Note: Analyses controlled for sibling closeness, and percentage of related siblings and percentage of sisters in sibling collective. In addition, the parental closeness analysis controlled for peer closeness and the peer closeness analysis controlled for parental closeness. L and R refer to left and right hemispheres; k refers to the number of voxels in each significant cluster; t refers to peak activation level in each cluster; x, y and z refer to MNI coordinates. All regions are significant at P < 0.005. Regions that share the same superscript are part of the same cluster.
