TL;DR: A review of the arithmetical competencies of school-age children with memory and cognitive deficits and a more general framework for linking research in mathematical cognition to research in learning disabilities is provided.
Abstract: Between 5% and 8% of school-age children have some form of memory or cognitive deficit that interferes with their ability to learn concepts or procedures in one or more mathematical domains. A review of the arithmetical competencies of these children is provided, along with discussion of underlying memory and cognitive deficits and potential neural correlates. The deficits are discussed in terms of three subtypes of mathematics learning disability and in terms of a more general framework for linking research in mathematical cognition to research in learning disabilities.

TL;DR: Cognitive, neuropsychological, and genetic correlates of mathematical achievement and mathematical disability are reviewed in an attempt to identify the core deficits underlying MD.
Abstract: Cognitive, neuropsychological, and genetic correlates of mathematical achievement and mathematical disability (MD) are reviewed in an attempt to identify the core deficits underlying MD. Three types of distinct cognitive, neuropsychological, or cognitive and neuropsychological deficits associated with MD are identified. The first deficit is manifested by difficulties in the representation or retrieval of arithmetic facts from semantic memory. The second type of deficit is manifested by problems in the execution of arithmetical procedures. The third type involves problems in the visuospatial representation of numerical information. Potential cognitive, neuropsychological, and genetic factors contributing to these deficits, and the relationship between MD and reading disabilities, are discussed. Finally, suggestions for the subtyping of mathematical disorders are offered.

TL;DR: The authors found that dyscalculia is the result of specific disabilities in basic numerical processing, rather than the consequence of deficits in other cognitive abilities, with no special features consequent on their reading or language deficits.

TL;DR: The concept of numbers and the ability to recognize and process them is innate, part of everyone's intellectual apparatus whether they've had formal education or not as discussed by the authors, a fact which has implications for neuroscience and poses the question: why did man evolve with such specialized neural apparatus.
Abstract: The concept of numbers and the ability to recognize and process them is innate, part of everyone's intellectual apparatus whether they've had formal education or not. This "number instinct" is not dependent on basic intelligence or general knowledge, a fact which has implications for neuroscience and poses the question: why did man evolve with such specialized neural apparatus. It has been that the social development of humans has been crucially affected by language, yet numbers have also been critical in the advancement of human culture. Every child goes through a stage of learning to count using their ten fingers, much as early Homo Sapiens must have done. If number learning is a natural and universal function of the brain, why do so many suffer from dyscalculia? This text, containing theories and anecdote, is an investigation into the bizarre world of numbers. It examines the role of education, good or bad, in the development of mathematical disorders.

TL;DR: It is shown that number acuity improves with age in typically developing children, establishing for the first time a clear association between dyscalculia and impaired "number sense", and may open up new horizons for the early diagnosis and rehabilitation of mathematical learning deficits.
