  1. A clinician notes a 20-point discrepancy between a patient's Verbal Comprehension Index and Perceptual Reasoning Index. What is the most appropriate clinical interpretation?

    Answer: The FSIQ may be less interpretable and index-level analysis is warranted

    A large index discrepancy suggests the FSIQ masks meaningful ability differences, so interpretation should shift to the index scores.

  2. Which WAIS-IV index is considered most sensitive to the effects of anxiety, distractibility, and attentional problems during testing?

    Answer: Working Memory Index

    The Working Memory Index taxes sustained attention and concentration, making it vulnerable to anxiety and distractibility.

  3. The General Ability Index (GAI) is often used clinically because it:

    Answer: Minimizes the influence of Working Memory and Processing Speed

    The GAI combines Verbal Comprehension and Perceptual Reasoning subtests, reducing the impact of Working Memory and Processing Speed.

  4. A patient with a traumatic brain injury shows intact VCI and PRI but markedly low Processing Speed Index. This pattern most likely reflects:

    Answer: Preserved reasoning with reduced cognitive efficiency

    Reasoning abilities can remain intact while processing speed drops, a common finding after brain injury.

  5. When a clinician suspects a subtest score was affected by a broken pencil or examiner error, the best practice is to:

    Answer: Document the circumstance and interpret that subtest cautiously

    Testing irregularities should be documented and the affected score interpreted with appropriate caution.

  6. The Cognitive Proficiency Index (CPI) combines which two indexes?

    Answer: Working Memory and Processing Speed

    The CPI is formed from Working Memory and Processing Speed, reflecting cognitive efficiency.

  7. Base rate data in WAIS-IV interpretation is most useful for:

    Answer: Determining how unusual a score discrepancy is in the population

    Base rates indicate how frequently a given discrepancy occurs, helping judge its clinical rarity.
