High-level sensation seeking (HSS) has been linked to a range of risky and unhealthy behavior; however, the neural mechanisms underlying such linkage remain unclear. In the present study, we used event-related potential (ERP) with a Balloon Analogue Risk Task (BART) to investigate how sensation seeking modulates brain responses to sequential decision-making with variable reward/loss outcome magnitudes. Behavior data showed that decision-making behavior was significantly affected by the large compared with the small magnitude of monetary outcome in the BART for individuals with low-level sensation seeking (LSS), but not for individuals with HSS. Similarly, HSS individuals displayed no changes in feedback-related negativity (FRN) in response to negative outcomes from decision-making with large or small reward/loss magnitudes, whereas LSS individuals showed greater FRN in response to decision-making with large loss magnitude than those with small loss magnitude. In addition, FRN amplitude differences correlated with decision-making behavior changes from small to large outcome magnitude for LSS, while such correlation was not observed for HSS. These findings suggest that a high-level of sensation seeking is associated with behavioral and neural insensitivity to increased negative outcome during decision-making under uncertainty, which may lead to greater risky behavior in these individuals when facing potential loss.

在不确定情况下,高感觉寻求与行为和神经不敏感有关在决策过程中增加负面结果有关。

寻求高级感官(HSS)与一系列危险和不健康的行为有关;然而,这种联系的神经机制仍不清楚。在本研究中,我们将事件相关电位(ERP)与气球模拟风险任务(BART)结合使用,以研究寻求感觉的方式如何调节具有可变奖励/损失结果幅度的顺序决策的大脑反应。行为数据显示,对于具有低水平感官寻求(LSS)的个人,BART的金钱成果量较大,而与较小程度的金钱成果相比,决策行为受到显着影响,而对于HSS的个人,则没有。同样,HSS个体在奖励/损失幅度不大的情况下,对决策产生的负面结果没有表现出与反馈相关的否定性(FRN)的变化,而LSS个人对损失量大的决策的反应显示出更高的FRN。另外,对于LSS,FRN幅度差异与决策行为的变化从小到大的结果幅度相关,而HSS则没有观察到这种相关性。这些发现表明,高水平的寻求感觉与不确定性下决策过程中负面结果增加的行为和神经不敏感性有关,当面对潜在的损失时,这可能导致这些人的风险行为增加。而HSS没有观察到这种相关性。这些发现表明,高水平的寻求感觉与不确定性下决策过程中负面结果增加的行为和神经不敏感性有关,当面对潜在的损失时,这可能导致这些人的风险行为增加。而HSS没有观察到这种相关性。这些发现表明,高水平的寻求感觉与不确定性下决策过程中负面结果增加的行为和神经不敏感性有关,当面对潜在的损失时,这可能导致这些人的风险行为增加。
