Cognitive Assessment in Special Populations Flashcards

When assessing a deaf examinee who communicates via sign language, which Wechsler index is most appropriate to emphasize?

Answer: Perceptual Reasoning Index

Nonverbal/perceptual reasoning subtests reduce reliance on auditory language and better reflect ability in deaf examinees.

A child with cerebral palsy has impaired motor control. Which adaptation best preserves test validity?

Answer: Use subtests with reduced motor demands and report a modified profile

Selecting low-motor subtests and documenting modifications yields a fairer estimate of cognitive ability.

For an examinee with English as a second language, a low Verbal Comprehension score may reflect:

Answer: Limited English proficiency rather than reasoning ability

Language and acculturation can depress verbal scores independent of underlying cognitive ability.

Which practice is recommended when assessing an examinee with a visual impairment?

Answer: Emphasize verbally administered subtests and avoid visual stimuli

Verbal subtests that do not require sight provide a more valid estimate for visually impaired examinees.

A psychologist suspects a 'floor effect' in a child with intellectual disability. This means:

Answer: The test cannot discriminate among very low abilities

A floor effect occurs when many items are too hard, so the test fails to differentiate low-ability levels.

When testing an elderly examinee with suspected dementia, processing speed subtests are valuable because they:

Answer: Are sensitive to cognitive slowing common in neurodegenerative decline

Processing speed often declines early in dementia, making these subtests sensitive markers.

Best practice for any nonstandard administration with a special population is to:

Answer: Clearly document deviations and interpret scores with caution

Documenting modifications and qualifying interpretation maintains ethical and valid reporting.
