Whenever we use language to communicate, sounds, signs, and/or letters are combined into words that, in turn, form sentences, which together tell a story. Both language production and language comprehension rely on representations at different levels of granularity that need to be continuously and rapidly activated, selected, and combined. The representations themselves are specific to language, but many processes that regulate their use, such as inhibition of competitors or updating of working memory with new information, are so-called domain-general abilities that apply across different kinds of tasks. Here, we provide an overview of the behavioral and neurophysiological evidence in favor of domain-general abilities underpinning language skills and describe which particular aspects of production and comprehension draw upon such cognitive resources. We discuss how this line of research not only reveals important similarities between production and comprehension but also helps to establish links between language and other cognitive domains. Finally, we argue that studying how domain-general abilities are used in language will lead to important insights into the highly dynamic and efficient communication between brain networks that is necessary to successfully go from sounds to stories.
每当我们使用语言进行交流时,声音、符号和/或字母会组合成单词,这些单词又会构成句子,共同讲述一个故事。语言生成和语言理解都依赖于不同粒度水平的表征,这些表征需要持续且快速地被激活、选择和组合。这些表征本身是特定于语言的,但许多调节其使用的过程,比如抑制竞争项或用新信息更新工作记忆,都是所谓的通用能力,适用于不同类型的任务。在这里,我们概述了支持语言技能背后通用能力的行为和神经生理学证据,并描述了语言生成和理解的哪些特定方面利用了这些认知资源。我们讨论了这一系列研究如何不仅揭示了语言生成和理解之间的重要相似之处,还有助于建立语言与其他认知领域之间的联系。最后,我们认为研究通用能力在语言中的使用方式将有助于深入了解大脑网络之间高度动态且高效的交流,而这种交流对于成功地从声音过渡到故事是必不可少的。
