Abstract
Inhibitory control is an essential skill for multiple domains including academic
functioning and peer relationships. The current study assessed the effectiveness of an
attachment based parenting intervention (Attachment and Biobehavioral Catch-up),
implemented in infancy, on inhibitory control when the children were eight years of age.
Inhibitory control was measured among three populations - a high risk intervention
group, a high risk control group, and a low risk comparison group. One hundred and four
8-year-old children underwent behavioral and event-related potential (ERP) measures
during a forced-choice inhibitory control task - the Stop Signal Reaction Time Task
(SSRT). Children in the low risk comparison group performed better than the high risk
control group on behavioral indicators of inhibitory control. No significant differences
emerged between the high risk intervention group and the low risk comparison group or
the high risk control group. Children who did not receive the intervention performed
worse on the SSRT task then children in the low risk comparison group. No differences
were found in ERP amplitudes between groups.
