【摘要】背景：在视觉环境中检测和响应目标物体是目标导向行为的关键因素。慢性应激通常会导致前额叶皮层（PFC）功能的改变，这可能会影响依赖PFC的选择性注意过程。本研究旨在探讨慢性学业压力对注意力控制过程的影响。方法：应激组和对照组均进行基于箭头的Eriksen Flanker任务。在参与者执行任务时记录事件相关电位（ERP）。结果：行为结果显示，与对照组相比，应激组的Flanker RT效应降低，表明在压力下干扰减少。ERP结果显示，与对照组相比，应激组的额叶N2活动减少，但早期P3和晚期P3/LPC活动增加。这些结果表明，在压力下，冲突监控减少，但冲突解决过程增加。结论：慢性学业压力通过减少冲突监控和增强冲突解决过程来改善注意力控制。

[Abstract] Background: Detecting and responding to target objects in the visual environment is a key factor in goal-directed behavior. Exposure to chronic stress often results in alterations of prefrontal cortex (PFC) function, which may impact PFC-dependent selective attention process. This study aimed to investigate the effect of chronic academic stress on attentional control process. Method: Both the stress group and the control group performed an arrow-based version of the Eriksen Flanker task. Event-related potentials (ERP) were recorded while the participants performed the task. Results: The behavioural results exhibited decreased Flanker RT effect for the stress group compared to the control group, suggesting a reduced interference under stress. The ERP results showed that stress group showed decreased frontal N2 but increased early P3 and late P3/LPC activities compared to the control group. These results suggest reduced conflict monitoring but increased conflict resolution process under stress. Conclusions: The chronic academic stress improves attentional control by reducing the conflict monitoring and enhancing conflict resolution processes.
