Abstract For a long time, linguists more or less denied the existence of individual differences in grammatical knowledge. While recent years have seen an explosion of research on individual differences, most usage-based research has failed to address this issue and has remained reluctant to study the synergy between individual and community grammars. This paper focuses on individual differences in linguistic knowledge and processing, and examines how these differences can be integrated into a more comprehensive constructionist theory of grammar. The examination is guided by the various challenges and opportunities that may be extracted from scattered research that exists across disciplines touching on these matters, while also presenting some new data that illustrate how differentiation between individuals can improve models of long-term language change. The paper also serves as the introduction to this special issue of Cognitive Linguistics, which collects seven contributions from various linguistic disciplines focusing on key aspects of individuals’ grammars.

复杂系统中的个性：建构主义方法

摘要长期以来，语言学家或多或少地否认语法知识存在个体差异。近年来，关于个体差异的研究激增，但大多数基于使用情况的研究未能解决这一问题，并且仍然不愿研究个体语法与社区语法之间的协同作用。本文着重于语言知识和处理上的个体差异，并研究如何将这些差异整合到更全面的建构主义语法理论中。该考试以各种挑战和机遇为指导，这些挑战和机遇可以从涉及这些问题的跨学科的分散研究中获得，同时还提供了一些新数据，这些数据说明了个体之间的差异如何改善长期语言变化的模型。本文还作为本期《认知语言学》的导论，该书收集了来自各个语言学科的七篇有关个人语法关键方面的文章。
