The number of older siblings a child has is negatively correlated with the child's verbal skills, an effect that is well known in the literature. However, few studies have examined the effect of older siblings' sex, of the age gap between siblings, of having foreign-speaking parents, as well as the mediating role of parental interaction. Using…

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…

There is evidence of a relation between the approximate number system (ANS) and later mathematics achievement. Researchers have proposed various mediators of this relation, including executive functioning (EF), numeral knowledge, and mathematical language. The goal of the present study was to determine which factors mediate the relation between…

Poorer language ability has been shown to predict the development of externalizing behavior problems such as aggression and conduct problems. However, the developmental process that links poorer language ability to externalizing problems is unclear. The present study examined (a) whether within-child changes in language ability predict…

One of the aims for compulsory education is to diminish or alleviate differences in children's skills existing prior to school entry. However, a growing gender gap in reading development has increasingly been documented. Regrettably, there is scant evidence on whether differences between genders (favouring girls) have their roots in pre-reading…

Purpose: This study investigated the longitudinal development of 2 important contributors to reading comprehension, grammar, and vocabulary skills. The primary interest was to examine the trajectories of the 2 skill areas from preschool to 3rd grade. Method: The study involved a longitudinal sample of 420 children from 4 sites. Language skills,…

Research Findings: Growing international evidence points to high-quality teacher-child interactions in early learning environments as key contributors to children's learning and development. Little is known, however, about the longitudinal effects of these experiences, particularly in the Chinese context. In this study, we addressed the question…

Purpose: The purpose of this study was to explore the literature on predictors of outcomes among late talkers using systematic review and meta-analysis methods. We sought to answer the question: What factors predict preschool-age expressive-language outcomes among late-talking toddlers? Method: We entered carefully selected search terms into the…

A substantial body of research has demonstrated the efficacy of early writing interventions that target skills and composing processes; however, much less is known about the effectiveness of classroom writing instruction outside of the context of an intervention. The goal of this study was to investigate if writing instruction and student practice…

Children with hearing loss are at risk for developing psychosocial problems. Children with mild to severe hearing loss are less frequently subject to research, in particular in preschool, and we therefore know less about the risk in this particular group. To address this, we compared psychosocial functioning in thirty-five 4-5-year olds with…

Wolf and Bowers (1999) described a model in which phonological awareness (PA) and naming speed (NS) make independent contributions to reading ability. We tested this model in a sample of 201 Grade 3 Arabic-speaking children in Dubai, United Arab Emirates. Measures of general cognitive ability, vocabulary, PA, NS, word reading, and reading…

Purpose: Children with specific language impairment (SLI) often have vocabulary impairments. This study evaluates longitudinal growth in a latent trait of receptive vocabulary in affected and unaffected children ages 2;6 (years;months) to 21 years and evaluates as possible predictors maternal education, child gender, and nonverbal IQ. Method: A…

The purpose of this quantitative study was to compare and evaluate two types of vocabulary interventions using grade 9 physics vocabulary terms using two lists of 10 words. A quasi-experimental crossover research design was used to compare the two interventions, presented during two separate sessions, 1) active, multimedia that includes the…

Experts in children's literature and child development value complexity in the language, socio-emotional content, and structure of books, yet little is known regarding parents' attitudes towards these aspects. The study thus examined how parents' gender, education, and profession, children's age and gender, and frequency of parent-child reading…

This study focuses on three main goals: First, 3-year-olds' spatial assembly skills are probed using interlocking block constructions (N = 102). A detailed scoring scheme provides insight into early spatial processing and offers information beyond a basic accuracy score. Second, the relation of spatial assembly to early mathematical skills…
