许多先前的研究已经表明，视觉搜索通常是由一个独特的“单体”干扰搜索显示的存在中断。在这里，我们展示了这种关注。在形状搜索过程中，不相关的颜色单体的捕获关键取决于搜索任务的工作记忆的可用性：当工作记忆加载在一个并发但不相关的口头短期记忆任务中时，捕获增加。这些研究结果与先前的研究结果一致，即增加工作记忆负荷会导致Stroop类任务中更大的干扰物干扰（de Fockert，Rees，Frith，& Lavie，2001; Lavie，Hirst，de Fockert，& Viding，2004），这支持了工作记忆提供目标导向的视觉选择性注意控制的假设，允许最大限度地减少目标无关干扰物的干扰。
Much previous research has demonstrated that visual search is typically disrupted by the presence of a unique "singleton" distractor in the search display. Here we show that attentional. capture by an irrelevant color singleton during shape search critically depends on availability of working memory to the search task: When working memory is loaded in a concurrent yet unrelated verbal short-term memory task, capture increases. These findings converge with previous demonstrations that increasing working memory load results in greater distractor interference in Stroop-like tasks (de Fockert, Rees, Frith, & Lavie, 2001; Lavie, Hirst, de Fockert, & Viding, 2004), which support the hypothesis that working memory provides goal-directed control of visual selective attention allowing to minimize interference by goal-irrelevant distractors.
