WAIS Perceptual Reasoning Index (PRI) 2

Question 1

Which WAIS-IV subtest requires the examinee to select a picture that best completes a logical matrix?

Accepted Answer

Matrix Reasoning

Answer

Matrix Reasoning presents incomplete visual matrices and asks examinees to identify the missing piece from response options.

Question 2

The PRI is considered a measure of which broad cognitive ability in the Cattell-Horn-Carroll (CHC) model?

Accepted Answer

Fluid intelligence (Gf)

Answer

PRI tasks require novel problem-solving with visual stimuli, aligning with fluid intelligence (Gf) in the CHC model.

Question 3

In Block Design, what does a significantly slower completion time relative to accuracy suggest about an examinee's performance?

Accepted Answer

Intact design accuracy but possible processing speed deficit

Answer

Block Design is timed, so slow but accurate performance suggests spatial construction ability is present but execution speed is reduced.

Question 4

Visual Puzzles on the WAIS-IV requires the examinee to do which of the following WITHOUT physically manipulating objects?

Accepted Answer

Mentally reassemble a completed puzzle from component pieces

Answer

Visual Puzzles assesses mental rotation and spatial synthesis by having examinees identify three pieces that reconstruct a target design.

Question 5

Which finding would most strongly suggest a specific deficit in spatial visualization rather than a general PRI weakness?

Accepted Answer

Low Block Design and Visual Puzzles with average Matrix Reasoning

Answer

Selectively low spatial construction subtests (Block Design, Visual Puzzles) alongside intact abstract reasoning (Matrix Reasoning) points to a spatial-specific deficit.
