Foveal and Parafoveal Codes in Reading

将进行一系列研究，以考察阅读中使用的代码的性质。这些研究 讨论正字法、语音、词汇和语义代码在中央凹和副中央凹中的使用情况 阅读中的视觉。在实验中，读者的眼球运动将被监测，并主要 技术包括根据读者眼睛的位置改变文本的显示方式。眼睛 将检查运动数据(注视时间、眼跳长度、注视概率和注视次数) 为了更准确地确定(1)如何使用不同的代码来获取固定单词的含义，(2) 如何在阅读过程中分配注意力，以及(3)各种代码(视觉、正字法、词汇、 语音和语义)用于跨注视整合信息。许多实验 与大学老年技术读者打交道，但我们也将在老年和初级阶段调查这些问题 读者，也包括中文读者。除了实证工作外，我们还将进一步发展E-Z 阅读器模型，以考虑更广泛的数据范围，并将其扩展到考虑眼球运动 初学者和老年读者以及中文读者的行为。实验与建模 工作应该使我们能够更好地理解熟练的阅读以及为什么有些人阅读不好。

A series of studies will be conducted to examine the nature of codes utilized in reading. The studies deal with how orthographic, phonological, lexical, and semantic codes are used in foveal and parafoveal vision during reading. In the experiments, readers' eye movements will be monitored and the primary technique involves making display changes in the text contingent upon the position of the readers' eyes. Eye movement data (fixation time, saccade length, fixation probability, and number of fixations) will be examined to determine more precisely (1) how different codes are used in accessing the meaning of fixated words, (2) how attention is deployed during reading, and (3) how the various codes (visual, orthographic, lexical, phonological, and semantic) are used in integrating information across fixations. Many of the experiments deal with college aged skilled readers, but we will also investigate these issues in elderly and beginning readers, as well as readers of Chinese. In addition to the empirical work, we will further develop the E-Z Reader model to account for a broader range of data, and also extend it to account for eye movement behavior in beginning and elderly readers, as well as Chinese readers. The experiments and the modeling work should make it possible to better understand skilled reading and why some people do not read well.
