Objective: Executive Function (EF) is thought to be a core component of various cognitive processes. Two common ways to measure EF are through report-based measures that assess EF by collecting informant(s) reports on children's behaviors, and performance-based measures that assess EF through the completion of a task related to EF dimension(s).…

Children's ability to discriminate nonsymbolic number (e.g. the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest it may be due to a sharpening numerical representation or an improved ability…

In the current study, we investigated the role of executive functions in explaining how word recognition and language comprehension jointly predict reading comprehension in multilingual and monolingual students (Grades 1 and 2). Specifically, mediation and moderation models were tested and compared to offer a more nuanced understanding of the role…

Dual language learner children (DLLs) benefit from early childhood education (ECE) and learning multiple languages, but research has predominantly focused on English monolingual children, with limited insight on the ECE and early development of DLLs. This study investigated whether DLLs' developmental assets assessed at pre-k entry (i.e. English…

This study of children from two U. S. states examined associations among four cognitive and academic skills: executive function (EF), visuo-motor integration, mathematics assessed with applied problems, and letter-word knowledge. Before (T1) and after (T2) kindergarten, children (N=555) were assessed using the Head-Toes-Knees-Shoulders (HTKS) EF…

Behavioral self-regulation supports young children's learning and is a strong predictor of later academic achievement. The capacity to manage one's attention and control one's behavior is commonly measured via direct assessments of executive function (EF). However, to understand how EF skills contribute to academic achievement, it is helpful to…

Detecting a pattern within a sequence of ordered units, defined as patterning, is a cognitive ability that is important in learning mathematics and influential in learning to read. The present study was designed to examine relations between first-grade children's executive functions, patterning, and reading abilities, and to examine whether these…

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…

Research has illuminated contributions--usually modeled separately--of both executive functioning (EF) and visuomotor integration (VMI) to mathematical development in early elementary school. This study examined simultaneous associations of EF and VMI, measured at the beginning of the school year, with concurrent and later mathematics performance…

Recent studies suggest that the relation between nonsymbolic magnitude processing skills and math competence is mediated by symbolic number processing. However, less is known about whether mapping between nonsymbolic and symbolic magnitude representations also mediates that relation, and whether the mediating role of symbolic number processing is…

Books designed for beginning readers typically intermix text with illustrations in close proximity. Prior research suggests this standard layout may reduce literacy skills due to increased attentional competition between text and illustrations. The current study extends this work by examining whether manipulations to the book layout can enhance…

The primary aim of this study was determining Grade 1 cognitive predictors of students at risk for writing disabilities in Grades 2 through 4. Applying cognitive measures selected to align with theoretical and empirical models of writing, tasks were administered to Grade 1 students assessing fine-motor, linguistic, and executive functions: 84 at…
