A brain-based neural model of attention is used to simulate results for the 'attentional blink', observed when a subject is exposed to a rapid stream of stimuli and required to monitor for two successive targets in the stream. The 'blink' occurs when the time between the first and second targets is 200-500 ms, when there is reduced accuracy for report of the second target. The model gives a qualitative explanation of the phenomenon, especially of how attention is bolstered, during the processing to report of a given stimulus, in order to defend reportable information from attack by distracters.
一种基于大脑的注意力神经模型被用于模拟“注意瞬脱”的结果。当受试者暴露于快速的刺激流中，并被要求监测该流中的两个连续目标时，会观察到这种现象。当第一个目标和第二个目标之间的时间间隔为200 - 500毫秒时，就会出现“瞬脱”，此时对第二个目标的报告准确性会降低。该模型对这一现象给出了定性解释，特别是解释了在处理给定刺激的报告过程中，注意力是如何得到加强的，以便保护可报告信息免受干扰因素的影响。
