摘　　要：快速系列视觉呈现成串刺激，若第二个目标刺激（T2）在第一个目标刺激（T1）呈现后200-500ms内呈现，被试对T2的报告准确率显著降低，这一现象被称为注意瞬脱（Attentional Blink，AB）。近来，研究者发现注意瞬脱现象存在明显的个体差异，大约有5％的个体不会出现AB。本文重点比较两类个体在行为结果、事件相关电位和功能核磁共振结果之间的差异。分析产生差异的原因，试图打破普通个体时间序列上的加工能局限。Quick series into a series of stimulating Visual rendering, if the second target stimulus （T2） at the first target stimulus （T I） in 200-500ms after, was tried on T2 reported significantly reduced accuracy, this phenomenon is called the at- tentional blink （Attentional Blink, AB）. Recently, researchers have found that there is an obvious phenomenon of attentional blink of individual differences, about 5% individual AB does not occur. This article focus on comparing the two types of individual results, differences between eventrelated potentials and functional magnetic resonance imaging results. Cause analysis of variance, trying to break the normal individual time series processing limitations.
