ABSTRACT Background: Aphasia research has been informed by linguistic theory to a great extent. Conversely, linguistic theory has also been informed by data from people with aphasia, albeit to a lesser extent. Aims: This overview to the Special Issue of Aphasiology entitled “Aphasia and linguistic theory: What we have captured so far” presents a narrative review that aims to illustrate the contribution of linguistic theory to aphasia research, and also includes a section that presents the articles making up the special issue. The narrative review, which is not exhaustive, highlights influential theoretical frameworks and linguistic constructs that have been central to accounts of language impairment in aphasia. Main Contribution: The overview illustrates the contribution of linguistic theory to aphasiology and paves the way for the development of a unified approach to aphasia, which will incorporate insights not only from theoretical linguistics, but also from other complementary fields, such as psycholinguistics, cognitive (neuro)psychology, and neuroscience of language.

语言理论和失语症：概述

摘要背景：失语症研究在很大程度上受到语言学理论的影响。相反，语言理论也受到失语症患者的数据的启发，尽管程度较小。目标：这篇题为“失语症和语言学理论：迄今为止我们所捕捉到的内容”的失语症特刊的概述提供了一个叙述性评论，旨在说明语言学理论对失语症研究的贡献，还包括一个介绍文章的部分弥补特刊。叙述性评论并非详尽无遗，重点介绍了有影响力的理论框架和语言结构，这些理论框架和语言结构对于失语症语言障碍的解释至关重要。主要贡献：
