在本研究中，我们使用停止信号范式来评估与冲动和冒险性格特征相关的抑制某些计划行为的能力。在第一种情况下，受试者在没有激励的情况下执行停止信号任务。在第二种情况下，受试者使用避免冲突的方法来完成相同的任务：反应速度快的人得到奖励，缺乏抑制的人受到惩罚。采用艾森克人格量表中的冲动性分量表对20名男性受试者进行初步测试。主要发现：(1)高冲动组未发现运动抑制缺陷；高冲动组和低冲动组的估计平均抑制过程反应时间相同；(2)冲突情境中存在激励会影响低冒险性被试的运动抑制，后者采取更谨慎的反应策略。(C) 2002 Elsevier Science Ltd.版权所有。
In this study we assess the ability to inhibit certain planned actions in relation to the impulsiveness and venturesomeness traits of personality using the stop-signal paradigm. In the first condition subjects performed the stop-signal task without incentives. In the second condition, subjects performed the same task using an approach-avoidance conflict situation: speed of response was rewarded and the lack of inhibition was punished. Twenty male subjects were selected after preliminary testing using the impulsivity subscale from the Eysenck Personality Inventory. The main findings were: (1) no deficit in motor inhibition was found for hi-h-impulsive subjects; estimated mean reaction times of inhibitory processes were the same for both high- and low-impulsive groups and (2) the presence of an incentive in the conflict situation affected motor inhibition for low venturesomeness subjects, who adopted a more cautiousness response strategy.
