Abstract

Objective: Research about the impact of acute stress on inhibitory control remains a contentious topic, with no consensus reached thus far. This study aims to investigate the effects of acute stress on an individual's inhibitory control abilities and to elucidate the underlying neural mechanisms by analyzing resting state electroencephalogram (EEG) data.

Methods: We recruited 32 male college students through participant recruitment information to undergo within-subject experiments under stress and non-stress conditions. Physiological indicators (cortisol and heart rate), self-report questionnaires, and behavioral data from the Stroop task were collected before, during, and after the experiment. Additionally, a five-minute eyes closed resting state EEG data collection was conducted during the Stroop task before.

Results: (1) Acute stress led to a reduction in the conflict effect during the participants' Stroop task in individuals. (2) Stress resulted in an increase in the power of the beta in the resting state EEG. (3) Acute stress caused an increase in the duration of class D and an increase in the transition probabilities from classes C and B to class D in the microstates of the resting state EEG. (4) Acute stress leads to an increase in beta power values in individuals' resting state EEGs, which is significantly negatively correlated with the reduction of the conflict effect in the Stroop task under stress.

Conclusions: Acute stress can enhance individuals' attentional level, thereby promoting inhibitory control performance.

脑电图证明急性压力可通过提高注意力来增强抑制控制。

研究目的关于急性应激对抑制控制能力的影响的研究仍然是一个有争议的话题，迄今为止尚未达成共识。本研究旨在通过分析静息状态脑电图（EEG）数据，探讨急性应激对个体抑制控制能力的影响，并阐明其背后的神经机制：我们通过参与者招募信息招募了 32 名男性大学生，在应激和非应激条件下进行受试者内实验。我们在实验前、实验中和实验后收集了生理指标（皮质醇和心率）、自我报告问卷和来自 Stroop 任务的行为数据。结果：（1）急性压力导致个体在执行 Stroop 任务时的冲突效应降低。(2）压力导致静息状态脑电图中的β功率增加。(3) 急性应激导致静息状态脑电图微状态中 D 类持续时间增加，以及从 C 类和 B 类过渡到 D 类的概率增加。(4）急性应激导致个体静息状态脑电图中β功率值的增加，这与应激状态下Stroop任务中冲突效应的减少呈显著负相关：结论：急性应激可提高个体的注意水平，从而促进抑制性控制的表现。

期刊介绍： Brain Sciences (ISSN 2076-3425) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications in the areas of cognitive neuroscience, developmental neuroscience, molecular and cellular neuroscience, neural engineering, neuroimaging, neurolinguistics, neuropathy, systems neuroscience, and theoretical and computational neuroscience. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
