Prejudice and discrimination toward gender non-conforming individuals is prevalent and extreme in today’s society. This prejudice can manifest in social exclusion, bullying, and victimization, or physical and sexual assault, and can result in negative social, psychological, academic, and physical health outcomes (e.g., depression, anxiety, suicidality). Thus, it is important to understand the perpetrators of gender expression-based aggression and discrimination. In two studies, I addressed how and why people experience prejudice toward gender non-conforming individuals. Using an affordance management theoretical framework, Study 1 identified threats young adults perceived from gender non-conforming peers. There were differences in perceived threats to personal freedoms, social coordination, and values for gender conforming and non-conforming peers, and these perceptions differed by the political ideology of the perceiver. Study 2 explored children’s threat perceptions associated with gender non-conformity. Children perceived threats to social coordination from gender non-conforming peers but not threats to moral values. Results from both studies supported the use of this theoretical framework for studying prejudice toward gender non-conformity. Together, these studies provide unique information about adults’ and children’s reasons for prejudice toward gender non-conforming peers.

The goal of this study was to explore the multidimensionality of gender typicality and its relation to preadolescents’ psychological adjustment. With a sample of 378 6th grade students (52% male; M age = 11.44, SD = .56; 48% White), I examined how four specific dimensions of gender typicality (behavior, appearance, activities, and peer preference) predict children’s global sense of typicality; whether children’s global sense of gender typicality, behavior, appearance, activities, and peer preference are differentially predictive of self-esteem, social preference, and relationship efficacy; and whether examining typicality of the other gender is important to add to own-gender typicality. Regression analyses indicated that all four specific typicality dimensions contributed to preadolescents’ overall sense of own- and other-gender typicality (except appearance for own-gender typicality). Generally, all domains of gender typicality were related to the four adjustment outcomes. Own-gender typicality related more strongly to self-esteem, social preference, and own-gender relationship efficacy than did other-gender typicality; other-gender typicality was more strongly related to other-gender relationship efficacy. Relations between typicality and adjustment were stronger for gender-based relationship efficacy than for self-esteem or social preference. Although some differences existed, relations between typicality and adjustment were generally similar across typicality domains. Results implicate the need to measure other-gender typicality in addition to own-gender typicality. Additional contributions and suggestions for future research are discussed.
