For 14 days three times per day (6072 observations), adolescents (N=207, M[subscript age]=15.45 years) reported their digital (i.e., video chatting, texting, social media, and phone calling) communication with peers and their social connectedness. Controlling for in-person interactions, adolescents felt more connected in hours when they had…

How gender diversity is exhibited varies: some individuals feel similar to the other gender; others experience little similarity to either gender, and some feel similar to both genders. For children, do these variations relate to differing relationships with peers? The goal was to assess whether a community sample of children (884, Mage = 9.04, SD…

Close peer relationships are critical to children's and adolescents' healthy development and well-being, yet youth sometimes struggle to make friends. The present work tested whether an online version of the Fast Friends procedure could engender closeness among 9- to 13-year-old youth. Participant dyads (N = 131), matched in age and gender, were…

Peer interaction offers critical learning opportunities for preschool students, yet exposure to peers of different skill levels varies within and across classrooms. We explore two ways peers may affect learning: differences in who children play with in a classroom and differences in student composition across classrooms. We find that playing with…

Students' academic engagement is greatly informed by a classroom's social climate. However, more research is needed regarding how specific peer behavior, especially prosocial behavior, come to shape academic engagement. The present study investigated whether students' perceptions about their classmates' prosocial behavior were associated with…

Gender-Sexuality Alliances (GSAs) are school clubs for LGBTQ+ youth and peer allies to support one another. This eight-week weekly diary study considered whether a youth's positive and negative affect during a given week could be predicted by experiences in their most recently attended GSA meeting. Ninety-nine GSA members (M[subscript age] =…

New technologies that combine digital sensors with automated processing algorithms are now being deployed to study preschool classrooms. This article provides an overview of these new sensing technologies, focusing on automated speaker classification, the analysis of children's and teachers' speech, and the detection and analysis of their…

This study used a convergent mixed methods design to examine environmental and curricular influences on peer relationships and support for young women with disabilities within a clustered, randomized controlled trial of a gender-specific, disability-focused intervention, Paths 2 the Future (P2F). Pre- and post-intervention surveys of perceptions…

The purpose of this study was to evaluate Peer Group Connection-Middle School, a cross-age peer mentor program designed to enhance student retention and achievement during the transition from elementary to middle school. We present findings from an individual-level randomized controlled trial that included 1,902 sixth-grade students across three…

Workers learn on the job from both repetition and peers. Less understood is how specific types of experience and peer characteristics affect on-the-job learning. This likely differs by context (e.g., occupation, tasks, or roles). Absent such knowledge, it is unclear how to optimally assign workers to tasks and peers. We examine on-the-job learning…

Gender-Sexuality Alliances (GSAs) and inclusive school policies and practices that affirm youth with minoritized sexual orientations or gender identities (e.g., lesbian, gay, bisexual, transgender, queer youth; LGBTQ+ youth) are two sources of support for LGBTQ+ youth that could promote school belonging. The current study tested a three-level…

Adolescents with elevated social anxiety commonly experience peer-related impairments--particularly with same-age, unfamiliar peers--stemming from their "avoidant behaviors." Yet, peer-related impairments are not unique to social anxiety. For example, adolescents who experience social anxiety may also experience symptoms of attention…

Accurately assessing youth mental health involves obtaining reports from multiple informants who typically display low levels of correspondence. This low correspondence may reflect "situational specificity." That is, youth vary as to where they display mental health concerns and informants vary as to where and from what perspective they…

The present study examined the relations between two aspects of peer experiences in preschool classrooms and children's math and literacy development during kindergarten transition. Based on the theoretical framework of classroom ecology model, peer experiences were represented by classroom social network and teachers' grouping preferences. The…

Literature has highlighted that social relationships at school are essential to school success, yet few studies have examined this construct from parents' perspectives. Even less research has explored perceptions of social relationships in the school among parents whose children are bullying victims and potential racial-ethnic differences in the…
