Wechsler Intelligence Scale Test — Questions and Answers

Question 1: The Flynn effect, the observed long-term increase in IQ test scores, has a significant ethical implication for test interpretation. What is the primary concern related to this phenomenon?

Using outdated test norms can lead to an inflation of scores, potentially resulting in misdiagnosis or incorrect placement. (Correct answer)
It proves that intelligence is primarily determined by environmental factors, not genetics.
The effect is only observed in Western cultures, creating bias when tests are used internationally.
It suggests that non-verbal subtests are becoming less valid measures of intelligence over time.

Correct answer: Using outdated test norms can lead to an inflation of scores, potentially resulting in misdiagnosis or incorrect placement.

The Flynn effect shows that performance on IQ tests has been rising over decades at about three points per decade. The primary ethical implication is that if an individual is assessed using a test with old norms, their score will be artificially inflated compared to their true standing against their contemporary peers. This can lead to serious errors, such as failing to identify an intellectual disability or incorrectly placing a child in a gifted program.

Question 2: If a child scores 115 on the WMI, this is best described as:

Low Average
Average
High Average (Correct answer)
Superior

Correct answer: High Average

A score of 115 is one standard deviation above the mean, in the High Average range.

Question 3: A psychologist is evaluating a 4-year-old suspected of having a developmental language delay. Which WPPSI-IV composite best estimates cognitive ability while reducing language demands?

Verbal Comprehension Index
Nonverbal Index (Correct answer)
Vocabulary Acquisition Index
Full Scale IQ

Correct answer: Nonverbal Index

The Nonverbal Index was specifically designed to minimize verbal and cultural demands, making it ideal when language abilities may artificially depress other composite scores.

Question 4: A very low Visual Memory Index with an average Auditory Memory Index suggests difficulty primarily with:

Speech production
Reading comprehension
Visually presented information (Correct answer)
Spoken information

Correct answer: Visually presented information

A selectively low Visual Memory Index indicates specific trouble remembering visual material.

Question 5: Which combination would most likely produce a misleadingly low PSI in an otherwise capable examinee?

Familiarity with the format
Good vision and steady hands
High motivation and rest
Tremor plus test anxiety (Correct answer)

Correct answer: Tremor plus test anxiety

A motor tremor combined with anxiety can depress PSI scores despite intact cognition.

Question 6: Given that A + B = 2C and C + D = 2A,

A + C = 2D
A + C = B + D (Correct answer)
A + C = 2B
A + D = B + C

Correct answer: A + C = B + D

To find the correct relationship, add the two given equations: (A + B) + (C + D) = 2C + 2A. This simplifies to A + B + C + D = 2A + 2C. Subtracting A and C from both sides yields B + D = A + C. This matches option D, demonstrating the equivalence of the two expressions.

Question 7: On the Wechsler scales, Verbal Comprehension subtest raw scores are converted to what before combining into the index?

Percentile ranks only
Age-based scaled scores (mean 10, SD 3) (Correct answer)
Raw totals summed directly
Grade-equivalent scores

Correct answer: Age-based scaled scores (mean 10, SD 3)

Raw scores become scaled scores (mean 10, SD 3) normed by age before indexing.

Question 8: When writing a psychological report, which section typically states the purpose of the assessment?

Test results
Background information
Recommendations
Reason for referral (Correct answer)

Correct answer: Reason for referral

The Reason for Referral section establishes why the evaluation was requested.

Question 9: Why is establishing rapport important before WIAT administration?

It shortens the test arbitrarily
It changes the correct answers
It is required to score higher automatically
It helps the examinee perform at their true level (Correct answer)

Correct answer: It helps the examinee perform at their true level

Good rapport reduces anxiety so scores better reflect actual ability.

Question 10: On the WIAT, scaled standard scores typically have a mean of:

50
100 (Correct answer)
10
500

Correct answer: 100

WIAT standard scores use a mean of 100 and a standard deviation of 15.

Question 11: A client withdraws consent midway through WAIS-IV administration. The examiner should:

Respect the client's right to withdraw (Correct answer)
Force completion of the test
Bill for the full test anyway
Report partial scores as if complete

Correct answer: Respect the client's right to withdraw

Clients retain the right to withdraw from assessment, and examiners must honor that choice.

Question 12: A very large discrepancy between Vocabulary and other VCI subtests would prompt a clinician to:

Repeat only the Block Design subtest
Interpret subtest scatter cautiously rather than rely only on the composite (Correct answer)
Automatically assign a diagnosis
Discard the entire test

Correct answer: Interpret subtest scatter cautiously rather than rely only on the composite

Significant subtest scatter warns against over-interpreting the composite alone.

Question 13: How does the WIAT-4 differ from the Woodcock-Johnson Tests of Achievement (WJ-IV ACH) in terms of normative anchoring?

The WIAT-4 covers fewer academic domains than the WJ-IV
The WIAT-4 has no normative tables; WJ-IV provides all normative comparisons
The WIAT-4 uses criterion-referenced scoring while the WJ-IV uses norm-referenced scoring
The WIAT-4 is co-normed with Wechsler intelligence tests while the WJ-IV is co-normed with its own cognitive battery (WJ-IV COG) (Correct answer)

Correct answer: The WIAT-4 is co-normed with Wechsler intelligence tests while the WJ-IV is co-normed with its own cognitive battery (WJ-IV COG)

The WIAT-4 is co-normed with Wechsler intelligence tests (WISC-V, WAIS-IV), while the WJ-IV Achievement is co-normed with its own cognitive battery (WJ-IV COG), making each system internally consistent for ability-achievement comparisons.

Question 14: What is the Block Design No Time Bonus (BDn) score used for?

Assessing spatial construction accuracy independent of processing speed (Correct answer)
Measuring how quickly a child completes all block designs
Calculating the overall Perceptual Reasoning Index
Comparing motor speed to visual accuracy

Correct answer: Assessing spatial construction accuracy independent of processing speed

BDn is calculated without time-bonus points, providing a purer measure of spatial construction accuracy separated from speed.

Question 15: Individual Wechsler subtest scaled scores are reported on a scale with a mean of 10 and a standard deviation of how much?

3 (Correct answer)
15
5
10

Correct answer: 3

Subtest scaled scores have a mean of 10 and a standard deviation of 3.

Question 16: In a Wechsler report, what does it mean to describe a score as 'normative weakness' vs. 'personal weakness'?

Personal weakness indicates clinical significance; normative weakness does not
They are synonymous terms with no meaningful difference
Normative weakness = below the normative mean; personal weakness = below the individual's own mean but possibly still within normal limits (Correct answer)
Normative weakness applies only to composite scores; personal weakness applies only to subtests

Correct answer: Normative weakness = below the normative mean; personal weakness = below the individual's own mean but possibly still within normal limits

A normative weakness is a score below the population average (e.g., scaled score <8 or standard score <90), while a personal weakness is a relative weakness within the individual's profile even if it falls within the average normative range.

Question 17: When a Wechsler result conflicts with prior testing, the ethical examiner should:

Hide the discrepancy from the report
Always trust the higher score
Investigate possible reasons and report discrepancies transparently (Correct answer)
Discard the older data without comment

Correct answer: Investigate possible reasons and report discrepancies transparently

Discrepancies should be explored and disclosed rather than concealed, supporting honest and complete reporting.

Question 18: When a WAIS-IV score conflicts sharply with a patient's known real-world functioning, the clinician should first:

Consider validity factors such as effort, mood, and testing conditions (Correct answer)
Report only the test score
Assume the real-world observation is wrong
Discard functional information

Correct answer: Consider validity factors such as effort, mood, and testing conditions

Discrepancies between scores and functioning warrant reviewing validity factors before drawing conclusions.

Question 19: Which interpretation is appropriate when all five index scores are tightly clustered near 108?

The examinee likely has a learning disability
The indexes must be re-administered
The FSIQ is unreliable
The FSIQ is a strong, meaningful summary of ability (Correct answer)

Correct answer: The FSIQ is a strong, meaningful summary of ability

When indexes are consistent, the FSIQ reliably summarizes a unitary overall ability.

Question 20: What is the primary clinical use of the WAIS-IV in the assessment of intellectual disability in adults?

To predict future academic performance in adult education programs
To establish an objective measure of intellectual functioning for diagnostic criteria and adaptive supports (Correct answer)
To screen for schizophrenia spectrum disorders
To replace the Vineland Adaptive Behavior Scales

Correct answer: To establish an objective measure of intellectual functioning for diagnostic criteria and adaptive supports

The WAIS-IV provides a standardized measure of intellectual functioning used in the DSM-5 and AAIDD criteria for intellectual disability diagnosis, alongside adaptive behavior assessments.

Question 21: A psychologist suspects a 'floor effect' in a child with intellectual disability. This means:

Scores cluster at the top of the range
Practice effects inflated scores
The ceiling was reached early
The test cannot discriminate among very low abilities (Correct answer)

Correct 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.

Question 22: In a WAIS-IV administration, what is the examiner required to do if a child provides a zero-point response that might be upgraded with further questioning?

Record the response as-is and move on
Provide the correct answer as encouragement
Skip to the next subtest immediately
Query the response using standard query prompts to elicit a more complete response (Correct answer)

Correct answer: Query the response using standard query prompts to elicit a more complete response

When a response is ambiguous or may be upgradeable, the examiner must query using standardized prompts (e.g., 'Tell me more about that') to determine if the examinee can provide a scorable response.

Question 23: In which current Wechsler scale does the Object Assembly subtest appear as a supplemental subtest?

It is not used in any current Wechsler scale
WISC-V
WPPSI-IV (Correct answer)
WAIS-IV

Correct answer: WPPSI-IV

Object Assembly appears in the WPPSI-IV as a supplemental subtest for the older age band; it was dropped from the WAIS after the WAIS-R.

Question 24: In the sequence 3, 5, 8, 12, 17, what is the next number?

21
24
23 (Correct answer)
22

Correct answer: 23

The gaps increase by one each time (2,3,4,5,6), so 17 plus 6 equals 23.

Question 25: Which of the following best describes the primary purpose of using age-based normative data when scoring the Wechsler scales?

To adjust scores based on the examinee's educational background and socioeconomic status.
To determine the absolute number of items answered correctly without comparison to others.
To evaluate an individual's raw score in the context of the performance of a representative sample of their same-age peers. (Correct answer)
To compare an individual's performance only to others with the same clinical diagnosis.

Correct answer: To evaluate an individual's raw score in the context of the performance of a representative sample of their same-age peers.

Normative data is fundamental to standardized testing. It allows an examiner to convert a raw score into a standard score, which indicates how the individual performed relative to a large, representative sample of people in their specific age group.

Question 26: Which error appears in: 'me and him went to the store'?

Wrong tense
Incorrect subject pronoun case (Correct answer)
Misspelled verb
Missing period only

Correct answer: Incorrect subject pronoun case

Subjects should use 'He and I,' not object pronouns 'me and him.'

Question 27: In Wechsler report writing, when should an examiner qualify score interpretations as 'representing an underestimate of ability'?

When the examinee is from a minority background
Whenever the examinee scored below the normative mean
Only when explicitly requested by the referral source
When documented factors such as anxiety, fatigue, language barriers, or below-threshold effort likely suppressed performance below the examinee's true ability (Correct answer)

Correct answer: When documented factors such as anxiety, fatigue, language barriers, or below-threshold effort likely suppressed performance below the examinee's true ability

Score interpretations should be qualified as potential underestimates only when specific, documented factors (e.g., extreme test anxiety, illness, language barriers, failed PVTs) provide empirical or clinical basis for believing performance was suppressed.

Question 28: Before _____ was first used at Harvard in 1642, the Bachelor of Arts degree was the only one granted by American institutions for 125 years.

When
It was
Its (Correct answer)
Being

Correct answer: Its

The blank requires a possessive pronoun that refers to 'the Bachelor of Arts degree' and implicitly refers to its specific form or designation being used. While 'it was' is a more common and grammatically straightforward construction for a pronoun and verb, 'its' in this context implies 'its [form/designation]' was first used. This elliptical construction, though less common, indicates the degree's specific identity or concept was established at that time.

Question 29: Which WAIS-IV subtest was newly introduced (not in WAIS-III) to strengthen the Perceptual Reasoning domain?

Object Assembly
Picture Arrangement
Visual Puzzles (Correct answer)
Digit Symbol

Correct answer: Visual Puzzles

Visual Puzzles was added in WAIS-IV to measure nonverbal reasoning without a motor component.

Question 30: What is the mean and standard deviation of Wechsler index and FSIQ scores?

Mean 100, SD 16
Mean 10, SD 3
Mean 50, SD 10
Mean 100, SD 15 (Correct answer)

Correct answer: Mean 100, SD 15

All Wechsler composite scores use a mean of 100 and a standard deviation of 15.

Question 31: On the Wechsler scales, the Processing Speed Index is most likely to be lowered by which condition?

High verbal vocabulary
Fine-motor or attention difficulties (Correct answer)
Strong abstract reasoning
Good long-term memory

Correct answer: Fine-motor or attention difficulties

Processing Speed tasks are timed and graphomotor, so motor or attention problems can depress this index.

Question 32: In a Wechsler interpretation report, what ethical guideline applies to the description of culturally or linguistically diverse examinees' scores?

Scores should be reported with contextual qualifiers noting any cultural or linguistic factors that may affect validity and interpretation (Correct answer)
Cultural background has no effect on Wechsler test performance and needs no mention
Cultural diversity factors are only relevant for oral language subtests
Scores from culturally diverse examinees should not be reported to avoid bias

Correct answer: Scores should be reported with contextual qualifiers noting any cultural or linguistic factors that may affect validity and interpretation

Best practice requires contextualizing Wechsler scores for culturally or linguistically diverse examinees with explicit discussion of how language background, acculturation, and test normativity may affect score validity and interpretation.

Question 33: Which index score on the WAIS-IV measures speed of simple visual scanning and clerical processing?

Verbal Comprehension Index
Processing Speed Index (Correct answer)
Perceptual Reasoning Index
Working Memory Index

Correct answer: Processing Speed Index

The Processing Speed Index (PSI) measures quick, accurate visual-motor processing.

Question 34: Which WIAT-4 subtest requires the examinee to listen to passages and answer questions about them without seeing any printed text?

Reading Comprehension
Oral Expression
Listening Comprehension (Correct answer)
Word Reading

Correct answer: Listening Comprehension

Listening Comprehension requires the examinee to listen to audio-recorded passages and answer questions, measuring receptive language and auditory comprehension independent of reading ability.

Question 35: Practice effects from prior WMS-IV testing are best minimized by:

Skipping the delay tasks
Allowing adequate time between administrations (Correct answer)
Repeating the test daily
Using only immediate recall

Correct answer: Allowing adequate time between administrations

Leaving sufficient time between testings reduces inflated scores from practice effects.

Question 36: A standard score of 130 on the WIAT falls in which descriptive range?

Borderline
Below average
Very superior/well above average (Correct answer)
Average

Correct answer: Very superior/well above average

A score of 130 is two standard deviations above the mean, in the very superior range.

Question 37: In the context of the WISC-V, the Fluid Reasoning Index (FRI) and the Visual Spatial Index (VSI) are distinct. Which statement accurately describes a key difference between the primary abilities measured by these two indices?

The VSI focuses on verbal concept formation, while the FRI assesses non-verbal problem-solving.
The FRI is heavily dependent on acquired knowledge and education, while the VSI assesses innate visual acuity.
The FRI primarily measures the ability to detect underlying conceptual relationships and apply rules, while the VSI measures the ability to evaluate visual details and understand spatial relationships. (Correct answer)
The VSI is a timed measure of processing speed, whereas the FRI is an untimed measure of working memory.

Correct answer: The FRI primarily measures the ability to detect underlying conceptual relationships and apply rules, while the VSI measures the ability to evaluate visual details and understand spatial relationships.

The Fluid Reasoning Index (FRI) assesses the ability to identify the underlying rule or relationship in a visual pattern and use that reasoning to solve a problem (e.g., Matrix Reasoning, Figure Weights). The Visual Spatial Index (VSI) focuses on the ability to perceive, analyze, and synthesize visual information and understand how objects are oriented in space (e.g., Block Design, Visual Puzzles).

Question 38: WMS-IV index scores are reported on a scale with a mean of:

100 (Correct answer)
50
10
115

Correct answer: 100

Index scores use a mean of 100 and a standard deviation of 15.

Question 39: A very low PSI score with average scores on other indexes most often suggests difficulty with which area?

Speed and efficiency of visual-motor performance (Correct answer)
Fluid reasoning
Verbal comprehension
Crystallized knowledge

Correct answer: Speed and efficiency of visual-motor performance

An isolated low PSI typically points to slowed visual-motor processing efficiency rather than reasoning deficits.

Question 40: A student omits all end punctuation. This affects which scoring category?

Idea generation
Mechanics (Correct answer)
Handwriting speed
Vocabulary

Correct answer: Mechanics

Punctuation falls under writing mechanics.

Question 41: What is the primary purpose of using standardized verbatim instructions when administering Wechsler subtests?

To ensure scores can be validly compared to the norm sample (Correct answer)
To make the test easier for the examinee
To save time during administration
To allow the examiner to show expertise

Correct answer: To ensure scores can be validly compared to the norm sample

Verbatim instructions keep conditions consistent with the standardization sample, preserving the validity of normative comparisons.

Question 42: A clinician keeps detailed records of a Wechsler administration. The ethical purpose is primarily to:

Support accountability, continuity of care, and verification of findings (Correct answer)
Increase billing
Avoid talking to the client
Replace informed consent

Correct answer: Support accountability, continuity of care, and verification of findings

Accurate documentation supports professional accountability, future care, and the ability to substantiate conclusions.

Question 43: In a geriatric evaluation using the WAIS-IV, which pattern is most consistent with normal healthy aging rather than pathological cognitive decline?

Rapid progressive decline in all index scores over 6 months
Working memory performance higher than Verbal Comprehension Index
Severe decline in Vocabulary with preserved processing speed
Moderate decline in processing speed with well-preserved verbal comprehension and vocabulary (Correct answer)

Correct answer: Moderate decline in processing speed with well-preserved verbal comprehension and vocabulary

Normal healthy aging is characterized by gradual processing speed decline with relative preservation of crystallized abilities like verbal comprehension, consistent with the classic aging pattern in the psychometric literature.

Question 44: In Wechsler testing of individuals with Parkinson's disease, which cognitive profile is most commonly observed?

Progressive decline in verbal comprehension with preserved processing speed
Isolated verbal memory deficit with preserved processing speed and attention
Uniform decline across all Wechsler index scores from earliest disease stages
Slowed processing speed and psychomotor retardation with relative preservation of verbal comprehension (Correct answer)

Correct 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.

Question 45: Base rate data in WAIS-IV interpretation is most useful for:

Selecting which subtests to administer
Converting raw scores to scaled scores
Determining how unusual a score discrepancy is in the population (Correct answer)
Timing the subtests

Correct answer: Determining how unusual a score discrepancy is in the population

Base rates indicate how frequently a given discrepancy occurs, helping judge its clinical rarity.

Question 46: What does a Cognitive Proficiency Index (CPI) combine?

Verbal Comprehension and Visual Spatial
Visual Spatial and Fluid Reasoning
Fluid Reasoning and Verbal Comprehension
Working Memory and Processing Speed (Correct answer)

Correct answer: Working Memory and Processing Speed

The CPI is formed from the Working Memory and Processing Speed indexes, reflecting efficiency of information processing.

Question 47: The two short stories in Logical Memory differ from each other mainly by:

Containing different content and numbers of story units (Correct answer)
One being read silently
Being in different languages
Having no scoring

Correct answer: Containing different content and numbers of story units

Each story has its own narrative and a set number of scorable units.

Question 48: Which clinical population is Logical Memory frequently used to help evaluate?

Color blindness
Peripheral neuropathy
Suspected amnestic mild cognitive impairment or dementia (Correct answer)
Hearing loss only

Correct answer: Suspected amnestic mild cognitive impairment or dementia

Story-recall deficits are sensitive to early memory disorders like aMCI and Alzheimer's disease.

Question 49: What does a low Fluid Reasoning index score most likely indicate?

Inability to hear instructions
Weak fine motor speed
Poor vocabulary knowledge
Difficulty identifying rules and relationships in novel problems (Correct answer)

Correct answer: Difficulty identifying rules and relationships in novel problems

Fluid Reasoning reflects detecting patterns and relationships in unfamiliar tasks.

Question 50: Which statement accurately describes a key function measured by the Working Memory Index (WMI)?

It provides a pure measure of auditory processing, independent of attention.
It assesses the ability to generate creative, novel solutions to problems.
It evaluates cognitive flexibility and the ability to resequence information mentally. (Correct answer)
It measures the efficiency of retrieving information from long-term storage.

Correct answer: It evaluates cognitive flexibility and the ability to resequence information mentally.

A core component of working memory is not just holding information, but actively manipulating it. Subtests like Digit Span Sequencing and Letter-Number Sequencing directly require the examinee to mentally reorder and resequence the information presented.

Question 51: The WIAT-4 Oral Reading Fluency subtest measures which combination of skills?

Phonological awareness and blending
Vocabulary breadth and oral expression
Reading rate, accuracy, and prosody when reading connected text aloud (Correct answer)
Silent reading comprehension and speed

Correct answer: Reading rate, accuracy, and prosody when reading connected text aloud

Oral Reading Fluency assesses rate (speed), accuracy, and prosody (expression/rhythm) when the examinee reads paragraphs aloud, measuring the automaticity and quality of connected text reading.

Question 52: A practice effect on PSI subtests upon retesting usually means the score will do what?

Increase somewhat due to familiarity (Correct answer)
Decrease sharply
Become invalid permanently
Stay exactly identical

Correct answer: Increase somewhat due to familiarity

Familiarity with the format often produces a modest score increase on retesting.
