The proposed four-year research continues studies from the applicants' laboratory directed towards developing a model of the reading process to explain skilled reading, the acquisition of reading skill, and failure to read. The specific aims in the proposal concern the types of codes (visual, orthographic, phonological, morphemic, and semantic) used in reading with foveal and parafoveal vision. The methodology involves using eye movements in reading or reading-related tasks to study two general questions. The first question concerns how different codes are deployed in accessing the meaning of words. Three questions will be considered: 1) the way phonological information is extracted in the parafovea; 2) neighbor effects concern how word encoding is affected by the properties of closely related words; 3) morphemic coding will be studied with sound coding in other languages in which the relation between orthography and phonology is different from that in English. The second question concerns how attention is used during eye fixation, specifically, how covert modulation of incoming information occurs on a given eye movement fixation and how the eyes are driven to new locations during reading.

拟议的四年研究继续申请人的研究 实验室致力于开发阅读过程模型 解释熟练的阅读，阅读技能的获取以及未能 读。 提案中的具体目的涉及代码类型 （视觉，拼字，语音，形态学和语义） 带有凹和parafoveal的视觉阅读。 该方法涉及使用 阅读或与阅读相关的任务中的眼睛运动，以研究两个一般 问题。 第一个问题涉及如何部署不同的代码 在访问单词的含义时。 将考虑三个问题： 1）在Parafovea中提取语音信息的方式； 2） 邻居效应涉及单词编码如何受属性影响 密切相关的单词； 3）将使用声音研究形态学编码 用其他语言进行编码，其中拼字法与 语音学与英语不同。 第二个问题涉及 特别是在固定期间如何使用注意力，特别是如何秘密 传入信息的调节发生在给定的眼动固定 以及在阅读过程中如何将眼睛驱动到新位置。
