上海体育大学陈安涛研究组完成对压力导致的错误认知和错误后调整障碍的神经和行为测量。相关论文于2023年12月9日在线发表在《神经科学通报》杂志上。

研究人员考察了急性应激后错误认知和错误后调整的时间动态。49名健康男性被随机分配到对照组（26人）或压力组（23人）。压力诱导后，参与者完成错误认知任务，并通过脑电图评估他们的大脑活动。与对照组相比，应激组的错误意识准确率较低，意识到错误后的Pe（错误正向性）和ΔPe振幅较小，这表明应激后错误意识受损。

此外，应激组在意识到错误后做出反应的准确率低于未意识到错误后做出反应的准确率和对照组，这表明应激后的错误调整能力较差。这些研究结果表明，压力会影响错误处理的连续阶段。压力会导致错误识别能力受损，从而进一步产生适应不良的错误后表现。

据悉，压力会对错误处理产生负面影响，但压力对错误认知的影响仍有待确定。

Abstract: Exposure to stress negatively affects error processing, but the impact of stress on error awareness remains to be determined. In the present study, we examined the temporal dynamics of error awareness and post-error adjustment following acute stress. Forty-nine healthy men were randomly assigned to the control (n = 26) or stress group (n = 23). After stress induction, participants completed the error awareness task, and their brain activity was assessed by electroencephalography. Compared to the control group, the stress group demonstrated lower error awareness accuracy and smaller Pe (error positivity) and ΔPe amplitudes following aware error responses, which indicated impairment of error awareness following stress. Furthermore, the stress group had lower accuracy in post-aware error responses than in post-unaware error responses and the control group, which indicated poor post-error adjustment following stress. Our results showed a stress effect on sequential stages of error processing. Stress induces impaired error identification, which further generates maladaptive post-error performance.
