Developmental dyscalculia behavioral and attentional aspects: a research note.

Behavioral characteristics of 140 children with developmental dyscalculia (DC) were evaluated using the Child Behavior Checklist. DC children demonstrated more behavior problems than normal children but significantly fewer problems than children psychiatrically referred. DC children had significantly more attentional problems although they had normal levels of anxiety/depression. Significantly higher scores on all syndrome scales were found for DC children who had attentional problems in the clinical range. When associated with dyslexia and a low verbal IQ, DC children had more attentional problems and externalizing syndromes. The implications of the behavioral characteristics of DC are discussed.
