注意捕获现象在空间搜索任务中得到了典型的研究。道尔顿和Lavie（2004）最近证明，听觉注意也可以被快速呈现的音调序列中的单个项目捕获。在这里报道的实验中，我们调查了这些发现是否跨模态扩展到使用视听刺激的顺序搜索任务。参与者搜索在特定维度上定义的目标的中央呈现的视听刺激流（例如，在特定的模式下。在存在与不存在一个独特的单分散的任务性能进行了比较。不相关的听觉单体捕获注意力在视觉搜索任务，导致干扰时，他们正好与干扰，但促进时，他们正好与目标。这些结果表明，在非空间视觉搜索过程中的注意捕获听觉单例。
The phenomenon of attentional capture has typically been studied in spatial search tasks. Dalton and Lavie (2004) recently demonstrated that auditory attention can also be captured by a singleton item in a rapidly presented tone sequence. In the experiments reported here, we investigated whether these findings extend cross-modally to sequential search tasks using audiovisual stimuli. Participants searched a stream of centrally presented audiovisual stimuli for targets defined on a particular dimension (e.g., duration) in a particular modality. Task performance was compared in the presence versus absence of a unique singleton distractor. Irrelevant auditory singletons captured attention during visual search tasks, leading to interference when they coincided with distractors but to facilitation when they coincided with targets. These results demonstrate attentional capture by auditory singletons during nonspatial visual search.
