经常观察到患者违反WAIS-R区组设计子测试的总体配置。这些几何误差的意义进行了研究与分层模式组成的大的“全球”的形状从较小的“本地”的形状。受试者进行了两个相似性判断任务，他们被要求决定两个层次结构的比较数字最像一个标准的数字。结果表明，在区组设计中出现配置错误的受试者比没有出现配置错误的匹配样本更不可能选择与全球水平的标准数字相似的比较数字。此外，目前的研究结果是从没有已知的右半球病变的受试者中获得的，这表明区组设计错误和整体/局部性能之间的相关性适用于广泛的患者和非患者人群。这些数据与以下观点一致，即块设计上的错误可能反映了全局/局部特征的感知编码的差异。
Patients have been frequently observed to violate the overall configuration on the WAIS-R Block Design subtest. The significance of these configural errors was investigated with hierarchical patterns consisting of large "global" shapes made from smaller "local" shapes. Subjects were administered two similarity judgment tasks in which they were asked to decide which of two hierarchically structured comparison figures most resembled a standard figure. Results indicated that subjects who made configural errors on Block Design were less likely than a matched sample who did not make configural errors to select the comparison figure that resembled the standard figure at the global level. Furthermore, the present findings were obtained from subjects without known right-hemisphere lesions, suggesting that the correlation between Block Design errors and global/local performance is applicable to a broad range of patient and non-patient populations. The data are consistent with the view that errors on Block Design may reflect differences in the perceptual encoding of global/local features.
