Research Findings: We tested whether a universal classroom peer pairing intervention -- "Buddy Up" -- would strengthen dyadic peer interactions among preschoolers (N = 140; M[subscript age] = 56.49 months; 53.6% boys; 77.9% Latinx). The "Buddy Up" intervention was informed by Intergroup Contact Theory, which specifies the…

Most US students attend coeducational classes, but to what extent do students feel integrated into the entire classroom of their peers, especially with other-gender (OG) peers? The major goal of this study was to investigate how variations in gender integration (GI), measured by students' expectancies about inclusion, efficacy, and social costs of…

The purpose of this article is to highlight the important role that gender plays in organizing and affecting the quality of the classroom climate. We review research showing how students' peer relationships tend to be segregated by gender and discuss the consequences of children spending much of their time almost exclusively with same-gender…

Despite the fact that most boys and girls are in classrooms together, there is considerable variation in the degree to which their classrooms reflect gender integration (GI). In some classrooms, boys' and girls' relationships with each other are generally positive and harmonious. However, in other classes, students tend to only work with…

The goals of this study were to investigate whether young children attending Head Start (N = 292; M[subscript age] = 4.3 years) selected peers based on their preschool competency and whether children's levels of preschool competency were influenced by their peers' levels of preschool competency. Children's peer interaction partners were…

Preschoolers' (60 boys and 64 girls, "M" age = 50.73 months) affiliations with prosocial peers were observed in naturally occurring interactions and then examined in relation to positive and negative emotionality within their peer interactions one semester later. Greater affiliation with prosocial peers in the fall was related to enhanced positive…

A stochastic actor-based model was used to investigate the origins of sex segregation by examining how similarity in sex of peers and time spent in gender-typed activities affected affiliation network selection and how peers influenced children's ("N" = 292; "M"[subscript age] = 4.3 years) activity involvement. Gender had…

Transactional relations between children's positive social interaction skills, school engagement, and academic achievement were examined using a longitudinal panel model across the transition from preschool to first grade. Participants were Head Start children (N = 241; 49% girls, M age = 53 months, range 45-60); 78% were Mexican/Mexican-American;…

Preschoolers' (M[subscript age]=48.7 months) social breadth (the number of peer children interact with and the frequency of these interactions) and the relations between breadth and externalizing behaviors were examined using the Q-connectivity method. After considering age, sex, and classroom effects on social breadth, children's externalizing…

How, when, and under what conditions do peer interactions contribute to variations in developmental trajectories along dimensions that are important to children's well-being? These compelling and fundamental questions have piqued the interest of developmental scientists and led to studies of the ways in which peers socialize and affect such…

We examined the role of the teacher-child relationship quality (close, dependent, and conflictive) on preschoolers' (N=95) academic readiness for kindergarten, and we tested children's prosocial and aggressive behavior and peer group exclusion as mediators of this relation. A unique feature of this study is the ethnically and socio-economically…

Examined how preschoolers coped with anger toward well-liked and not-well-liked peers. Found no differences in the intensity of anger provocations by well-liked and not-well-liked provocateurs, but responses to provocations by well-liked peers were more controlled than responses provoked by peers who were not well liked.

Based on observation of 94 kindergartners and preschoolers for 3 months, this study examined changes in preschoolers' tendencies to play alone as a function of dispositional negative emotional intensity (DNEI) and changes in expressed negative emotions. Findings indicated higher emotional intensity, increased solitary play, and decreased…
