Event-related brain potentials were used to examine the neural correlates of the visual illusion effect in the Poggendorff illusion. In this study, there were three tasks, namely, illusion task 1, illusion task 2 (similar to the classical Poggendorff figures, where the two oblique lines in which individuals were prone to judge to be collinear, were not collinear in fact), and baseline task. Scalp event-related brain potential analysis revealed that (a) both illusion task 1 and illusion task 2 elicited a more negative event-related brain potential deflection (N400-600) than did baseline task, approximately 400 ms after onset of the stimuli, and (b) high-level cognitive control system is, through enhancing the influence of the context on identifying the relationships of the two oblique lines, involved in generating the Poggendorff illusion.
事件相关脑电位被用于研究波根多夫错觉中视觉错觉效应的神经关联。在本研究中，有三项任务，即错觉任务1、错觉任务2（类似于经典的波根多夫图形，其中个体容易判断为共线的两条斜线实际上并不共线）和基线任务。头皮事件相关脑电位分析表明：（a）错觉任务1和错觉任务2在刺激开始后约400毫秒时，比基线任务诱发了更负的事件相关脑电位偏转（N400 - 600）；（b）高级认知控制系统通过增强情境对识别两条斜线关系的影响，参与了波根多夫错觉的产生。
