RUNNING HEAD: Number Sense and Developmental Dyscalculia Number Sense and Developmental Dyscalculia

In this chapter we review the possible biological bases for developmental dyscalculia, which is a disorder in mathematical abilities presumed to be due to impaired brain function. By reviewing what is known about the localization of numerical cognition functions in the adult brain, the causes of acquired dyscalculia, and the normal development of numerical cognition, we propose several hypothes...

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...

Developmental Dyscalculia: A Cognitive Neuroscience Perspective

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 interventi...

Developmental dyscalculia, gender, and the brain.

Background Developmental dyscalculia is a primary cognitive disorder of childhood affecting the ability of an otherwise intelligent and healthy child to learn arithmetic.' Preliminary evidence indicates that developmental dyscalculia is seen in 5-6% of normal children2 3 and is as prevalent as developmental dyslexia or the attention deficit hyperactivity disorder.' One of the classifications of...

When Your Brain Cannot Do 2 + 2: A Case of Developmental Dyscalculia

Children who have great difficulties learning simple arithmetic problems may have a little-known learning problem known as developmental dyscalculia. Children with dyscalculia have math abilities that are much lower than those of their friends who are of the same age. Also, their difficulties are long lasting, and you cannot explain their problems by poor teaching or by other brain disorders. E...
