The broad, long-term objectives of the present research proposal are to electrophysiologically and behaviorally investigate the development of the neurocognitive language-processing system in normal and language- impaired (LI) children so as to establish the identity and timecourse of development of reading-related skills in 5- to 8-year-old beginning readers. Once established, this sort of knowledge can be applied to methods for teaching reading and to design of interventions for reading- disabled children. Electrophsiologically, event-related potentials (ERPs) will be recorded over multiple brain regions as normal and LI children process stimuli designed to activate specific aspects of sensory and language functions; behaviorally, scores on standardized reading tests will measure reading fluency. Three ERP experiments are proposed to investigate (1) the development of auditory and visual, semantic and syntactic sentence-processing in the same normal children and the relationship between ERP measures of these sorts of processes and behavioral reading fluency; (2) the development of basic visual, auditory, and phonological processes in normal children as measured by ERPs, and their relationship to behavioral reading fluency; and (3) the development of basic visual, auditory, and phonological processes in LI children as measured by ERPs, and their relationship to reading fluency and possible deviance from the course of normal development.

本研究建议的广泛，长期的目标是在正常和语言受损（LI）儿童中在电生理和行为上调查神经认知语言处理系统的发展，以确立5至8岁年龄在5岁的开始阅读器中阅读相关技能发展的身份和时间。建立后，这种知识可以应用于教学阅读和设计障碍儿童干预措施的方法。在电学上，与事件相关的电位（ERP）将在正常的多个大脑区域记录，而Li儿童则旨在激活感官和语言功能的特定方面的刺激；从行为上讲，标准化阅读测试的分数将测量阅读流利度。提出了三个ERP实验，以研究（1）在同一正常儿童中的听觉，视觉，语义和句法句子处理的发展以及这些过程的ERP测量与行为阅读流利的关系； （2）通过ERP衡量的正常儿童的基本视觉，听觉和语音过程的发展，以及它们与行为阅读流利的关系； （3）通过ERP衡量的LI儿童中基本的视觉，听觉和语音过程的发展，以及它们与正常发展过程中的阅读流利性以及可能的偏差。
