  1. The PSI composite (index) score uses which mean and standard deviation?

    Answer: Mean 100, SD 15

    Index/composite scores follow the standard mean of 100 with an SD of 15.

  2. Which factor is LEAST likely to genuinely lower a person's processing speed performance?

    Answer: High vocabulary knowledge

    Strong vocabulary knowledge does not impair the visual-motor speed PSI measures.

  3. In a clinical profile, a large gap where PSI is much lower than Verbal Comprehension might prompt the examiner to consider what?

    Answer: Whether the Full Scale IQ adequately represents overall ability

    A wide index discrepancy can make the FSIQ less interpretable as a single summary of ability.

  4. Which everyday skill is most conceptually related to processing speed?

    Answer: Quickly proofreading a page for typos

    Rapid visual scanning like proofreading mirrors the quick perception PSI assesses.

  5. What should an examiner do if an examinee has a visual acuity problem before administering PSI subtests?

    Answer: Ensure corrective lenses are worn or note the limitation

    Uncorrected vision problems invalidate PSI results, so correction or documentation is needed.

  6. Processing speed tends to show what pattern across the adult lifespan?

    Answer: It generally declines with advancing age

    Processing speed typically declines with older age, one of the more age-sensitive abilities.

  7. Why is processing speed considered a foundational cognitive ability?

    Answer: Faster basic processing can support performance on more complex tasks

    Efficient processing speed frees resources and supports higher-order cognitive functioning.
