Focus switching in working memory involves accessing an object in the focus of attention in order to retrieve its content. Objects in working memory can be viewed as consisting of two types of information: contents (e.g., numerical information) and contexts (e.g., cues to retrieve the contents). This study examined the extent to which content retrieval and context access may be separated. Three experiments were carried out in which object switching and content retrieval were manipulated. In addition, the alternation between the retrieval operations was also manipulated. The main result was that content retrieval required time over and above that needed to access the object. This finding supports the idea that contexts and their contents may be accessed independently when an object is brought into the focus.
工作记忆中的焦点切换涉及访问注意力焦点中的一个对象，以便检索其内容。工作记忆中的对象可以被视为由两种类型的信息组成：内容（例如，数字信息）和上下文（例如，用于检索内容的线索）。本研究考察了内容检索和上下文访问在多大程度上可以分离。进行了三项实验，其中对对象切换和内容检索进行了操纵。此外，还对检索操作之间的交替进行了操纵。主要结果是，内容检索所需的时间超过了访问对象所需的时间。这一发现支持了这样一种观点，即当一个对象进入焦点时，上下文及其内容可以独立访问。
