Supplementary materials to “Vanbinst, K., Ghesquière, P., & De Smedt, B. (2019). Is the long-term association between symbolic numerical magnitude processing and arithmetic bi-directional? Journal of Numerical Cognition, 5(3), 358-370. https://doi.org/10.5964/jnc.v5i3.202” The following data of the participants under study were included: number for each participant (subject.nr), age (Age_start in years), gender, (girl;1), performance on a symbolic comparison task at the start and at the end of primary education (Symbolic_comparison_start; Symbolic_comparison_end), performance on a motor response speed task (Motor_speed_start), arithmetic achievement at each time point (Arithmetic_start; Arithmetic_end), and finally, nonverbal_reasoning. notReviewed publishedVersion
