| 摘 要： | 以往研究显示,知觉组织影响时序知觉,采用ERP技术拟探讨知觉组织影响时序知觉的认知机制。采集23名被试完成同时判断任务的脑电数据。行为结果发现,知觉组织影响时序知觉,具体表现为知觉组织条件的同时判断频率显著高于非知觉组织条件。ERPs结果发现,在P1和P2成分上,知觉组织条件与非知觉组织条件引发的波幅没有显著差异; 而在N1成分上,知觉组织条件诱发的N1波幅显著大于非知觉组织条件。这表明,知觉组织对时序知觉的影响可能发生在视觉刺激加工的早期阶段,视觉刺激的知觉组织先于时序信息加工。

| Abstract: | Previous studies have shown that perceptual grouping influences temporal order perception.This study aims to explore the cognitive mechanism of the effect of perceptual grouping on temporal order perception.ERP technology was used to collect EEG data of 23 subjects who completed the simultaneity judgment task.The results showed that there was no significant difference between perceptual grouping condition and non-perceptual grouping condition in P1 and P2 amplitudes,but we found larger N1 amplitudes elicited by perceptual grouping condition compared with non-perceptual grouping condition,which presumably reflects the effect of perceptual grouping on temporal order perception may be occur in the early stage of visual stimulus processing,and the perceptual grouping of visual stimulus precedes temporal order information processing. |
