Thousands of education institutions worldwide rely on IELTS scores as criteria for accepting international students whose first language is not English. Individual studies have found varying degrees of strength of correlations and conflicting results between IELTS entry scores and subsequent academic success. These conflicting results were…

This meta-analysis explores the correlation between self-assessment (SA) and language performance. Sixty-seven studies with 97 independent samples involving more than 68,500 participants were included in our analysis. It was found that the overall correlation between SA and language performance was 0.466 (p < 0.01). Moderator analysis was…

This study conducted two meta-analyses to synthesize the association between children's language skills and two broad-band dimensions of psychopathology: internalizing and externalizing. Pooled estimates across 139 samples (externalizing k = 105; internalizing k = 90) and 147,305 participants (age range: 2-17 years old; mean % males: 53.75; mean %…

Purpose: We report the results of a systematic review and meta-analysis investigating the relationship between perceptual anchoring and dyslexia. Our goal was to assess the direction and degree of the effect between perceptual anchoring and reading ability in typical and atypical (i.e., dyslexic) readers. Method: We performed a literature search…

We examined the relation of morphological awareness with language and literacy skills, namely phonological awareness, orthographic awareness, vocabulary, word reading, spelling, text reading fluency, and reading comprehension. We also examined potential moderators of the relations (grade level, orthographic depth of language, receptive vs.…

The literature on the association between reading comprehension and mathematics skills is complicated and conflicting. This study seeks to illuminate the nature of the association between mathematics skills and reading comprehension by incorporating potential moderators, namely components of mathematics skills, domains of content standards in…

Objective: The purpose of this article is to estimate the overall weighted mean effect of the relation between early language skills and later behavior problems in school-aged children. Method: A systematic literature search yielded 19,790 unduplicated reports, and a structured search strategy and identification procedure yielded 25 unique data…

The purpose of this review was to introduce readers of "Child Development" to the meta-analytic structural equation modeling (MASEM) technique. Provided are a background to the MASEM approach, a discussion of its utility in the study of child development, and an application of this technique in the study of reading comprehension (RC)…

Most English language teachers around the world speak English as an additional language, and their level of English proficiency is often a matter of concern for them and their employers who associate higher levels of language proficiency with more effective teaching skills. To this end, several studies have examined the relationship between…

A growing body of evidence points to the common co-occurrence of language and behavioral difficulties in children. Primary studies often focus on this relation in children with identified deficits. However, it is unknown whether this relation holds across other children at risk or representative samples of children or over time. The purpose of…

Using meta-analytic techniques, we examined systematically the evidence linking friendship to academically related outcomes, asking: To what extent is friendship related to academic performance and to academically related cognitive skills? Based on 22 studies that yielded 81 effect sizes and 28 independent samples, we examined relations between…

A meta-analysis was conducted to examine the construct validity of language aptitude by synthesizing the existing research that has been accumulated over the past five decades. The study aimed to provide a thorough understanding of the construct by aggregating the data reported in the primary research on its correlations with other individual…

Low language proficiency and problem behavior often co-occur, yet language deficits are likely to be overlooked in children with emotional and behavioral disorders (EBD). Random effects meta-analyses were conducted to determine prevalence and severity of the problem. Across 22 studies, participants included 1,171 children ages 5-13 with formally…

This article examines associations between observed quality in preschool center classrooms for approximately 6,250 three- to five-year-olds and their school readiness skills at kindergarten entry. Secondary analyses were conducted using data from four large-scale studies to estimate the effects of preschool center quality and interactions between…

This research synthesis examines whether the association between print exposure and components of reading grows stronger across development. We meta-analyzed 99 studies (N = 7,669) that focused on leisure time reading of (a) preschoolers and kindergartners, (b) children attending Grades 1-12, and (c) college and university students. For all…
