1. What is the primary difference between the WISC-V and the WPPSI-IV regarding intended population? → The WISC-V is normed for ages 6–16; the WPPSI-IV is normed for ages 2:6–7:7
2. How many pupils do not own any pets if there are 32 students in the classroom and 12.5% of them have at least one pet? → 28
3. On a Block Design task, if the target picture shows a 2x2 red-and-white pattern, what is the first step to reproduce it? → Analyze how many blocks and which faces match the design
4. When an examiner reports a Full Scale IQ score, they often include a 95% confidence interval. What does this interval represent? → The range of scores within which we can be 95% confident the examinee's true score lies.
5. Newer editions of the Wechsler Memory Scale add a recognition trial after delayed recall mainly to: → Distinguish retrieval failure from storage failure
6. Which supplemental WISC-V subtest asks the child to name pictures of common objects as quickly as possible? → Picture Naming
7. Processing speed tends to show what pattern across the adult lifespan? → It generally declines with advancing age
8. The most defensible clinical practice when a Full Scale IQ falls on a diagnostic cutoff is to: → Report the confidence interval and consider measurement error
9. Which WMS-IV subtest is administered in the Older Adult Battery but NOT in the standard Adult Battery? → Visual Reproduction
10. For a patient with significant hearing impairment, the clinician should be most cautious interpreting: → Digit Span and other auditory-verbal subtests
11. The WAIS-IV Letter-Number Sequencing subtest is classified as a measure of which CHC broad ability? → Short-term memory and working memory (Gsm)
12. Which two subtests compose the Visual Spatial Index (VSI) on the WISC-V? → Block Design and Visual Puzzles
13. Which pair of index scores would the GAI rely on most while minimizing the impact of speed-related deficits? → Verbal Comprehension and Visual Spatial/Fluid Reasoning
14. The Verbal Comprehension Index itself is reported on a scale with which mean and standard deviation? → Mean 100, SD 15
15. Sentence Building items typically require the examinee to: → Write a sentence that uses a given target word correctly
16. A clinician interpreting an elderly patient's below-average Processing Speed Index should remember that: → Processing speed typically declines with age and norms are age-adjusted
17. The WAIS (Wechsler Adult Intelligence Scale) was introduced as a revision of which instrument? → Wechsler-Bellevue Intelligence Scale
18. Which factor could artificially lower a Verbal Comprehension score without reflecting true ability? → Limited English proficiency or hearing impairment
19. On Verbal Paired Associates, an examinee improves across learning trials. This demonstrates: → A learning curve
20. When a hearing examinee has a severe expressive language disorder, the clinician should weight: → Nonverbal reasoning indices more in interpretation
21. When a nation transitions from an agrarian to an industrial economy, the family's views, values, structures, and roles change. → Change
22. Which WIAT-4 subtest measures the ability to express ideas verbally in response to pictures or questions? → Oral Expression
23. Which new primary index score was added in the WAIS-5 (2021) compared to the WAIS-IV? → Fluid Reasoning Index
24. The Full Scale IQ (FSIQ) on the WISC-V is composed of how many subtests? → Seven
25. Which set of letters would come after this one in the series? zone --> ynnd --> xmnc --> wlnb --> ? → vkna
26. An examinee shows VCI 115, VSI 112, FRI 118, WMI 113, but PSI 79. Which composite would best represent overall ability? → GAI, because it minimizes the depressed PSI
27. Which subtest asks the child to recall a sequence of pictures in order, contributing to the Working Memory Index? → Picture Span
28. Base rate data in WAIS-IV interpretation is most useful for: → Determining how unusual a score discrepancy is in the population
29. What does the term 'intraindividual variability' refer to in Wechsler score interpretation? → The range of performance across different subtests or indices within the same individual
30. Which environmental issue most threatens the validity of a WMS-IV memory assessment? → Frequent interruptions during delay intervals
