Abstract

This study examined the neurobiology of maternal sensitivity to children's emotions among mothers involved with Child Protective Services (CPS) and low-risk comparison mothers (M(age) = 31.6 years). CPS-referred mothers participated in the Attachment and Biobehavioral Catch-up (ABC) intervention or a control intervention. Mothers' event-related potentials (ERPs) were measured while they categorized images of children with crying, laughing, and neutral expressions. CPS-referred ABC mothers (n = 19) and low-risk comparison mothers (n = 30) showed a larger enhancement of ERP responses for emotional faces relative to neutral faces than CPS-referred control mothers (n = 21). Additionally, the magnitude of ERP responses to emotional faces was associated with observed maternal sensitivity. Findings add to the understanding of the neurobiology of deficits in parenting and suggest that these deficits are changeable through a parenting intervention.

Left (P7) and right (P8) electrodes were selected for measuring the N170 in the time window from 140 –180 ms.

The Pz electrode was selected for measuring the late positive potential (LPP) in the time window from 300 – 650 ms.
