Dyscalculia is characterized by high heterogeneity of symptoms and impairment on a range of basic computational skills, such as counting, number fact knowledge, written calculation and mathematical reasoning.
In contrast to patients showing at least one linguistic advantage in semantic comparison, they were more accurate in addition, subtraction, multiplication, division, mental as well as written calculation and showed more numerical advantages but less linguistic advantages across all tasks.
According to further analyses, L patients in contrast to N patients also differed in other tasks requiring numerical semantic knowledge, e.g., simple addition, subtraction, multiplication, division, mental as well as written calculation, and showed less numerical advantages but more linguistic advantages over all tasks.
Post-hoc analyses revealed that patients with two linguistic advantages in fact retrieval were more impaired in subtraction, multiplication, mental as well as written calculation and, most interestingly, quit multiplication tasks significantly more often than patients without dissociation (see Additional file 2).
We discuss the use of the abacus and finger reckoning as well as written calculations.
