Developmental dyscalculia (DD) is a mathematics learning disorder that affects approximately 5% to 7% of the population. This study aimed to detect the underlying domain-specific and domain-general differences between DD and typically developing (TD) children. We recruited 9-year-old primary school children to form the DD group via a 2-year…

The development of executive functions (EF) in bilingual children with a specific learning disorder (SLD) is a growing area of research interest. Our objective is to study the development of EF in Lebanese children with typical development (TD) and presenting SLD, in the primary grades (Grades 2, 3, and 4). Ninety TD and ninety SLD children, in…

Purpose: Compared to children with typical development, children with dyslexia, developmental language disorder (DLD), or both often demonstrate working memory deficits. It is unclear how pervasive the deficits are or whether the deficits align with diagnostic category. The purpose of this study was to determine whether different working memory…

This study investigated the prevalence of latent classes at risk for reading or math disabilities in elementary-age children whose first language is Spanish. To this end, children (N = 394) in Grades 1, 2, and 3 were administered a battery of vocabulary, reading, math, and cognitive measures in both Spanish and English. Three important findings…

In the past years, an increasing number of studies have investigated executive functions as predictors of individual differences in mathematical abilities. The present longitudinal study was designed to investigate whether the executive functions shifting, inhibition, and working memory differ between low achieving and typically achieving children…
