TABLE 5.

Results of the group-level gPPI analysis with the ROI in the right IFG, associated with the observation of provocation from anonymous and known opponents (uncorrected p < 0.001 at the voxel level, FWE-corrected at the cluster level p < 0.05, and k = 15).

	Cluster		Peak			Peak MNI coordinates
Brain area	p(FWE-corr.)	K	p(unc.)	F	Z	x	y	z
“Feedback” phase: Anonymous opponent > Known opponent
L Inferior frontal g.	0.011	91	<0.001	22.20	4.34	–39	41	5
No significant changes were obtained for the “Feedback” phase: Known opponent > Anonymous opponent

k, cluster size in voxels; FWE, familywise error correction; ROI, region of interest; L/R, left/right hemisphere; g., gyrus.
