This paper investigates the learning of indexical features by English-speaking adults using a novel experimental paradigm. Participants learn an allomorphy pattern cued by a given social context. The social contexts are represented by conversation partners who differ by age, ethnicity and/or gender and are positioned in various ways. The results show that, after training, participants are able to learn that different types of conversation partners prefer different types of allomorphs, but that learning and generalisation hinges on the social relevance of the cue represented by the conversation partner.

并非所有索引线索都是平等的：对人工语言中索引意义维度的不同敏感性

本文使用一种新的实验范式研究了说英语的成年人对索引特征的学习。参与者学习由给定的社会环境提示的同种异形模式。社交环境由年龄、种族和/或性别不同并以各种方式定位的对话伙伴表示。结果表明，经过培训，参与者能够了解到不同类型的对话伙伴更喜欢不同类型的同种异形体，但学习和概括取决于对话伙伴所代表的线索的社会相关性。
