Wechsler Test Wechsler Working Memory Index 3 — Questions and Answers
Question 1: A WMI score of 130 falls into which classification range on Wechsler scales?
- Average
- High Average
- Very Superior/Extremely High (Correct answer)
- Low Average
Correct answer: Very Superior/Extremely High
A score of 130 is two standard deviations above the mean, in the Very Superior/Extremely High range.
Question 2: Letter-Number Sequencing requires the examinee to:
- Reorder mixed letters and numbers into numerical then alphabetical order (Correct answer)
- Copy symbols quickly
- Define vocabulary words
- Assemble blocks to match a design
Correct answer: Reorder mixed letters and numbers into numerical then alphabetical order
The task involves recalling numbers in ascending order and letters in alphabetical order from a mixed string.
Question 3: Which of these is considered a supplemental (not core) Working Memory subtest on the WAIS-IV?
- Letter-Number Sequencing (Correct answer)
- Digit Span
- Arithmetic
- Vocabulary
Correct answer: Letter-Number Sequencing
Letter-Number Sequencing is a supplemental Working Memory subtest on the WAIS-IV.
Question 4: Roughly what percentage of the population scores within one standard deviation of the WMI mean (85–115)?
- About 34%
- About 50%
- About 68% (Correct answer)
- About 95%
Correct answer: About 68%
About 68% of scores fall within one standard deviation of the mean in a normal distribution.
Question 5: A large gap where WMI is much lower than the Verbal Comprehension Index may suggest:
- A relative weakness in holding information in mind despite strong verbal knowledge (Correct answer)
- Superior processing speed
- A visual-spatial strength
- Perfect attention
Correct answer: A relative weakness in holding information in mind despite strong verbal knowledge
A low WMI relative to strong verbal reasoning points to a specific working-memory weakness.
Question 6: The Arithmetic subtest loads on Working Memory because it requires:
- Mentally holding numbers while performing calculations (Correct answer)
- Reading comprehension of long passages
- Rapid symbol matching
- Rotating shapes
Correct answer: Mentally holding numbers while performing calculations
Solving word problems mentally requires keeping numbers and steps active in working memory.
Question 7: On the WISC-V, Picture Span assesses working memory using:
- Visual stimuli that must be recalled in order (Correct answer)
- Spoken digits
- Written arithmetic
- Vocabulary definitions
Correct answer: Visual stimuli that must be recalled in order
Picture Span presents pictures the child must remember and select in the correct sequence.
