This article concerns the relationship between social context, identity and intergroup relations. It reviews early formulations pertaining to contextual influences and proceeds to examine vitality theory, specifically, ethnolinguistic vitality (EV). The ensuing discussion considers objective aspects of EV such as the demographic representation of a group and delineates multiple influences modulating their impact on intergroup relations. Subjective formulations of EV focusing on how it is perceived are then examined in view of their interaction with intergroup issues such as ideologies, the formation of networks and language loss. While acknowledging the wide conceptual girth of EV, a central intergroup issue remains communication. Following through, issues pertaining to language acquisition are therefore scrutinized as they relate to EV, linguistic identification, and motivation. A parallel is drawn with Bourdeusian approaches, which orient the analysis toward the dynamics of power and investment. Specifically, attention is directed to ideological and identity processes underpinning the learner’s involvement in the learning task. The paper concludes with a discussion of the relevance of the concept of global English as well as the necessity for a framework of contextual factors reaching beyond intrapsychic constructs.

民族语言活力、身份和权力：对 SLA 的投资

本文关注社会背景、身份和群体间关系之间的关系。它回顾了与语境影响有关的早期表述，并继续研究活力理论，特别是民族语言活力 (EV)。随后的讨论考虑了 EV 的客观方面，例如一个群体的人口统计特征，并描述了调节它们对群体间关系的影响的多种影响。EV 的主观表述侧重于如何被感知，然后根据它们与群体间问题（如意识形态、网络的形成和语言损失）的相互作用进行检查。虽然承认电动汽车的概念范围很广，但一个核心的群体间问题仍然是沟通。因此，与语言习得有关的问题因与 EV 相关而受到仔细审查，语言识别和动机。与布尔德乌斯的方法相似，它将分析导向权力和投资的动态。具体而言，注意力集中在支撑学习者参与学习任务的意识形态和认同过程上。本文最后讨论了全球英语概念的相关性以及建立超越心理结构的语境因素框架的必要性。
