sex is dichotomous or binary. Most such studies constructed gender/sex outside of or adjacent to specific cultures, and for the most part studied children from Western, Educated, Industrialized, Rich, Democratic (WEIRD) countries. In this paper I first advocate for four research guidelines-inclusivity, epistemic justice, materiality, and empiricism. I sketch out the historical background that still shapes contemporary studies into the psychology of gender/sex identity in infants and toddlers. Next, I point toward methods for the study of gender/sex in infants and toddlers that have the potential to make nonbinary development visible and to develop culturally diverse concepts of identity development. Finally, I challenge psychologists and others to view and operationalize the study of identity as a relational, phenomenological entity rather than a fixed feature of the individual psyche.

Egalitarian preferences in young children depend on the genders of the interacting partners

In decisions between equal and unequal resource distributions, women are often believed to be more prosocial than men. Previous research showed that fairness attitudes develop in childhood, but their-possibly gendered, developmental trajectory remains unclear. We hypothesised that gender-related fairness attitudes might depend not only on the gender of the Allocator, but also on that of the Recipient. To examine this, we tested 332 three to 8-year-old children in a paired resource allocation task, with both boys and girls acting as Allocators and Recipients. We indeed found gender-related effects: girls more than boys aimed to reduce advantageous inequity, and Allocators of both genders were more averse against male Recipients being better off. Notably, older girls exhibited an envy bias, i.e., they tolerated disadvantageous inequity more when the resource allocation was in favour of other girls than when it favoured boys. We also observed a gender-related spite gap in boys aged 7-8: unlike girls, boys treated other boys with spite, i.e., they valued unfair distributions in their own favour over equal outcomes, especially if rejecting advantageous inequity was costly. This pattern hints at contextualised gender-related fairness preferences that evolve with age that could depend on same- and cross-gender past interaction experiences.

Gender Development in Gender Diverse Children

Within "mainstream" developmental science, gender researchers largely study the developmental trajectory of children considered to be "gender-typical", while research housed primarily in psychiatry and clinical psychology often documents the trajectories of gender diverse children. This article aims to bridge the studies of gender diversity and "mainstream" gender development. First, we review literature on the development of four commonly studied subgroups of gender diverse children - children referred to medical clinics because of their gender identity and expression, transgender children, female children with congenital adrenal hyperplasia, and tomboys - highlighting how these gender trajectories do or do not align with modal developmental patterns. We then describe social, cognitive, and biological determinants of gender in light of their implications for understanding diverse gender development. Finally, we note methodological suggestions for future research, with an eye toward better integrating research on gender diversity into "mainstream" gender development research.

Scientific authorship by gender: trends before and during a global pandemic

Many fields of science are still dominated by men. COVID-19 has dramatically changed the nature of work, including for scientists, such as lack of access to key resources and transition to online teaching. Further, scientists face the pandemic-related stressors common to other professions (e.g., childcare, eldercare). As many of these activities fall more heavily on women, the pandemic may have exacerbated gender disparities in science. We analyzed self-identified gender of corresponding author for 119,592 manuscripts from 151 countries submitted January 2019 to July 2021 to the Institute of Physics (IOP) portfolio of 57 academic journals, with disciplines of astronomy and astrophysics, bioscience, environmental science, materials, mathematics, physics, and interdisciplinary research. We consider differences by country, journal, and pre-pandemic versus pandemic periods. Gender was self-identified by corresponding author for 82.9% of manuscripts (N = 99,114 for subset of submissions with gender). Of these manuscripts, authors were 82.1% male, 17.8% female, and 0.08% non-binary. Most authors were male for all countries (country-specific values: range 0.0-100.0%, median 86.1%) and every journal (journal-specific values range 63.7-91.5%, median 83.7%). The contribution of female authors was slightly higher in the pandemic (18.7%) compared to pre-pandemic (16.5%). However, prior to the pandemic, the percent of submissions from women had been increasing, and this value slowed during the pandemic. Contrary to our hypothesis, we did not find that manuscript submissions from women decreased during the pandemic, although the rate of increased submissions evident prior to the pandemic slowed. In both pre-pandemic and pandemic periods, authorship was overwhelmingly male for all journals, countries, and fields. Further research is needed on impacts of the pandemic on other measures of scientific productivity (e.g., accepted manuscripts, teaching), scientific position (e.g., junior vs. senior scholars), as well as the underlying gender imbalance that persisted before and during the pandemic.
