Covariate results from the connectivity regressions in the 58-child fMRI subset: SES was significant for left insula/IFG (p = .019), left SMG (p = .008), and right SMG (p = .025), but no regressor was significant for the ACC connection.

"The direction of the effect was such that greater right hemisphere connectivity was observed in children from low compared to high SES backgrounds."
