Deficits in pragmatic language ability are common to a number of clinical populations, for example, right-hemisphere damage (RHD), Autism and traumatic brain injury (TBI). In these individuals the basic structural components of language may be intact, but the ability to use language to engage socially is impaired. Despite the nature of these difficulties being well documented, exactly what causes these difficulties is less clear. Furthermore, the current status of causal explanations for pragmatic difficulties across these populations is divergent and sometimes contradictory. This paper explores the empirical validity of three theories that attempt to explain pragmatic language impairment. It is recommended that a new, more convergent approach to investigating the causes of pragmatic language disability be adopted.
语用语言能力缺陷在许多临床群体中很常见，例如，右脑损伤（RHD）、自闭症和创伤性脑损伤（TBI）。在这些个体中，语言的基本结构成分可能完好无损，但使用语言进行社交互动的能力却受到损害。尽管这些困难的性质已有充分记录，但究竟是什么导致了这些困难却不太清楚。此外，目前针对这些群体语用困难的因果解释的现状存在分歧，有时甚至相互矛盾。本文探讨了三种试图解释语用语言障碍的理论的实证有效性。建议采用一种新的、更趋同的方法来研究语用语言障碍的成因。
