panic disorder, PTSD, obsessive disorder, and compulsive disorder), 3 mood disorders (depression, dysthymia, and mania), and 2 externalizing disorders (conduct disorder and antisocial personality disorder). Lifetime symptom counts for all positive symptoms were obtained for each disorder, using the DSM-IV (American Psychiatric Association, 2000) symptom guidelines. The result of neuropsychological testing on a matched subset of the samples studied here was recently published (Smith and Fein, 2010) showing intact cognitive function in TNAD, with an unanticipated effect of better attention domain scores in TNAD, possibly reflecting compensatory attentional strategies in heavy drinking functional alcoholics. We examined the possible association between reduced ERP latencies reported below and attention domain scores. The attention domain score consisted of the average Z-score for the Stroop (Golden, 2002) Color condition, and the MicroCog (Powell et al., 1993) Numbers Forward, Numbers Reversed, Alphabet, and Word List 1 subtests.
