Longitudinal regression analysis (Table 4, model 1) in the same preschool sample; the authors report that "initial math ability accounted for the largest amount of variability in later math ability (45%)" while ANS accuracy and RT contributed 7% and 6%.

"initial math ability accounted for the largest amount of variability in later math ability (45%), whereas accuracy and RT on the ANS acuity task only contributed 7% and 6% respectively"
