Although much research has been done to study the working memory structure in children in their first school years, the relation of cognitive constructs involved in this process remains uncertain. In particular, it is unclear whether working memory is a domain general construct that coordinates separate codes of verbal and visuospatial storage or whether it is a domain-specific construct with distinct resources of verbal and visuospatial information. This paper investigates the structure of working memory, by using the Working Memory Test Battery for Children (WMTB-C) and by doing confirmatory factor analyses (CFAs) on a sample of Portuguese children (n = 103) between 8 and 9 years of age. The results of the confirmatory factor analyses that provide the best fit of the data correspond to the model that includes Central Executive and Visuospatial Sketchpad in the same factor, co-varying with a Phonological Loop factor. Moreover, the traditional working memory tripartite structure--based on the Baddeley and Hitch Model--revealed good fit to the data.
尽管已经有很多研究致力于研究儿童在其最初几年的学校中的工作记忆结构，但涉及这一过程的认知结构之间的关系仍然不确定。特别是，工作记忆是协调言语和视觉空间存储的单独代码的领域通用结构，还是具有言语和视觉空间信息的不同资源的特定领域结构尚不清楚。本文通过使用儿童工作记忆测试电池（WMTB-C），并对 8 至 9 岁的葡萄牙儿童样本（n = 103）进行验证性因素分析（CFAs），研究了工作记忆的结构。提供数据最佳拟合的验证性因素分析的结果对应于包括中央执行和视觉空间草图的模型，与语音回路因子共同变化。此外，基于 Baddeley 和 Hitch 模型的传统工作记忆三分结构也很好地适用于数据。
