Each subtest score is tallied and calculated with respect to non-normal or brain-damaged norms.
Others employ the WAIS-R NI ( Wechsler Adult Intelligence Scale-Revised as a Neuropsychological Instrument), another measure published by Harcourt. For example, digit span may be used to get a sense of attentional difficulties. Some neuropsychologists use the technique on people suffering brain damage as it leads to links with which part of the brain has been affected, or use specific subtests in order to get an idea of the extent of the brain damage. Intelligence tests also are used in populations with psychiatric illness or brain injury, though some regard this use as controversial.

The Wechsler Abbreviated Scale of Intelligence (WASI) uses vocabulary, similarities, block design and matrix reasoning subtests similar to those of the WAIS to provide an estimate of full scale IQ in about 30 minutes. For persons under 16, the Wechsler Intelligence Scale for Children ( WISC, 6-16 yrs) and the Wechsler Preschool and Primary Scale of Intelligence ( WPPSI, 2 1/2-7yrs, 3mos) are used as alternative measures of intelligence.Ī short, four-subtest version of the battery has recently been released, allowing clinicians to form a validated estimate of verbal, performance and full scale IQ in a shorter amount of time. It is an intelligence measure that is appropriate for use with those individuals ages 16-89 years of age (this is an expanded age range for adults 74-89, reflecting the increased average life expectancy). The WAIS-III is a version of the WAIS published in 1997 and has been superceded by the current version, WAIS-IV published in 2008.
