WAIS Verbal Comprehension Index (VCI) 3 — Questions and Answers
Question 1: The Information subtest of the WAIS-IV primarily measures:
- Breadth of general factual knowledge acquired from education and environment (Correct answer)
- Ability to solve novel visual puzzles
- Speed of mental processing
- Spatial rotation skills
Correct answer: Breadth of general factual knowledge acquired from education and environment
Information assesses the range of general knowledge an individual has accumulated, reflecting educational experience and long-term memory.
Question 2: Which of the following best describes a 'qualitative' observation a clinician might record during VCI subtests?
- The examinee frequently asked for repetition of questions (Correct answer)
- The examinee scored a scaled score of 9
- The examinee completed items within time limits
- The examinee's VCI was in the Average range
Correct answer: The examinee frequently asked for repetition of questions
Qualitative observations capture behavioral process information (e.g., need for repetition, self-corrections) beyond the numerical score.
Question 3: When comparing VCI to the Processing Speed Index (PSI), a large VCI > PSI discrepancy most often reflects:
- Strong crystallized verbal knowledge relative to rapid motor/cognitive output speed (Correct answer)
- Superior fluid reasoning
- Higher working memory capacity
- Better visual-spatial integration
Correct answer: Strong crystallized verbal knowledge relative to rapid motor/cognitive output speed
VCI captures long-term verbal knowledge while PSI captures rapid decision-making speed, so VCI > PSI suggests verbal strength over speed.
Question 4: A Similarities item says 'How are liberty and justice alike?' A 0-point response would be:
- 'One is a statue and one is a court building' (Correct answer)
- 'Both are abstract concepts valued in society'
- 'Both are ideals that societies strive to protect'
- 'Both are words related to rights and fairness'
Correct answer: 'One is a statue and one is a court building'
Concrete, incidental, or incorrect responses earn 0 points; naming a physical object associated with each word rather than their shared concept earns no credit.
Question 5: The WAIS-IV VCI has normative data standardized for which age range?
- 16 to 90 years (Correct answer)
- 6 to 16 years
- 18 to 65 years
- 21 to 80 years
Correct answer: 16 to 90 years
The WAIS-IV normative sample spans ages 16:0 through 90:11, making it applicable to adolescents through older adults.
Question 6: Which factor does NOT significantly influence an examinee's VCI score?
- Fine motor coordination (Correct answer)
- Years of formal education
- Socioeconomic background
- Language exposure and bilingualism
Correct answer: Fine motor coordination
VCI subtests are verbal and require no fine motor output, so motor coordination does not affect performance.
Question 7: On the WAIS-IV, supplemental VCI subtests include:
- Word Reasoning (Correct answer)
- Letter-Number Sequencing
- Symbol Search
- Block Design
Correct answer: Word Reasoning
Word Reasoning is a supplemental VCI subtest that asks examinees to identify a concept described by increasingly specific clues.
