✍️ Sample WAIS Questions & Answers
1. The WAIS-IV normative age bands for adults 70 and older are typically narrower (e.g., 70-74, 75-79) compared to younger bands. Why?
Narrower age bands in older adult ranges capture the accelerating rate of age-related cognitive change that occurs in later adulthood.
2. A psychologist is administering the WAIS and needs to calculate the Verbal Comprehension Index (VCI). Which combination of CORE subtests must be administered?
On the WAIS-IV, the core subtests that comprise the Verbal Comprehension Index are Similarities, Vocabulary, and Information. Comprehension is a supplemental subtest for this index.
3. On the WAIS-IV normative tables, FSIQ scores between 90 and 109 are classified as:
The Average classification spans FSIQ scores of 90–109 in the WAIS-IV classification system.
4. A clinician notes that an examinee's VCI is 108 and WMI is 88. The critical value at p < .05 is 11 points. What is the correct interpretation?
Because 20 points exceeds the critical value of 11, the difference is statistically significant; the clinician must then consult base rate tables to determine how commonly such a difference occurs in the normative sample.
5. Regression to the mean is an important consideration in WAIS-IV discrepancy analysis because:
Because of imperfect test-criterion correlations, predicting achievement from an extreme ability score (very high or very low) requires adjusting toward the mean to avoid over- or under-predicting performance.
6. A psychologist is administering the WAIS-IV. Which combination of core subtests contributes to the Perceptual Reasoning Index (PRI)?
The three core subtests that form the Perceptual Reasoning Index (PRI) on the WAIS-IV are Block Design, Matrix Reasoning, and Visual Puzzles. These tasks require visual analysis, synthesis, and nonverbal abstract problem-solving.
