Which statistical approach is used to determine whether an individual examinee's PRI–VCI discrepancy is meaningful?
Answer: Comparing the difference to the critical value for statistical significance in the WAIS-IV normative tables
Clinicians use WAIS-IV normative tables that specify how large a difference must be to reach statistical significance (e.g., p < .05 or p < .01) based on the standardization sample.
When scoring Block Design, which type of error results in a time-bonus point being forfeited even if the design is ultimately correct?
Answer: Completing the design after the time limit expires
Block Design awards time-bonus points only for correct responses completed within specific time thresholds; exceeding the time limit forfeits any bonus.
Matrix Reasoning on the WAIS-IV differs from Raven's Progressive Matrices primarily in that it:
Answer: Uses a multiple-choice response format with a limited set of options rather than an open construction response
WAIS-IV Matrix Reasoning uses a closed multiple-choice format; Raven's has an open-ended response page of options with a different presentation style.
Which neuropsychological condition is most consistently associated with selective impairment on Block Design despite relatively intact Matrix Reasoning?
Answer: Right posterior parietal lesions
Right posterior parietal regions are critical for visuospatial construction; lesions there impair Block Design more than abstract pattern-matching tasks like Matrix Reasoning.
In the WAIS-IV standardization sample, the average PRI score for adults aged 65–69 compared to adults aged 20–24 typically shows:
Answer: A notable decline, reflecting age-related decrements in fluid reasoning
Fluid intelligence, including perceptual reasoning, typically declines with age, and WAIS-IV norms reflect lower average PRI scores in older age bands.
What is the primary purpose of including a supplemental subtest like Figure Weights in the WAIS-IV PRI?
Answer: To replace a core subtest if it was spoiled or the examinee was unable to complete it
Figure Weights can substitute for a core PRI subtest if administration was invalidated, allowing a valid composite to still be calculated.
Which aspect of Block Design performance is captured by the Block Design No Time Bonus (BDN) process score?
Answer: Spatial construction accuracy independent of processing speed
BDN scores Block Design responses as correct or incorrect without applying time-bonus points, isolating spatial construction accuracy from speed.
