适应不良行为的人格测量通常针对冲动的概念，冲动泛指快速且考虑不周的行为。然而，冲动行为的根本原因尚不清楚，并且存在许多相互矛盾的结果。有人认为，冲动源于抑制性失调，这是一种通过行为测量来评估的神经心理学概念。我们对正常成年人（n = 31；年龄范围：19-51）中常见的冲动性自我报告测量（巴勒特冲动量表）与抑制控制的四种行为范式（运动抑制、停止信号、Stroop 和负启动）之间的关联进行了初步调查。斯特鲁普冲突与无计划、注意力、运动和整体自我报告的冲动显着相关。运动去抑制与非计划冲动显着相关；反应变异性与运动冲动有关。因此，有证据表明，在正常成年人中，冲动与抑制性失调的某些特定措施有关。 (c) 2006 Elsevier Ltd. 保留所有权利。
Personality measures of maladaptive behavior often target the notion of impulsivity, which broadly refers to rapid and ill-considered conduct. The underlying cause of impulsive behavior, however, is not well understood, and there are many conflicting results. It has been suggested that impulsivity arises from inhibitory dyscontrol, a neuropsychological notion that is assessed via behavioral measures. We conducted a preliminary investigation of the association between a common self-report measure of impulsivity, the Barratt Impulsiveness Scale, and four behavioral paradigms of inhibitory control (motor inhibition, stop signal, Stroop, and negative priming) in normal adults (n = 31; age range: 19-51). Stroop conflict correlated significantly with non-planning, attentional, motor, and overall self-reported impulsiveness; motor disinhibition correlated significantly with non-planning impulsiveness; and response variability was associated with motor impulsiveness. Thus, there is evidence to suggest that, among normal adults, impulsivity is associated with some specific measures of inhibitory dyscontrol. (c) 2006 Elsevier Ltd. All rights reserved.
