CORE--THEORETICAL ISSUES, CONSTRAINTS AND COMPUTATIONAL RESOURCES

该计划项目核心部分的目标是进一步 该项目理论框架的发展 通过探究BASIC来理解正常和无序的认知 理论问题，并培育融入理论 其他方面产生的制约因素和研究成果的框架 途径和方法。该项目的这一部分还将 证明了支持这四个部分项目的共享资源。二 我们最近的调查中出现了一些问题，作为主题 需要有重点的理论研究：(1) 在特定域中使用的表示，以及 塑造和激励他们的特征的约束。(2) 组织下列网络的性质和意义 从属于认知的各个方面，以及它们的原因 功能专门化。这些问题将通过以下方式解决 基于网络可能最优的思想的模拟模型 或者至少是约束集合的局部最优解。 探索这些限制如何影响处理和学习 将通过计算机建模研究来检查网络。

The aims of the core section of this program project are to further the development of the theoretical framework underlying the project for understanding normal and disordered cognition by exploring basic theoretical issues, and to foster the integration into the theoretical framework of constraints and research results arising from other approaches and methodologies. This part of the project will also proved shared resources that will support the four part projects. Two issues have emerged from our recent investigations as topics requiring focussed theoretical investigation: (1) The nature of the representations that are used in particular domains, and the constraints that shape and motivate their characteristics. (2) The nature and significance of the organization of the networks that subserve various aspects of cognition, and the reasons for their functional specialization. These issues will be addressed using simulation models based on the ideas that networks may be optimal or at least locally optimal solutions to an ensemble of constraints. Exploring how these constraints influence processing and learning in networks will be examined through computer modeling studies.
