Abstract：
Previous studies have shown that alertness is closely related to executive control function, but its impact on components of post-error adjustment is unknown. This study applied the Attentional Networks Test and the Four-choice Flanker task with three response stimulus intervals (RSIs) to explore the correlation between alertness and post-error adjustment. The linear mixed-effects model of alertness and RSI on the post-error processing indicators showed a significant negative correlation between the alertness and post-error slowing (PES) under 200 ms RSI , as well as between alertness and post-error improvement in accuracy (PIA) under both 700 ms RSI and 1200 ms RSI. Participants with lower alertness showed larger post-error slowing in the early stages, while those with higher alertness had smaller PIA in later stages. This study revealed the effects of alertness on different processing components of post-error adjustment. The control strategies utilized by individuals with high and low levels of alertness differed in preparation for performance monitoring. Alertness improved post-error response speed in a task-unspecific manner, but not post-error adaptation.
摘要：
先前的研究表明，警觉性与执行控制功能密切相关，但它对错误后调整部分的影响是未知的。本研究应用了注意网络测试和具有三个响应刺激间隔（RSIs）的四选择Flanker任务，以探索警觉性与错误后调整之间的相关性。警觉性和RSI对误差后处理指标的线性混合效应模型显示，200msRSI下的警觉性和误差后减慢（PES）与700msRSI和1200msRSI下的误差后精度提高（PIA）之间呈显着负相关。警觉性较低的参与者在早期阶段表现出较大的错误后放缓，而警觉性较高的人在后期的PIA较小。这项研究揭示了警觉性对错误后调整的不同处理组件的影响。具有高警觉性和低警觉性的个体所采用的控制策略在为绩效监测做准备时有所不同。警觉性以任务非特定的方式提高了错误后的响应速度，但不是错误后适应。
