Cognitive Assessment in Special Populations Flashcards

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

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

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.

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

Answer: Nonverbal Index (NVI)

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.

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

Answer: Verbally-administered subtests requiring auditory discrimination

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.

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

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

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.

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

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

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.

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

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

ID diagnosis requires deficits in both intellectual functioning (typically FSIQ ~70 or below) and adaptive behavior (conceptual, social, and practical domains)—cognitive testing alone is insufficient for diagnosis.

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

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

For ELLs, verbal Wechsler subtests assess English language ability rather than native verbal cognitive ability, potentially leading to underestimation of true verbal intelligence and distorted composite scores.

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

Answer: General Ability Index (GAI)

The GAI excludes processing speed subtests (which require writing/fine motor responses) and working memory subtests, providing a verbal and visual reasoning estimate less influenced by motor impairment.

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

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

Using age-appropriate normative bands and comparing the pattern of decline to expected age-normal trajectories ensures that pathological decline is distinguished from normal aging-related changes.

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

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

AAC device responses (speech-generating devices, letter boards) for verbal subtests and eye gaze or pointing for nonverbal items allow individuals with cerebral palsy who are nonspeaking to demonstrate their cognitive abilities.

Which Wechsler subtest modification specifically addresses the needs of examinees with fine motor deficits on the Block Design subtest?

Answer: Block Design No Time Bonus process score, administered standard but scored without time bonus points

The Block Design No Time Bonus (BDN) process score provides a measure of spatial construction accuracy that removes the speed advantage (and time bonus points), making it more appropriate when fine motor slowness is present.

In Wechsler testing of individuals with traumatic brain injury (TBI), which cognitive domain typically shows the greatest acute impairment immediately post-injury?

Answer: Attention, processing speed, and working memory

Acute TBI most commonly affects attentional systems, processing speed, and working memory due to diffuse axonal injury and frontal-subcortical pathway disruption, while crystallized verbal knowledge tends to be preserved.

When administering Wechsler tests to an individual with a documented learning disability in reading, which consideration is essential for the written expression components?

Answer: Timed written subtests (Coding) remain standardized, but the examiner should note that reading/writing-based subtests may be differentially affected by the learning disability

Wechsler administration follows standard procedures for all examinees; however, the examiner should interpret profile findings with awareness that a reading/writing disability may specifically depress written expression-related subtest performance while leaving reasoning abilities intact.

What is the primary reason Wechsler tests should be supplemented with culturally-adapted or non-language-dependent measures when assessing Native American children in traditional communities?

Answer: Cultural values, testing experience, and language differences may result in Wechsler scores that do not represent the child's actual cognitive capabilities

Cultural factors including unfamiliarity with standardized testing, different time orientation, language background, and different environmental knowledge may systematically affect Wechsler performance in ways unrelated to cognitive ability.

Which psychometric consideration is critical when re-administering a Wechsler test within one year to track cognitive change in a neurological condition?

Answer: Accounting for practice effects using test-retest reliability data and reliable change indices

Practice effects (improvement from familiarity with test content and format) must be accounted for using reliable change indices or regression-based change scores when interpreting whether observed score changes reflect true cognitive change.

When assessing a child with selective mutism using the WISC-V, which test administration approach best addresses the verbal response requirement?

Answer: Use pointing or AAC-based responses for verbal items when the child cannot speak, and report NVI or alternative composites

For children with selective mutism who cannot produce verbal responses in the testing context, pointing or AAC-based responses on verbal items, with focus on the NVI or nonverbal composites, provides a valid assessment of cognitive abilities.

In Wechsler testing of individuals with Parkinson's disease, which cognitive profile is most commonly observed?

Answer: Slowed processing speed and psychomotor retardation with relative preservation of verbal comprehension

Parkinson's disease typically produces bradyphrenia (slowed cognitive processing) most prominently reflected on processing speed and timed tasks, with verbal comprehension abilities often relatively preserved in early-moderate disease stages.

Which WISC-V composite is most appropriate for providing a valid cognitive ability estimate for a child who has experienced a recent significant disruption in formal schooling (e.g., long hospitalization, refugee status)?

Answer: Fluid Reasoning Index or Nonverbal Index

The Fluid Reasoning Index or NVI minimizes reliance on formal academic instruction and language-acquired knowledge, providing a more culturally fair and educationally unbiased estimate of cognitive ability for children with disrupted schooling.

For an individual with autism spectrum disorder (ASD) who shows a wide scatter across Wechsler subtests, which interpretive approach is most appropriate?

Answer: Interpret the profile of index scores individually and note the pattern of specific strengths and weaknesses characteristic of ASD rather than relying primarily on FSIQ

In ASD, wide scatter across Wechsler subtests is common and clinically meaningful; the FSIQ may be less interpretable, and the profile of specific cognitive strengths (often perceptual/visual) and weaknesses (often processing speed, working memory) should be described individually.

Which consideration is MOST important when interpreting Wechsler performance in an individual who was administered the test through a sign language interpreter?

Answer: The administration is non-standard and scores must be interpreted with caution, acknowledging that normative comparisons may not be valid

Using an interpreter represents a non-standard administration that deviates from the normative procedure, requiring explicit documentation and cautious interpretation, as the norms were established without interpreter mediation.
