"Designed as a comprehensive test of cognitive ability for adults. Wechsler Adult Intelligence Scale-Revised (WAIS-R) is a general test of intelligence, which Wechsler 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 consists of 11 subtests divided into two parts, verbal and performance. The WAIS-R consists of six verbal subtests and five performance subtests. The verbal tests are: Information, Comprehension, Arithmetic, Digit Span, Similarities, and Vocabulary. The Performance subtests are: Picture Arrangement, Picture Completion, Block Design, Object Assembly, and Digit Symbol. The scores derived from this test are a Verbal IQ (VIQ), a Performance 1Q (PIQ), and a Full Scale IQ (FSIQ). The FSIQ is a standard score with a mean of 100 and a standard deviation of approximately 15."--From accompanying explanatory sheet.
