Final answer:
The reverse rule on the WAIS-IV is initiated when a subtest begins with an item that exceeds the examinee's capabilities. This rule is part of a broader structure designed by Wechsler to assess a range of cognitive abilities.
Step-by-step explanation:
The reverse rule on the WAIS-IV applies only when a subtest is started with an item that is too difficult for the examinee. This intelligence test is composed of various subtests designed to measure different cognitive abilities as conceptualized by David Wechsler. He viewed intelligence as a combination of various verbal and nonverbal skills and created a test structure that reflects this broad view. The WAIS-IV, being the fourth edition of the Wechsler Adult Intelligence Scale, is commonly used in psychological assessments and follows a scoring method that recognizes multiple cognitive abilities.
