The Wechsler Adult Intelligence Scale-Revised and Wechsler Adult Intelligence Scale-III
The Wechsler Intelligence Scales are the most popular method of estimating IQ in clinical settings. There have been Spanish (Escala Inteligencia de Wechsler or EIWA) and Japanese translations (Hattori & Lynn, 1997) as well as adaptations for British and for Canadian subjects (Pugh & Boer, 1991). The Wechsler Adult Intelligence Scale-Revised (WAIS-R; Wechsler, 1981) is, as its name implies, a revised form of the Wechsler Adult Intelligence Scale, which was first published in 1955. There were two main reasons the original version was revised. First, some of the items on the WAIS had become dated and were replaced with more contemporary items. An attempt was also made to make the test more culturefair by including items related to black people and black history. Whether these attempts succeeded is an empirical question. Second, with the passage of three decades, the norms for the WAIS were unlikely to describe deviation intelligence. Scores could be interpreted as deviation IQs from the original sample, not from the general contemporary population.
