Neighborhood poverty during childhood moderates the association between age and functional brain network architecture across adolescence. A-B) Age is positively associated with the principal component of network segregation (Panel A) and network balance (Panel B) at high and mean, but not low, levels of neighborhood poverty. Interaction effects are significant within regions shaded in gray, such that greater neighborhood poverty levels mainly predict lower network segregation and network balance in younger, but not older, youth. Plots were generated using the interactions package in R. For visualization purposes, only values of network segregation and network balance within two SD’s from the mean are depicted to illustrate the observed effects more clearly (Network Segregation: n = 9 above two SD’s from mean, n = 20 below two SD’s from mean; Network Balance: n = 14 above two SD’s from mean, n = 5 below two SD’s from mean). See Fig. S3 for the full, non-truncated figure.
