Wechsler adult intelligence scale (WAIS) refers to an individually administered measure of intelligence, intended for adults aged 16-89. The WAIS is intended to measure human intelligence reflected in both verbal and performance abilities. Dr. David Wechsler, a clinical psychologist, who authored the test believed that intelligence is a global construct, reflecting a variety of measurable skills and should be considered in the context of the overall personality. The WAIS is also administered as part of a test battery to make inferences about personality and pathology.
