Longitudinal research on language abilities and social functioning in young children suggests that gains in one domain affect gains in the other. However, few studies have examined inter-relations of language and social functioning jointly among young children diagnosed with autism spectrum disorder (ASD). Pre-verbal toddlers with ASD are a group…

The effect associated with the presence of seizures in 2 to 5-year-old autistic children was investigated in the largest and the longest observational study to-date. Parents assessed the development of 8461 children quarterly for three years on five orthogonal subscales: combinatorial receptive language, expressive language, sociability, sensory…

Guided by the ecological model of civic development, this study examined the extent to which the growth in children's self-control during middle childhood predicted their civic engagement at age 26 directly and indirectly via their prosociality at age 15. We used data from 1,042 children (50% female, 77% White) in the NICHD Study of Early Child…

The positive links between children's theory of mind (ToM), emotion understanding, and positive peer relationships are well established. However, the existing literature lacks comprehensive studies investigating the longitudinal interplay between these components in preschool-aged children. This study aimed to fill this gap by examining the…

In this article, we examined young Finnish children's social relationships, characteristics of their parents' social networks and the role of parental networks in children's peer relationships. We drew on the data collected from a Finnish longitudinal study known as Steps to the Healthy Development and Well-Being of Children. The data from two…

Social skills are dynamic developmental constructs typically measured using assessments developed via cross-sectional methods. The measurement model of derivatives (MMOD), a factor analytic approach targeting individual growth trajectories, was used to evaluate the longitudinal factor structure of the Social Skills Improvement System--Rating…

Preschool teachers' perceptions about relationships with students (teacher-child relationships [TCRs]) predict children's subsequent social competence (SC) and academic progress. Why this is so remains unclear. Do TCRs shape children's development, or do child attributes influence both TCRs and subsequent development? Relations between TCRs and…

Girls, more than boys, experience a decrease in the severity of autism symptoms during childhood. It is unclear, however, which specific autistic behaviors change more for girls than for boys. Trajectories of autism symptoms were evaluated using the Autism Diagnostic Observation Schedule-calibrated severity scores (ADOS-CSS). Change in the…

Research Findings: Immigrant families who represent a growing share of the early schooling population face unique challenges related to involvement in their children's education. This study examined whether and to what extent home-based parent involvement and parental warmth are associated with the socio-emotional and academic outcomes of children…

Despite widespread interest in the construct of executive functioning (EF), we currently lack definitive evidence regarding the best measurement model for representing the construct in substantive analyses. The most common practice is to represent EF ability as a reflective latent variable, with child performance on individual EF tasks as observed…

This document describes plans for the analysis of the Mother and Infant Home Visiting Program Evaluation (MIHOPE) follow-up data collected when participating children were in kindergarten or first grade. The overarching goal of MIHOPE is to provide information about whether families and children benefit from Maternal, Infant, and Early Childhood…

Children's early skills are strong predictors of later learning outcomes. Research aiming to disentangle the causal effects of early skills from unmeasured, stable characteristics related to learning throughout development demonstrates that unmeasured confounders explain a large portion of the effects of early skills previously identified. To…

Background/Context: School readiness refers to the foundational skills and behaviors children leverage as they begin kindergarten, including a combination of early academics, executive function (EF), and social-emotional competencies. In both high-income and low- and middle-income countries, these early skills collectively enable children to…

Continuity of pre-k and kindergarten classroom experiences is a key area of interest for early childhood researchers interested in supporting public pre-k children's development over time. To advance the empirical evidence on this topic, this study examined whether differences in classroom experiences as children transition from pre-k to…

The current research aims at constructing a developmentally sensitive mindreading scale (i.e., a battery of tasks measuring different aspects of mindreading ability in children from 1 to 3.5 years of age). Over 300 Polish children were tested at six-month intervals with 48 different tasks designed to measure mindreading ability (for a total of six…
