两种类型的行为模型的冲动行为，反应-去抑制/注意力和奖励-选择反应模型，被用来比较妇女分组的高（冲动+，n=43）和低（冲动-，n = 43）自我报告的冲动行为的艾森克I-7问卷。四个不同的测试任务中有两个是反应去抑制/注意力模型;这些模型包括即时和延迟记忆任务和GoStop任务。另外两个任务是基于奖励选择模型的冲动，包括单关键冲动范式和两个选择奖励任务。特别感兴趣的是，是否委员会错误（反应去抑制/注意力范式）或偏好较小的更快的奖励比较大的更晚的奖励（奖励选择）将不同的群体之间。参与者在一天内完成了每项任务的一次会议。最重要的发现是，Impulse +组有：（1）升高的委托错误;（2）较低的刺激辨别力（目标和捕获刺激之间）;（3）对停止信号的反应抑制较差。在反应-去抑制/注意力任务上的反应区分了冲动组，而奖励-选择任务则没有。这些结果表明，报告更高水平的特质冲动性的女性的反应方式与以前研究冲动行为的研究一致。(C)2002爱思唯尔科技有限公司版权所有。
Two types of behavioral models of impulsive behavior, response-disinhibition/attentional and reward-choice response models, were used to compare women grouped by high (Impulse +, n=43) and low (Impulse-, n = 43) self-reported impulsive behavior on the Eysenck I-7 Questionnaire. Two of the four different tasks tested were response-disinhibition/attentional models; these included the Immediate and Delayed Memory Task and the GoStop Task. The other two tasks were based on the reward-choice model of impulsivity and included the Single Key Impulsivity Paradigm and the Two-Choice Reward Task. Of particular interest was whether commission errors (response-disinhibition/attentional paradigms) or a preference for smaller-sooner rewards over larger-later rewards (reward-choice) would differ between the groups. Participants completed one session of each task in a single day. The most significant findings were that the Impulse + group had: (1) elevated commission errors; (2) lower stimulus discriminability (between target and catch stimuli); and (3) poorer response inhibition to a stop signal. Responding on the response-disinhibition/attentional tasks distinguished between the impulsivity groups while the reward-choice tasks did not. These results demonstrate that women who report higher levels of trait impulsivity respond in a manner consistent with previous studies examining impulsive behavior. (C) 2002 Elsevier Science Ltd.
