WPPSI Ancillary Index Scores 3

Question 1

Which ancillary index would be most appropriate for a bilingual child whose dominant language is not English?

Accepted Answer

Nonverbal Index

Answer

The NVI minimizes verbal instructions and responses, making it particularly suitable for bilingual children or English language learners tested in a non-dominant language.

Question 2

The Vocabulary Acquisition Index subtests measure which two distinct vocabulary skills?

Accepted Answer

Receptive vocabulary and expressive vocabulary

Answer

The VAI combines Receptive Vocabulary (understanding words heard) and Picture Naming (expressing vocabulary by naming pictures), assessing both receptive and expressive vocabulary.

Question 3

Which WPPSI-IV ancillary index is most analogous to the GAI found in the WISC-V?

Accepted Answer

General Ability Index

Answer

The General Ability Index serves the same purpose across both the WPPSI-IV and WISC-V—providing a cognitive ability estimate that excludes working memory and processing speed.

Question 4

When comparing the GAI to the FSIQ, what is a clinician most likely trying to determine?

Accepted Answer

Whether working memory and processing speed are artificially suppressing or inflating the FSIQ

Answer

By comparing the GAI and FSIQ, clinicians can determine whether cognitive efficiency (working memory and processing speed) is significantly impacting the overall IQ estimate.

Question 5

How many subtests comprise the General Ability Index (GAI) on the WPPSI-IV?

Accepted Answer

6

The GAI consists of six subtests: Similarities and Vocabulary (from VCI), Block Design and Object Assembly (from VSI), and Matrix Reasoning and Picture Concepts (from FRI).
