Answer

Block Design

Answer

Picture Completion

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

Crystallized intelligence (Gc)

Answer

Processing speed (Gs)

Answer

Short-term memory (Gsm)

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

Strong spatial construction skills overall

Answer

Deficient working memory capacity

Answer

Superior perceptual organization

Question 4

Accepted Answer

Mentally reassemble a completed puzzle from component pieces

Answer

Identify a missing piece in an incomplete picture

Answer

Arrange cards depicting a social story in order

Answer

Match colors on blocks to a printed model

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

Uniformly low scores across all PRI subtests

Answer

Low PRI combined with low PSI

Answer

Low Matrix Reasoning with average Block Design

Question 6

On the WAIS-IV, Picture Completion was moved from a core PRI subtest to supplemental status primarily because:

Accepted Answer

It showed lower g-loadings than the three core PRI subtests

Answer

It required verbal responses unlike the other PRI tasks

Answer

It was too easy for most adult examinees

Answer

It relied heavily on crystallized knowledge

Accepted Answer

Individuals with language-based learning disabilities or limited English proficiency

Answer

Individuals with nonverbal learning disabilities

Answer

Individuals with ADHD and processing speed deficits

Answer

Individuals with high crystallized intelligence
