Heterosexual urban middle school students' (N = 1,757) stereotypes about gender typicality, intelligence, and aggression were assessed. Students (M = 12.36 years) rated Facebook-like profiles of peers who varied by gender, ethnicity, and sexual orientation. Several hypotheses about how the gender, ethnicity, and sexual orientation of target peers intersect to shape stereotypes were tested. As predicted, a peer's sexual orientation determined stereotypes of gender typicality, with gay and lesbian students viewed as most atypical. As expected, ethnicity shaped stereotypes of intelligence, with Asian American students seen as most intelligent. Gender, ethnicity, and sexual orientation independently and jointly affected stereotypes of aggression. These results demonstrate the value of an intersectional approach to the study of stereotypes. Implications for future research and practice are offered.

Species that coexist in hybrid zones sexually isolate through reproductive character displacement, a mechanism that favours divergence between species. In Drosophila, behavioural and physiological traits discourage heterospecific mating between species. Recently, social network analysis revealed flies produce strain-specific and species-specific social structures.

Background: Pregnancy within a year of childbirth has negative impacts on women and their children's health. We developed a digital health intervention (DHI) to empower women in contraceptive choices postpartum. Our pilot randomised controlled trial (RCT) aimed to establish the feasibility of a main RCT of the effects of the DHI compared with standard care on long-acting contraception use.

Individual variation in stress coping styles is widespread and consequential to health and fitness. Proactive (bold behavior, low stress reactivity, low cognitive flexibility) and reactive (shy behavior, high stress reactivity, high cognitive flexibility) coping styles are found in many species, but the developmental forces shaping them remain elusive. We examined how social influences, specifically mating interactions, shape the development of adult female coping styles with a manipulative rearing experiment using El Abra swordtails, Xiphophorus nigrensis.

A lack of diverse and representative participant samples in mental health intervention research perpetuates mental health disparities. This issue has become a salient concern in studies of psychedelic-assisted psychotherapy (PAT), which is emerging as a promising mental health intervention. This systematic review evaluates the reporting, representation, and analysis of participant sociodemographic characteristics in randomized controlled trials (RCTs) of PAT.
