DESCRIPTION (provided by applicant): The main goal of this study is to understand how phonological variation is accommodated in spoken word recognition. Specifically, we consider the degree of segmental variation and the different types of variation to which listeners are exposed. We examine within-dialect variation, cross-dialect variation, and cross-language variation, as these are all natural environments to which listeners must adapt and adjust. Participants will be presented with auditory stimuli that have multiple, naturally occurring pronunciations. A variety of paradigms, including semantic priming, phonological priming, phoneme identification, and phoneme monitoring will be used. This variety allows us to design experiments that tap different levels and processes, and provide converging evidence free of strategic effects. Overall, this research will further our understanding of how human cognition and language processing work, enabling us to better model the spoken word recognition process. This is important from a health perspective, as an understanding and modeling of language processing is beneficial in helping people with language and other cognitive deficits.

描述（由申请人提供）：这项研究的主要目标是了解语音变化是如何适应口语单词识别。具体来说，我们考虑的程度分段的变化和不同类型的变化，听众所暴露的。我们研究方言内的变化，跨方言的变化，跨语言的变化，因为这些都是自然环境，听众必须适应和调整。将向参与者呈现具有多种自然发音的听觉刺激。本研究将采用多种范式，包括语义启动、语音启动、音素识别和音素监控。这种多样性使我们能够设计出利用不同层次和过程的实验，并提供不受战略影响的趋同证据。总的来说，这项研究将进一步了解人类认知和语言处理是如何工作的，使我们能够更好地模拟口语识别过程。从健康的角度来看，这一点很重要，因为对语言处理的理解和建模有助于帮助有语言和其他认知缺陷的人。
