Wechsler Test Cognitive Assessment in Special Populations

Question 1

When administering Wechsler tests to individuals who are blind or have severe visual impairments, which adaptation is most appropriate?

Accepted Answer

Focus on verbally-administered subtests and use tactile alternatives where available, omitting subtests requiring vision

Answer

For individuals with severe visual impairment, only auditory/verbal subtests can be validly administered; visual subtests should be omitted with notation of limitations, and scores should be interpreted using available verbal composites only.

Question 2

For a child with autism spectrum disorder (ASD) who has significant language impairment, which Wechsler composite is most appropriate as the primary ability estimate?

Accepted Answer

Nonverbal Index (NVI)

Answer

The Nonverbal Index (NVI) is recommended for individuals with significant language impairments as it does not require verbal responses, providing a more valid estimate of reasoning ability independent of language.

Question 3

When assessing cognitive abilities in an individual with significant hearing loss, which Wechsler subtest type should be avoided without special accommodations?

Accepted Answer

Verbally-administered subtests requiring auditory discrimination

Answer

Verbally-administered subtests (Vocabulary, Similarities, Digit Span, etc.) require auditory perception and may be invalid for individuals with significant hearing loss without appropriate accommodations such as signing or communication boards.

Question 4

In gifted evaluations using the WISC-V, what is the primary ceiling effect concern?

Accepted Answer

The WISC-V's maximum scaled scores (19) may not adequately differentiate the highest level performers, particularly on individual subtests

Answer

Ceiling effects occur when gifted children achieve maximum or near-maximum raw scores, preventing the test from fully capturing the upper range of their abilities, particularly on individual subtests with maximum scaled scores of 19.

Question 5

Which accommodation is appropriate for an individual with severe ADHD taking the WAIS-IV to ensure a valid assessment?

Accepted Answer

Administering in shorter sessions with breaks to manage attention and fatigue, and documenting any accommodations

Answer

Administering in shorter sessions with structured breaks to manage attentional fatigue is an appropriate accommodation that preserves standardization while addressing the attentional demands of a lengthy evaluation.
