For the Stroop task, a highly significant main effect was found for Condition type, F (2, 41) = 73.36, P < 0.01, but not for Group, F (2, 41) = 0.55, P = 0.58, nor the interaction between Condition type and Group, F (4, 41) = 1.02, P = 0.39. fMRI results For individual group activities on both tasks see Figure S1 .
