The debate about whether the capacity of working memory (WM) varies with the complexity of memory items continues. This study employed novel experimental materials to investigate the role of complexity in WM capacity. Across seven experiments, we explored the relationship between complexity and WM capacity. The results indicated that the complexity of memory items significantly affects WM capacity. However, given the non-linear relationship between complexity and WM capacity, we propose that WM may not allocate resources directly to each individual item. Instead, it might integrate these items to some extent before storage.
关于工作记忆（WM）的容量是否会随着记忆项目的复杂性而变化的争论仍在继续。本研究采用新颖的实验材料来探究复杂性在工作记忆容量中的作用。在七项实验中，我们探讨了复杂性与工作记忆容量之间的关系。结果表明，记忆项目的复杂性显著影响工作记忆容量。然而，鉴于复杂性与工作记忆容量之间的非线性关系，我们提出工作记忆可能不会直接将资源分配给每个单独的项目。相反，它可能在存储之前在一定程度上整合这些项目。
