Recent evidence has indicated that performing a working memory task that loads executive working memory leads to less efficient visual search (Han & Kim, 2004). We explored the role that executive functioning plays in visual search by examining the pattern of eye movements while participants performed a search task with or without a secondary executive working memory task. Results indicate that executive functioning plays two roles in visual search: the identification of objects and the control of the disengagement of attention.
最近的证据表明，执行一项加载执行性工作记忆的工作记忆任务会导致视觉搜索效率降低（Han & Kim，2004）。我们通过检查参与者在执行或不执行次要执行性工作记忆任务的搜索任务时的眼动模式，探索了执行功能在视觉搜索中所起的作用。结果表明，执行功能在视觉搜索中扮演两个角色：物体识别和注意力脱离控制。
