This study aims to identify early childhood sociability trajectories and examine their longitudinal associations with behavior problems. Using a population-based data set presented by the Panel Study on Korean Children, sociability trajectories from age 2 to age 4 were identified by latent class growth analysis. Associations between sociability…

Objective: Executive Function (EF) is thought to be a core component of various cognitive processes. Two common ways to measure EF are through report-based measures that assess EF by collecting informant(s) reports on children's behaviors, and performance-based measures that assess EF through the completion of a task related to EF dimension(s).…

Bias influencing teachers' classroom management is increasingly clear, but the circumstances that influence the likelihood of relying on those biases are less understood. This study employed Classification and Regression Tree (CART) analysis, resulting in four models examining how teachers' appraisals of first-grade students' externalizing problem…

This study focused on associations between children's socioemotional development (prosocial behaviour, internalizing and externalizing problems) and parenting styles (affection, behavioural control, and psychological control), and the moderating role of children's social withdrawal (as a temperamental characteristic) in these associations.…

This study investigated the utility of including teacher-reported callous-unemotional (CU) behaviors in the assessment of disruptive behaviors in school-based research. Participants included 138 first- and second-grade children (68% male; 76% eligible for free or reduced-price lunch; 61% Black, 9% Latinx, 23% White, and 7% multiracial) who…

Deficits in language skills are a risk factor for later aggressive behaviour. However, previous research has mainly addressed clinical or high-risk samples and relations between language and aggressive behaviour in preschoolers and children in primary school. Based on a German longitudinal project with N = 547 typically developing children, the…

Using data from 832 kindergarten and first grade primary teachers and 662 of their students, the current study investigated teachers' use of behavioral and instructional classroom practices and whether these strategies moderated associations between teachers' expressions of positive and negative classroom emotion and students' social-emotional and…

The present study examined the academic antecedents of declining peer social status. Participants included 545 (311 boys, 234 girls) Finnish students followed from the 1st through the 4th grade (ages 6-8 at outset). Each year, teachers completed assessments of academic task avoidance and students completed standardized measures of reading and math…

Leading research argues the distinct importance of earliest detection of childhood behavior problems and the value of discovering subsequent change patterns as children transition through the early education years. This study examined the relative contributions of earliest assessments of children's problem behaviors as compared to the changes in…

To investigate the antecedents of children's trait- and state-level peer competence, this study used a random-intercepts model to separately explore the influences of early stable predictors (i.e. temperament and attachment) and dynamic environmental factors (i.e. family and school) on peer competence. The study sample included children in the…

Social-behavioral functioning during early childhood is associated with children's academic and social success concurrently and over time. This study explored how concurrent, year-to-year, and sustained parent--teacher and student--teacher relationships predicted children's social skills and problem behaviors across the preschool to Grade 1…

This study examined associations of aggressive and prosocial behaviors with perceived support and negativity in children's best friendships before and after the transition to secondary school (N= 1,073; 49.2% girls). Teachers rated children's aggressive and prosocial behaviors in grades 1, 3, 4, and 6 of primary school. In grade 6 and the first 2…

This study sought to elucidate the contributions of inferior executive function and social competence to the development of internalizing and externalizing problems in primary school. Children (N = 1,115), on average 5.36 years old in first grade, were followed across primary school with measures of multi-method and multi-informant. Results of…

Self-regulation is a critical component of school readiness and success. Practices for supporting self-regulation may be advanced by a better understanding of factors characterizing children at risk for challenges and contextual mechanisms associated with desirable developmental trajectories. The current study leverages a large national data set…
