Stroop task LMM results for (A) Accuracy; and (B) RT.

Since there were 3 trial types (Control, Congruent, Incongruent), condition was coded as a contrast between Incongruent and each of the other conditions (Control, Congruent). Significant predictors involving these contrasts were then explored further with a multi-parameter effects test to assess the significance of the main effect of condition. All post hoc EMM comparisons are adjusted for multiple comparisons using Tukey’s HSD (pHSD). To correct for multiple LMMs being conducted in this study (7 in total), all p-values have additionally been adjusted with a Bonferroni correction (pcorr). Significant Bonferroni corrected findings are highlighted in bold (*
