Table 4.
Multiple regression models for each ANS acuity measure, with basic arithmetic fluency (addition and subtraction) as dependent variable and perceptual speed, intelligence (Raven's matrices) as predictors.

Note: Signs of the beta-weights have been transformed so that a positive sign indicates a positive association.
