冲动的人会做出冒险的选择，他们的动机更多的是眼前的回报，而不是潜在的长期负面后果。我们使用事件相关电位研究奖励和惩罚的冲动敏感性的影响，在两张卡的选择任务中的高和低冲动的14个大学生群体形成的Barratt冲动量表得分的中位数分裂的风险决策。当做出低风险选择时，高冲动者的P3较大，低冲动者的P3较小，这表明高风险选择是高冲动者的默认选择，低风险选择是低冲动者的默认选择。低冲动者（而非高冲动者）在做出高风险选择后有更大的错误相关负性，这表明低冲动者将高风险选择评估为糟糕的决定。结果表明，高冲动个体在期权评估中偏向于即时回报，但对选择的负面后果不太敏感。
Impulsive individuals make risky choices, motivated more by immediate reward than potential long-term negative consequences. We used event-related potentials to study the impact of reward and punishment sensitivity in impulsivity on risky decision-making in a two-card choice task in groups of 14 high and 14 low impulsive undergraduates formed by a median split on the Barratt Impulsiveness Scale score. The high impulsives had a larger P3 and the low impulsives a smaller P3 to the cards when making a low-risk choice suggesting that the high-risk option was the default choice of the high impulsives and the low-risk choice the default for the low impulsives. The low, but not the high impulsives had a larger error-related negativity following high-risk choice indicating that the low impulsives evaluated the risky choice as a poor decision. The results indicate that high impulsive individuals are biased towards immediate reward during option evaluation but are less sensitive to the negative consequences of their choices.
