The Florida Learning Disabilities Research Center

描述（由申请人提供）：该中心的主要目标是通过多学科和综合性的努力，促进我们对学习障碍的理解。该研究计划的中心主题是在上下文中解决学习障碍的复杂性。 我们通过应用最先进的方法，使学习障碍的现实模型易于处理。我们的方法是多学科的，从分子遗传学，行为遗传学，教师教育，教育心理学，发展心理学，认知心理学和认知科学领域的代表。该中心包括六个项目和四个核心。项目I，定义，分类和子类型开发和测试一个新的学习障碍的多变量模型。项目二，学习障碍，阅读理解，和课堂环境，检查有阅读障碍的学生的学习环境。项目三，书面表达的纵向和实验性调查，研究写作的发展和残疾的书面表达的背景。项目IV，佛罗里达双胞胎项目的阅读，行为和环境，分析了基因和环境的相互作用，在一个大规模的双胞胎研究。项目五，幼儿执行功能，注意力和阅读技能/残疾的发展，检查执行功能的发展，从学龄前开始。项目六，严重SRD的非裔美国人家庭的基因组序列模式分析，分析阅读残疾的基因组基础。中心的工作由四个核心支持：行政核心、服务核心、数据核心和PMRN核心。 公共卫生相关性：学习障碍是一种高发生率的残疾，对上学和以后的工作成功都有深远的影响。拟议的工作有可能提高我们对学习障碍的理解，并改善诊断和治疗。

DESCRIPTION (provided by applicant): The major objectives of the Center are to advance our understanding of learning disabilities through a multidisciplinary and integrative effort. The central theme of the research program is tackling complexities of learning disabilities in context. We do so by applying state-of-the-art methods that make realistic models of learning disabilities tractable. Our approach is multi-disciplinary, with representation from fields of molecular genetics, behavior genetics, teacher education, educational psychology, developmental psychology, cognitive psychology, and cognitive science. The Center comprises six projects and four cores. Project I, Definition, Classification, and Subtyping develops and tests a new multivariate model of learning disabilities. Project II, Learning Disabilities, Reading Comprehension, and the Classroom Environment, examines the learning context of students with reading disabilities. Project III, A Longitudinal and Experimental Investigation of Written Expression, examines the development of writing and disabilities in written expression in context. Project IV, the Florida Twin Project on Reading, Behavior, and Environment, analyzes the interplay of genes and environments in a large-scale twin study. Project V, Development of Executive Functioning, Attention, and Reading Skills/Disability In Young Children, examines the development of executive functioning from preschool on. Project VI, Genomic Sequence Pattern Analyses in African-American Families with Severe SRD, analyzes genomic bases of reading disability. The work of the Centers is supported by four cores: an Administrative Core, a Service Core, a Data Core, and a PMRN Core. PUBLIC HEALTH RELEVANCE: Learning disabilities represent a high-incidence disability with profound consequences for both schooling and later job success. The proposed work has the potential to improve our understanding of learning disabilities and to improve diagnosis and treatment.
