Effective pragmatic comprehension of language is critical for successful communication and interaction, but this ability is routinely impaired following Traumatic Brain Injury (TBI) (1,2). Individual studies have investigated the cognitive domains associated with impaired pragmatic comprehension, but there remains little understanding of the relative importance of these domains in contributing to pragmatic comprehension impairment following TBI. This paper presents a systematic meta-analytic review of the observed correlations between pragmatic comprehension and cognitive processes following TBI. Five meta-analyses were computed, which quantified the relationship between pragmatic comprehension and five key cognitive constructs (declarative memory; working memory; attention; executive functions; social cognition). Significant moderate-to-strong correlations were found between all cognitive measures and pragmatic comprehension, where declarative memory was the strongest correlate. Thus, our findings indicate that pragmatic comprehension in TBI is associated with an array of domain general cognitive processes, and as such deficits in these cognitive domains may underlie pragmatic comprehension difficulties following TBI. The clinical implications of these findings are discussed.
有效的语言语用理解能力对于成功的沟通与互动至关重要，但创伤性脑损伤（TBI）后这种能力常常受损（1,2）。个别研究已对与受损语用理解相关的认知领域进行了调查，但对于这些领域在导致TBI后语用理解受损方面的相对重要性仍知之甚少。本文对TBI后语用理解与认知过程之间观察到的相关性进行了系统的荟萃分析综述。进行了五项荟萃分析，量化了语用理解与五个关键认知结构（陈述性记忆；工作记忆；注意力；执行功能；社会认知）之间的关系。在所有认知测量与语用理解之间发现了显著的中度至强相关性，其中陈述性记忆是最强的相关因素。因此，我们的研究结果表明，TBI中的语用理解与一系列领域通用的认知过程相关，因此这些认知领域的缺陷可能是TBI后语用理解困难的基础。讨论了这些发现的临床意义。
