Project Summary What does it mean to know something about the world? Central to any theory of knowledge is a theory of concepts, those mental representations that allow us to categorize information in the world. In this project, we attempt to understand concepts by studying their neural instantiation. The central aim of this project is to advance our understanding of the neural representation of concepts via a characterization of similarity. The broader goal of this research program is to develop a strategy for understanding the neural representation of all types of knowledge; however, to make this problem more tractable, we are focusing on a specific type of concept - concrete objects - and on a particular type of knowledge about those concepts - their visual appearance. Specifically, (1) We aim to describe the neural representation of object concepts by characterizing neural tuning to features in a multidimensional similarity space; (2) We aim to examine variation in the neural representations of object concepts, across concepts, across individuals, and across attentional states; (3) We aim to explore to role of sleep-dependent consolidation processes in the acquisition of new object concept knowledge; (4) We aim to develop innovative methods for the characterization of neural similarity more generally.

项目摘要 了解世界意味着什么？任何知识理论的中心是一种理论 概念，那些使我们能够对世界上信息进行分类的心理表征。在这个项目中，我们 试图通过研究其神经实例化来理解概念。该项目的核心目的是 通过表征相似性的特征来促进我们对概念神经表示的理解。这 该研究计划的更广泛的目标是制定一项策略，以了解 所有类型的知识；但是，为了使这个问题更容易解决，我们专注于特定类型的 概念 - 具体对象 - 以及关于这些概念的特定类型的知识 - 它们的视觉 外貌。具体而言，（1）我们旨在通过表征来描述对象概念的神经表示 在多维相似性空间中的神经调整到特征； （2）我们旨在检查神经的变化 对象概念，跨概念，跨个体以及跨注意状态的表示； （3）我们 旨在探索依赖睡眠的合并过程在获取新对象概念中的作用 知识; （4）我们旨在开发创新的方法来表征神经相似性 一般来说。
