Students with Attention-Deficit/Hyperactivity Disorder (ADHD) are struggling writers. Yet no comprehensive model has been validated to explain their poor writing outcomes. This study aims to test whether an extended version of the Not-So-Simple View of Writing (NSVW) model can describe the effects of key abilities on writing performance in…

Young children are often enrolled in either AM (morning) or PM (afternoon) sessions in early childhood programs. However, little research is available on this routine practice. We used multilevel analysis to investigate if there are differences in the literacy, math, and social outcomes for children who participate in AM or PM sessions beyond…

This study explored the role of growth in the executive components of working memory (WM) on second language (L2) mathematical problem-solving in elementary school children who are emerging bilinguals whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 at Wave 1 were administered a battery of math, reading,…

Using nationally representative data from the Family and Child Experiences Survey 2009 Cohort (n = 2,798), this study examined patterns of absenteeism and their consequences through the transition to kindergarten. Overall, children were less likely to be absent in kindergarten than from Head Start at ages 3 and 4. Absenteeism was fairly stable…

This study investigated the contribution of fine and gross motor skills to academic and attentional performance at school entry among 832 boys and girls. Children were tested on their fine and gross motor skills (locomotor, object control) and their academic performance in receptive vocabulary, number knowledge, and attentional skills at 6 to 7…

Longitudinal data from the children of the National Longitudinal Survey of Youth (NLSY) were used to assess how well measures of short-term and working memory and attention in early childhood predicted longitudinal growth trajectories in mathematics and reading comprehension. Analyses also examined whether changes in memory and attention were more…

The present longitudinal study investigated the developmental trajectories of addition, subtraction, and multiplication fluency; their relationships to general cognitive functions; and potential interrelations between reading fluency and growth in arithmetic fluency for different operations. The central prediction was that measures of arithmetic…

Research Findings: The study examined the relationship between Spanish-speaking DLL children's engagement within the preschool classroom with teachers, peers, and tasks and their school readiness skills compared to monolingual English-speaking peers. Results suggested that DLL children had lower language skills and phonological awareness by the…

Many recent studies have aimed to demonstrate that specific types of reading comprehension depend on different underlying cognitive abilities. In these studies, it is often implicitly assumed that reading comprehension is a multidimensional construct. The general aim of this study was to examine the dimensionality of a large pool of reading…

Family processes and parenting practices help explain developmental differences between children in low- versus higher-income households. There are, however, few studies addressing the question of: what are the key family processes and parenting practices for promoting low-income children's growth? We address this question in the present study,…

Research Findings: Early reading and mathematics skills predict later academic success, and child self-regulation and secure parent-child relationships are both predictors of early academic skills. Self-regulatory and family relationship factors have rarely been studied together as predictors of early academic success in populations of young…

This study is a conceptual replication of a widely cited study by Moffitt et al. (2011) which found that attention and behavior problems in childhood (a composite of impulsive hyperactive, inattentive, and impulsive-aggressive behaviors labeled "self-control") predicted adult financial status, health, and criminal activity. Using data…

Purpose: Researchers have developed a constellation model of decodingrelated reading disabilities (RD) to improve the RD risk determination. The model's hallmark is its inclusion of various RD indicators to determine RD risk. Classification methods such as logistic regression (LR) might be one way to determine RD risk within the constellation…

The mental lexicon plays a central role in reading comprehension (Perfetti & Stafura, 2014). It encompasses the number of lexical entries in spoken and written language (vocabulary breadth), the semantic quality of these entries (vocabulary depth), and the connection strength between lexical representations (semantic relatedness); as such, it…
