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从申请人的研究 一个实验室，旨在开发一个阅读过程的模型， 解释熟练的阅读，阅读技能的获得，和失败， read. 提案中的具体目标涉及守则的类型 （视觉的、拼写的、语音的、语素的和语义的）用于 用中央凹和旁凹视觉进行阅读。 该方法涉及使用 眼动在阅读或阅读相关的任务，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 来理解词语的含义 将审议三个问题： 1)语音信息的提取方式; 2） 相邻效应关注的是字编码如何受到这些属性的影响 3）语素编码将与语音一起研究 在其他语言中，正字法和 音系学与英语不同。 第二个问题涉及 注意力在眼睛注视过程中是如何被使用的，特别是， 输入信息的调制发生在给定的眼球运动注视上 以及在阅读期间眼睛如何被驱动到新的位置。
