Wechsler Test Wechsler FSIQ and Index Score Interpretation 3 — Questions and Answers
Question 1: Which WISC-V index was newly separated from Perceptual Reasoning to distinguish spatial from fluid abilities?
- Processing Speed Index
- Visual Spatial Index (Correct answer)
- Working Memory Index
- Verbal Comprehension Index
Correct answer: Visual Spatial Index
The WISC-V split the old Perceptual Reasoning Index into the Visual Spatial Index and Fluid Reasoning Index.
Question 2: A FSIQ score of 100 corresponds to approximately which percentile rank?
- 16th percentile
- 50th percentile (Correct answer)
- 84th percentile
- 98th percentile
Correct answer: 50th percentile
A FSIQ of 100 equals the mean, which is the 50th percentile.
Question 3: The Fluid Reasoning Index (FRI) best measures which capacity?
- Recall of learned facts
- Novel problem solving and inductive reasoning (Correct answer)
- Handwriting speed
- Vocabulary depth
Correct answer: Novel problem solving and inductive reasoning
Fluid reasoning involves detecting relationships and solving novel problems without relying on prior knowledge.
Question 4: Approximately what FSIQ score marks the 98th percentile, the common threshold for gifted programs?
- 110
- 120
- 130 (Correct answer)
- 140
Correct answer: 130
A FSIQ near 130 falls at roughly the 98th percentile, often used as a giftedness cutoff.
Question 5: Before interpreting the FSIQ, a clinician should first check whether the index scores are:
- Above 100
- Unitary (not too discrepant from one another) (Correct answer)
- All below average
- Converted to scaled scores
Correct answer: Unitary (not too discrepant from one another)
The FSIQ is most interpretable when the underlying indexes are reasonably consistent (unitary).
Question 6: A Processing Speed Index of 70 places an examinee in which classification?
- Average
- Low Average
- Borderline / Extremely Low boundary (Correct answer)
- High Average
Correct answer: Borderline / Extremely Low boundary
A score of 70 sits at the boundary between Borderline and Extremely Low, two standard deviations below the mean.
Question 7: Which pair of index scores would the GAI rely on most while minimizing the impact of speed-related deficits?
- Processing Speed and Working Memory
- Verbal Comprehension and Visual Spatial/Fluid Reasoning (Correct answer)
- Working Memory and Verbal Comprehension
- Processing Speed and Verbal Comprehension
Correct answer: Verbal Comprehension and Visual Spatial/Fluid Reasoning
The GAI emphasizes verbal and reasoning abilities while excluding processing speed and working memory.
