根据最近的几种方法，工作记忆被认为是由一个子集的表征范围内的积极处理和一个更大的集合最近激活，但非关注的表示。采用反应-信号速度-准确性权衡（SAT）和探针识别任务的复杂反应时变量来测量工作记忆中分类材料的提取。在SAT中，发现了两种不同的检索速度：最后研究类别中的项目的检索速度较快，而列表中其他类别的所有项目的检索速度较慢。这种提取速度的差异在反应时间分布的形状上是明显的。更快的检索速度为项目从最后一类被认为是反映了一个匹配过程中，识别探针是迅速相比，目前的内容的认识。(C)北京：科学出版社.
Following several recent approaches, working memory is argued to consist of a subset of representations that are within the scope of active processing and a larger set of recently activated, but non-attended representations. A response-signal speed-accuracy tradeoff (SAT) and comple mentary reaction time variant of a probe recognition task were used to measure the retrieval of categorized material from working memory. In SAT, two distinct retrieval speeds were found: A fast rate for items from the last studied category and a slower rate common to all items from other categories in the list. This difference in retrieval speed was evident in the shapes of the reaction time distributions. The faster retrieval speed for items from the last category is argued to reflect a matching process in which the recognition probe is rapidly compared to the current contents of awareness.
