The Wechsler Adult Intelligence Scale (WAIS) is designed for which age group?

The Wechsler Adult Intelligence Scale (WAIS) is specifically designed to assess the cognitive abilities of adults and older adolescents, typically ranging from ages 16 to 90. This scale provides insights into a variety of cognitive functions, including verbal comprehension, perceptual reasoning, working memory, and processing speed.

The WAIS is not suitable for younger age groups, such as preschool-aged children or middle school students, as their cognitive development and testing needs differ significantly from those of adults and older adolescents. Tests tailored for children, such as the Wechsler Intelligence Scale for Children (WISC), are more appropriate for the younger demographics, addressing their unique developmental stages and assessment requirements. Therefore, the correct answer emphasizes the WAIS's target demographic, showcasing its role in evaluating adult intelligence.
