DMN-FPCN	0.147	0.067	0.002	0.026

Each model included crossed random effects for participants and a fixed effect for neural similarity, with social network proximity as the outcome variable. P values and SEs were adjusted to account for data redundancy (Materials and Methods). Only significant associations are shown. AN, auditory network; CN, cerebellar network; COCN, cingulo-opercular task control network; DMN, default mode network; DAN, dorsal attention network; FPCN, frontoparietal task control network; SAN, salience network; SMHN, somatosensory motor-hand network; SMMN, somatosensory motor-mouth network; VAN, ventral attention network.
