“…DBDF-patients did emit higher rates of commiSSion errors than controls, although this difference was not statistically significant. These findings are consistent with previous research using self-report measures, which indicate that impulsivity is elevated among DBD patients (Daderman, 1999;Tranah et aI., 1998), especially among those with a history of fighting (Farrington et aI., 1990;Loeber et aI., 2000). Confirmation of these predicted group differences on the IMT/DMT supports the contention made in previous CPT literature (e.g., Dougherty, 1999;Dougherty, Bjork, et aI., 2000;Dougherty, Marsh, et aI., 2000;Dougherty, Moeller, et aI., 1999;Halperin et aI., 1988Halperin et aI., , 1991Marsh et aI., in press;Mathias, Dougherty, et aI., 2002;Smith, Kendrick, & Maben, 1992;Sostek et aI., 1980;Sykes et aI., 1973;Wohlberg & Kornetsky, 1973) that certain types of commission errors are related to patterns of observed impulsive behavior.…”
