奖励是帮助生存的学习协会的组成部分。反馈负性（FN）是一种事件相关电位，它区分了金钱损失与收益的结果，最近出现了一种可能的奖励处理的神经测量。如果这个观点是正确的，那么FN应该与其他领域的奖励敏感性指标相关，尽管很少有研究调查这个问题。在目前的研究中，46名参与者完成了奖励反应性的自我报告测量，产生奖励敏感性行为测量的信号检测任务，以及引发FN的赌博任务。与FN反映奖励相关神经活动的观点一致，较大的FN与奖励敏感性的行为和自我报告措施增加相关。
Rewards are integral to learning associations that aid in survival. The feedback negativity (FN), an event-related potential that differentiates outcomes indicating monetary losses versus gains, has recently emerged as a possible neural measure of reward processing. If this view is correct, then the FN should correlate with measures of reward sensitivity in other domains, although few studies have investigated this question. In the current study, 46 participants completed a self-report measure of reward responsiveness, a signal detection task that generated a behavioral measure of reward sensitivity, and a gambling task that elicited an FN. Consistent with the view that the FN reflects reward-related neural activity, a larger FN correlated with increased behavioral and self-report measures of sensitivity to reward.
