TI  - An epidemiological study of number processing and mental calculation in Greek 
      schoolchildren.
PG  - 377-88
AB  - The aim of this study was to validate and standardize an instrument for the 
      diagnosis of developmental dyscalculia (mathematics disorder) in a Greek 
      population and to obtain relevant epidemiological data. We used the 
      Neuropsychological Test Battery for Number Processing and Calculation in Children 
      (NUCALC) in a community sample of 240 students ages 7 to 11 years from urban and 
      rural schools. There were no differences between genders in arithmetical 
      performance; however, the effects of grade and socioeconomic level were 
      significant. Prevalence was higher in the rural than in the urban area. A 
      cross-cultural comparison of the Greek data with those obtained with the same 
      instrument in other countries in schoolchildren of the same age was performed.
