ABSTRACT
Developmental dyscalculia (DD) is a specific learning disorder that prevents the acquisition of basic arithmetic and numerical skills. DD symptoms include severe difficulties in solving arithmetic and mathematical problems. DD emerges from the impaired scaffold that the ANS provides to the acquisition of numerical skills. In children suffering from DD, the ANS is comparably more imprecise and hence provides only limited support during the acquisition of numerical skills. Most of the hitherto cited studies focus on areas that have been shown to be crucially involved in numerical cognition, therefore adopting a domain-specific approach to explain DD. Adopting a systemic approach, V. Menon and T. Iuculano propose that DD may arise from deficits in various brain systems that jointly contribute to mathematical cognition. The development of a coherent theoretical framework for the emergence of DD is crucial for designing targeted interventions that successfully remedy DD.
