Notes: Only regions surviving inclusive masking with guilt versus null are reported. No other regions survived an uncorrected threshold of p = .005 (extent threshold of 4 voxels) and a voxel- or cluster-level p = .05 over the whole brain or our a priori ROIs. ∗Survived voxel-wise FWE-correction over tier 1 ROI; ∗∗Survived voxel-wise FWE-correction over tier 2 ROI. S_AG = self-agency condition, O_AG = other-agency condition, between-subject covariates in all models were group (MDD/control), the main effects of conceptual (CONCEPT) and valence (VALENCE) difference scores (S_AG – O_AG), and their interaction score (VALENCE × CONCEPT).
