采用事件相关脑电位（ERPs）研究了Stroop任务中支持执行的神经活动的时间过程。观察到四个空间和时间上不同的调制区分ERPs引起的一致性，中性，或单词识别试验引起的不一致的试验。其中两个调制反映了增加的负性在额中央区和正面的额极区不一致的审判，并可能反映冲突检测和解决过程。其他调制，分布在左顶叶和颞顶叶区域，可能反映了活动的意义为基础的概念水平系统活跃在一致的，中性的，和单词识别试验;和活动的知觉水平系统支持任务的性能时，只有颜色信息可以引导一个有效的反应不一致的试验。(C)1999 Elsevier Science B. V.保留所有权利。
The time course of neural activity supporting performance during the Stroop task was investigated using event-related brain potentials (ERPs). Four spatially and temporally distinct modulations were observed differentiating the ERPs elicited by incongruent trials from the ERPs elicited by congruent, neutral, or word identification trials. Two of these modulations reflected increased negativity over the fronto-central region and positivity over the fronto-polar region for incongruent trials and may reflect conflict detection and resolution processes. The other modulations, distributed over the left parietal and temporo-parietal regions, may reflect the activity of a meaning-based conceptual level system active during congruent, neutral, and word identification trials; and the activity of a perceptual level system supporting task performance when only color information can guide an efficient response on incongruent trials.
