This study compared laboratory models of impulsive behavior in 60 women ages 18-40. Three groups (n = 20, each) were recruited: (1) normal controls, (2) women on probation/parole without childhood aggression (Fight-), and (3) women on probation/parole with childhood aggression (Fight+). Two types of impulsivity paradigms were compared: response-disinhibition/attentional [Immediate/Delayed Memory Task (IMT/DMT)] and delayed-reward [Single Key Impulsivity Paradigm (SKIP)] models. The Fight+ group performed more impulsively, responding with more commission errors (IMT/DMT) and shorter delay choices (SKIP) compared to either the Fight- or Control groups. Compared to the SKIP, the IMT and DMT tasks had larger effect sizes and a more orderly pattern of impulsive performance differences between groups. Women classified on the basis of childhood behavior (initiating physical aggression) are behaviorally distinct on laboratory measures of impulsiveness in adulthood.
