While research on the prevalence of co-occurring autism spectrum conditions (ASC) and trans gender modality (TGM) is available, less is known about the underlying mechanism of this association. Insight is needed to improve treatment of trans autistic people. This review provides an overview of theories on the ASC-TGM link and the available…

Which domain-specific self-evaluations are most central to children's global self-worth? And does this differ between countries with different levels of collectivism-individualism? We conducted a preregistered cross-cultural meta-analysis to address these questions. We included 141 independent samples (21 countries/regions, 584 cross-sectional…

The current review identified 11 single-case design (SCD) and 14 group-design evaluations of naturalistic behavioral interventions targeting prelinguistic social communication in young children with autism spectrum disorder (ASD). Three SCD studies and eight group design studies utilized methodologically rigorous designs and demonstrated a…

Just over ten years ago, Block (2007, p. 2) called the increasing attention that second language researchers-and social scientists at large-were giving to the construct of "identity" an "obsession." Since then, the identities of those who use, learn or study a language have been investigated in greater detail (e.g., Benson,…

In part because of the ubiquity of attachments in humans, determining when aberrant behavior is best explained as an attachment disorder as opposed to insecure attachment has led to some confusion. In…

This meta-analytic review of 42 studies covering 8,009 participants (ages 4-20) examines the relation of moral emotion attributions to prosocial and antisocial behavior. A significant association is found between moral emotion attributions and prosocial and antisocial behaviors ("d" = 0.26, 95% CI [0.15, 0.38]; "d" = 0.39, 95%…

It (a) assesses prevalence of positive, neutral, and negative attitudes about childlessness and (b) identifies the correlates of different attitudes in the population. About…

In this article the authors review research on highly stressful environments that are known to support the development and display of aggressive behavior in childhood, adolescence, and beyond. They also examine some of the mechanisms through which such stressful environments may influence adolescents' aggressive behavior. The review concentrates…

Small classes in the elementary grades have been shown to boost students' academic performance. However, researchers continue to seek a consistent, integrated explanation of "why" small classes have positive effects. This article forwards the hypothesis that when class sizes are reduced, major changes occur in students' engagement in the…
