The proposed research will investigate the development of constructive spatial-cognition. Two studies are proposed. Study 1 will examine developmental changes in overt strategies for solving block design tasks using microgentic analysis. Videotapes of normally developing children between ages 4 years and 9 years will be coded for overall solution strategy, manipulation of individual cubes, and correctness of solutions. Data will be analyzed for developmental change as well as sequential course to correct solutions. In addition regression analyses will examine the relative contribution of perceptual characteristics of individuals designs and particular constructive behaviors necessary for correct solution. Findings from this study will provide important information on specific changes in constructive spatial-cognition which occur across development. Study 2 will examine these same issues for individuals who have a documented weakness in constructive spatial-cognition, particularly for block design tasks; adults with Williams syndrome. Results from Study 2 will be compared to findings from Study 1 to address issues of delay and deviance in spatial-cognition.

拟议的研究将调查建设性的发展 空间认知 提出了两项研究。 研究1将检查 解决组块设计任务的显性策略的发展变化 使用微观遗传分析。 正常发育儿童的录像带 4岁至9岁之间的儿童将被编码为整体解决方案 策略、单个立方体的操作以及解决方案的正确性。 将分析数据的发育变化以及序贯 正确的解决方案。 此外，回归分析将检查 个人知觉特征的相对贡献 设计和特定的建设性行为所必需的正确的 溶液 这项研究的结果将提供重要的信息， 具体的变化，在建设性的空间认知发生在 发展 第二项研究将对个人进行同样的研究 他们在建构性空间认知方面有缺陷 特别是对于积木设计任务;患有威廉姆斯综合征的成年人。 研究2的结果将与研究1的结果进行比较， 解决空间认知中的延迟和偏差问题。
