Abbreviations: IFG: inferior frontal gyrus; IPS, intraparietal sulcus; MFG, middle frontal gyrus; SFG, superior frontal gyrus.
Specified are the examined anatomical regions and their MNI coordinates based on Fox et al. (2006), as well as the corresponding cluster sizes (in voxels), peak voxel MNI coordinates, and t- as well as P FWE-values.
P values ≤ .05 were considered significant, P values ≤ .1 were considered trends.
