Wechsler Adult Intelligence Scale
Also written as: WAIS — Wechsler Adult Intelligence Scale
A standardized intelligence test designed to measure cognitive abilities in adults and older adolescents.
Full Definition
The Wechsler Adult Intelligence Scale (WAIS) is the most widely used individual intelligence test for adults, designed to assess various aspects of cognitive functioning in individuals aged 16-90 years. The current version, WAIS-IV, provides scores for Full Scale IQ, Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index. The test consists of 10 core subtests and 5 supplemental subtests that evaluate different cognitive domains. WAIS results are commonly used for diagnostic purposes, educational planning, neuropsychological assessment, and disability evaluations. Interpretation requires specialized training in psychological assessment.
Usage
Usage note: Always specify version (WAIS-III, WAIS-IV) as scoring procedures and interpretive guidelines differ.
