中心背景下的空间发展研究 一直局限于空间分析处理的子集， 人口群体。 在中心的这一阶段，我们将扩大我们的研究， 空间处理，系统地检查之间的关系 不同层次的空间处理。 空间认知表现 任务可能需要不同级别的空间处理。 所以我们 需要定义和研究空间过程，从最基本的 注意力机制的复杂规划方面，并比较 这些水平的缺陷和正常处理的概况 处理. 局灶性病变人群将用作以下的基础： 产生关于可能的关联的具体假设， 分离的空间处理，因为它们与病变， 特定的大脑区域。 局灶性病变人群构成核心 在中心内的人口，因为他们是我们有谁组 对神经功能缺损的最佳描述，以及我们 可以对性能配置文件做出最强的预测， 空间处理领域。 它提供了一种定义空间 进程可以分开。 在这个意义上，局灶性病变人群 提供了一个正常发展的窗口。 如果减值情况反映 在空间分析系统的正常点的分裂，然后根据我们的 调查结果，应该有可能设计研究， 正常发育的儿童的轮廓是为了呼应儿童的轮廓， 早期损伤。 局灶性病变人群的研究提供了 有机会创建验证性测试周期，这有助于 定义正常处理的性质，并指定模式 的损害。 所有这些工作都可以推广到人口的研究 病变不太明显 空间处理的四个子域将 将通过与Eric的新合作启动 加州大学圣地亚哥分校的库尔切斯 Courchesne博士在国际上享有盛誉， 对正常和受损人群的注意力研究。 他提出 一系列的研究集中在注意力的基本机制上。 这些 研究对于我们理解其他空间环境中的性能非常重要。 域. 我们对空间认知的研究将包括 我们在空间分析方面的工作以及对心理旋转的新研究。 空间记忆的任务将包括一个新的位置记忆任务和 使用Rey Osterreith Complex Figure的记忆任务。 最后，将开始 来检查执行功能的发展。

Previous studies of spatial development within the context of the Center have been limited and focused on spatial analytic processing in a subset of population groups. In this phase of the Center we will expand our study of spatial processing to systematically examine the relations between the various levels of spatial processing. Performance on spatial cognitive tasks may require different levels of spatial processing. Therefore, we need to define and study spatial processes ranging from the most basic attentional mechanisms to aspects of complex planning, and to compare profiles of deficit and normal processing across these levels of processing. The focal lesion populations will be used as the basis for generating specific hypotheses about possible associations and dissociations in spatial processing as they are related to lesions in particular brain regions. The focal lesion population constitutes a core population within the Center in that they are the group for whom we have the best descriptions of neurological deficit, and the group for whom we can make the strongest predictions about performance profiles within the area of spatial processing. The provide a means of defining how spatial processes can come apart. In this sense, the focal lesion population provides a window on normal development. If profiles of impairment reflect normal points of cleavage in the spatial analytic system, then based on our findings,, it should be possible to design studies which in the performance of normally developing children is made to echo the profiles of children with early injury. The study of the focal lesion population provides the opportunity to create cycles of confirmatory testing which can help to define the nature or normal processing and as well as to specify patterns of impairment. All of this work can be extended to the study of population with less well defined lesions. Four subdomains of spatial processing will be examined: will be initiated through a new collaboration with Eric Courchesne at UCSD. Dr Courchesne has an international reputation for studies of attention in normal and impaired populations. He has proposed a series of studies focused on basic mechanisms of attention. These studies are important to our understanding of performance in other spatial domains. Our studies of spatial cognition will include both an extension of our work in spatial analysis as well as a new study of mental rotation. Tasks of spatial memory will include a new memory for location task and the memory task using the Rey Osterreith Complex Figure. Finally, will begin to examine the development of executive functioning.
