Wechsler Adult Intelligence Scale-Revised as a Neuropsychological Instrument WAIS-R NI has been devised for the assessment of brain injury.

The WAIS-III was designed to measure the intelligence of adults and was organized into verbal and performance scales. The WAIS-R was published in 1981. The revision consisted of developing tests with capabilities for test takers, who ranged in ages 74 to 89, and provide manuals with enhanced print to make the test more useful for people with extreme intellectual deficits (Groth-Marnat, 2003). The WAIS-R NIcan be used to assess whether the clients' level of knowledge is discrepant with his or her level of education. Another strategy is based on how material can be recognized as opposed to being recalled. As Groth-Marnat explains, "Clients might be presented with multiple-choice questions in which a greater recognition suggests that they once knew the material but now have a difficult rime retrieving information during standard recall instructions" (p. 564).
