The principal objective of this project is the continuation of our research on the neural basis of face processing. We plan to explore further the ability of patients with defective recognition of face identity to recognize facial expressions. we aim at uncovering the factors that account for this, and which, in turn, might shed light on the normal mechanisms for the recognition of faces. We will also investigate whether face agnostics can generate facial expressions normally. In a second line of studies, we attempt to validate the idea that the unusually high degree of visual "ambiguity" in faces (as defined by similarities in local and global shapes and overall configuration) largely explains the "special" status of faces as a class of stimuli. Another set of studies will explore the ability of face agnostics to recognize entities other than faces that also require identification at a unique level, e.g., unique landscapes and buildings. We will continue to explore the phenomenon of nonconscious face recognition in face agnostic patients. The significance of the studies outlined under this project ties directly into the objectives specified for Memory and Language. In particular, the studies will contribute to our understanding of the neural mechanisms that subserve learning and recognition in humans, at systems level. In this project, the emphasis will be on learning and recognition processes that are responsible for disambiguating entities at the most subordinate level of taxonomy, i.e., the individual exemplar level. Faces are the quintessential instance of such stimuli and as such they warrant special investigation. These studies are also important in the potential consolidation and expansion of knowledge regarding the ability of the brain to learn and to recognize at a nonconscious, covert level. In addition to the value of such knowledge to further understanding of the neural underpinnings of learning and memory, such information will provide a basis for developing behavioral management programs tailored to the needs of patients with visual recognition disorders.

这个项目的主要目的是继续我们的研究 面部处理的神经基础。 我们计划进一步探讨 具有面部身份识别缺陷的患者 识别面部表情 我们的目标是揭示 解释了这一点，这反过来可能会揭示正常的 面部识别的机制。 我们还将调查 面部不可知论者可以正常地生成面部表情。 在第二行 研究，我们试图验证的想法，异常高的程度， 面部的视觉“模糊性”（由局部和局部的相似性定义） 全球形状和整体配置）在很大程度上解释了“特殊” 作为一类刺激的面孔的状态。 另一组研究将探讨 面部不可知论者识别除面部以外的实体的能力， 还需要在唯一级别上进行标识，例如，独特的景观和 建筑 我们将继续探讨无意识面孔现象 面部不可知患者的识别。 研究的意义 本项目所概述的内容直接与 记忆与语言 这些研究将有助于我们 了解有助于学习的神经机制， 在系统层面上的人类认知。 在这个项目中，重点 将是学习和认可的过程， 在分类法的最下级级别消除实体的歧义，即， 个人示范水平。 面孔是一种典型的 这种刺激，因此，他们值得特别调查。 这些研究 在潜在的巩固和扩展方面也很重要， 关于大脑学习和识别能力的知识， 一种无意识的隐蔽状态 除了这些知识的价值之外 进一步了解学习的神经基础， 记忆，这些信息将为发展行为提供基础。 管理方案，为患者的视觉需求量身定制 认知障碍
