Developmental Dyscalculia: A Cognitive Neuroscience Perspective
نویسنده
چکیده
Developmental dyscalculia (DD) is considered a brain-based disorder usually caused by dysfunction of the parietal cortex. DD has been researched but the current available means of diagnosing and particularly of treating DD are still not clearly defined. The current review discusses the different suggested neurocognitive markers of DD subtypes and links them with suggested grounds for intervention programs.

Developmental dyscalculia is related to visuo-spatial memory and inhibition impairment☆
Developmental dyscalculia is thought to be a specific impairment of mathematics ability. Currently dominant cognitive neuroscience theories of developmental dyscalculia suggest that it originates from the impairment of the magnitude representation of the human brain, residing in the intraparietal sulcus, or from impaired connections between number symbols and the magnitude representation. Howev...
متن کاملDyscalculia: from brain to education.
Recent research in cognitive and developmental neuroscience is providing a new approach to the understanding of dyscalculia that emphasizes a core deficit in understanding sets and their numerosities, which is fundamental to all aspects of elementary school mathematics. The neural bases of numerosity processing have been investigated in structural and functional neuroimaging studies of adults a...
متن کاملDevelopmental dyscalculia: Fresh perspectives
This issue of Trends in Neuroscience in Education offers some fresh perspectives on developmental dyscalculia. Here we present an overview of different theoretical approaches to identifying and defining developmental dyscalculia, and a consideration of critical measurement and experimental issues. We note a series of important caveats that must be applied when interpreting the existing research...
متن کاملFunctional hyperconnectivity vanishes in children with developmental dyscalculia after numerical intervention
Developmental dyscalculia (DD) is a developmental learning disability associated with deficits in processing numerical and mathematical information. Although behavioural training can reduce these deficits, it is unclear which neuronal resources show a functional reorganization due to training. We examined typically developing (TD) children (N=16, mean age: 9.5 years) and age-, gender-, and hand...
متن کاملA developmental model of number representation
We delineate a developmental model of number representations. Notably, developmental dyscalculia (DD) is rarely associated with an all-or-none deficit in numerosity processing as would be expected if assuming abstract number representations. Finally, we suggest that the “generalist genes” view might be a plausible though thus far speculative explanatory framework for our model of how number rep...
