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

Administer the complete standard battery with no modifications

Answer

Substitute the Wechsler Nonverbal Scale of Ability

Answer

Administer only the Coding and Symbol Search subtests in large print

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

Verbal Comprehension Index

Answer

Full Scale IQ

Answer

General Ability Index

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

Visual-spatial subtests

Answer

Processing speed subtests

Answer

Working memory subtests involving visual stimuli

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

Gifted children score below the floor of the normative scale

Answer

Gifted children are excluded from the normative sample

Answer

The WISC-V overestimates intelligence in gifted children

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

Removing all time limits on all subtests

Answer

Administering only the Verbal Comprehension subtests

Answer

Repeating all instructions three times before every item

Question 6

In the assessment of individuals with suspected intellectual disability (ID), why is adaptive behavior assessment essential alongside Wechsler cognitive testing?

Accepted Answer

DSM-5 and AAIDD require concurrent deficits in both intellectual functioning AND adaptive behavior for an ID diagnosis

Answer

Adaptive behavior tests are more accurate than Wechsler tests for measuring IQ

Answer

Adaptive behavior assessment replaces cognitive testing when scores are below 70

Answer

Adaptive behavior tests provide information about reading and math skills

Question 7

When using Wechsler tests with English language learners (ELLs), what is the most significant threat to score validity?

Accepted Answer

Verbal subtests measure English language proficiency rather than underlying cognitive ability, confounding language skill with intelligence

Answer

ELLs always score higher than native English speakers on verbal subtests

Answer

Wechsler tests are prohibited for use with ELLs by federal law

Answer

Processing speed is unaffected by language background

Question 8

Which Wechsler composite is specifically recommended for assessing cognitive ability in individuals with significant motor impairments affecting writing and manual manipulation?

Accepted Answer

General Ability Index (GAI)

Answer

Processing Speed Index

Answer

Full Scale IQ

Answer

Working Memory Index

Question 9

In assessing an older adult (age 75+) for suspected dementia using the WAIS-IV, which additional consideration is most important?

Accepted Answer

Score interpretation should reference age-appropriate norms (75–79 or 80–90 band), and decline patterns should be compared against expected age-normal trajectories

Answer

Gifted norms should be applied due to the wisdom of aging

Answer

Processing speed subtests should be omitted entirely for all adults over 70

Answer

FSIQ is always the most meaningful composite for dementia screening

Question 10

When assessing cognitive abilities in an individual with cerebral palsy who cannot speak, which response format accommodation is appropriate for WISC-V administration?

Accepted Answer

Allow augmentative and alternative communication (AAC) device responses for verbal subtests, and use pointing/eye gaze for nonverbal subtests

Answer

Administer verbal subtests by telephone

Answer

Skip all subtests and rely only on caregiver report

Answer

Administer only written paper-and-pencil formats
