For comparisons named “Big versus Small Movers,” subjects are evenly divided into two subgroups by the levels of 
. For “Quartiles” comparisons, subjects are evenly divided into four subgroups by 
. Quartile 1 contains the subjects having the biggest head movements, and Quartile 4 includes the subjects having smallest head movements. The seed location is in the left posterior cingulate cortex (PCC) at [4L, 55P, 26S] mm in MNI coordinates. The threshold level is FWE-corrected α<0.05.
