Table 1. Clusters where FA and interpersonal competence correlated significantly.

Clusters where FA and interpersonal competence were significantly correlated (p<0.05). Larger clusters have smaller numbers (1-12). The column “size (voxels)” indicates how many voxels are contained in each cluster. The column “corrected p-value” refers to the p-value associated with the maximum “intensity” voxel within the cluster after correction for multiple comparisons using Threshold-Free Cluster Enhancement (TFCE). The columns “X” “Y” and “Z” indicate the MNI coordinates of the maximum intensity voxel in each cluster; coordinates are expressed in standard space (mm). The last column reports the WM (white matter) labels taken from the JHU white-matter tractography atlas. According to the atlas, the clusters contain voxels belonging to six WM tracts: Uncinate Fasciculus (UF), Cingulum (CM), Forceps Major (FMa), Inferior Fronto Occipital Fasciculus (IFOF), Inferior Longitudinal Fasciculus (ILF), and Superior Longitudinal Fasciculus (SLF).
