Covariates are shown in grey. N = 181. †p < 0.10, ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001. M(SD) for bias measures are by definition 0(1) – see Methods for details. Note also that bias scores are residualized against math and verbal performance, respectively, so means for bias scores and correlations between a bias and a performance score are necessarily 0.
