The phenomenon of attentional capture by a unique yet irrelevant singleton distractor has typically been studied in visual search. In this article, the authors examine whether a similar phenomenon occurs in the auditory domain. Participants searched sequences of sounds for targets defined by frequency, intensity, or duration. The presence of a singleton distractor that was unique on an irrelevant dimension (e.g., a low-frequency singleton in search for a target of high intensity) was associated with search costs in both detection and discrimination tasks. However, if the singleton feature coincided with the target item, search was facilitated. These results establish the phenomenon of auditory attentional capture.
独特但不相关的单一干扰项引起的注意捕获现象通常是在视觉搜索中进行研究的。在本文中，作者研究了类似的现象是否会在听觉领域出现。参与者在声音序列中搜索由频率、强度或持续时间定义的目标。在不相关维度上独特的单一干扰项（例如，在搜索高强度目标时出现的低频单一干扰项）的存在，在检测和辨别任务中均与搜索成本相关。然而，如果单一特征与目标项一致，则搜索会变得更容易。这些结果证实了听觉注意捕获现象。
