Wechsler Adult Intelligence Scale-Revised

Wechsler Adult Intelligence Scale-Revised

The Wechsler Adult Intelligence Scale-Revised (WAIS-R), was a general test of intelligence, which David Wechsler, the test's author, defined as "the global capacity of the individual to act purposefully, to think rationally, and to deal effectively with his environment." In keeping with this definition of intelligence as an aggregate of mental aptitudes or abilities, the WAIS-R has traditionally consisted of 11 subtests divided into two parts, verbal and performance. For this study, the WAIS-R included definitions of words only. The official Spanish versions of the WAIS (EIWA) was used when appropriate.
