Abstract

Students ($N$ = 710) in grades 4 through 6 at two public elementary schools were screened 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 ($n$ = 11), Anxiety-Withdrawal ($n$ = 12), and normal control ($n$ = 15). A response perseveration task (Daugherty & Quay, 1989), an inhibitory control task (Schachar & Logan, 1988), and a noninvasive measure of dopaminergic activity (Karson, 1983) were administered to selected students, and group differences were predicted based on Quay's (1988a, 1988b, 1988c) hypotheses as derived from Gray's (1987) theory of brain function. Hypothesized group differences were not found, although exploratory analyses revealed some relationships which are consistent with the hypotheses.
