项目摘要

The Modeling Core will provide a central resource for all computational modeling across projects. Modeling plays a critical role in this program of research because it links theoretical, behavioral and neuroimaging approaches to understanding the relationship between reading and speech. The "triangle model" of reading is central to this enterprise because it provides a mechanistic explanation of how mappings among spelling, phonology and meaning are learned and used to support reading. Prior work in this framework has provided insights into how phonological and semantic processing contribute to literacy outcomes. All four projects will make contact with the triangle model, integrating insights and new advances from models of phonology (Project II) and sentence processing (Project IV), extending the model to new languages (Project III) and examining how different patterns of constitutive deficits in a variety of language abilities can have different impacts across languages (Project I). This integrative approach will open up new directions in the theoretical and empirical work, and make progress toward a general theory relating the development and use of reading skill to speech and language. Finally, interaction with the Neuroimaging Core (Core B) will produce new ways of interpreting and analyzing fMRI data. The models are pitched at a level that is well-suited to this, because they provide proxies for both behavioral outcomes such as response time and accuracy, as well as internal states that can be directly related to brain activity. Thus, the Modeling Core will coordinate activities across projects and cores that are central to unifying the neurobiological and computational models of reading and its relation to speech

建模核心将为各个项目的所有计算建模提供中心资源。建模在该研究计划中起着关键作用，因为它将理论，行为和神经影像学方法联系起来，以了解阅读与语音之间的关系。阅读的“三角模型”是该企业的核心，因为它提供了一种机械性解释，该解释是如何学习和用于支持阅读的拼写，语音学和含义之间的映射。此框架的先前工作为语音和语义处理如何促进识字结果提供了见解。所有四个项目都将与三角模型接触，从而整合了语音学模型（项目II）和句子处理（项目IV），将模型扩展到新语言（Project III）并检查各种语言能力中不同语言缺陷的不同模式如何在语言上产生不同的影响（项目I），将模型扩展到新语言（项目III）。这种综合方法将在理论和经验工作中打开新的方向，并向一般理论迈进，将阅读技能与语音和语言联系起来。最后，与神经成像核心（核心B）的相互作用将产生解释和分析fMRI数据的新方法。这些模型以非常适合这一点的水平倾斜，因为它们为诸如响应时间和准确性等行为结果以及可以与大脑活动直接相关的内部状态提供了代理。因此，建模核心将协调跨项目和核心的活动，这些活动是统一阅读的神经生物学和计算模型及其与语音的关系
