DESCRIPTION (provided by applicant): Recent research has shown that naive listeners have significant success in identifying the regional dialect of unfamiliar talkers. This finding suggests that listeners encode detailed sociolinguistic information in memory and can draw on these representations to make explicit judgments about new talkers. The proposed project extends this line of research by exploring the interaction between this social-indexical variation and phonological processing. First, the role of linguistic experience in the activation and suppression of phonological dialect subsystems will be explored in a series of speech perception and production tasks. Second, the role of phonological similarity between two linguistic varieties in spoken language processing will be explored in the same series of perception and production tasks. Finally, an exemplar-based model of the representation of dialect variation will be developed to account for how linguistic information is perceived, encoded, and represented in long-term memory with respect to phonetic, phonological, and lexical categories.

描述（由申请人提供）：最近的研究表明，天真的听众在识别不熟悉的谈话者的地区方言方面取得了巨大的成功。这一发现表明，听众在记忆中编码了详细的社会语言信息，并可以利用这些表征对新谈话者做出明确的判断。拟议的项目通过探索这种社会索引变异与语音处理之间的相互作用来扩展这一研究方向。首先，将在一系列语音感知和生产任务中探讨语言经验在语音方言子系统激活和抑制中的作用。其次，将在同一系列的感知和生产任务中探讨两种语言变体之间的语音相似性在口语处理中的作用。最后，将开发一个基于范例的方言变异表示模型，以解释语言信息如何在语音、音系和词汇类别方面在长期记忆中被感知、编码和表示。
