DESCRIPTION (provided by applicant): Investigations of the formation, representation, and organization of concepts have been central to the field of cognitive psychology over the past several decades. One dominant theory of semantic memory (Allport, 1985) describes object concepts as distributed mental representations implemented in functionally and physically distinct attribute-domains that correspond to different sensory or motor domains of which they are also a part. In fact, according to Allport, these modules are the very same areas of the brain that are dedicated to processing sensorimotor information. One such attribute-domain that has been discussed extensively in the cognitive and cognitive neuroscience literatures is the domain of visual knowledge. This attribute-domain is the topic of investigation in the current proposal. Specifically, we aim (1) to characterize visual knowledge attribute-domains and, in particular, to examine subdivisions in conceptual representations about object appearance that parallel subdivisions in visual perception; (2) to explore variation in visual knowledge retrieval across different concepts and categories; (3) to investigate the link between visual knowledge and visual perception; and, (4) to relate individual differences in visual knowledge attribute-domains to variation in behavior and experience. The proposed experiments make use of a variety of methodologies, including behavioral experiments in normal subjects, congenitally blind adults, and brain-damaged patients, and neuroimaging experiments in both normal and congenitally blind subjects.

描述（由申请人提供）：过去几十年来，对概念的形成、表征和组织的研究一直是认知心理学领域的核心。语义记忆的一种主导理论（Allport，1985）将对象概念描述为在功能和物理上不同的属性域中实现的分布式心理表征，这些属性域对应于它们也是其中一部分的不同感觉或运动域。事实上，根据奥尔波特的说法，这些模块与大脑中专门处理感觉运动信息的区域完全相同。在认知和认知神经科学文献中广泛讨论的这样一个属性域是视觉知识领域。该属性域是当前提案中研究的主题。具体来说，我们的目标是（1）表征视觉知识属性域，特别是检查与视觉感知中的细分平行的物体外观概念表示中的细分； （2）探索不同概念和类别的视觉知识检索的变化； （3）研究视觉知识与视觉感知之间的联系； (4) 将视觉知识属性域中的个体差异与行为和经验的变化联系起来。拟议的实验利用了多种方法，包括在正常受试者、先天性失明成年人和脑损伤患者中进行的行为实验，以及在正常和先天性失明受试者中进行的神经影像学实验。
