In this paper, Luria's model of arithmetic calculation is reviewed. Luria's investigations could be subdivided into two branches: (1) evaluation of the concept or rank order; and (2) evaluation of computational processes. Causes of dyscalculia and location of lesion effects are also commented on. Luria broadly conceptualized the dyscalculias into spatial and verbal components with spatial deficits subdivided into visual and imaginal. Luria did not offer a complete model of dyscalculia, nor did he use error analyses: he also claimed that most acalculias were secondary to more basic aphasic disorders.
