WPPSI Ancillary Index Scores 2

Question 1

For which child population is the Nonverbal Index (NVI) particularly recommended?

Accepted Answer

Children with language impairments, hearing loss, or limited English proficiency

Answer

The NVI is especially useful for children with language-based disabilities, hearing impairments, or those who are English language learners, as it minimizes verbal demands.

Question 2

Which primary indexes contribute subtests to the General Ability Index (GAI)?

Accepted Answer

Verbal Comprehension Index, Visual Spatial Index, and Fluid Reasoning Index

Answer

The GAI draws subtests from the VCI (Similarities, Vocabulary), VSI (Block Design, Object Assembly), and FRI (Matrix Reasoning, Picture Concepts).

Question 3

What does the Cognitive Proficiency Index (CPI) primarily assess?

Accepted Answer

Cognitive efficiency including working memory and processing speed

Answer

The CPI measures cognitive efficiency by combining working memory subtests (Picture Memory, Zoo Locations) and processing speed subtests (Bug Search, Cancellation).

Question 4

When would a clinician prefer to report the GAI rather than the FSIQ?

Accepted Answer

When there is a significant discrepancy between higher-order abilities and cognitive efficiency

Answer

The GAI is preferred over the FSIQ when there is a meaningful GAI-CPI discrepancy, suggesting the FSIQ may not accurately represent the child's cognitive potential.

Question 5

How does the NVI for ages 2:6–3:11 differ from the NVI for ages 4:0–7:7?

Accepted Answer

The younger age NVI includes only three subtests: Block Design, Picture Memory, and Object Assembly

Answer

For ages 2:6–3:11, the NVI includes only three subtests (Block Design, Picture Memory, Object Assembly), while the older age group NVI includes six subtests.
