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

    Answer: Nonverbal Index

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

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

    Answer: Receptive vocabulary and expressive vocabulary

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

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

    Answer: General Ability Index

    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.

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

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

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

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

    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).

  6. Which clinical finding would most likely prompt an examiner to interpret the Nonverbal Index instead of the Full Scale IQ?

    Answer: The child has a severe speech-language impairment affecting verbal test performance

    When a child has a severe language impairment, the NVI provides a more valid estimate of cognitive ability by minimizing the verbal demands that would otherwise suppress scores.

  7. What is the clinical significance of a notably high Vocabulary Acquisition Index (VAI) score relative to a child's other index scores?

    Answer: It may indicate strong vocabulary development, possibly reflecting an enriched language environment

    A high VAI relative to other scores may suggest strong vocabulary knowledge, potentially reflecting a language-rich home environment or early literacy exposure.
