The interplay among interparental conflict, children's emotional insecurity, neurophysiological correlates of processing interparental conflict cues, and externalizing symptoms.

Exposure to destructive interparental conflict consistently predicts children's externalizing symptoms. Research has identified children's emotional security as an explanatory mechanism underpinning this association, but little is known about the role of children's neurophysiology in this pathway. We aimed to address that gap using event-related potential (ERP) data from a sample of 86 children, ages 9-11 years.
