This article provides a critical review of the theoretical underpinnings of two core concepts in language socialization research: input and communicative competence. We organize our discussion along two major lines of inquiry: ( a) the historical-local and ( b) the language contact–globalization bodies of work. The first part of the article contests the persistent view that input reduces to vocabulary and grammatical structures. To this end, it provides evidence for a more multifaceted approach to input that involves multiparty participant frameworks and multimodality in culturally diverse language socialization ecologies. In this vein, it problematizes language gap studies that are based on middle-class language acquisition models of mother–child dyadic verbal input. The second part of the article challenges monolingual, developmental, and speaker-based models of communicative competence that assume a linear evolution from lesser to greater communicative competence and from more peripheral to more central community membership. It also offers evidence for how communicative competence is socioculturally constructed and, sometimes, interactionally distributed. Expected final online publication date for the Annual Review of Linguistics, Volume 7 is January 14, 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

本地与全球交汇处的语言社会化：输入与交际能力的竞争轨迹

本文对语言社会化研究中两个核心概念的理论基础进行了批判性回顾：输入和交际能力。我们沿着两条主要的探究路线组织我们的讨论：(a) 历史-地方性和 (b) 语言接触-全球化的工作主体。文章的第一部分对输入简化为词汇和语法结构的持久观点提出了质疑。为此，它为一种更加多方面的输入方法提供了证据，该方法涉及多方参与者框架和多元文化语言社会化生态系统中的多模态。在这方面，它对基于母子二元语言输入的中产阶级语言习得模型的语言差距研究提出了问题。文章的第二部分挑战单语、发展、以及基于说话者的交际能力模型，假设从较低的交际能力到较高的交际能力以及从更边缘到更中心的社区成员的线性演变。它还提供了交际能力是如何在社会文化上构建的，有时是交互分布的证据。《语言学年度评论》第 7 卷的预计最终在线出版日期为 2021 年 1 月 14 日。有关修订后的估计，请参阅 http://www.annualreviews.org/page/journal/pubdates。
