The maintenance of serial order information is a core component of working memory (WM). Many theoretical models assume the existence of specific serial order mechanisms. Those are considered to be independent from the linguistic system supporting maintenance of item information. This is based on studies showing that psycholinguistic factors strongly affect the ability to maintain item information, while leaving order recall relatively unaffected. Recent language-based accounts suggest, however, that the linguistic system could provide mechanisms that are sufficient for serial order maintenance. A strong version of these accounts postulates serial order maintenance as emerging from the pattern of activation occurring in the linguistic system. In the present study, we tested this assumption via a computational modeling approach by implementing a purely activation-based architecture. We tested this architecture against several experiments involving the manipulation of semantic relatedness, a psycholinguistic variable that has been shown to interact with serial order processing in a complex manner. We show that this activation-based architecture struggles to account for interactions between semantic knowledge and serial order processing. This study fails to support activated long-term memory as an exclusive mechanism supporting serial order maintenance.

串行订单信息的维护是工作记忆（WM）的核心组成部分。许多理论模型假设存在特定的序列顺序机制。这些被认为独立于支持项目信息维护的语言系统。这是基于研究表明，心理语言学因素强烈影响维护项目信息的能力，同时使订单回忆相对不受影响。然而，最近基于语言的描述表明，语言系统可以提供足以维持序列秩序的机制。这些叙述的一个强有力的版本假设序列顺序维护是从语言系统中发生的激活模式中出现的。在目前的研究中，我们通过实施一个纯粹基于激活的架构，通过计算建模方法测试了这个假设。我们针对涉及语义相关性操纵的几个实验测试了该架构，语义相关性是一种心理语言学变量，已被证明可以以复杂的方式与串行订单处理进行交互。我们表明，这种基于激活的架构难以解释语义知识和串行订单处理之间的交互。这项研究不支持激活的长期记忆作为支持串行顺序维护的排他性机制。我们表明，这种基于激活的架构难以解释语义知识和串行订单处理之间的交互。这项研究不支持激活的长期记忆作为支持串行顺序维护的排他性机制。我们表明，这种基于激活的架构难以解释语义知识和串行订单处理之间的交互。这项研究不支持激活的长期记忆作为支持串行顺序维护的排他性机制。
