搜索任务中基于听觉工作记忆的注意捕获

Attention Capture Based on Auditory Working Memory in Search Task

摘要: 采用双任务范式，要求被试在保持听觉工作记忆内容的同时完成听觉搜索任务。结果发现，当搜索序列出现与工作记忆内容相同的干扰物(即匹配条件)，且匹配干扰物出现在目标之前时，其搜索时间比中性条件下目标出现在同等位置的搜索时间更长。研究表明与视觉工作记忆一样，听觉工作记忆在搜索任务中同样能诱发注意捕获，并为今后此领域听觉通道的研究提供了可用的实验材料和参数。

Abstract: The present study adopts dual-task paradigm, which asks subjects to do the auditory search task while maintaining the contents in auditory working memory. It is found that compared to neutral trails in which distractors are irrelevant to the working memory item, in exact-matching trials in which the working memory item reappears as one of the distractors, search time is longer only on the condition that the memory-matching distractor appears before the target in the search array. The present study proves that auditory working memory can also guide attention automatically in the search task, and provides experiment materials and parameters for reference for future study in this field.
