  1. An examinee shows VCI 115, VSI 112, FRI 118, WMI 113, but PSI 79. Which composite would best represent overall ability?

    Answer: GAI, because it minimizes the depressed PSI

    The GAI better captures intact reasoning ability when a low PSI drags down the FSIQ.

  2. What does a Cognitive Proficiency Index (CPI) combine?

    Answer: Working Memory and Processing Speed

    The CPI is formed from the Working Memory and Processing Speed indexes, reflecting efficiency of information processing.

  3. A confidence interval (e.g., 95%) is reported around a FSIQ to communicate:

    Answer: The range likely containing the true score given measurement error

    Confidence intervals express that the obtained score is an estimate subject to measurement error.

  4. Two subtests within an index differ by 5 scaled-score points. This intra-index scatter suggests the clinician should:

    Answer: Interpret that index with caution

    Significant subtest scatter within an index means the composite may not represent a single unitary ability.

  5. A FSIQ of 68 on the WAIS-IV would, with adaptive deficits, support consideration of which condition?

    Answer: Intellectual disability

    A FSIQ around 68 plus deficits in adaptive functioning is consistent with intellectual disability.

  6. Why are index-level scores often more clinically useful than the single FSIQ?

    Answer: They reveal specific cognitive strengths and weaknesses

    Index scores break global ability into domains, exposing patterns the FSIQ averages away.

  7. On the WISC-V, which five primary indexes contribute to the FSIQ?

    Answer: VCI, VSI, FRI, WMI, PSI

    The WISC-V FSIQ draws on the Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed indexes.
