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）：本提案中描述的研究涉及在线阅读期间在线单词识别过程。在提案中，描述了许多研究，其中当受试者在句子上下文中读取了孤立的单词和单词，其中收集了眼动和电生理数据。该提案的目的是使用最具时间敏感的技术来检查阅读中语音表达的性质和时间。提出的实验检查了在分段和上段级别的语音表示，研究了元音，辅音和音节信息与单词识别有关的过程。这项研究对于理解一般的代表性过程，阅读开发，熟练阅读以及中央凹和parafoveal单词识别过程之间的关系应该很有用。
