Which WAIS-IV subtest requires the examinee to select a picture that best completes a logical matrix?
Answer: Matrix Reasoning
Matrix Reasoning presents incomplete visual matrices and asks examinees to identify the missing piece from response options.
The PRI is considered a measure of which broad cognitive ability in the Cattell-Horn-Carroll (CHC) model?
Answer: Fluid intelligence (Gf)
PRI tasks require novel problem-solving with visual stimuli, aligning with fluid intelligence (Gf) in the CHC model.
In Block Design, what does a significantly slower completion time relative to accuracy suggest about an examinee's performance?
Answer: Intact design accuracy but possible processing speed deficit
Block Design is timed, so slow but accurate performance suggests spatial construction ability is present but execution speed is reduced.
Visual Puzzles on the WAIS-IV requires the examinee to do which of the following WITHOUT physically manipulating objects?
Answer: Mentally reassemble a completed puzzle from component pieces
Visual Puzzles assesses mental rotation and spatial synthesis by having examinees identify three pieces that reconstruct a target design.
Which finding would most strongly suggest a specific deficit in spatial visualization rather than a general PRI weakness?
Answer: Low Block Design and Visual Puzzles with average Matrix Reasoning
Selectively low spatial construction subtests (Block Design, Visual Puzzles) alongside intact abstract reasoning (Matrix Reasoning) points to a spatial-specific deficit.
On the WAIS-IV, Picture Completion was moved from a core PRI subtest to supplemental status primarily because:
Answer: It showed lower g-loadings than the three core PRI subtests
Psychometric analyses showed Picture Completion had weaker g-loadings and factor alignment compared to Block Design, Matrix Reasoning, and Visual Puzzles.
A PRI score that is significantly higher than the VCI is most commonly associated with which population or learning profile?
Answer: Individuals with language-based learning disabilities or limited English proficiency
A PRI > VCI pattern is frequently observed when verbal or language difficulties depress VCI while nonverbal reasoning remains intact.
