Four experiments are reported that investigated visual event integration by using a variant of the missing element paradigm. Good performance on this task depends on whether two brief successive stimulus displays are perceived as (or integrated into) one single event. We replicated the classic finding of greater accuracy with shorter duration of the first stimulus and ruled out an attention-related account thereof. In a subsequent electrophysiological experiment we found that successful event integration increased the amplitude of the N1, N2, and late P3 components of the event-related potential and decreased early P3 amplitude. No effect on the P1 was observed. The results provided evidence for an early onset of event integration in time and demonstrated the existence of electrophysiological markers of episodic integration. The implications of these results are related to studies on feature-specific integration and early attentional processes.
报告了四项实验，这些实验通过使用缺失元素范式的变体来研究视觉事件整合。在这项任务中表现良好取决于两个短暂的连续刺激显示是否被感知为（或整合为）一个单一的事件。我们复制了第一个刺激持续时间越短精度越高的经典发现，并排除了与注意力相关的解释。在随后的一项电生理实验中，我们发现成功的事件整合增加了事件相关电位中 N1、N2 和晚期 P3 成分的振幅，并降低了早期 P3 振幅。观察到 P1 没有影响。这些结果为事件整合在时间上的早期发生提供了证据，并证明了情节整合的电生理标记的存在。这些结果的意义与关于特征特定整合和早期注意力过程的研究有关。
