Modeling Core

Modeling Core将为跨项目的所有计算建模提供一个中心资源。建模在这个研究项目中起着至关重要的作用，因为它将理论、行为和神经成像方法联系起来，以理解阅读和语言之间的关系。阅读的“三角模型”是这项事业的核心，因为它提供了一种机械的解释，说明拼写、音韵学和意义之间的映射是如何被学习和用来支持阅读的。在此框架下的先前工作已经提供了关于语音和语义处理如何促进读写结果的见解。这四个项目都将与三角模型接触，整合音系模型（项目二）和句子处理模型（项目四）的见解和新进展，将模型扩展到新语言（项目三），并研究各种语言能力中不同的构成缺陷模式如何对不同语言产生不同的影响（项目一）。这种综合的方法将为理论和实证工作开辟新的方向，并使阅读技能的发展和使用与言语和语言的一般理论取得进展。最后，与神经成像核心（Core B）的交互将产生解释和分析fMRI数据的新方法。这些模型的定位水平非常适合于此，因为它们为行为结果（如反应时间和准确性）以及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，这些项目和核心是统一阅读及其与语言关系的神经生物学和计算模型的核心

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
