DESCRIPTION (provided by applicant): The research described in this proposal is concerned with on-line word recognition processes during silent reading. In the proposal, a number of studies are described in which eye movement and electrophysiological data are collected as subjects read isolated words and words in sentence contexts. The goal of the proposal is to use the most temporally sensitive technologies available to examine the nature and timecourse of phonological representations in reading. The proposed experiments examine phonological representation at the segmental and supra-segmental levels, investigating the processes by which vowel, consonant, and syllable information is involved in word recognition. This research should be useful in understanding representational processes in general, reading development, skilled reading, and the relationship between foveal and parafoveal word recognition processes.

描述（由申请人提供）：本提案所描述的研究是关于默读时的在线单词识别过程。在该提案中，描述了许多研究，这些研究在受试者阅读孤立单词和句子上下文中的单词时收集眼球运动和电生理数据。该提案的目标是使用最具时间敏感性的技术来检查阅读中语音表征的性质和时间进程。提出的实验在分音和超分音水平上检查语音表征，研究元音、辅音和音节信息参与单词识别的过程。本研究将有助于理解表征过程、阅读发展、熟练阅读以及中央凹和副中央凹文字识别过程之间的关系。
