NEUROPSYCHOLOGICAL MODEL OF DEVELOPMENTAL AGRAPHIA

研究计划的主要目标是继续这项计划 在前一次TIA中描述的。我们的计划是测试一条信息 发展性失写的加工模式，包括语言加工模式和语言加工模式 拼写和书写受损儿童的运动部件。这个 目前的建议与先前拨款的建议不同之处在于， 语言成分是从拼写的交互模型中衍生出来的 以及由Frith开发的阅读。具体的假设由以下两个方面生成 Frith和候选人与这些模型的关系，包括 关于音系学的有效和准确使用的预测 作为发展性阅读障碍的标志的能力及其崩溃 书写困难。另一个假设包括这样的预测，即 存在两种类型的发展性语言失写(语音或 发音困难和词汇障碍或发音障碍)，以及这些类型的书写困难 两者都将是由于音韵学方面的障碍。的总体目标是 电机部件将测试一个复杂的信息处理模型 手写，包括意念运动性失用症、运动编程和视觉 运动协调能力。 为了实现这些目标，研究项目将包括 正常儿童和发育迟缓儿童的测评 阅读困难和书写困难。他们将被给予一定的标准 神经心理测试和一系列特定的语言任务和 运动任务(许多是由应聘者设计的)来检查他们的语音 拼写和阅读能力，他们倾向于使非音素 并检查他们笔迹中马达故障的类型。 这些任务的设计、管理和解释将 在赞助商的监督下进行，并与 顾问。 分析将是两方面的。首先，将检验具体的假设 利用标准分析程序，最常见的是方差分析。 此外，在个案的基础上进行描述性分析，特别是 将进行笔迹障碍的检查 这些研究将使我们能够更好地理解发展 失写症。对这种常见疾病的更好的理解可能会导致 为患有该病的儿童开发更好的补救技术。在……里面 此外，提案的培训部分将提供 在研究发展性学习方面有进一步专业知识的候选人 残疾人士。

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.
