Arousal evoked by detecting a performance error may provide a mechanism by which error detection leads to either adaptive or maladaptive changes in attention and performance. By pairing EEG data acquisition with simultaneous measurements of pupil diameter, which is thought to reflect norepinephrinergic arousal, this study tested whether transient changes in EEG oscillations in the alpha frequency range (8–12 Hz) following performance mistakes may reflect error‐evoked arousal. In the inter‐trial interval following performance mistakes (approximately 8% of trials), pupil diameter increased and EEG alpha power decreased, compared to the inter‐trial interval following correct responses. Moreover when trials were binned based on pupil diameter on a within‐subjects basis, trials with greater pupil diameter were associated with lower EEG alpha power during the inter‐trial interval. This pattern of association suggests that error‐related alpha suppression, like pupil dilation, reflects arousal in response to error commission. Errors were also followed by worse next‐trial performance, implying that error‐evoked arousal may not always be beneficial for adaptive control.

在快速执行任务时同时出现脑电图和瞳孔证据，以证明发生错误后的觉醒

通过检测性能错误引起的兴奋可以提供一种机制，通过该机制错误检测会导致注意力和性能的适应性或适应性改变。通过将EEG数据采集与瞳孔直径的同步测量（被认为反映了去甲肾上腺素能唤醒）相结合，这项研究测试了由于性能错误导致的EEG振荡在α频率范围（8–12 Hz）中的瞬态变化是否可能反映了诱发误差。与正确反应后的试验间隔相比，在表现错误后的试验间隔（约占试验的8％），瞳孔直径增加，脑电图alpha功率降低。此外，当根据受试者的瞳孔直径对试验进行分类时，在试验间隔期间，瞳孔直径较大的试验与较低的EEGα功率有关。这种关联模式表明，与错误相关的alpha抑制（如瞳孔扩大）反映了对错误委托的反应。错误之后还会出现较差的下一审性能，这表明由错误引起的唤醒可能并不总是对自适应控制有利。
