Longitudinal study of associations between family-level emotion socialization and adolescent adjustment is limited. When American children (53.5% girls) were in second grade (N = 213; M[subscript age] = 7.98; data collected 2002-2003), mothers and fathers (79.8% of mothers and 74.2% of fathers were White) reported on their reactions to children's…

This study examines associations between enrollment in high-quality PreK and growth in children's (N = 422; M[subscript age] = 5.63 years; 47% female; 15% Asian, 19% Black, 30% White, 31% Hispanic; 5% other or mixed race) academic, executive functioning, and social-emotional skills across kindergarten (2017-2018) and first grade (2018-2019).…

This longitudinal study modeled children's complex executive function (EF) development using the Groton Maze Learning Task (GMLT). Using a cohort-sequential design, 147 children (61 males, 5.5-11 years) were recruited from six multicultural primary schools in Melbourne and Perth, Australia. Race/ethnicity data were not available. Children were…

This study provides empirical benchmarks that quantify typical changes in students' reports of social and emotional skills in a large, diverse sample. Data come from six cohorts of students (N = 361,815; 6% Asian, 8% Black, 68% White, 75% Latinx, 50% Female) who responded to the CORE survey from 2015 to 2018 and help quantify typical…

According to the failure model (Patterson & Capaldi, 1990), peer rejection is the intermediary link between problem behaviors and internalizing symptoms. The present study tested the model with 464 monozygotic and same-sex dizygotic twin pairs (234 female, 230 male dyads). Teacher-reported reactive aggression and internalizing symptoms, and…

We examined the relation between socioeconomic status (SES), vocabulary, and reading in middle childhood, during the transition from primary (elementary) to secondary (high) school. Children (N = 279, 163 girls) completed assessments of everyday and curriculum-related vocabulary, (non)word reading, and reading comprehension at five timepoints from…

Based on investment theories and guided by Mussel's (2013) intellect model, the present study investigated reciprocal relations over 1 year (2021-2022) between investment traits (need for cognition, achievement motives, epistemic curiosity) and fluid and crystallized cognitive abilities in 565 German elementary school children (298 girls;…

Understanding how early reading and mathematics co-develop is important from both theoretical and pedagogical standpoints. Previous research has provided mixed results. This paper investigates the development of reading and mathematics in a longitudinal sample of N = 355,883 students from the United Kingdom (2005-2019) aged 5 to 12 (49% girls).…

Nationally representative data from the Early Childhood Longitudinal Study Kindergarten Class of 2011 (n = 14,370) were used to examine the grade-level and cumulative outcomes of school absenteeism between kindergarten and fifth grade for students' school performance in the United States. Students who were more frequently absent in any year of…

Food routines are an ecocultural asset of Latino families. This cluster-randomized trial with 248 children (M[subscript age] = 67 months; 50% girls; 13 schools) investigated the impact of a 4-week family program designed to capitalize on food routines in improving Latino kindergarteners' outcomes in the United States. There were moderate-to-large…

The academic achievement places children on a positive trajectory for their lifespan. The aim of this study was to examine the academic trajectories of children in out-of-home care (OOCH) and whether kinship care has a protective effect relative to nonkin foster care. The sample analyzed for this study consists of 519,306 racially diverse youth in…

Dimensional comparisons (i.e., comparing own performances across domains) may drive an increasing differentiation in students' math and verbal self-concepts over time, but little longitudinal research has directly tested this assumption. Using cross-sequential data spanning Grades 1-12 (N = 1069, ages 6-18, 92% White, 2% Black, 51% female,…

This four-wave longitudinal study among 698 Chinese early adolescents explored (1) how personal identity coherence and confusion develop; and (2) whether parenting style and peer relationships (i.e., close friend relationships and peer preference) were related to personal identity development. Participants (M[subscript age] = 11.39 yrs.,…

Place value concepts were measured longitudinally from kindergarten (2017) to first grade (2018) in a diverse sample (n = 279; M[subscript age] = 5.76 years, SD = 0.55; 135 females; 41% Black, 38% White, 8% Asian, 12% Latino). Children completed three syntactic tasks that required an explicit understanding of base-10 symbols and three approximate…

Using data from the All Our Families study, a longitudinal study of 1992 mother-child dyads in Canada (47.7% female; 81.9% White), we examined the developmental pathways between infant gestures and symbolic actions and communicative skills at age 5. Communicative gestures at age 12 months (e.g., pointing, nodding head "yes"), obtained…
