Read the first 7 Wechsler FSIQ and Index Score Interpretation flashcards as text

  1. A FSIQ of 85 falls into which Wechsler classification?

    Answer: Low Average

    A score of 85 is one standard deviation below the mean, classified as Low Average.

  2. If an examinee's WMI is much lower than their VCI and VSI, performance on which type of task is most likely affected?

    Answer: Holding and manipulating information mentally

    A low Working Memory Index predicts difficulty holding and mentally manipulating information.

  3. The Standard Error of Measurement (SEM) is used primarily to:

    Answer: Build confidence intervals around obtained scores

    The SEM quantifies measurement error and is used to construct confidence intervals around a score.

  4. Which interpretation is appropriate when all five index scores are tightly clustered near 108?

    Answer: The FSIQ is a strong, meaningful summary of ability

    When indexes are consistent, the FSIQ reliably summarizes a unitary overall ability.

  5. A difference between VCI and FRI that occurs in fewer than 10% of the population is described as:

    Answer: Statistically significant and rare (unusual)

    A discrepancy with low base rate is both statistically significant and clinically unusual.

  6. Why should a clinician avoid reporting only the FSIQ when index scatter is large?

    Answer: It can mislead by hiding meaningful ability differences

    A single FSIQ over wide scatter can misrepresent an examinee whose abilities differ greatly across domains.

  7. On the WAIS-IV, which index combines Symbol Search and Coding subtests?

    Answer: Processing Speed Index

    Symbol Search and Coding are the core subtests of the Processing Speed Index.
