The Nature of Phonological Representation in Reading

描述（由申请人提供）：拟议的研究考察了熟练阅读利用口语处理机制的程度和目的。它研究了阅读中使用的语音表征的性质，以及这些表征如何与用于处理口语的多层语音结构进行比较。四个实验将通过监测大学生读者在默读以理解句子时的眼球运动来收集行为数据。事件相关电位（ERP）实验将测量默读多音节单词时的诱发电位。这些实验将有助于阐明语音在熟练阅读中的作用，特别是在以下方面：(a)表明词汇前语音表征完全指定的程度；(b)区分词汇前和词汇后出现的音位要素；(c)确定语音表征对阅读过程的整体程度；(d)确定如何使用语音表征来支持熟练阅读。研究结果将支持连贯的阅读语音表征理论的发展，这将为未来的口语和书面语加工研究奠定基础。更好地理解语音在阅读中的作用将有助于提高阅读教学的有效性，并有助于理解语言障碍与阅读能力中断之间的关系。

DESCRIPTION (provided by applicant): The proposed research examines the extent to which proficient reading utilizes mechanisms of spoken language processing and for what purposes. It investigates the nature of phonological representations used in reading and how these representations compare to the multi-layered phonological structures used to process spoken language. Four experiments will gather behavioral data by monitoring the eye movements of college readers while they silently read sentences for comprehension. A fifth event-related potential (ERP) experiment will measure evoked potentials during the silent reading of multi-syllable words. These experiments will help clarify the role of phonology in proficient reading, particularly in terms of: (a) indicating the degree to which pre-lexical phonological representations are fully specified; (b) distinguishing pre-lexical phonological elements from those that arise post-lexically; (c) determining how integral the phonological representation is to the reading process; and (d) identifying how the phonological representation is used to support proficient reading. Findings will support the development of a coherent theory of phonological representation in reading that will provide a foundation for future research in the processing of spoken language and written text, A better understanding of just how phonology is involved in reading would be useful in improving the effectiveness of reading instruction and in understanding the relation between language disorders and disruptions of reading proficiency.
