  1. What is the supplemental Processing Speed subtest available on the WAIS-IV?

    Answer: Cancellation

    Cancellation is the supplemental PSI subtest on the WAIS-IV.

  2. Why are PSI subtests strictly timed?

    Answer: Because speed of performance is the construct being measured

    Timing is essential because the index measures the rate of processing itself.

  3. How might a physical motor impairment affect a PSI score?

    Answer: It can lower the score independent of actual cognitive speed

    Motor difficulties can depress PSI scores even when mental processing is intact, complicating interpretation.

  4. On the WISC-V, the Processing Speed Index is composed of which subtests?

    Answer: Coding and Symbol Search

    Like the WAIS-IV, the WISC-V PSI uses Coding and Symbol Search.

  5. A practice effect on PSI subtests upon retesting usually means the score will do what?

    Answer: Increase somewhat due to familiarity

    Familiarity with the format often produces a modest score increase on retesting.

  6. Which best describes the type of stimuli used in PSI subtests?

    Answer: Simple, repetitive visual symbols

    PSI tasks use simple, repetitive visual symbols to isolate speed rather than reasoning.

  7. What scaled-score mean and standard deviation do individual PSI subtests use?

    Answer: Mean 10, SD 3

    Wechsler subtest scaled scores have a mean of 10 and a standard deviation of 3.
