The primary goal of the research program are to continue the plan described in the previous TIA. The plan is to test an information processing model of developmental agraphia, including both linguistic and motor components in children who have impaired spelling and writing. The present proposal differs from the previously funded proposal in that the linguistic components are derived from an interactive model of spelling and reading developed by Frith. Specific hypotheses are generated both by Frith and by the candidate in relationship to these models including predictions regarding the efficient and accurate use of phonologic ability and its breakdown as the hallmark of developmental dyslexia and dysgraphia. An additional hypotheses includes the prediction that there exist two types of developmental linguistic agraphia (phonological or dysphonetic and lexical or dyseidetic) and that these types of dysgraphia will both be due to impairments in phonology. The broad objective for the motor component will be to test a complex information processing model of handwriting that includes ideomotor apraxia, motor programming and visual motor coordination. In order to accomplish these objects, the research project will include the assessment of normal children and children with developmental dyslexia and dysgraphia. They will be given certain standard neuropsychological tests and a series of specific linguistic tasks and motor tasks (many designed by the candidate) to examine their phonologic spelling and reading ability, their tendency to make non-phonological errors and to examine the types of motor breakdown in their handwriting. The design, the administration and the interpretation of these tasks will be done under the supervision of the sponsor and in consultation with the consultant. The analysis will be two-fold. First, specific hypotheses will be tested utilizing standard analytic procedures, most often analysis of variance. In addition, descriptive analysis on a case by case basis, especially for disorders of handwriting will be performed These studies will allow a better understanding of developmental agraphia. Improved understanding of this common disorder may lead to the development of better remediation techniques for children with it. In addition, the training component of the proposal will provide the candidate with further expertise in studying developmental learning disabilities.

研究计划的主要目标是继续该计划 之前的 TIA 中已经描述过。该计划是测试一个信息 发展性失写症的处理模型，包括语言和 拼写和书写障碍儿童的运动部件。这 本提案与之前资助的提案的不同之处在于 语言成分源自拼写的交互式模型 和弗里斯开发的阅读。具体的假设是由 弗里斯和候选人与这些模型的关系包括 关于语音的有效和准确使用的预测 能力及其崩溃作为发展性阅读障碍的标志 书写困难。 另一个假设包括预测 存在两种类型的发展性语言失写症（语音或 发音障碍和词汇障碍）以及这些类型的书写障碍 两者都是由于音韵学的缺陷造成的。的总体目标是 电机组件将测试复杂的信息处理模型 手写，包括意念运动失用症、运动编程和视觉 motor coordination. 为了实现这些目标，该研究项目将包括 正常儿童和发育障碍儿童的评估 阅读障碍和书写困难。他们将被给予一定的标准 神经心理学测试和一系列特定的语言任务和 运动任务（许多由考生设计）来检查他们的语音 拼写和阅读能力，他们的非语音倾向 错误并检查他们笔迹中运动故障的类型。 这些任务的设计、管理和解释将 在申办者的监督下并与主办方协商后进行 顾问。 分析将分为两部分。首先，将测试具体假设 利用标准分析程序，最常见的是方差分析。 此外，还要根据具体情况进行描述性分析，特别是对于 将进行笔迹障碍 这些研究将有助于更好地了解发育 失写症。加深对这种常见疾病的了解可能会导致 为患有该病的儿童开发更好的治疗技术。在 此外，该提案的培训部分将提供 在研究发展学习方面具有进一步专业知识的候选人 残疾。
