Object file continuity and the auditory attentional blink.

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.
