提出了工作记忆容量限制理解的理论。该理论提出，处理和存储都是由激活介导的，并且工作记忆中可用的激活总量因人而异。语言工作记忆能力的个体差异可以解释大学生在语言理解的几个方面的质和量差异。一方面是句法模块化：某些个体的较大容量允许句法和语用信息之间的交互，因此他们的句法过程不会被信息封装。另一方面是句法歧义：一些人的较大能力允许他们维持多种解释。该理论被实例化为一个生产系统模型，其中模型可用的激活量会影响它如何适应理解过程中发生的瞬态计算和存储需求。
A theory of the way working memory capacity constrains comprehension is proposed. The theory proposes that both processing and storage are mediated by activation and that the total amount of activation available in working memory varies among individuals. Individual differences in working memory capacity for language can account for qualitative and quantitative differences among college-age adults in several aspects of language comprehension. One aspect is syntactic modularity: The larger capacity of some individuals permits interaction among syntactic and pragmatic information, so that their syntactic processes are not informationally encapsulated. Another aspect is syntactic ambiguity: The larger capacity of some individuals permits them to maintain multiple interpretations. The theory is instantiated as a production system model in which the amount of activation available to the model affects how it adapts to the transient computational and storage demands that occur in comprehension.
