The gender similarities hypothesis

Risk Taking and Accidents in Adventure Sports Across Males and Females

The popularity and practice of adventure physical activities in nature (APAN) have risen substantially in the past 20 years. At the same time, the number of events leading to serious injury has increased substantially. Several factors account for the occurrence of such events, albeit individual differences in personality traits together with sex differences appear as important intervening factors. Social or evolutionary approaches might be helpful to explain the higher risk taking and accidents in males compared with females. We evaluated whether sex similarities or differences emerged when relating individual traits with accidents in adventure sports, with a sample of Spanish practitioners of adventure sports (337 males, 168 females). Males endured more accidents than females albeit scoring similarly in risk taking. There was a more robust association between age and deliberate risk taking for males than for females, and risk taking was a more robust predictor of accidents for males than for females. Further, males remained more prone than females to endure an accident when scoring high in risk taking.

Analysis of the Development of Gender Stereotypes and Sexist Attitudes Within a Group of Italian High School Students and Teachers: A Grounded Theory Investigation

Gender stereotypes and sexist attitudes continue to persist in educational settings, with significant implications for students' achievement and well-being. This study aimed to investigate the development of gender stereotypes and sexist attitudes among Italian high school students and trainee teachers. A series of focus groups were conducted with a group of Italian school students and trainee teachers to uncover the complex interplay of individual, interpersonal, institutional, and societal factors that contribute to the formation and perpetuation of these biases. Analysis was conducted using a grounded theory approach. The findings reveal a nuanced and multifaceted understanding of the issue, highlighting the critical role of teacher attitudes, peer influence, and broader cultural norms in shaping students' perceptions and behaviors. This study offers insights for educators, policymakers, and researchers seeking to address gender inequities in education and promote more inclusive and equitable learning environments.

Women are worse off in developing and recovering from temporomandibular disorder symptoms

Decision-making for temporomandibular disorders (TMDs) is reported being a clinical challenge, partly due to uncertainities in assessment of long-term prognosis. Therefore, our aim was to explore variations over time in TMD symptoms and possible sex or age differences. In this cohort study, data were prospectively collected 2010-2017 from the general population in Västerbotten, Northern Sweden. Adults were eligible if they had undergone at least two routine dental check-ups that included screening for TMDs (3Q/TMD) from which states were defined as absence or presence of TMD pain and/or jaw catching/locking. The rate of transitions was estimated between TMD states within a time span of one year. A total of 94,769 individuals were included (49.9% women) with 205,684 repeated visits and 9,006 state transitions recorded over the 8-year period. Compared to men, women had higher rates of transitions from no TMDs to any TMD symptoms. Furthermore, women had a lower rate of transition from TMD pain only to no TMDs. The finding of a poorer prognosis in women, as well as previously reported potential gender differences in pain perception and reporting, reinforces that gender differences should be accounted for in the treatment planning stage for patients with onset of TMDs.

The role of gender in the association between sensory impairments and well-being, depression symptoms, and relationship satisfaction among older adults

OBJECTIVES

This study aimed to investigate the impact of sensory impairments on well-being, depression symptoms, and relationship satisfaction among older adults, and to examine whether these associations vary by gender.

METHOD

The study analyzed a sample of 640 Danish individuals aged 60 and older. Multilevel modeling was conducted using PROC MIXED in SAS to assess the impact of sensory impairments on well-being, depression symptoms, and relationship satisfaction. A two-step approach was employed to evaluate the main effects and interaction terms of sensory impairments and gender, controlling for covariates such as age, education, and relationship length.

RESULTS

Both vision and hearing impairments were significantly associated with lower well-being and higher depression symptoms in men and women. However, a gender difference was observed for the association between vision impairment and relationship satisfaction: greater vision impairment was associated with lower relationship satisfaction among men but not among women.

CONCLUSION

The findings add nuance to the understanding of how sensory impairments may affect older men and women, highlighting both gender similarities and differences. The study also discusses possible interpretations of the findings, suggesting that social and cultural factors may influence how sensory impairments affect mental and relational health outcomes differently for men and women.

Girls and Boys Typically Have Similar Math Value Beliefs: Replication Evidence Across Historical Time, High School, and Racial/Ethnic Groups

INTRODUCTION

Individuals' math value beliefs are theorized to influence who persists in STEM. However, the existing findings on gender differences in adolescents' math value beliefs are inconsistent. The goal of this study was to use three existing datasets to help clarify when gender differences emerge for high school adolescents and for whom (i.e., adolescents across historical time, grade level, and race/ethnicity). Specifically, we examined the extent to which gender differences in adolescents' math value beliefs (i.e., interest, utility, and attainment) replicated (1) across three datasets spanning the 1990s to 2010s, (2) from 9th-12th grade, and (3) within each of the four largest U.S. racial/ethnic groups (i.e., Asian, Black, Latine, and White adolescents).

METHODS

We tested these aims with three existing longitudinal U.S. datasets: the California Achievement Motivation Project (CAMP) (n = 8855), the Childhood and Beyond Study (CAB) (n = 582), and the High School Longitudinal Study (HSLS) (n = 21,000). Students were in high school (9th-12th grade) and half were girls (49%-53%). All three datasets included measures with the same or similar math value belief items, making conceptual replication possible.

RESULTS AND CONCLUSIONS

Overall, we did not find strong evidence for meaningful gender differences in adolescents' math value beliefs overall. We did find meaningful gender differences in the oldest data set (CAB). When examined within each racial/ethnic group, we found no evidence of gender differences in math value beliefs among Black or Latine adolescents, but some differences among Asian and White adolescents. The findings align with the gender similarities hypothesis, suggesting adolescent girls and boys had similar math value beliefs.

Mirror writing of digits: Is there a difference between boys and girls?

The neurological process of mirror generalization in memory, also known as mirror symmetrization, presents a real dilemma for typically developing 5- to 6-year-olds when learning to write characters (digits and letters). Should they write the digit 3 oriented to the left, that is correctly, or to the right, which leads to its mirror image ε? It has been anecdotally suggested that boys are more prone to mirror-writing than girls, but there is no scientific evidence for this idea. The present article gathers data from 691 children in the upper section of the French école maternelle (age between 5 and 6 ½), who each wrote the digits 0 to 9 four times under dictation and not necessarily in their natural order. Both simple and complex (mixed-effects linear regression) statistical comparisons on the percentages of digit reversal, show a substantial difference: girls produce more mirror reversals than boys. And yet the reversal curves as a function of the digits are quite similar between the two sexes (r = .97). It has been proposed that mirror reversal of characters results from the left orientation of some of them (e.g., 3, 7, J, Z), that is, in an orientation contrary to the direction of writing in our Western cultures. The present investigation shows that (1) this character orientation hypothesis (choosing to write characters in the same orientation as sentence writing) better explains reversals than the counterclockwise hypothesis (children are trained to draw circles counter-clockwise to prepare for attached cursive writing); (2) the study of the stability of reversals additionally supports the explanation of mirror writing by the left orientation of the digits (1, 2, 3, 7 and, less obviously, 9); but (3) neither of the preceding findings (left-right orientation and stability) provided a convincing explanation for the aforementioned gender difference.

Gender-specific perception of job stressors and resources: a structural equation model-based secondary analysis

Objective

Stress is an extensive issue in modern society, affecting men and women differently. A better understanding of these patterns is required within the work context. Therefore, this study aimed to identify gender differences in the effects of stressors (quantitative demands, qualitative demands, working time) and resources (job control, quality of leadership, co-worker support) on subjective perceived stress across occupational groups.

Methods

This study was conducted as a secondary data analysis based on the 'German Study on Mental Health at Work' data. The national representative cross-sectional sample included 4,118 employees. The data were analyzed using structural equation modeling.

Results

Correlations between quantitative demands, working time, co-worker support, quality of leadership, job control, and subjective perceived stress were first confirmed for a total sample of employees. Gender differences in these interactions were then analyzed using multi-group equation modeling and a gender-stratified sample. Men and women showed an increase in subjective perceived stress for high quantitative demands. This increase was more prominent for men. Women further showed an increase in subjective perceived stress in response to long working time. High co-worker support, quality of leadership, and job control had stress-reducing effects but did not result in significant gender differences. No association was found between qualitative demands and subjective perceived stress.

Conclusion

The results underline that not all working conditions significantly impact stress for both genders and gender differences exist only within the stressors. Hence, gendered strategies may only be required in some constellations. However, specific contexts require integrating gendered approaches in research and operational practice.

Positive Outcomes of Long-Term Relationship Satisfaction Trajectories in Stable Romantic Couples: A 10-Year Longitudinal Study

Growing evidence challenges the longstanding assumption of a universal decline in relationship satisfaction for all couples by demonstrating variability in the change. However, knowledge about how differential long-term trajectories of relationship satisfaction are associated with positive individual functioning is lacking. Using dyadic latent class growth analysis, we studied long-term trajectories of relationship satisfaction of N = 300 mixed-gender couples over 10 years and examined positive outcomes in latent subgroups. At the final assessment, partners reported on positive outcomes, specifically affect, mental health, and life satisfaction. Depending on their subgroup membership, couples systematically differed: Couples in the subgroup with high initial and relatively stable relationship satisfaction reported the most favorable outcomes-more positive affect, better mental health, and higher life satisfaction-as compared to subgroups with declining and/or lower relationship satisfaction. The findings show the importance of considering the variability in long-term relationship satisfaction trajectories and point to their relevance for positive functioning.

Exploring the Impact of Sex and Gender in Brain Function: Implications and Considerations

INTRODUCTION

Sex and gender are crucial variables in understanding brain development and disease. Biological sex is determined by genetic and hormonal factors, whereas gender is a multidimensional construct shaped by social and cultural influences. The interplay of these factors contributes to sex-specific susceptibilities and disease progression in psychiatric and neurological disorders. However, sex and gender are often considered as a single variable, which can lead to biased data analysis and interpretation. This commentary aims to analyze how sex and gender influence brain structure and function, with implications for personalized medicine, research, and the development of gender-sensitive clinical guidelines.

METHODS

Findings from various studies employing neuroimaging techniques and animal models are discussed, as well as the impact of biological sex, gender, environmental, cultural, and social factors on brain development, organization, and behavior.

RESULTS

Evidence suggests that sex differences in brain structure and function are not only genetically determined but are also influenced by gender-related experiences and societal contexts. Importantly, discrepancies between male and female brains are reduced in gender-equal societies. Preclinical studies play a pivotal role in determining the influence of biological sex, independent of gender, in different disease models.

CONCLUSION

The findings underscore the need to consider both sex and gender in research and clinical practice to avoid biases and promote equitable health outcomes. Moving forward, we advocate for gender-sensitive approaches to be integrated into brain research and in clinical guidelines to achieve personalized and precision medicine.

Gender Differences in Variability in Intimate Relationship Satisfaction: A Secondary Analysis and Meta-Analysis

There is a long-standing interest in gender differences in satisfaction in intimate relationships. Whereas prior research has focused on gender differences in central tendency (i.e., means), we conducted two studies - a secondary analysis of data from a probability sample of Australian married couples and a meta-analysis - to examine gender differences in variability (i.e., variances). We hypothesized that compared to males, females would demonstrate greater variability in intimate relationship satisfaction (i.e., greater female variability hypothesis), particularly at lower levels of relationship satisfaction. Results from a secondary analysis of data from 2,711 married couples in the Household, Income and Labour Dynamics in Australia (HILDA) survey and from a meta-analysis of 20 years of research (k = 171, N = 84,976), including independent samples from 33 countries, indicated that relative to males, females reported greater variability in relationship satisfaction. Obtained effect sizes (female-to-male variance ratios [VRs] of 1.42 for the HILDA sample and 1.19 for the meta-analysis) were larger than proposed cutoffs for meaningful group differences in variability. Analysis of tail ratios (ratios of the relative proportion of females divided by the relative proportion of males in the distributional tail regions) in the HILDA sample indicated that gender differences in variability were greater at lower (versus higher) levels of satisfaction. Findings support the greater female variability hypothesis and suggest that by focusing only on gender differences in means, the existing literature has underestimated gender differences in intimate relationship satisfaction.

Gender variability in palpation performance for temporomandibular disorders with three different methods: An experimental study

Gender differences in pain reporting and prevalence have been demonstrated. As gender of examiner also affects reporting of pain on palpation, the aim of this study was to evaluate the effects of examiner gender on palpation performance using three different palpation methods. Examiners of both genders were instructed on the correct technique for each palpation method by either a female or male instructor. The target was to achieve a pressure of 100 kPa, corresponding to the 1 kg of force for muscle palpation described in the diagnostic criteria for temporomandibular disorders (DC/TMD). All examiners performed traditional palpation with the index finger, palpation with a palpometer, and a novel bimanual palpation with visual feedback, in a randomized order. The examiner's gender, and its interaction with the gender of the instructor did not significantly affect magnitude, accuracy, or precision of the pressure applied. The method of palpation was the only factor that significantly impacted all metrics. The palpometer achieved the lowest palpation magnitude (mean pressure applied = 113.7  kPa, 95% CI: 109.8-117.6), the highest accuracy (absolute difference = 15.7  kPa, 95% CI: 12.3-19.1), and the highest precision (mean coefficient of variation = 6.8, 95% CI: 6.0-7.6), followed by bimanual palpation and traditional palpation. The results suggest that gender differences in pain reporting in patients are not likely to be a result of the technical aspects associated with the gender of the examiner. Instead, these differences may be attributed to other factors, such as sociocultural influences.

The Mediating Role of Work-Family Interface in the Relationship Between Quantitative Workload and Interpersonal Strain: A Gender-Based Moderation Analysis

PURPOSE

The study investigates the role of work-family interface dimensions (negative work-to-family interface, NEGWIF; negative family-to-work interface, NEGFIW; positive work-to-family interface, POSWIF; and positive family-to-work interface, POSFIW) as mediators in the relationship between workload and interpersonal strain. In addition, we examined the moderating effect of gender.

DESIGN/METHODOLOGY/APPROACH

319 Italian employees working in the commercial sector participants completed a self-report questionnaire. The hypothesized models were tested using PROCESS Macro.

FINDINGS

Work-family interface dimensions totally mediated the relationship between workload and interpersonal strain. Moderating influence of gender was found. Gender moderated the relationship between workload and three work-family interface dimensions-NEGWIF, POSWIF and POSFIW-in the indirect relationship between workload and interpersonal strain.

RESEARCH LIMITATIONS/IMPLICATIONS

This study suggests to organizations that moderate workload and family-friendly policies can act as a protective factor against interpersonal strain. The limitations of the study are the use of self-report measures and the cross-sectional design.

ORIGINALITY/VALUE

This research attempted to fill the gap in interpersonal strain and relationships with the work-family interface.

Sex differences in the human brain related to visual motion perception

BACKGROUND

Previous studies have found that the temporal duration required for males to perceive visual motion direction is significantly shorter than that for females. However, the neural correlates of such shortened duration perception remain yet unclear. Given that motion perception is primarily associated with the neural activity of the middle temporal visual complex (MT+), we here test the novel hypothesis that the neural mechanism of these behavioral sex differences is mainly related to the MT+ region.

METHODS

We utilized ultra-high field (UHF) MRI to investigate sex differences in the MT+ brain region. A total of 95 subjects (48 females) participated in two separate studies. Cohort 1, consisting of 33 subjects (16 females), completed task-fMRI (drafting grating stimuli) experiment. Cohort 2, comprising 62 subjects (32 females), engaged in a psychophysical experiment measuring motion perception along different temporal thresholds as well as conducting structural and functional MRI scanning of MT+.

RESULTS

Our findings show pronounced sex differences in major brain parameters within the left MT+ (but not the right MT+, i.e., laterality). In particular, males demonstrate (i) larger gray matter volume (GMV) and higher brain's spontaneous activity at the fastest infra-slow frequency band in the left MT+; and (ii) stronger functional connectivity between the left MT+ and the left centromedial amygdala (CM). Meanwhile, both female and male participants exhibited comparable correlations between motion perception ability and the multimodal imaging indexes of the MT+ region, i.e., larger GMV, higher brain's spontaneous activity, and faster motion discrimination.

CONCLUSIONS

Our findings reveal sex differences of imaging indicators of structure and function in the MT+ region, which also relate to the temporal threshold of motion discrimination. Overall, these results show how behavioral sex differences in visual motion perception are generated, and advocate considering sex as a crucial biological variable in both human brain and behavioral research.

The Chinese version of the physical activity questionnaire for adolescents: a psychometric validity, reliability, and invariance study

BACKGROUND

The Physical Activity Questionnaire for Adolescents (PAQ-A) is one of the most commonly used questionnaires for assessing adolescents' levels of moderate to vigorous physical activity (PA). Although a Chinese version of the PAQ-A (comprising nine items) exists, it has been assessed for only internal consistency coefficients, test-retest reliability, and correlations with the GT3X + accelerometer. Therefore, this study aimed to evaluate the psychometric properties of the Chinese version of the PAQ-A among Chinese adolescents.

METHODS

This study included three samples of 1,101 secondary school students (12-19 years old). The first sample consisted of 518 participants (50.4% males, 49.6% females) for correlation tests and exploratory factor analysis (EFA). The second sample consisted of 227 participants (55.75% males, 44.24% females) for confirmatory factor analysis (CFA), convergent validity, and sample size invariance tests. The third sample consisted of 356 participants (54.50% male, 45.50% female) for the internal consistency reliability test, invariance test (cross sample size, education level and gender), and t-test.

RESULTS

Pearson correlation analysis of the PAQ-A indicated that all the total-item correlations exceeded 0.2, indicating good consistency across the items. Subsequent EFA of the Chinese version of the PAQ-A revealed a two-factor structure. CFA subsequently validated this structure. One of the items exhibited a standardized loading below 0.4 and was excluded. The exclusion of this item resulted in increased standardized loadings for the remaining items, ranging from 0.40 to 0.82, which indicates improved fit indices. This adjustment underscores the questionnaire's satisfactory convergent validity and robust discriminant validity. The overall Cronbach's alpha was 0.821, with the values for the first and second factors being 0.757 and 0.716, respectively. The questionnaire demonstrated stable invariance across sample sizes and education levels and additionally showed partial scalar invariance across genders. A t-test revealed a significant difference between males and females, which aligns with previous findings. These findings supported the construct validity of the questionnaire.

CONCLUSION

This study validated the Chinese version of the PAQ-A for assessing adolescent PA in China, with a two-factor structure improved by removing one item.

Promoting Well-Being from a Gender Perspective: A Systematic Review of Interventions Using Digital Tools and Serious Games

Gender inequalities continue to pose a significant issue across various aspects of life, adversely impacting the well-being of both females and males. These disparities often stem from the ingrained gender stereotypes passed down to young individuals through parental guidance, educational systems, and media portrayal. For this reason, within the psycho-pedagogical field, various intervention models have been developed in recent years, leveraging digital tools to combat stereotypes and enhance well-being among adolescents. The aim of this systematic review is, therefore, to identify studies employing digital tools, particularly serious games, to promote well-being from a gender perspective. The review was conducted using the PRISMA guidelines and collected articles from four databases: Scopus, the Web of Science, PubMed, and PsycInfo. The screening process culminated in the selection of 15 articles. The findings reveal a proliferation of platforms, applications, and programs aimed at promoting well-being by addressing emotional, cognitive (or mental), physical, and sexual health dimensions. Some contributions emphasize nurturing positive attributes within individuals or fostering empowerment as a precursor to well-being. Additionally, certain articles delve into the effect of the COVID-19 pandemic on the well-being of young men and women; in particular, the authors investigated the effect of using an app to improve well-being before and after the pandemic. This systematic review aims to expand the knowledge base on technology-based interventions for social change. It endeavors to empower educators and advance the creation of innovative, evidence-based digital tools that can enhance positive mental health, promote gender equality education, and foster the well-being of young people.

Gender differences in operational and cognitive abilities

Introduction

Gender differences in cognitive and operational abilities have been identified. Yet, their interrelationship remains underexplored. This prevents tailored evidence-based selection, allowing discrimination to persist.

Methods

Data from a test battery of operational and cognitive tests was analyzed. In total 2,743 aviation pilot candidates' test scores were analyzed.

Results

Males had a significantly higher score on mental spatial ability, memory retention, abstract problem solving, multitasking ability (MU), and manual spatial ability (MSA); and females on perceptual speed. Correlations between MU and MSA [difference = 0.269 (95% CI: 0.114; 0.405)] and between MSA and perceptual speed [difference = 0.186 (95% CI: 0.027; 0.332)] were significantly stronger among female applicants. A high MSA score was more predictive of a high score on MU, Perceptual speed, and Memory for female compared with male applicants (p < 0.002 for the MSA score × sex interaction effect in all three cases).

Discussion

Interpretation of test scores in between genders potentially may need to look different for final selection decisions for operational professions, as female test profiles were shown to exhibit greater homogeneity.

The impact of Philosophy for Children (P4C) activities on enhancing the speaking skills of gifted students

The aim of this study was to investigate the impact of Philosophy for Children (P4C) activities integrated into Turkish lessons on the speaking skills of gifted students. Both quantitative and qualitative data were collected through interviews and various scales, employing a mixed-method design. The results indicated that students had positive feelings about P4C, including appreciation, curiosity, surprise, excitement, self-confidence, and empathy. They believed that P4C enhanced their problem-solving, creativity, questioning, effective speaking, and collaboration skills. However, some students also expressed negative views, tough less frequently, citing issues such as nonsense, limited time, the necessity of prior knowledge, and lack of idea diversification. Quantitative data revealed that P4C activities significantly improved the speaking skills of gifted students and notably reduced their speaking anxiety. Additionally, sex and program variables showed no significant effect on speaking skills and speaking anxiety.

Delayed modulation of alpha band activity increases response inhibition deficits in adolescents with AD(H)D

Deficiencies in inhibitory control are one of the hallmarks of attention-deficit-(hyperactivity) disorder (AD(H)D). Response inhibition demands can become increased through additional conflicts, namely when already integrated representations of perception-action associations have to be updated. Yet, the neural mechanisms of how such conflicts worsen response inhibition in AD(H)D are unknown, but, if identified, could help to better understand the complex nature of AD(H)D-associated impulsivity. We investigated both behavioral performance and EEG activity in the theta and alpha band of adolescents (10-18 years of age) with AD(H)D (n = 28) compared to neurotypical (NT) controls (n = 33) in a conflict-modulated Go/Nogo paradigm. We used multivariate pattern analysis (MVPA) and EEG-beamforming to examine how changes in representational content are coded by oscillatory activity and to delineate the cortical structures involved in it. The presented behavioral and neurophysiological data show that adolescents with AD(H)D are more strongly affected by increased response inhibition demands through additional conflicts than NT controls. Precisely, AD(H)D participants showed higher false alarm rates than NT controls in both, non-overlapping and overlapping Nogo trials, but performed even worse in the latter. This is likely due to an inefficient updating of representations related to delayed modulations of alpha band activity in the ventral stream and orbitofrontal regions. Theta band activity is also modulated by conflict but was not differentially affected in the two groups. By this, the present study provides novel insights into underlying neurophysiological mechanisms of the complex nature of response inhibition deficits in adolescents with AD(H)D, stressing the importance to examine the interplay of theta and alpha band activity more closely to better understand inhibitory control deficits in AD(H)D.

Is the Behavioural Gender Gap Decreasing? Evidence from Food Consumption in Swiss Single-Person Households

While Switzerland has made some progress over the past few decades in treating men and women more equally, this study intends to find out whether Swiss men and women's food consumption patterns also converged between 1990 and 2017. After analysing 1.8 million observations of one-member households' food baskets, we found that gender gaps are increasing significantly for 16 of 70 studied foods, decreasing significantly for another 16 of 70 studied foods and not changing significantly for more than half of the studied foods. On average, the gender gap in food consumption in Switzerland has increased over time. We conclude that behavioural differences between genders and culturally induced gender differences (e.g., unequal career chances) are largely unrelated.

Sex-related variability of white matter tracts in the whole HCP cohort

Behavioral differences between men and women have been studied extensively, as have differences in brain anatomy. However, most studies have focused on differences in gray matter, while white matter has been much less studied. We conducted a comprehensive study of 77 deep white matter tracts to analyze their volumetric and microstructural variability between men and women in the full Human Connectome Project (HCP) cohort of 1065 healthy individuals aged 22-35 years. We found a significant difference in total brain volume between men and women (+ 12.6% in men), consistent with the literature. 16 tracts showed significant volumetric differences between men and women, one of which stood out due to a larger effect size: the corpus callosum genu, which was larger in women (+ 7.3% in women, p = 5.76 × 10-19). In addition, we found several differences in microstructural parameters between men and women, both using standard Diffusion Tensor Imaging (DTI) parameters and more complex microstructural parameters from the Neurite Orientation Dispersion and Density Imaging (NODDI) model, with the tracts showing the greatest differences belonging to motor (cortico-spinal tracts, cortico-cerebellar tracts) or limbic (cingulum, fornix, thalamo-temporal radiations) systems. These microstructural differences may be related to known behavioral differences between the sexes in timed motor performance, aggressiveness/impulsivity, and social cognition.

Statistical analysis of the effect of socio-political factors on individual life satisfaction

Life satisfaction refers to an individual's cognitive evaluation of the quality of their life. The aim of the present study is to develop the current understanding of how perceived corruption, attitudes toward migration, perceived security, and strength of national identity influence life satisfaction. Additionally, the study examines how demographic variables of relationship status, social class, sex, religious affiliation, and country impact life satisfaction in the provided cultural context. Ordinal logistic regression analysis, Confirmatory Factor Analysis, and Structural Equation Modeling are used to analyze data from the World Values Survey. Findings from the analyses indicate that perceived corruption, perceived security, and strength of national identity have a significant impact on life satisfaction, whereas migration has an indirect effect on life satisfaction through perceived security. The present research can develop our current understanding of life satisfaction from a socio-political perspective.

Gender differences in mathematics anxiety: A meta-analysis of Chinese children

Mathematics anxiety (MA) is a widespread phenomenon that affects an individual's learning of mathematics. MA between different genders has been of great interest to researchers. Meta-analysis was used to examine the relationship between MA and gender in Chinese children, along with the influencing factors. After literature search and screening, 83 papers and 91 independent samples met the inclusion criteria. The results of the main effect test of the random effect model revealed a correlation of significant levels between MA and gender, r = -0.131, 95%CI [-0.158, -0.105], Z = -9.508, and p < 0.001. Girls had higher MA than boys. The outcomes of the moderating effect test indicated that the moderating effect of age, economic region and measurement instrument in the relationship between MA and gender was significant. But the moderating effect of period was not significant. Specifically, gender differences in MA were greater at the middle school compared to the elementary school. And the greatest correlation between children's MA and gender was in the western region. The gender difference of MA measured by different instruments varied.

Longitudinal associations between Latine parents' support and their adolescents' science motivation and STEM career expectations

INTRODUCTION

Parents' science support and adolescents' motivational beliefs are associated with adolescents' expectations for their future occupations; however, these associations have been mostly investigated among White, middle-class samples. Framed by situated expectancy-value theory, the current study investigated: (1) the associations between parents' science support in 9th grade and Latine adolescents' science intrinsic value, utility value, and STEM career expectations in 11th grade, and (2) whether these indicators and the relations among them differed by adolescents' gender and parents' education.

METHODS

Study participants included Latine adolescents (n = 3060; Mage = 14.4 years old; 49% female) in the United States from the High School Longitudinal Study of 2009.

RESULTS

Analyses revealed a significant, positive association between parents' science support and Latine adolescents' science utility value. Additionally, there was a significant, positive association between parents' science support and Latinas' science intrinsic value, but not for Latinos' science intrinsic value. Latine adolescents' science utility value, but not their science intrinsic value, predicted their concurrent STEM career expectations. Though there were no significant mean level differences in adolescents' science utility value or parents' science support based on adolescents' gender, the measure of adolescents' science intrinsic value varied across girls and boys. Finally, adolescents whose parents had a college degree received greater science support from parents compared to adolescents whose parents had less education than a college degree.

CONCLUSION

Findings suggest parents' science support and adolescents' intrinsic and utility values have potential associations with Latine adolescents' STEM career expectations near the end of high school.

Gender Inequality is negatively associated with academic achievement for both boys and girls

To examine the role of inequality in academic achievement, we analyse a cross-national dataset including data from three cycles from 2012 to 2018 from the PISA, an international assessment of 15-year-old students' math, reading, and science performance. The Gini coefficient and gender inequality index (GII) were used as metrics for a country's economic inequality and gender inequality, respectively. The results show that gender inequality has a negative association with academic achievement for both boys and girls. Moreover, gender inequality has a stronger association with academic achievement than does economic inequality. We also find that gender inequality in reproductive health may contribute substantially to the association between gender inequality and academic achievement. Despite substantial advances in gender equality worldwide, multisectoral and multilevel approaches from the community to the country level are needed to ensure substantial long-term reductions in economic, gender, and educational inequalities.

Spelling development of children with and without reading difficulties throughout elementary grades: evidence from the Greek orthography

The purpose of this longitudinal study was to examine the development of spelling in a large sample (N = 503, boys: N = 219) of Greek-speaking children with (N = 41) and without (N = 462) reading difficulties. Children were initially tested in Grades 2-4 and then at five consecutive measurement points over a 3-year period, focusing on how initial reading ability, grade, and gender may moderate the rate of spelling growth. Individual growth curve modeling revealed continuous growth of spelling performance in the total sample, although the growth rate decreased over time for children first tested in Grades 3-4. Spelling growth rate was also significantly slower among children with reading difficulties between Grades 2-4 and 3-5. The two reading groups displayed similar growth rates between Grades 4 and 6. Spelling growth rates did not vary significantly with gender. Overall, our study highlights the persistence of spelling difficulties even after 6 years of systematic teaching in children with reading difficulties. The severe and persistent spelling deficits of Greek-speaking children with reading difficulties may be attributed to the rich morphological system of the Greek language, the intermediate Greek orthographic transparency (in the direction of writing), and their limited experience with print.

Threat sensitivity in emotion dynamics: Negativity effects and sex differences

Evolutionary theorizing has given rise to the idea that responding to any particular threat may be more mandatory than responding to any particular reward. The present three experiments (total N = 375) sought to provide support for this perspective in an emotion dynamics task in which participants continuously rated their affective state in response to appetitive (reward-related) versus aversive (threat-related) images. Even when equating images for arousal and extremity, several negativity effects (e.g., steeper reactivity slopes in response to aversive images) were found. These negativity effects can serve as an experimental model of threat sensitivity, which should predispose some individuals, more than others, to symptoms related to fear and anxiety. This point was made with respect to sex differences, given that women (relative to men) are diagnosed with anxiety disorders at higher rates. Sex differences were pronounced and extensions of this work, both basic and applied, are proposed.

Sex differences in brain excitability revealed by concurrent iTBS/fNIRS

Sex differences have been claimed an imperative factor in the optimization of psychiatric treatments. Intermittent theta-burst stimulation (iTBS), a patterned form of repetitive transcranial magnetic stimulation, is a promising non-invasive treatment option. Here, we investigated whether the real-time neural response to iTBS differs between men and women, and which mechanisms may mediate these differences. To this end, we capitalized on a concurrent iTBS/functional near-infrared spectroscopy setup over the left dorsolateral prefrontal cortex, a common clinical target, to test our assumptions. In a series of experiments, we show (1) a biological sex difference in absolute hemoglobin concentrations in the left dorsolateral prefrontal cortex in healthy participants; (2) that this sex difference is amplified by iTBS but not by cognitive tasks; and (3) that the sex difference amplified by iTBS is modulated by stimulation intensity. These results inform future stimulation treatment optimizations towards precision psychiatry.

Watch the tone of your voice! An exploration of dehumanization of women by gender nonconformity based on tone of voice, occupation and appearance

Dehumanization refers to the act of likening others to objects or animals. This, in turn, mitigates feelings of conscience, guilt, and moral obligation in the face of behaviors such as violence, mistreatment, or discrimination against the dehumanized individuals. The aim of this study is to determine the extent of which women with mismatching vocal tone, occupation and appearance to their gender expectations are dehumanized by others. To achieve this, we conducted a between-groups factorial design experiment. In the experiment, participants looked at the photo and listened to the voice of a target woman with either a gender congruent or incongruent vocal tone, occupation, or appearance. Participants indicated the extent to which human attributes were appropriate for this individual. The results revealed that the main effects of vocal tone and occupation were significant for both mechanistic and animalistic dehumanization. A target woman with a mismatched vocal tone and occupation was more dehumanized compared to those with a matched vocal tone and occupation. However, the interaction effect of vocal tone, occupation type, and appearance was found to be significant only for mechanistic dehumanization. Our study provides evidence to recent concerns that women may experience dehumanization due to their vocal tone and occupation.

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.

Disentangling the within- and between-person effects of personality on income for men and women

Understanding the relationship between personality and income is a topic of interest across multiple disciplines. Correlations between people's personalities and their incomes may arise because differences in stable personalities relate to income differences (between-person effects) or because changes in personality or income are later reflected in the other variable (within-person effects). The current research uses random-intercept cross-lagged panel models to disentangle the two sorts of effects to better understand the relationship between the six factors of personality and income. Using data from 6824 working-age adults in New Zealand across 4 years, we found between-person effects showing higher incomes were obtained by both men and women who were more extraverted, agreeable and open, and less neurotic. Within-person effects showed that earning a higher income was associated with higher neuroticism and lower extraversion over time, while higher extraversion was associated with a lower income over time.

Are there gender differences in promotion-prevention self-regulatory focus?

The purpose of this research is to examine gender differences in promotion/prevention self-regulatory focus, a dispositional motivational orientation with major implications for human functioning. First, a review of literature using social cognitive theory as a framework suggests that, driven by socialization processes, (1) women may on average be more prevention focused than men - meaning more vigilant to maintain a secure status quo, whereas (2) men may on average be more promotion focused than women - meaning more eager to advance to a better situation than their status quo. Second, we provide data to examine these possible gender differences in self-regulatory focus with secondary analyses of (a) our own existing data on dispositional regulatory focus and of (b) a large scale, representative panel study (LISS Survey). The data suggest a highly consistent difference with women being more prevention focused than men, while the difference in promotion focus is much smaller and is only found in European samples. Auxiliary data suggest promotion-focused women hold less traditional gender role beliefs as well as showing that regulatory focus partially explains examples of behavioural differences between men and women. The analysis of gender difference in regulatory focus sheds new light on gender differences and biases already known, and on regulatory focus, and as such opens up many new and important areas of future inquiry.

Sex-Specific Developmental Scales for Surveillance

BACKGROUND

Developmental surveillance, conducted routinely worldwide, is fundamental for early detection of children at risk for developmental delay. We aimed to explore sex-related difference in attainment rates of developmental milestones and to evaluate the clinical need for separate sex-specific scales.

METHODS

This is a cross-sectional, natiowide retrospective study, utilizing data from a national child surveillance program of ∼1000 maternal child health clinics. The main cohort, used for constructing sex-specific developmental scales, included all children born between January 2014 to September 2020, who visited maternal child health clinics from birth to 6 years of age (n = 839 574). Children with abnormal developmental potential were excluded (n = 195 616). A validation cohort included all visits between 2020 and 2021 (n = 309 181). The sex-differences in normative attainment age of 59 developmental milestones from 4 domains were evaluated. The milestones with a significant gap between males and females were identified, and the projected error rates when conducting unified versus sex-specific surveillance were calculated.

RESULTS

A new sex-specific developmental scale was constructed. In total, females preceded males in most milestones of all developmental domains, mainly at older ages. Conducting routine developmental surveillance using a unified scale, compared with sex-specific scales, resulted in potential missing of females at risk for developmental delay (19.3% of failed assessments) and over-diagnosis of males not requiring further evaluation (5.9% of failed assessments).

CONCLUSIONS

There are sex-related differences in the normative attainment rates of developmental milestones, indicating possible distortion of the currently used unified scales. These findings suggest that using sex-specific scales may improve the accuracy of early childhood developmental surveillance.

Diagnostic assessment of autism spectrum disorder in transgender and gender diverse youth

Objective: Higher prevalence of autism spectrum disorder (ASD) diagnosis and associated traits has been observed among transgender and gender diverse (TGD) youth, and the number of TGD youth requesting evaluation for autism is growing. This study explored the demographic and clinical profiles of TGD youth evaluated in a specialty autism clinic. Method: Retrospective autism evaluation results for 41 TGD youth aged 5-18 years and 67 cisgender-matched controls were included in the study. Results: Approximately, half of TGD youth were diagnosed with autism (TGDASD+; n = 19 vs. TGDASD-; n = 22). There were no group differences in sex assigned at birth, gender identity, FSIQ, race, or ethnicity. Compared to TGDASD- (allistic) youth, TGD autistics had significantly lower adaptive functioning and were more likely to have an IEP eligibility of ASD. Anxiety and mood disorders were more common in TGD youth, whereas language disorders were more prevalent in cisgender controls. Attention-Deficit/Hyperactivity Disorder (ADHD) was more common among TGDASD- youth (72%) than TGDASD+ youth (47%), though not significantly. Conclusions: TGD youth with school-based IEP eligibilities of ASD and lower adaptive functioning are more likely to be diagnosed with ASD upon medical evaluation. The combination of identifying as TGD and having ADHD may heighten suspicion for ASD. Asking about gender identity during autism evaluations for children middle school-aged and older is recommended.

"When" Versus "Whether" Gender/Sex Differences: Insights From Psychological Research on Negotiation, Risk-Taking, and Leadership

We present a conceptual framework of situational moderators of gender/sex effects in negotiation, risk-taking, and leadership-three masculine-stereotypic domains associated with gender/sex gaps in pay and authority. We propose that greater situational ambiguity and higher relevance and salience of gender/sex increase the likelihood of gender/sex-linked behaviors in these domains. We argue that greater ambiguity increases the extent to which actors and audiences must search inwardly (e.g., mental schema, past experience) or outwardly (e.g., social norms) for cues on how to behave or evaluate a situation and thereby widens the door for gender/sex-linked influences. Correspondingly, we propose that gender/sex effects on behavior and evaluations in these domains will be more likely when gender/sex is more relevant and salient to the setting or task. We propose further that these two situational moderators may work jointly or interactively to influence the likelihood of gender/sex effects in negotiation, risk-taking, and leadership. We conclude by discussing applications of our conceptual framework to psychological science and its translation to practice, including directions for future research.

After the trans brain: a critique of the neurobiological accounts of embodied trans* identities

This paper critically analyses three main neurobiological hypotheses on trans* identities: the neurobiological theory about the origin of gender dysphoria, the neurodevelopmental cortical hypothesis, and the alternative hypothesis of self-referential thinking and body perception. In this study I focus then the attention on three elements: the issue of (de)pathologisation, the idea of the trans brain, and the aetiology of trans* identities. While the neurobiological theory about the origin of gender dysphoria and the neurodevelopmental cortical hypothesis claim the existence of the trans brain, each offering its own neurobiological depiction, the hypothesis of self-referential thinking and body perception doesn't postulate a distinctive neurobiological trait for all trans* people. I problematize both portrayals of the trans brain departing from the findings and conceptualizations of the paradigm shifting brain mosaicism. Unlike the hypothesis of self-referential thinking and body perception that keeps the question of causation open, both the neurobiological theory about the origin of gender dysphoria and the neurodevelopmental cortical hypothesis situate the origin of trans* identities in the neurobiological domain. I challenge the biological deterministic framework in which this aetiology is inscribed from a dynamic processual entanglement perspective. Finally, concerning the issue of (de)pathologisation of trans* identities, an evolution can be seen in each of the hypothesis and among them, from the least to the most depathologising. However, I question their complete departure from a pathologising framework.

Are many sex/gender differences really power differences?

This research addresses the long-standing debate about the determinants of sex/gender differences. Evolutionary theorists trace many sex/gender differences back to natural selection and sex-specific adaptations. Sociocultural and biosocial theorists, in contrast, emphasize how societal roles and social power contribute to sex/gender differences beyond any biological distinctions. By connecting two empirical advances over the past two decades-6-fold increases in sex/gender difference meta-analyses and in experiments conducted on the psychological effects of power-the current research offers a novel empirical examination of whether power differences play an explanatory role in sex/gender differences. Our analyses assessed whether experimental manipulations of power and sex/gender differences produce similar psychological and behavioral effects. We first identified 59 findings from published experiments on power. We then conducted a P-curve of the experimental power literature and established that it contained evidential value. We next subsumed these effects of power into 11 broad categories and compared them to 102 similar meta-analytic sex/gender differences. We found that high-power individuals and men generally display higher agency, lower communion, more positive self-evaluations, and similar cognitive processes. Overall, 71% (72/102) of the sex/gender differences were consistent with the effects of experimental power differences, whereas only 8% (8/102) were opposite, representing a 9:1 ratio of consistent-to-inconsistent effects. We also tested for discriminant validity by analyzing whether power corresponds more strongly to sex/gender differences than extraversion: although extraversion correlates with power, it has different relationships with sex/gender differences. These results offer novel evidence that many sex/gender differences may be explained, in part, by power differences.

Romantic Attachment and Sexual Desire: The Role of Desire Target

Attachment insecurities are characterized by distinct approaches to intimacy and sex, yet their roles in sexual desire remain largely unexamined. Drawing from theories of attachment and behavioral motivation, the current study investigated the role of attachment insecurities in sexual desire and how that role differs by desire target. The Sexual Desire Inventory provided both a general dyadic desire measure and a measure differentiating between partner-specific desire and desire for an attractive potential sexual partner (attractive other desire). In a sample of 321 young adults (51% men), two structural equation models (SEMs) were compared, each with attachment predicting desire: a Dyadic Combined model and a Partner Type model. Models accounted for gender, relationship status, sexual identity, racial/ethnic identity, number of previous sexual partners, and measurement error. Preliminary confirmatory factor analyses indicated adequate factor loadings (>.40) for both desire measures, yet superior fit for the partner type measure. In the SEMs, the Partner Type model outperformed the Dyadic Combined model across all indices. Attachment avoidance predicted lower partner-specific desire, yet higher attractive other desire. Attachment anxiety predicted higher partner-specific desire, yet was unrelated to attractive other desire. Findings suggest the discomfort with intimacy characterized by attachment avoidance deters interest in sex with romantic partners, yet may enhance sexual interest in nonattachment figures. Several discrepant associations across desire measures indicate that distinguishing between desire targets is critical for fully understanding individual differences in desire. Partner-specific sexual desire may be a unique experience that should not be conflated with other forms of sexual desire.

Cross-lagged analysis of rumination and social anxiety among Chinese college students

BACKGROUND

Social anxiety, which is widely prevalent among Chinese college students, poses a significant barrier to their holistic psychological and physiological development. Although numerous cross-sectional studies have examined the relationship between rumination and social anxiety, there is still a gap in understanding their interplay over time. This longitudinal study aimed to explore and analyze the intricate interrelations between these two factors, with the ultimate goal of informing the development of effective mental health education interventions for university students.

METHODS

Using the Ruminative Responses Scale (RRS) and the Interaction Anxiousness Scale (IAS), a two-stage longitudinal follow-up study of 392 college students from three universities in Henan Province was conducted over a six-month period (October 2022 to March 2023) using a cross-lagged model to explore the correlation between rumination and social anxiety. The results of the correlation analysis showed that rumination was positively associated with social anxiety at both time points (r = 0.18,0.12, p < 0.01).

RESULTS

Cross-lagged regression analyses revealed that the predictive effect of the first measure (T1) rumination on the second measure (T2) rumination was statistically significant (β = 0.32, p < 0.001). The predictive effect of T1 social anxiety on T2 social anxiety was statistically significant (β = 0.65, p < 0.001), the predictive effect of T1 rumination on T2 social anxiety was statistically significant (β = 0.33, p < 0.001), and the prediction of T1 social anxiety on T2 rumination was statistically significant (β = 0.28, p < 0.001).

CONCLUSION

College students' rumination and social anxiety are mutually predictive of each other, and interventions by educators in either of these areas have the potential to interrupt the vicious cycle between ruminant thinking and social anxiety.

How Can We Best Assess Spatial Skills? Practical and Conceptual Challenges

Spatial thinking skills are associated with performance, persistence, and achievement in science, technology, engineering, and mathematics (STEM) school subjects. Because STEM knowledge and skills are integral to developing a well-trained workforce within and beyond STEM, spatial skills have become a major focus of cognitive, developmental, and educational research. However, these efforts are greatly hampered by the current lack of access to reliable, valid, and well-normed spatial tests. Although there are hundreds of spatial tests, they are often hard to access and use, and information about their psychometric properties is frequently lacking. Additional problems include (1) substantial disagreement about what different spatial tests measure-even two tests with similar names may measure very different constructs; (2) the inability to measure some STEM-relevant spatial skills by any existing tests; and (3) many tests only being available for specific age groups. The first part of this report delineates these problems, as documented in a series of structured and open-ended interviews and surveys with colleagues. The second part outlines a roadmap for addressing the problems. We present possibilities for developing shared testing systems that would allow researchers to test many participants through the internet. We discuss technological innovations, such as virtual reality, which could facilitate the testing of navigation and other spatial skills. Developing a bank of testing resources will empower researchers and educators to explore and support spatial thinking in their disciplines, as well as drive the development of a comprehensive and coherent theoretical understanding of spatial thinking.

Examining gender effects in autistic written language skills: A small sample exploratory study

Background and aims

Gender differences in the written language of autistic individuals are an overlooked but important area of research. We contend that the gender differences in spoken language of autistic individuals may extend to written language, mirroring the gender differences of writing in the general population and reflecting the shared dimensionality of oral and written language. Our research question was: Do autistic adolescent females demonstrate written language characteristics, across persuasive, expository, and narrative genres, that are distinct from those of autistic adolescent males and non-autistic (NA) adolescent females?

Methods

We performed a secondary, exploratory analysis on writing samples collected from 18 participants (11 autistic males, three autistic females, and four NA females) from a larger investigation of autistic adolescents' writing skills. Each participant completed three writing samples-one persuasive, one expository, and one narrative (for a total of 54 writing samples). We compared sample length (total number of words), writing productivity (words written per minute), syntactic length (mean length of T-unit in words), vocabulary diversity (type-token ratio), and macrostructure of autistic females' samples to autistic males' and NA females' samples.

Results

Based on non-parametric analyses using variable medians, autistic males, but not autistic females, wrote significantly shorter expository samples than NA females. Autistic males' writing productivity was significantly lower in the persuasive and expository genres than both autistic females and NA females. Several other comparisons of sample length, productivity, vocabulary diversity, and persuasive and narrative macrostructure yielded large effect sizes but were not statistically significant.

Conclusions

Though our small sample sizes prevent us from drawing generalizable conclusions, we observed that some gender-specific findings of the current study differ from previous findings based on a single autistic group (females and males combined). Combining data of autistic females with autistic males may cloud the distinct written language characteristics of each group.

Implications

Our findings, especially when situated in the context of relevant literature, suggest that larger-scale investigation of gender differences in written language is essential in order to more fully describe the unique characteristics of autistic females. Clinicians should be prepared to support autistic writers' needs for producing written language to meet their developmental, academic, social, and employment-related goals.

Factors associated with willingness to perform basic life support in the community setting in Yogyakarta, Indonesia

BACKGROUND

Cardiac arrest is one of the fatal medical emergencies which need to be treated immediately. Poor survival rates in the community settings are common because of limited and ineffective bystander basic life support (BLS). This study aimed to identify factors that are associated with the willingness to perform BLS in communities in Yogyakarta, Indonesia METHODS: A descriptive study was conducted with a cross-sectional design. Participants (n = 251) were enrolled from the general population consisting of teachers, security personnel, and police officers recruited through cluster random sampling. Data were gathered using both digital or printed questionnaires. Ordinal logistic regression with adjusted odds ratio (AOR) was used to analyze the association between BLS predictors and willingness to perform BLS.

RESULTS

Most participants were willing to perform BLS for all genders (55.55%). The inability to perform BLS and fear of causing harm were the main barriers to performing BLS accounting for 61.35% and 43.82%, respectively. Compared to other independent predictors, ages 40-59 were found to be the highest predictors of willingness to perform BLS (AOR:1.44) followed by experience of seeing real or simulation of the emergency case (AOR:1.38) CONCLUSIONS: More than half of the respondents were eager to perform BLS although some barriers were also found. This study provides some understanding of the predictor factors associated with BLS performance and shows respondents with some training or experience were more likely to perform BLS. The results inform policymakers to develop a strategic plan for increasing willingness to apply BLS in the community. WC:250.

Body Dissatisfaction, Cognitive Distraction, and Sexual Satisfaction in a Sample of LGB+ People: A Mediation Study Framed by Cognitive Psychology Models of Sexual Response

Introduction: Body dissatisfaction is a well-established risk factor for emotional problems and low levels of well-being indicators, such as sexual health. Cognitive models propose that dissatisfaction with one's body can cause cognitive distraction related to physical appearance during sexual activity. This may compromise sexual response, namely, sexual satisfaction in heterosexual cis women. However, this relationship has only been studied within heterosexual samples. The present study aims to test a mediation model using cognitive distraction related to body appearance during sexual activity as a mediator between body dissatisfaction and sexual satisfaction in LGB+ cis people (lesbian, gay, bisexual, and other minority sexual orientations). Methods: This cross-sectional online study comprised 165 cisgender LGB+ participants (n = 67 cis women, 40.6%; n = 98 cis men, 59.4%). Self-report questionnaires were used: the Global Body Dissatisfaction Scale, the Body Appearance Distraction Scale, and a Single-Item Measure of Sexual Satisfaction. Results: Cis women and cis men experience similar levels of body dissatisfaction, cognitive distraction with body appearance during sexual activity, and sexual satisfaction. Body appearance cognitive distraction during sexual activity mediated the relationship between body dissatisfaction and sexual satisfaction only in the men's sample. Discussion: Overall, in terms of gender and body dissatisfaction, our results reveal a reversed pattern than those found in heterosexual samples. This may be because LGB+ cis women may conform less to societal pressure, leading to less meaning given to body dissatisfaction in relation to sexuality, which may lead to more positive sexual outcomes. Likewise, LGB+ cis men present higher body dissatisfaction and experience lower sexual satisfaction, possibly due to the emphasis on physical appearance in the gay subculture. The results confirm the validity of cognitive models of sexual response.

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.

Instructors' Gestural Accuracy Affects Geology Learning in Interaction with Students' Spatial Skills

Complex and often unobservable STEM constructs and processes are represented using a variety of representations, including iconic gestures in which the body is configured or moved to resemble a referent's spatial properties or actions. Earlier researchers have suggested links between gesturing and expertise, leading some to recommend instructional gestures. Earlier research, however, has been largely correlational; furthermore, some gestures may be made with misleading positions or movements. Using the illustrative topic of strike in structural geology, we investigated the existence and impact of inaccurate instructional gestures. In Study 1, we examined videotapes of participants who had been asked to explain strikes to another person. We observed inaccurate (non-horizontal) strike gestures not only among novices (first introduced to strike during the study itself, n = 68) but also among participants who had greater expertise in geology (n = 21). In Study 2, we randomly assigned novices (N = 167) to watch video lessons in which the instructor accompanied verbal explanations of strikes with accurate, inaccurate, or no iconic gestures and tested students' learning on a strike-mapping task. Students with low spatial-perception skills showed no impact of their gestural condition on performance. Students with high spatial-perception skills showed no advantage from accurate gestures but performed significantly worse in the inaccurate-gesture condition. Findings suggest that recommendations to use gestures during instruction should include professional development programs that reduce the occurrence of inaccurate gestures.

Spanish adaptation of the Gender-Related Variables for Health Research (GVHR): Factorial Structure and Relationship with Health Variables

The aim of the present study was to conduct a preliminary study of the Stanford Gender-Related Variables for Health Research (GVHR) adapted to the Spanish population, testing its factor structure, sex factorial invariance and relationship with health variables. Participants were 438 adults between 19-73 years old (M = 31.90, SD = 12.12) who completed the GVHR and measures of health-related quality of life, psychological health, and health-risk behaviors. The confirmatory factorial analysis of the GVHR indicated an acceptable fit to the 7-factor structure as proposed for the North American population. Emotional intelligence and independence factors had low internal consistency, therefore, a five-factor model was tenable in the Spanish population. Sex scalar invariance was tenable, indicating that the factors latent means can be meaningfully compared across sex. Univariate logistic regressions indicated that women reported worse mental and physical health and more health limitations, but this effect dissipated when gender variables were considered. Caregiver and work strain stood out as the variables related to gender that predicted worse health-related quality of life, psychological health, and health-risk behaviors. In conclusion, factorial structure of the GVHR may differ from one culture to another. Additionally, the variables related to gender in the GVHR give a better account of the differences in health compared to biological sex.

Why and How to Account for Sex and Gender in Brain and Behavioral Research

Long overlooked in neuroscience research, sex and gender are increasingly included as key variables potentially impacting all levels of neurobehavioral analysis. Still, many neuroscientists do not understand the difference between the terms "sex" and "gender," the complexity and nuance of each, or how to best include them as variables in research designs. This TechSights article outlines rationales for considering the influence of sex and gender across taxa, and provides technical guidance for strengthening the rigor and reproducibility of such analyses. This guidance includes the use of appropriate statistical methods for comparing groups as well as controls for key covariates of sex (e.g., total intracranial volume) and gender (e.g., income, caregiver stress, bias). We also recommend approaches for interpreting and communicating sex- and gender-related findings about the brain, which have often been misconstrued by neuroscientists and the lay public alike.

Emphasizing Similarities Between Politically Opposed Groups and Their Influence in Perceptions of the Political Opposition: Evidence From Five Experiments

Across five experiments (four pre-registered, N = 4,431), we investigate whether emphasizing similarities between Republicans and Democrats can improve intergroup relations between the two groups. Members of both groups who were presented with evidence emphasizing similarities rather than differences in the psychological attitudes of both parties reported greater inclusion of the political opposition in the self, greater belief that common ground can be reached for major social issues, and warmer feelings toward the opposition. Inclusion of the political outgroup in the self mediated the effect of the similarities condition on additional outcomes, relating to more positive and less threatening perceptions of political opposition members. These findings held even when compared with a baseline condition with no information presented to participants. We conclude that by emphasizing the study of group similarities and by disseminating research in a way that highlights similarities, researchers could reduce intergroup hostilities in the political domain.

Sex/gender differences in cognitive abilities

Sex/gender differences in cognitive sciences are riddled by conflicting perspectives. At the center of debates are clinical, social, and political perspectives. Front and center, evolutionary and biological perspectives have often focused on 'nature' arguments, while feminist and constructivist views have often focused on 'nurture arguments regarding cognitive sex differences. In the current narrative review, we provide a comprehensive overview regarding the origins and historical advancement of these debates while providing a summary of the results in the field of sexually polymorphic cognition. In so doing, we attempt to highlight the importance of using transdisciplinary perspectives which help bridge disciplines together to provide a refined understanding the specific factors that drive sex differences a gender diversity in cognitive abilities. To summarize, biological sex (e.g., birth-assigned sex, sex hormones), socio-cultural gender (gender identity, gender roles), and sexual orientation each uniquely shape the cognitive abilities reviewed. To date, however, few studies integrate these sex and gender factors together to better understand individual differences in cognitive functioning. This has potential benefits if a broader understanding of sex and gender factors are systematically measured when researching and treating numerous conditions where cognition is altered.

Birth cohort changes in anxiety levels among primary school students in China during 1995-2019: A cross-temporal meta-analysis

To investigate birth cohort changes in anxiety levels among primary school students in China, we conducted a cross-temporal meta-analysis of 126 studies (N = 109,957) reporting the anxiety levels among primary school students in China during 1995-2019 using the Mental Health Diagnostic Test (MHT); higher MHT scores indicated higher anxiety. The results showed that: (1) The MHT scores for five types of mental health problems (social anxiety, lonely tendency, physical symptoms, terror tendency, and impulsive tendency) and the total MHT score were significantly negatively correlated with the data-collection year, indicating that the anxiety levels among primary school students in China decreased over time. (2) The MHT score for learning anxiety was significantly positively correlated with the data-collection year, indicating that the learning anxiety levels of primary school students in China increased over time. (3) The overall MHT score did not show significant gender differences, but gender-wise varying trends were observed in the types considered.

How people perceive malicious comments differently: factors influencing the perception of maliciousness in online news comments

This study proposes a comprehensive model to investigate the factors that influence the perceived maliciousness of online news comments. The study specifically examines individual factors, including demographic characteristics (e.g., gender and age), personality traits (e.g., empathy and attitudes toward online news comments), and reading-related factors (e.g., the amount of news comment reading). Contextual factors such as issue involvement, perceived peer behavior, and the presence of malicious comments in news articles are also considered. The results suggest that most of the proposed variables have a significant impact on the perceived maliciousness of online news comments, except for morality and issue involvement. The findings have important theoretical implications for research on malicious online news comments and provide practical guidelines for online news platforms on how to reduce malicious comments by visualizing them alongside other news comments.
