Which index is comprised of the subtests Symbol Search, Coding, and Cancellation?

1. Working Memory Index

2. Processing Speed Index

3. Verbal Comprehension Index

4. General Ability Index

The correct answer is: Processing Speed Index

The answer is identified accurately as the Processing Speed Index. This index reflects an individual's ability to quickly and accurately process simple or routine visual information. The subtests of Symbol Search, Coding, and Cancellation are specifically designed to assess these processing speed capabilities. Symbol Search measures the ability to scan and compare visual information quickly, while Coding involves translating symbols into corresponding numbers under time constraints, showcasing both speed and accuracy. Cancellation assesses how well an individual can locate and mark specific symbols among distractors, further emphasizing processing speed. In contrast, the Working Memory Index focuses on cognitive tasks that require holding and manipulating information, the Verbal Comprehension Index evaluates understanding of language-based concepts and verbal reasoning, and the General Ability Index encompasses a broader range of cognitive abilities without specifically emphasizing processing speed as its core component.
