The order of the tests (AMAS-TTR-CDR or TTR-CDR-AMAS) did not have an impact on math anxiety itself (t(87) = 1.39, p = 0.17), nor on the correlations between math anxiety and the two indices of mathematics achievement (i.e., partial correlations of r = -0.15, p = 0.17 between math anxiety and TTR and r = -0.14, p = 0.19 between math anxiety and CDR when controlling for the order of the test). This evidence concerns the gene TTR and Anxiety.
