感觉寻求被定义为对各种新奇、复杂和强烈刺激的强烈需求，并愿意为这种体验承担风险。一些理论认为，对风险带来的负面后果不敏感是寻求感觉行为的标志之一。在本研究中，我们通过记录事件相关电位（ERPs）来研究高、低感觉寻求者在执行Eriksen侧翼任务时错误加工的时间过程。尽管纠正试验的erp没有组间差异，但感觉寻求与钝化的错误相关负性（ERN）有关，这是女性特有的。此外，感觉寻求的不同子维度与神经网络振幅的关系也不同。这些发现表明，感觉寻求和错误处理之间的关系是性别特异性的。
Sensation seeking is defined by a strong need for varied, novel, complex, and intense stimulation, and a willingness to take risks for such experience. Several theories propose that the insensitivity to negative consequences incurred by risks is one of the hallmarks of sensation-seeking behaviors. In this study, we investigated the time course of error processing in sensation seeking by recording event-related potentials (ERPs) while high and low sensation seekers performed an Eriksen flanker task. Whereas there were no group differences in ERPs to correct trials, sensation seeking was associated with a blunted error-related negativity (ERN), which was female-specific. Further, different subdimensions of sensation seeking were related to ERN amplitude differently. These findings indicate that the relationship between sensation seeking and error processing is sex-specific.
