Children's appraisals of interparental conflict predict event-related potential components

Interparental conflict and neural correlates of children's emotion processing were examined. Event-related potential (ERP) data were collected from 87 children (9-11 years old) with stimuli depicting interpersonal anger, happiness, and neutrality. Three ERP components were modulated by child-reported measures of conflict, reflecting a progression from early sensory attention to cognitive control to stimulus categorization. Negative conflict predicted larger N1 and N2 amplitudes on happy than on angry trials. Greater self-blame for conflict predicted larger N2 amplitudes across emotions and larger P3 amplitudes on angry than on neutral or happy trials. Results suggest conflict-related experiences shape processing of interpersonal emotion.
