我们提出了一个由四个工作记忆任务组成的电池，这些任务是使用MATLAB和免费的心理物理工具箱实现的。该程序包包括R和SPSS中的预处理脚本，以便于数据分析。这四项任务包括句子广度任务、操作广度任务、空间短时记忆测试和记忆更新任务。选择这些任务是为了提供一套不同类型的工作记忆容量测量，从而减少方法差异，并利用工作记忆的两个内容领域(语言，包括数字，与空间)及其两个功能方面(加工背景下的存储和关系整合)。这一任务组合在三个实验中得到了验证，这些实验用两种语言(英语和汉语)进行，涉及350多名参与者。在所有情况下，任务都被发现加载在一个潜在变量上。在进一步的实验中，潜在的工作记忆变量被发现与流体智力的瑞文矩阵测试的表现高度相关，但并不完全相关。我们认为，无论是说英语还是说中文的参与者，该电池都是一种评估工作记忆容量的通用工具。电池可以从www.cogsorwa.com(“软件”按钮)下载。
We present a battery of four working memory tasks that are implemented using MATLAB and the free Psychophysics Toolbox. The package includes preprocessing scripts in R and SPSS to facilitate data analysis. The four tasks consist of a sentence-span task, an operation-span task, a spatial short-term memory test, and a memory updating task. These tasks were chosen in order to provide a heterogeneous set of measures of working memory capacity, thus reducing method variance and tapping into two content domains of working memory (verbal, including numerical, vs. spatial) and two of its functional aspects (storage in the context of processing and relational integration). The task battery was validated in three experiments conducted in two languages (English and Chinese), involving more than 350 participants. In all cases, the tasks were found to load on a single latent variable. In a further experiment, the latent working memory variable was found to correlate highly but not perfectly with performance on Raven's matrices test of fluid intelligence. We suggest that the battery constitutes a versatile tool to assess working memory capacity with either English- or Chinese-speaking participants.
