For the interaction effects, we listed those clusters that reached significance with a P<0.005 AlphaSim corrected voxel threshold. For each cluster we reported the F-value, Z-value and MNI coordinates at the position of the maximum, the cluster size and the appropriate Brodmann Area (BA). For each significant cluster of the post hoc results, we reported the T-value, Z-value and MNI coordinates at the position of the maximum, the cluster size and the appropriate BA.
