Stimulus variation and perceptual categorization

描述（由申请人提供）：本研究的主要目的是了解语音变化是如何适应口语单词识别的。具体地说，我们考虑了分段变化的程度和听众所暴露的不同类型的变化。我们考察了方言内的变化、跨方言的变化和跨语言的变化，因为这些都是听者必须适应和调整的自然环境。参与者将被呈现具有多种自然发音的听觉刺激。各种范式，包括语义启动，语音启动，音素识别和音素监测将被使用。这种多样性使我们能够设计利用不同层次和过程的实验，并提供不受战略影响的聚合证据。总的来说，这项研究将进一步加深我们对人类认知和语言处理如何工作的理解，使我们能够更好地模拟口语单词识别过程。从健康的角度来看，这很重要，因为理解和建模语言处理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.
