Definition
A score derived from administration of selected subtests from the third and fourth edition Wechsler Intelligence Scales designed to provide a measure of a person’s ability to process visually presented information quickly.
Current Knowledge
Wechsler Intelligence Scales (WIS): The WIS family of tests is some of the most widely used test batteries to assess general intellectual ability in adults aged 16 years or older (Wechsler Adult Intelligence Scale (WAIS)), children aged 6–16 years (Wechsler Intelligence Scale for Children (WISC)), and children aged 2–7 years (Wechsler Preschool and Primary Scale of Intelligence (WPPSI)). Since the original development of these tests (WAIS 1955; WISC 1949; WPPSI 1967), all three batteries have been revised on several occasions. The most recent revisions were published in 2012 (WPPSI-IV), 2014 (WISC-V), and 2008 (WAIS-IV).
