Object Concepts

项目摘要 对这个世界有所了解意味着什么？任何知识论的核心都是一种 概念，那些让我们能够对世界上的信息进行分类的精神表征。在这个项目中，我们 尝试通过研究概念的神经实例化来理解概念。这个项目的中心目标是 通过相似性的表征，提高我们对概念的神经表示的理解。这个 这项研究计划的更广泛的目标是开发一种理解神经表征的策略 所有类型的知识；但是，为了使这个问题更容易处理，我们将重点放在特定类型的 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 外表。具体地说，(1)我们的目标是通过刻画特征来描述对象概念的神经表征 神经调谐多维相似空间中的特征；(2)我们的目标是检查神经中的变异 跨概念、跨个体、跨注意状态的客体概念表征； 目的探讨睡眠依赖巩固过程在新客体概念习得中的作用 知识；(4)我们的目标是开发更多表征神经相似性的创新方法 一般说来。

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.
