视觉工作记忆在视觉搜索中的作用

The Role of Visual Working Memory in Visual Search

视觉工作记忆在视觉搜索中的作用远比偏向竞争模型所描述的要复杂，个体能根据当前任务要求灵活地利用工作记忆来引导注意选择。在系统回顾已有研究的基础上，从客体工作记忆、空间工作记忆和执行工作记忆3个方面探讨了视觉工作记忆在视觉搜索中的作用。根据近期的研究，文章在最后对视觉工作记忆在视觉搜索中的作用做了7点总结，并对已往研究中存在的若干问题给予了解释，指出未来应该从前瞻记忆和内隐记忆等角度对视觉搜索中所涉及的视觉记忆进行深入研究。

The role of visual working memory in visual search is more complex than that described by the biased-competition model. According to the demands of current tasks， the contents of visual working memory can be used flexibly to guide attentional selection in visual search. Based on the systematic review of recent studies， we discuss the role of visual working memory in visual search from following three aspects: object working memory & visual search， spatial working memory & visual search， and executive working memory & visual search. In the end of this paper， we draw seven conclusions on the role of visual working memory in visual search based on the recent studies， and give our specific explanations for several problems existing in recent studies. We also put forward some directions for future researches on visual memory involved in visual search. The role of such visual memory as prospective memory and implicit memory in visual search should be studied in depth.
