Empirical evidence supports the importance of executive function (EF) in reading, but the underlying mechanism through which EF contributes to the reading process is unclear. The present study examined the direct and indirect effects of EF on reading comprehension through the indirect pathway of language and cognitive skills (i.e., syntactic…

We examined the relations between working memory, emergent literacy skills (e.g., phonological awareness, orthographic awareness, rapid-automatized naming), word reading, and listening comprehension to online reading processes (eye movements), and their relations to reading comprehension. A total of 292 students were assessed on working memory and…

We examined the Direct and Indirect Effects model of Writing (DIEW), using longitudinal data from Korean-speaking beginning writers. DIEW posits hierarchical structural relations among component skills (e.g., transcription skills, higher order cognitive skills, oral language, motivation/affect, background knowledge) where lower level skills are…

This study determined the working memory (WM) components (executive, phonological short-term memory [STM], and visual-spatial sketchpad) that best predicted mathematical word problem-solving accuracy in elementary schoolchildren (N = 392). The battery of tests administered to assess mediators between WM and problem-solving included measures of…

We examined the Direct and Indirect Effects model of Writing (DIEW), using longitudinal data from Korean-speaking beginning writers. DIEW posits hierarchical structural relations among component skills (e.g., transcription skills, higher order cognitive skills, oral language, motivation/affect, background knowledge) where lower level skills are…

This study examined the Chinese written composition development of elementary-grade students in relation to the simple view of writing. Measures of nonverbal reasoning ability, component skills of transcription (stroke sequence knowledge, word spelling, and handwriting fluency), oral language (definitional skill, oral narrative skills, and…

This study demonstrates the utility of applying a causal indicator modeling framework to investigate important predictors of reading comprehension in third, seventh, and tenth grade students. The results indicated that a 4-factor multiple indicator multiple indicator cause (MIMIC) model of reading comprehension provided adequate fit at each grade…

The present study utilized a latent variable modeling approach to examine the Simple View of Reading in a sample of students from 3rd, 7th, and 10th grades (N = 215, 188, and 180, respectively). Latent interaction modeling and other latent variable models were employed to investigate (a) the functional form of the relationship between decoding and…

We examined the role of executive attention, which encompasses the common aspects of executive function and executive working memory, in children's acquisition of two aspects of mathematical skill: (a) knowledge of the number system (e.g., place value) and of arithmetic procedures (e.g., multi-digit addition) and (b) arithmetic fluency (i.e.,…

A 4-stage developmental model, in which auditory sensitivity is fully mediated by speech perception at both the segmental and suprasegmental levels, which are further related to word reading through their associations with phonological awareness, rapid automatized naming, verbal short-term memory and morphological awareness, was tested with…

Recent intervention studies directed to improve problem solving accuracy in children with math difficulties (MD) have found support for teaching cognitive strategies. This study addresses the question: What role does working memory capacity (WMC) play in strategy outcomes for children with MD? Four prediction models can be applied to strategy…

Math achievement is not a unidimensional construct but includes different skills that require different cognitive abilities. The focus of this study was to examine associations between a number of cognitive abilities and three domains of math skills (knowing, applying and problem solving) simultaneously in a multivariate framework. Participants…

In this study, we explored whether the contribution of working memory (WM) to children's (N = 471) 2nd language (L2) reading and language acquisition was best accounted for by processing efficiency at a phonological level and/or by executive processes independent of phonological processing. Elementary school children (Grades 1, 2, & 3) whose…

This study determined the working memory (WM) components (executive, phonological loop, and visual-spatial sketchpad) that best predicted mathematical word problem-solving accuracy of elementary school children in Grades 2, 3, and 4 (N = 310). A battery of tests was administered to assess problem-solving accuracy, problem-solving processes, WM,…

This study investigated the structure and development of processes involved in "g." One hundred and forty children, about equally drawn among primary school grades 1-6 were examined by four types of Stroop-like speeded tasks addressed to processes of increasing complexity (i.e., speed of processing, perceptual discrimination, perceptual control,…
