在最初的测试（N = 36），作为全量表智商的函数，在WAIS-R的四个管理实践的差异效应进行了检查。12名受教育程度匹配的正常成年人分别代表三组：低平均（80-90），平均（95-105）和高平均（110-120）全量表智商。参与者每隔两周接受一次测试。重复测量方差分析表明，平均值和高平均值组在重新测试间隔内的增益大于低平均值组（p <0.002）。各组之间，第一次重测的增益大于第二次或第三次重测（p < .001）。量表×时间的交互作用表明，操作智商与言语智商的增长不成比例，特别是在第一次重测时（p < .001）。以前暴露于WAIS-R显着改变性能：传统的解释，预期增益和配置文件分析是无效的，在重新测试。
Differential effects of practice over four administrations of the WAIS-R were examined as a function of Full Scale IQ at initial testing (N = 36). Twelve education-matched normal adults represented each of three groups: Low-Average (80-90), Average (95-105), and High-Average(110-120)Full Scale IQ. Participants were tested at 2-week intervals. Repeated measures analysis of variance indicated that Average and High-Average groups made greater gains across retest intervals than did the Low-Average group (p < .002). Across groups, gains were greater at the first retest than at the second or third retest (p < .001). A Scale x Time interaction indicated disproportionate gain in Performance IQ versus Verbal IQ, particularly at the first retest (p < .001). Previous exposure to the WAIS-R dramatically alters performance: Traditional interpretations regarding expected gain and profile analysis are not valid at retest.
