Three experiments were designed to investigate the causes of the auditory attentional blink (AB). Experiments 1A and 1B revealed that there was a larger auditory AB when the target and the distractors were different in two attributes than when they were different in only one attribute. Experiments 2A and 2B showed that for pure-tone distractor sequences, there were small auditory AB deficits when both the target and the probe were different from the distractors in two attributes or in one attribute; however, for pulse distractor sequences, there was a large auditory AB when both the target and the probe were different from the distractors in one attribute, but not when they were different in two attributes. Experiments 3A and 3B revealed that regardless of the relationship of the target to the subsequent distractors, a large AB was generated if it was the first sound in a sequence. Moreover, only a very small AB was apparent when the distractors following the probe were replaced by silence. These results indicated that the auditory AB is affected by both the requirement of creating and consolidating a new object file for the target and the overwriting of the probe by the distractors following it.
设计了三个实验来探究听觉注意瞬脱（AB）的成因。实验1A和1B表明，当目标与干扰项在两个属性上不同时，听觉AB比仅在一个属性上不同时更大。实验2A和2B显示，对于纯音干扰序列，当目标和探测音在两个属性或一个属性上与干扰项不同时，听觉AB缺陷较小；然而，对于脉冲干扰序列，当目标和探测音在一个属性上与干扰项不同时，会出现较大的听觉AB，但在两个属性上不同时则不会。实验3A和3B表明，无论目标与后续干扰项的关系如何，如果它是序列中的第一个声音，就会产生较大的AB。此外，当探测音之后的干扰项被静音取代时，仅出现非常小的AB。这些结果表明，听觉AB受到为目标创建和巩固新客体文件的需求以及后续干扰项对探测音的覆盖的影响。
