What is the main purpose of standardized intelligence tests like the WAIS?

1. To measure academic achievements

2. To assess potential job performance

3. To evaluate cognitive abilities in adults and adolescents

4. To compare physical fitness levels

The correct answer is: To evaluate cognitive abilities in adults and adolescents

Standardized intelligence tests, such as the Wechsler Adult Intelligence Scale (WAIS), are primarily designed to evaluate cognitive abilities in adults and adolescents. These assessments aim to measure various cognitive functions, including reasoning, problem-solving, and comprehension skills. By identifying an individual's intellectual strengths and weaknesses, the WAIS helps professionals understand overall cognitive functioning. The focus of the WAIS on cognitive abilities distinguishes it from other forms of assessment. For instance, while measuring academic achievements could involve different aspects of education, the WAIS specifically looks at general intelligence, which can influence learning capacity but is not limited to academic success alone. Similarly, although some intelligence tests might relate to job performance within specific contexts, the WAIS does not serve as a direct measure of potential job performance. Lastly, standardized intelligence tests do not assess physical fitness levels, which is outside the realm of cognitive evaluation. Thus, the primary purpose of the WAIS is to provide insights into cognitive abilities among adults and adolescents.
