Response Perseveration, Inhibitory Control, and Central Dopaminergic Activity in Childhood Behavior Disorders

Abstract

We screened students (N = 710) in grades four through six at two public elementary schools for behavior problems, using the Revised Behavior Problem Checklist. Five groups of children were identified: Conduct disorder (n = 8), attention deficit disorder (n = 9), conduct disorder plus attention deficit disorder with hyperactivity (? = 11), anxiety-withdrawal (n = 12), and normal control (? = 15). A response perseveration task, inhibitory control task, and a noninvasive measure of dopaminergic activity were administered to selected students, and group differences were predicted based on Quay’s hypotheses as derived from Gray’s theory of brain function. Hypothesized group differences were not found, although analyses revealed dimensional relationships that were consistent with the hypotheses. Results are discussed in terms of Quay’s hypotheses and potential modifications to tasks for future research. © 1993 Taylor & Francis Group, LLC.
