It is well established that Canadians produce higher raw scores than their U.S. counterparts on intellectual assessments. As a result of these differences in ability along with smaller variability in the population's intellectual performance, Canadian normative data will yield lower standard scores for most raw score points compared to U.S. norms.…

For this study, European WAIS III performance subtest norms were compared to the original US norms. When European WAIS III raw scores were scored using US norms, the resulting perceptual organization index (POI) means were significantly higher than the processing speed index (PSI) means. The POI/PSI difference is roughly 5-10 points for the German…

It was predicted that there would be variable IQ discrepancies at different ages because of differential age adjustments on the norms of the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised (WAIS-R). The use of equivalent WAIS and WAIS-R sums of scaled scores demonstrated the predicted variable discrepancies. (Author/BW)
