Bugden, Stephanie; Ansari, Daniel – Developmental Science, 2016
In the present study we examined whether children with Developmental Dyscalculia (DD) exhibit a deficit in the so-called "Approximate Number System" (ANS). To do so, we examined a group of elementary school children who demonstrated persistent low math achievement over 4 years and compared them to typically developing (TD), aged-matched…

Swanson, H. Lee; Jerman, Olga; Zheng, Xinhua – Journal of Psychoeducational Assessment, 2009
This article synthesizes some of the published literature that selectively compares the cognitive functioning of children with math disabilities (MDs) with average-achieving children and poor readers (children with reading disabilities [RDs] or comorbid disabilities [RDs + MDs]). All studies in the synthesis report reading, IQ, and math scores for…

Swanson, H. Lee; Jerman, Olga – Review of Educational Research, 2006
This article synthesizes published literature comparing the cognitive functioning of children who have math disabilities (MD) with that of (a) average-achieving children; (b) children who have reading disabilities (RD); and (c) children who have co-morbid disabilities (MD+RD). Average achievers outperformed children with MD on measures of verbal…

Prevatt, Frances; Proctor, Briley – Learning Disabilities: A Multidisciplinary Journal, 2003
Two hundred four (204) college students who had difficulties in both foreign language and math (FLD/MD), only math difficulties (MD), or only foreign language difficulties (FLD) were studied. Analysis of prevalence of presenting problems indicated that FLD and FLD/MD are relatively uncommon, compared to MD. Comparisons among the three groups…
