Children with developmental dyscalculia struggle with math fact memorization and simple arithmetic. However, their understanding of number concepts remains intact, suggesting specific cognitive deficits.

Area of Science:

Neuroscience
Developmental Psychology
Educational Psychology

Background:

Developmental dyscalculia is a learning disorder affecting arithmetic skills.
Understanding the specific cognitive deficits is crucial for targeted interventions.

Purpose of the Study:

To neurobehaviorally evaluate children with developmental dyscalculia.
To identify affected aspects of arithmetic processing.

Main Methods:

Neurobehavioral evaluation of eleven children diagnosed with developmental dyscalculia.

Main Results:

Impaired memorization of numerical facts and solving simple arithmetic exercises.
Intact comprehension and production of number functions.

Associated mild dyslexia, dysgraphia, anomia, and grapho-motor dysfunction.

Conclusions:

Cognitive mechanisms for arithmetic skills are developmentally dissociable.
Remediation requires detailed analysis of arithmetic and associated cognitive skills.
