Across all of the univariate analysis, any participants showing < mean 0.2% signal change, calculated across single-task and multitask conditions at the pretraining session, were excluded from the analysis for that ROI (Univariate MRI Analysis). ACC, anterior cingulate cortex; DLPFC, dorsolateral prefrontal cortex; IFG, inferior frontal gyrus; MFG, medial frontal gyrus; PCC, posterior cingulate cortex; pLPFC, posterior lateral prefrontal cortex; Region: brain region; SMFC, superior medial frontal cortex; SMG, supramarginal gyrus; TAL: Talairach coordinates; TPJ, temporal parietal junction; Training, N/Control, N, number remaining in training and control groups after excluding participants showing <0.2% signal change.
