Supplementary materials to: Revisiting and refining relations between nonsymbolic ratio processing and symbolic math achievement

Supplementary materials to: Park, Y., & Matthews, P. G. (2021). Revisiting and refining relations between nonsymbolic ratio processing and symbolic math achievement. Journal of Numerical Cognition, 7(3), 328-350. https://doi.org/10.5964/jnc.6927 The Supplementary Materials contain the following additional information: 1. Analysis of the relations between ratio acuities measured by Weber fractions (ws) and math abilities. 2. Bivariate correlation tables relating performance among various comparison tasks and math tasks, as well as inhibitory control. Separate tables were constructed, alternatively using accuracy and ws as the performance metric. Tables were also constructed with and without the use of listwise deletion. 3. Results from the hierarchical regression analyses predicting math abilities from ws. 4. Results from the hierarchical regression analyses predicting symbolic fraction comparison without including Ravens as a covariate.
