Phonological variation in spoken word recognition

描述(申请人提供)：这项研究的主要目的是了解语音变异是如何适应口语单词识别的。具体地说，我们考虑了音段变化的程度和听众接触到的不同类型的变化。我们考察了方言内变异、跨方言变异和跨语言变异，因为这些都是听者必须适应和适应的自然环境。参与者将被呈现具有多种自然发音的听觉刺激。将使用各种范式，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利用不同水平和过程的实验，并提供没有战略影响的趋同证据。总体而言，这项研究将加深我们对人类认知和语言处理工作方式的理解，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。

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.
