项目摘要

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.

这项研究计划的主要目标是继续这项计划在以前的TIA中描述。计划是测试一个信息发展性失写症的加工模型，包括语言和拼写和书写受损的儿童的运动部件。的目前的建议与以前资助的建议不同，语言成分是从一个交互式的拼写模型中衍生出来的和阅读的能力。具体的假设是由以下两方面产生的： Frith和候选人与这些模型的关系，包括预测有关有效和准确地使用语音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（语音或发音困难和词汇困难），这些类型的书写困难都是由于语音学上的缺陷。2000年的总体目标是：运动组件将测试一个复杂的信息处理模型，手写，包括表意失用症，运动编程和视觉运动协调为了实现这些目标，研究项目将包括对正常儿童和发展障碍儿童的评价诵读困难和书写困难。他们会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，运动任务（许多由候选人设计），以检查他们的语音拼写和阅读能力，他们的倾向，使非语音错误，并检查其笔迹中的电机故障类型。这些任务的设计、管理和解释将在申办者的监督下并与顾问。分析将是双重的。首先，将检验具体假设利用标准分析程序，最常见的是方差分析。此外，在个案基础上进行描述性分析，特别是将进行书写障碍检查这些研究将使我们更好地了解发展失写症对这种常见疾病的进一步了解可能会导致发展更好的补救技术，为儿童与它。此外，建议的培训部分将提供在研究发展性学习方面有进一步专业知识的候选人残疾。
