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…

Since COVID-19 pandemic started, schools had to face environmental changes, one was shifting from a face-to-face educational approach to online learning. It represented an unfavourable learning environment, especially for children with Specific Learning Disabilities (SpLD). Following the Self Determination Theory (SDT) framework, the current study…

The role of executive function (EF) in the reading process, and in those with reading difficulties, remains unclear. As members of the Texas Center for Learning Disabilities, we review multiple perspectives regarding EF in reading and then summarize some of our recent studies of struggling and typical readers in grades 3-5. Study 1a found that a…

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…

Written language is a difficult endeavour as the demands of transcription require self-regulatory skills from a motor, cognitive and attention perspective. The purpose of the present study was to investigate the relation between the Test of Writing Difficulties (Porpodas et al., 2007) and the Test of Detection and Investigation of Executive…

In transparent orthographies like German, isolated learning disabilities in either reading or spelling are common and occur as often as a combined reading and spelling disability. However, most issues surrounding the cognitive causes of these isolated or combined literacy difficulties are yet unresolved. Recently, working memory dysfunctions have…

Children with specific learning disabilities (SLD) have deficits in the basic psychological processes that interfere with learning and academic achievement, and for some SLD subtypes, these deficits can also lead to emotional and/or behavior problems. This study examined psychosocial functioning in 123 students, aged 6 to 11, who underwent…

Relationships between attention/executive functions and language learning were investigated in students in Grades 4 to 9 (N = 88) with and without specific learning disabilities (SLDs) in multiword syntax in oral and written language (OWL LD), word reading and spelling (dyslexia), and subword letter writing (dysgraphia). Prior…

The primary purpose of this study was to investigate the various neurocognitive processes concomitant to reading by attempting to identify various subtypes of reading disorders in a referred sample. Participants were 216 elementary school students in grades two through five who were given select subtests of the Woodcock Johnson-III Tests of…

Children with mathematics difficulties suffer from working memory deficits. This study investigated the deficit profile of phonological storage and executive functions in working memory among children with mathematics difficulties. Based on multiple instruments and two assessment points, 68 children were screened out of 805 fifth graders. Of these…

This study explored the relationship between verbal fluency skills and writing skills in developing writers. There were three research questions addressed: (1) Was there a difference between fifth-grade students who have a learning disability (LD) in written language and fifth-grade students with typical development (TD) on the Delis-Kaplan…
