  1. Which pair of core subtests forms the Working Memory Index (WMI) on the WAIS-IV?

    Answer: Digit Span and Arithmetic

    On the WAIS-IV, Digit Span and Arithmetic are the two core Working Memory subtests.

  2. On the WISC-V, which subtest replaced Arithmetic as a core Working Memory measure alongside Digit Span?

    Answer: Picture Span

    The WISC-V uses Digit Span and Picture Span as its core Working Memory subtests.

  3. What is the mean standard score for the Working Memory Index on Wechsler scales?

    Answer: 100

    All Wechsler index scores have a mean of 100 and a standard deviation of 15.

  4. A person must repeat a string of digits in the exact same order presented. Which Digit Span condition is this?

    Digit Span Forward requires repeating digits in the same order, tapping short-term auditory memory.

  5. Which cognitive ability does the Working Memory Index primarily measure?

    Answer: The ability to hold and manipulate information in mind briefly

    The WMI reflects the capacity to temporarily store and mentally work with information.

  6. The standard deviation of the Wechsler Working Memory Index is:

    Answer: 15

    Wechsler index scores use a standard deviation of 15.

  7. Digit Span Backward primarily adds which demand compared to Digit Span Forward?

    Answer: Mental manipulation of the information

    Reversing the digits requires manipulating the held information, not just storing it.
