Table 3.
Partial correlations between measures of ANS acuity and exact calculation, controlling for age, intelligence and spelling.
Table 4.
Stepwise regression with exact calculation as the dependent variable and non-symbolic comparison, non-symbolic estimation and non-symbolic addition as predictors, regressing out the effects of age, schooling, general intelligence and spelling abilities.
