The present study investigated WAIS indices of scatter in a sample of 83 mentally retarded adults (FIQ, means = 58). Overall subtest scatter was significantly correlated with VIQ, PIQ and FIQ. There was no significant relationship between the discrepancy score (absolute value of the difference between VIQ and PIQ), and VIQ, PIQ and FIQ. The scatter and discrepancy score means were surprisingly large. Analysis of VIQ and PIQ configuration revealed that VIQ greater than PIQ, and PIQ greater than VIQ occurred with nearly equal frequency.
本研究调查了83名智力迟钝成年人样本（智商均值 = 58）的韦氏成人智力量表（WAIS）离散指数。总体分测验离散度与言语智商（VIQ）、操作智商（PIQ）和总智商（FIQ）显著相关。言语智商与操作智商差异分数（VIQ与PIQ差值的绝对值）与VIQ、PIQ和FIQ之间无显著关系。离散度和差异分数均值出奇地大。对VIQ和PIQ配置的分析表明，VIQ大于PIQ和PIQ大于VIQ的出现频率几乎相等。
