The cortisol awakening response (CAR) is thought to provide an energetic “boost” for the coming day and has been shown to be associated with prefrontal dependent function. The aim of the current study was to examine the relationship between the CAR and same-day neural activity following an error response task. Forty-six healthy males (22.25 years ± 1.98) collected saliva samples at 0, 30 and 45 min post-awakening to measure the CAR, and on the same afternoon event-related potential activity during error processing was measured. Although no association was observed between CAR and post-error behavior, a significant quadratic relationship was observed between CAR and Error-related Negativity (ERN) amplitude, and this association remained while controlling for confounding factors. This finding suggested the existence of an inverted U-shaped relationship between CAR and the same-day error-monitoring function in healthy males.

健康男性皮质醇觉醒反应与当日误差监测功能之间呈倒U型关系

皮质醇觉醒反应(CAR)被认为为来临的一天提供了一个充满活力的“助推器”,并且已被证明与前额叶依赖性功能有关。当前研究的目的是检查错误响应任务后CAR与当日神经活动之间的关系。46名健康男性(22.25岁±1.98)在醒后0、30和45分钟收集唾液样本以测量CAR,并在同一下午测量错误处理期间与事件相关的潜在活动。尽管未观察到CAR与错误后行为之间的关联,但是在CAR与错误相关的负性(ERN)幅度之间观察到显着的二次关系,并且在控制混杂因素时仍保持这种关联。
