Associations with target P3 amplitude from a visual oddball task (P3) and broad endorsement of externalizing behaviors (indexed via self-report of alcohol and cannabis use, and antisocial behavior) were assessed in participants of European (EA; <jats:italic>N<\/jats:italic> = 2851) and African ancestry (AA; <jats:italic>N<\/jats:italic> = 1402).
