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…

Many studies examine how bilinguals and monolinguals differ in their executive function abilities at one time-point or cross-sectionally. Fewer examine how these groups of children may differ over time. Using nationally representative data obtained from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K:2011), this…

Guided by evolutionary-developmental models, this study tested the hypothesis that children's exposure to parental relationship instability, defined by initiation and dissolution of caregiver intimate relationships, has both costs in cognitive impairments and benefits in enhanced learning skills. Participants included 243 mothers and their…

This study used a person-centered approach to examine mother-daughter dyad behaviors when jointly solving addition problems during a card game. The goal was to identify maternal and child profile behaviors during the interaction as predictors of children's autonomous addition accuracy and strategy use at the end of first grade. Videotaped…

The role of working memory (WM) in language acquisition has been widely reported in the developmental literature, but few studies have explored the role of sentence recall in the way WM and related linguistic abilities evolve. This study seeks to explore the organization and development of the memory architecture underlying language using a…

Relations between reading and writing have been studied extensively, but the less is known about the developmental nature of their interrelations. This study applied latent change score modeling to investigate longitudinal relations between reading and writing skills at the word, sentence, and text levels. Latent change score models were used to…

Research Findings: Several recent studies carried out in the United States and abroad (i.e., Asia and Europe) have demonstrated that the ability of young children to regulate their behavior (including inhibitory control, working memory, attentional control) significantly predicts their academic achievement. The current study examined the…

In recent years, there has been an increasing focus on the role played by basic numerical magnitude processing in the typical and atypical development of mathematical skills. In this context, tasks measuring both the intentional and automatic processing of numerical magnitude have been employed to characterize how children's representation and…

This study investigated kindergarten, preschool, and first-grade children who were typical or specific language impaired (SLI) to determine whether there were developmental differences in their phonological awareness abilities (i.e., syllable, onset/rime, phonemes). Results revealed a significant difference between children who were typical and…

The aim of the present study was to investigate the grain size predominantly used by children learning to read and spell in Indonesian. Indonesian is an orthographically transparent language, and the syllable is a salient unit. Tasks assessing various levels of phonological awareness as well as letter knowledge, reading familiar words and…

Task persistence, measured by a composite score of independent teacher, tester and observer reports, was examined using behavioral genetic analysis. Participants included 92 monozygotic and 137 same-sex dizygotic twin pairs in Kindergarten or 1st grade (4.3 to 7.9 years old). Task persistence was widely distributed, higher among older children,…
