Fig. 3.

Permutation test results and bootstrap confidence intervals for (A) accuracy and (B) median RT measures. DD minus control difference scores are shown. Permutation and t-test p values and mean effect sizes (accuracy and RT) are shown below figures. Significant correlations between measures and maths performance are shown in the figure if significant or marginal (r and p values). Significant group differences are marked by red bars, text and stars. Marginal results are marked by orange bars, text and crosses.
