Subdomains of gender-related occupational interests: do they form a cohesive bipolar M-F dimension?

Psychometric Evidence That Paraphilia Is a Natural Kind

Is the category paraphilia a natural kind? That is, do different paraphilias share anything scientifically interesting or are they classified together because they are unusual and sometimes problematic? We investigated this question systematically in 11 samples of paraphilic males (N = 4,617) and 11 samples of control males (N = 1,494). Primary data consisted of responses to the 11-item Paraphilic Interests Scale. Contrary to our initial hypothesis, the scale mean was similar for paraphilic and control samples. Using logistic regression and the same items, we derived three highly correlated measures that robustly discriminated paraphilic and control samples (ds ranging from 0.86 to 0.92). These successful measures capitalized on the unanticipated fact that some items (especially those assessing transvestism and masochistic humiliation) were positively associated with membership in paraphilic samples, while others (especially those assessing voyeurism) were negatively associated with such membership. Subsequent analyses focused on one of the measures, the Paraphilic Interests Scale Contrast (PISC). Consistent with prior findings distinguishing paraphilias and homosexual orientation, PISC was not elevated among homosexual males compared with heterosexual males among the control groups. Within four paraphilic samples, PISC was positively associated with additional paraphilic phenomena. Results provide tentative support for both the proposition that paraphilia is a natural kind and the usefulness of PISC as a measure of paraphilia.

Recalled Childhood Gender-Related Play Behaviour and Current Gender-Related Occupational Interests in University Students: Examining the Mediating Roles of Gender Compatibility, Goal Endorsement, and Occupational Stereotype Flexibility

Substantial average gender differences in childhood play behaviour and occupational interests have been well-documented. Recent research shows that childhood gender-related play behaviour longitudinally predicts gender-related occupational interests in adolescence (Kung, 2021). The first aim of the present study was to extend this recent finding by examining whether university students' recalled childhood gender-related play behaviour predicts their current gender-related occupational interests. The second aim of the present study was to investigate whether gender-related socio-cognitive processes mediate the relation between childhood play behaviour and subsequent occupational interests. University students (260 men, 542 women) completed scales assessing recalled childhood gender-related play behaviour, gender-related occupational interests, gender typicality, gender contentedness, agentic goal endorsement, communal goal endorsement, and gender-related occupational stereotype flexibility. In the present study, recalled childhood gender-related play behaviour predicted gender-related occupational interests in both men and women. In men, gender typicality and gender contentedness mediated the play-interests link. In women, gender typicality and communal goal endorsement mediated the play-interests link. The present study provides further evidence that childhood gender-related play behaviour is related to subsequent gender-related occupational interests. Although the current study has a correlational design, one interpretation of the current findings is that childhood play may influence socio-cognitive processes, such as gender compatibility and goal endorsement, which may in turn shape occupational interests.

Is there a g-factor of genderedness? Using a continuous measure of genderedness to assess sex differences in personality, values, cognitive ability, school grades, and educational track

Some of the most persistently recurring research questions concern sex differences. Despite much progress, limited research has thus far been undertaken to investigate whether there is one general construct of genderedness that runs through various domains of human individuality. In order to determine whether being gender typical in one way goes together with being gender typical also in other ways, we investigated whether 16-year-old Finnish girls and boys ( N = 4106) differ in their personality, values, cognitive abilities, academic achievement, and educational track. To do this, we updated the prediction-focused gender diagnosticity approach by methods of cross-validation for more accurate estimation. The preregistered analysis shows that sex differences vary across domains ( Ds = 0.15–1.48), that fine-grained measures, such as grade profiles, can be accurate in predicting sex (77.5%), whereas some summary indices, such as general cognitive ability, do not perform above-chance (52.4%), and that the genderedness correlations, despite all being positive, are too weak (average partial correlation, r´ = .09, range .03–.34) to support a general factor of genderedness. Our more exploratory analyses show that more focus on gender typicality could offer important insights into the role of gender in shaping people’s lives.

Occupational Preferences and Recalled Childhood Sex-Atypical Behavior among Istmo Zapotec Men, Women, and Muxes

Research has found that both cisgender and transgender androphilic males (i.e., males sexually attracted to and aroused by other adult males) have female-typical occupational preferences when compared with gynephilic males (i.e., males sexually attracted to and aroused by adult females). Moreover, whereas cisgender androphilic males' occupational preferences tend to be intermediate between those of gynephilic men and androphilic women, transgender androphilic males tend to have occupational preferences that are more similar to androphilic women. No study has directly compared both types of androphilic males within the same culture. The present study investigated occupational preference and its relation to childhood sex-atypical behavior (CSAB), among gynephilic men (n = 208), androphilic women (n = 138), and cisgender (n = 132) and transgender (n = 129) androphilic males from the Istmo region of Oaxaca, Mexico, where androphilic males are recognized as third gender, muxes. The study found large sex differences in occupational preferences (d = 2.80). Furthermore, both cisgender muxe nguiiu (d = 2.36) and transgender muxe gunaa (d = 3.44) reported having more sex-atypical occupational preferences compared with men. However, muxe gunaa reported higher female-typical occupational preferences than women (d = 0.59) and muxe nguiiu (d = 0.57), whereas muxe nguiiu and women did not differ (d = 0.08). These findings are consistent with the conclusion that sex-atypical occupational preferences are a cross-culturally universal aspect of male androphilia. Finally, CSAB was associated with sex-atypical occupational preferences among all participants. These findings suggest that a developmental continuity exists between childhood and adulthood sex-atypicality.

S. Sex Determination and Sex Differentiation

Sex determination is arguably the most defining moment of our lives, the point where we inherit X or Y chromosome from our father. This initiates a cascade of events that sets in a train of morphological changes, genetic regulations and molecular mechanisms. Following this, our fate is further sealed during sex differentiation and gonadal development owing to the action of sex-specific gonadal hormones. Therefore, the profoundly divergent journeys of male and female lives are decided just by the toss of a genetic coin. The existence of a third gender is also an undeniable aspect of our society. The understanding of the functioning and genetic regulation of the complex process of sexual determination and differentiation is pivotal in comprehension of the basis of human life. Any deviation from the usual mechanisms in the critical stages of development leads to disorders of sexual differentiation leading to sexual ambiguity among individuals. This review discusses the mechanisms that contribute to female and male sex determination and gonadal development, in an attempt to understand the basics of human sex.

Preschool Gender-Typed Play Behavior Predicts Adolescent Gender-Typed Occupational Interests: A 10-Year Longitudinal Study

There are significant gender differences in both play behavior and occupational interests. Play has been regarded as an important medium for development of skills and personal characteristics. Play may also influence subsequent preferences through social and cognitive processes involved in gender development. The present study investigated the association between gender-typed play behavior in early childhood and gender-typed occupational interests in early adolescence. Participants were drawn from a British longitudinal population study, the Avon Longitudinal Study of Parents and Children. Participants were recruited based on their parent-reported gender-typed play behavior assessed at age 3.5 years. There were 66 masculine boys and 61 masculine girls, 82 feminine boys and 69 feminine girls, and 55 randomly selected control boys and 67 randomly selected control girls. At age 13 years, the participants were administered a questionnaire assessing their interest in gender-typed occupations. It was found that masculine children showed significantly more interest in male-typical occupations than did control or feminine children. Compared with control children, feminine children had marginally significantly lower interest in male-typical jobs. Masculine children also had significantly lower interest in female-typical jobs than did control or feminine children. The associations were not moderated by gender and were observed after taking into account sociodemographic background, parental occupations, and academic performance. The degree of gender-typed play shown by preschoolers can predict their occupational interests 10 years later following transition into adolescence. Childhood gender-typed play has occupational implications that transcend developmental stages.

Are Interest Assessments Propagating Gender Differences in Occupations?

The current study focused on the effect of assessment methods on estimates of gender differences in interests across Holland’s themes. College students (121 women, 76 men) rated their interests in Holland-based activities and occupations using Likert-type scales, and they also completed a card sorting assessment of Holland interests using occupation-based items. Gender differences were consistently observed for realistic and social interests with the magnitude of the observed gender differences varying by measure type. A Gender × Measure interaction accounted for 33% of the variance observed in interest scores: Occupation-based scales produced larger differences than activity-based scales, and the card sorting assessment produced larger gender differences than the Likert-type rating scales. Therefore, the choice of interest measure used in career counseling may influence the extent to which gender affects the career decision-making process, which may be particularly important when exploring nontraditional career choices for women and men.

A general theory of sexual differentiation

A general theory of mammalian sexual differentiation is proposed. All biological sex differences are the result of the inequality in effects of the sex chromosomes, which are the only factors that differ in XX vs. XY zygotes. This inequality leads to male-specific effects of the Y chromosome, including expression of the testis-determining gene Sry that causes differentiation of testes. Thus, Sry sets up lifelong sex differences in effects of gonadal hormones. Y genes also act outside of the gonads to cause male-specific effects. Differences in the number of X chromosomes between XX and XY cells cause sex differences in expression (1) of Xist, (2) of X genes that escape inactivation, and (3) of parentally imprinted X genes. Sex differences in phenotype are ultimately the result of multiple, independent sex-biasing factors, hormonal and sex chromosomal. These factors act in parallel and in combination to induce sex differences. They also can offset each other to reduce sex differences. Other mechanisms, operating at the level of populations, cause groups of males to differ on average from groups of females. The theory frames questions for further study, and directs attention to inherent sex-biasing factors that operate in many tissues to cause sex differences, and to cause sex-biased protection from disease. © 2016 Wiley Periodicals, Inc.

The Sexual Orientation and Gender Presentation of Hijra, Kothi, and Panthi in Mumbai, India

Cultural categories related to sexuality and gender vary considerably cross-culturally. While Western cultures categorize people primarily in terms of sexual attractions (i.e., gay, straight, bisexual), many cultures distinguish between groups based on additional issues such as gender role presentation and position preference in anal sex (i.e., insertive/receptive). The current study gathered data on three categories of natal males in Mumbai, India-hijra, kothi, and panthi (N = 93). Hijra are androphilic (sexually attracted to adult men), typically sexually receptive, transgender, sometimes castrated, and live in fictive kinship networks that are hierarchically organized. Kothi are also androphilic, typically sexual receptive and relatively feminine but less so than hijra; unlike hijra, kothi are never castrated. Hijra and kothi were understood by some participants to be mutually compatible, and so three groups were identified-those endorsing hijra only (n = 11), kothi only (n = 22), and both hijra and kothi (n = 22). Panthi (n = 38) are the masculine insertive partners of hijra and kothi. Measures employed were self-report and viewing time measures of sexual attraction, sexual behavior and position preference, self-described masculinity/femininity, recalled childhood gender atypicality, gendered occupational preferences, and gender presentation milestones (i.e., wearing female clothes, castration). All hijra and kothi groups were found to be exclusively androphilic in viewing time and self-reported sexual attractions, and to be gender-atypical on all measures. Panthi were found to be relatively male-typical and to have a bisexual pattern of viewing time and self-reported sexual attractions. Kothi were found to be less extreme in their female typicality and to report less female gender presentation milestones than hijra or hijra/kothi. Most hijra and hijra/kothi and all kothi said that they were not castrated. Contrary to the manner in which they are socially defined, a third of panthi report having been receptive in anal sex, and a third of all hijra and kothi groups report having been insertive at some time.

On the Relationship Between Domain-Specific Creative Achievement and Sexual Orientation in Swedish Twins

Despite the commonly held belief that homosexual males and females are more creative compared to heterosexuals, empirical studies on homosexuality and its relationship to creativity have been sparse, often with questionable methodology and very small sample sizes, reporting mixed findings. No study till date has explored the associations described above in a large population-based and genetically informative sample. Here, we examined such potential associations between sexual orientation and creative achievement in several different domains (music, writing, dance, visual arts, science, invention, and theater) using a large cohort of 4494 Swedish twins (of which 7.5 % were not exclusively heterosexual). Data were analyzed for the sexes separately as well as pooled. Results showed significant associations between sexual orientation and two of the creative domains-theater and writing-with non-heterosexuals being more creative in these domains. In all other domains, no significant differences were found between the non-heterosexual and heterosexual groups. Findings from co-twin control analyses suggested that the significant associations may not be causal in nature (i.e., homosexual orientation leads to higher creativity) but due to shared liability. However, we lacked power to differentiate between shared genetic and shared environmental influences. Results and potential implications are discussed critically.

Putative Androgen Exposure and Sexual Orientation: Cross-Cultural Evidence Suggesting a Modified Neurohormonal Theory

INTRODUCTION

According to neurohormonal theory, prenatal androgens are key determinants of sexual orientation. As a reputed marker for prenatal androgens, the 2D:4D finger length ratio has been used in more than a dozen studies to test the hypothesis that prenatal androgens influence sexual orientation. Findings have been very inconsistent.

AIM

The present study sought to retest the hypothesis that 2D:4D and sexual orientation are related is a manner consistent with neurohormonal theory.

METHODS

A 2D:4D measure (of the right hand) along with four additional somatic markers of androgen exposure (height, physical strength, muscularity, and athletic ability) with samples of college students in Malaysia (N = 2,058) and the United States (N = 2,511). The five androgen measures were factor analyzed, resulting in a two-factor solution: Factor 1 consisted of strength, muscularity, and athletic ability (the muscular coordination factor), and Factor 2 was comprised of the r2D:4D and adult height (the bone growth factor).

MAIN OUTCOME MEASURES

Sexual orientation was measured by asking each respondent the extent to which they were sexually attracted to males and the extent to which they were sexually attracted to females, both on 11-point scales.

RESULTS

When the countries and sexes were analyzed separately, neither the r2D:4D measure nor Factor 2 correlated with sexual orientation to significant degrees. Instead, it was the muscular coordination factor that correlated the best. Support was found for the hypothesis that prenatal androgens influence sexual orientation, but the nature of these influences was more complex than neurohormonal theory predicted.

CONCLUSION

A modified theory is needed and presented to accommodate the results from this study.

Gender and gender role differences in self- and other-estimates of multiple intelligences

This study examined participant gender and gender role differences in estimates of multiple intelligences for self, partner, and various hypothetical, stereotypical, and counter-stereotypical target persons. A general population sample of 261 British participants completed one of four questionnaires that required them to estimate their own and others’ multiple intelligences and personality traits. Males estimated their general IQ slightly, but mathematic IQ significantly higher than females, who rated their social and emotional intelligence higher than males. Masculine individuals awarded themselves somewhat higher verbal and practical IQ scores than did female participants. Both participant gender and gender role differences in IQ estimates were found, with gender effects stronger in cognitive and gender role than in “personal” ability estimates. There was a significant effect of gender role on hypothetical persons’ intelligence evaluations, with masculine targets receiving significantly higher intelligence estimates compared to feminine targets. More intelligent hypothetical figures were judged as more masculine and less feminine than less intelligent ones.

Feeding the pipeline: Gender, occupational plans, and college major selection

In this article, we analyze gender differences in college major selection for respondents to the Education Longitudinal Study (2002-2006), focusing on educational pathways through college that lead to science, engineering, or doctoral-track medicine occupations and to non-doctoral track clinical and health sciences occupations. We show that gender differences in college major selection remain substantial, even for a cohort in which rates of enrollment in postsecondary education are more than ten percent higher for young women than for young men. Consistent with other recent research, we demonstrate that neither gender differences in work-family goals nor in academic preparation explain a substantial portion of these differences. However, the occupational plans of high school seniors are strong predictors of initial college major selection, a finding that is revealed only when occupational plans are measured with sufficient detail, here by using the verbatim responses of students. We also find that the association between occupational plans and college major selection is not attributable to work-family orientation or academic preparation. Finally, we find gender differences in the associations between occupational plans and college major selection that are consistent with prior research on STEM attrition, as well as with the claim that attrition also affects the selection of majors that are gateways into doctoral-track medicine. We discuss the implications of the predictive power of occupational plans formed in adolescence for understanding sex segregation and for policies intended to create a gender-balanced STEM and doctoral-level medical workforce.

Gender nonconformity, sexual orientation, and psychological well-being

Both a same-sex sexual orientation and gender nonconformity have been linked with poorer well-being; however, sexual orientation and gender nonconformity are also correlated. It is, therefore, critical to investigate their independent contributions to well-being. Based on survey responses of 230 female and 245 male high school seniors, the present study is one of the first to provide empirical data on this topic. Both childhood and adolescent gender nonconformity were negatively related to well-being. In the same analyses, neither sexual orientation nor biological sex was a significant predictor of well-being. These results suggest that gender-atypical traits may be more relevant for psychological health than a same-sex sexual orientation. Both environmental and biological influences may account for these findings.

Relação entre gênero e orientação sexual a partir da perspectiva evolucionista

Este estudo trata da relação entre gênero e orientação sexual a partir da perspectiva interacionista da Psicologia Evolucionista e da análise de diferentes elementos da sexualidade humana. Procurou-se discutir a literatura existente sobre os conceitos de gênero e de orientação sexual, com base nos quatro porquês da Etologia. Propõe-se a existência de múltiplas origens para a orientação sexual, sendo uma delas relacionada aos padrões típicos de gênero e à identidade de gênero. Isso levaria à identificação com indivíduos do mesmo sexo ou do sexo oposto e, consequentemente, à atração pelo grupo diferente daquele com o qual se desenvolveu a identificação. Essa perspectiva integra pré-disposições biológicas à análise de influências culturais, compreendendo, como complementares, vertentes teóricas usualmente tidas como contraditórias.

Compreendendo as diferenças de gênero a partir de interações livres no contexto escolar

Para a Psicologia Evolucionista as diferenças de gênero existentes nas brincadeiras resultam de influências culturais que interagem com uma pré-disposição selecionada na espécie. Objetivou-se investigar se tais diferenças seriam compatíveis com dimorfismo sexual descrito na literatura da área. Setenta e três alunos entre seis e sete anos de uma escola particular foram filmados em quatro sessões de 30 minutos de recreio. Contabilizou-se a freqüência dos comportamentos e os pares com que ocorriam. Posteriormente, 21 crianças foram entrevistadas sobre suas brincadeiras prediletas e suas classificações de brincadeiras segundo o gênero. Pôde-se observar que ambos os sexos participam de atividades similares, mas em interações intra-sexuais. Além disso, observaram-se diferenças topográficas na forma de brincar, de acordo com o sexo. Nas entrevistas, como previa a literatura, foram registradas diferenças entre o relatado e o observado, indicando maior influência cultural sobre o conteúdo relatado.

Male and Female College Students’ College Majors

The first purpose was to determine if overall gender differences in basic confidence as measured by the Expanded Skills Confidence Inventory (ESCI) and basic interests as measured by the 2005 Strong Interest Inventory (SII) would be present within eight college major families. As expected, anticipated overall gender differences in confidence and interests concerning realistic and conventional activities were visible within the major families as well. The second purpose was to determine whether basic domains of confidence and interests would differentially discriminate among the eight major families differentially for 171 male and 176 female college students. When confidence and interests were examined separately, the set of confidence predictors and the set of interest predictors significantly differentiated among college majors for both men and women. When confidence and interests were combined together as two sets of predictors, the hit rate was a significant improvement over the hit rate for the confidence set of predictors alone for both women and men. As anticipated, group centroids and structure matrices varied across men and women.

Gender-Related Occupational Interests Do Not Define a Masculinity-Femininity Factor

Abstract. The possible existence of a broad factor of masculine versus feminine (M-F) occupational interests was tested. Data from Lippa (2005) were reanalyzed using common factor analysis and omitting redundant composite variables. The first unrotated factor, as obtained in male-only and female-only samples, was very small and showed weak loadings for most interest scales. Moreover, strong negative correlations between overall “masculine” and “feminine” interests were shown to be a statistical artifact. Second, analyses of new data on the Campbell Interest and Skills Survey indicated that, when gender differences were controlled, gender-related scales showed only very modest loadings on a potential M-F interests factor; in addition, several scales were mutually uncorrelated, a result that was not attributable to the influence of any second factor. Results undermine the hypothesis of a broad factor of M-F occupational interests.
