  1. What is the primary purpose of the Vocabulary Acquisition Index (VAI) on the WPPSI-IV?

    Answer: To assess receptive and expressive vocabulary

    The VAI is specifically designed to measure both receptive vocabulary (Receptive Vocabulary subtest) and expressive vocabulary (Picture Naming subtest).

  2. Which two subtests comprise the Vocabulary Acquisition Index (VAI)?

    Answer: Receptive Vocabulary and Picture Naming

    The VAI consists of Receptive Vocabulary (measuring understanding of words) and Picture Naming (measuring expressive vocabulary).

  3. What is the primary purpose of the Nonverbal Index (NVI) on the WPPSI-IV?

    Answer: To provide an intelligence estimate that minimizes verbal demands

    The NVI provides a measure of general cognitive ability while minimizing the need for verbal instructions and verbal responses, making it useful for children with language barriers or hearing impairments.

  4. For ages 4:0–7:7, how many subtests comprise the Nonverbal Index (NVI)?

    Answer: 6

    For ages 4:0–7:7, the NVI includes six subtests: Block Design, Object Assembly, Matrix Reasoning, Picture Concepts, Bug Search, and Cancellation.

  5. Which cognitive processes does the General Ability Index (GAI) intentionally exclude compared to the Full Scale IQ?

    Answer: Working memory and processing speed

    The GAI excludes working memory and processing speed subtests, providing a purer measure of higher-level cognitive abilities (verbal comprehension, visual spatial, and fluid reasoning).

  6. What does a significant discrepancy between the General Ability Index (GAI) and the Cognitive Proficiency Index (CPI) suggest clinically?

    Answer: There may be a meaningful difference between higher-order cognitive abilities and cognitive efficiency

    A significant GAI-CPI discrepancy suggests the child's higher-order reasoning abilities differ meaningfully from their cognitive efficiency, which may indicate processing difficulties.

  7. Which subtests make up the Cognitive Proficiency Index (CPI) on the WPPSI-IV?

    Answer: Picture Memory, Zoo Locations, Bug Search, and Cancellation

    The CPI consists of the working memory subtests (Picture Memory and Zoo Locations) and the processing speed subtests (Bug Search and Cancellation).
