Interaction of (Caregiver vs. Stranger) versus (Social vs. Nonsocial). Contrast was defined as (Caregiver Social—Caregiver Nonsocial)—(Stranger Social—Stranger Nonsocial). Hypothalamus activation was found for the target contrast, t = 5.68, P = 0.00007, cluster size = 27 mm3 or 8 voxels, surviving P < 0.05 FWE small volume correction using the hypothalamus anatomical mask. Additionally, a VOI analysis for the hypothalamus revealed a significant effect for the target contrast t = 1.83, P < 0.0473.
