工作记忆中的注意焦点转换

Focus of Attention’s Switch in Working Memory

在工作记忆中的选择性注意及注意焦点机制的基础上，从3个方面回顾了对工作记忆中注意焦点转换的研究：(1)工作记忆中的注意焦点转换的概念及其基本研究方法；(2)影响注意焦点转换代价的因素，包括提取、复述、加工、更新和记忆集大小等；(3)注意焦点转换与工作记忆各功能成分之间的关系，包括注意焦点转换与工作记忆执行功能的关系，注意焦点转换反映的存储、加工和执行功能之间的相互关系，注意焦点转换与工作记忆中资源分配的关系。最后，该文展望了未来的研究方向。

Based on the mechanisms of selective attention and the focus of attention (FOA) in working memory， this article reviews 3 aspects regarding the switching of FOA in working memory： Firstly， the concept of switching of FOA in working memory and its basic research methods. Secondly， the cognitive factors which might affect the focus switch costs， mainly including retrieval， rehearsal， processing， update of memory and size of memory set， etc. Thirdly， the relation between FOA switching and the functions of working memory， including the relation between FOA switching and the executive functions of working memory， the relations between storage， processing and the executive functions of working memory which are all reflected through FOA switching， the relation between FOA switching and the distributing of resource in working memory. Finally the directions for future research are prospected.
