Li, Danfeng; Zhang, Xuejing; Zhang, Li – Journal of Learning Disabilities, 2023
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…

Liu, Allison S.; Rutherford, Teomara; Karamarkovich, Sarah M. – Journal of Educational Psychology, 2022
Cognitive, numeracy, and motivational factors have been implicated in math achievement. However, few studies have investigated these factors simultaneously and in middle childhood, limiting our understanding of the relative contributions of these factors during an important developmental period. The current study investigated how one numeracy,…

López, Magdalena – Electronic Journal of Research in Educational Psychology, 2014
Introduction: This study has aimed to investigate the relationship between the development of working memory and performance on arithmetic activities. Method: We conducted a 3-year longitudinal study of a sample of 90 children, that was followed during the first, second and third year of primary school. All children were tested on measures of WM…

Costa, Lara-Jeane; Green, Melissa; Sideris, John; Hooper, Stephen R. – Journal of Learning Disabilities, 2018
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…

Swanson, H. Lee; Fung, Wenson – Journal of Educational Psychology, 2016
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…

Brandenburg, Janin; Klesczewski, Julia; Fischbach, Anne; Schuchardt, Kirsten; Büttner, Gerhard; Hasselhorn, Marcus – Journal of Learning Disabilities, 2015
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…

Campos, Isabel S.; Almeida, Leandro S.; Ferreira, Aristides I.; Martinez, Luis F.; Ramalho, Gloria – European Journal of Psychology of Education, 2013
The present study aims to examine the relationship between cognitive factors and mathematical achievement in primary education. Participants were 103 Portuguese third grade students, aged 8 and 9. All participants completed a battery for working memory (WMTB-C), a test of general intelligence (Raven's Progressive Color Matrices), a selective…
