Passolunghi, Maria Chiara; Mammarella, Irene Cristina – Journal of Learning Disabilities, 2012
This study examines visual and spatial working memory skills in 35 third to fifth graders with both mathematics learning disabilities (MLD) and poor problem-solving skills and 35 of their peers with typical development (TD) on tasks involving both low and high attentional control. Results revealed that children with MLD, relative to TD children,…

Barnes, Marcia A.; Wilkinson, Margaret; Khemani, Ekta; Boudesquie, Amy; Dennis, Maureen; Fletcher, Jack M. – Journal of Learning Disabilities, 2006
Three studies compared 98 children with spina bifida myelomeningocele (SBM)--a disorder associated with high rates of math disability and spatial deficits--to 94 typically developing children on multidigit subtraction and cognitive addition tasks. Children with SBM were classified into those with reading decoding and math disability, only math…

Are Mathematics Disabilities Due to a Domain-General or a Domain-Specific Working Memory Deficit?
Peer reviewed Peer reviewed
Wilson, Kathleen M.; Swanson, H. Lee – Journal of Learning Disabilities, 2001
The relationship between verbal and visual-spatial working memory and mathematical computation skill was examined in 98 children and adults with and without mathematical disabilities. A hierarchical regression analysis, when partialing for reading ability, age, and gender influences, showed mathematical computation was better predicted by verbal…

Does Strategy Knowledge Influence Working Memory in Children with Mathematical Disabilities?
Peer reviewed Peer reviewed
Keeler, Marsha L.; Swanson, H. Lee – Journal of Learning Disabilities, 2001
A study investigated the relationship between working memory (WM), declarative strategy knowledge, and math achievement in 111 children with and without mathematical disabilities (MD). Results found verbal and visual-spatial WM, stable verbal strategy choices, and expert strategy choices related to visual-spatial processing all contributed…
