WPPSI-IV (Wechsler Preschool and Primary Scale of Intelligence) Assessment — Questions and Answers

Question 1: A child scores highly on the Verbal Comprehension Index (VCI) but struggles significantly with the Visual Spatial Index (VSI). This pattern suggests a relative strength in:

accessing and applying acquired word knowledge. (Correct answer)
nonverbal reasoning and problem-solving.
processing speed and visual scanning.
constructing geometric designs from a model.

Correct answer: accessing and applying acquired word knowledge.

The Verbal Comprehension Index measures a child's ability to access and apply acquired word knowledge, verbalize meaningful concepts, and express themselves using words. A high score indicates strength in this area, whereas struggles with the VSI (which involves tasks like Block Design) would point to difficulties with visual-spatial skills.

Question 2: Which of the following best describes the relationship between the GAI and CPI in the WPPSI-IV?

Together they comprise all components of the Full Scale IQ (Correct answer)
The GAI and CPI are both derived from the same four subtests
The GAI measures fluid reasoning while the CPI measures crystallized intelligence
They measure identical cognitive constructs

Correct answer: Together they comprise all components of the Full Scale IQ

The GAI and CPI together account for all subtests included in the FSIQ, representing higher-order abilities and cognitive efficiency components respectively.

Question 3: Why does the WPPSI-IV use two separate age bands for administration?

Because cognitive abilities develop rapidly and different tasks are appropriate at different ages (Correct answer)
Because younger children score higher on verbal tests
Because older children need more time to complete tasks
Because the test publisher requires two separate purchases

Correct answer: Because cognitive abilities develop rapidly and different tasks are appropriate at different ages

Children ages 2:6–3:11 have different cognitive capacities than those ages 4:0–7:7. Separate age bands allow the use of developmentally appropriate subtests and stimuli for each group.

Question 4: The Processing Speed Index (PSI) is available for which age band of the WPPSI-IV?

Ages 4:0 - 7:7 only (Correct answer)
Both age bands (2:6 - 7:7)
It is an optional index for all ages
Ages 2:6 - 3:11 only

Correct answer: Ages 4:0 - 7:7 only

The Processing Speed Index (PSI) and its corresponding subtests are specifically designed for and administered to the older age band of the WPPSI-IV, which is children aged 4 years, 0 months to 7 years, 7 months.

Question 5: Which primary indexes contribute subtests to the General Ability Index (GAI)?

Fluid Reasoning Index and Cognitive Proficiency Index
Visual Spatial Index and Working Memory Index
Verbal Comprehension Index and Processing Speed Index only
Verbal Comprehension Index, Visual Spatial Index, and Fluid Reasoning Index (Correct answer)

Correct answer: Verbal Comprehension Index, Visual Spatial Index, and Fluid Reasoning Index

The GAI draws subtests from the VCI (Similarities, Vocabulary), VSI (Block Design, Object Assembly), and FRI (Matrix Reasoning, Picture Concepts).

Question 6: Which of the following subtests is a primary measure of the Verbal Comprehension Index (VCI) for a 3-year-old child taking the WPPSI-IV?

Comprehension
Receptive Vocabulary (Correct answer)
Similarities
Vocabulary

Correct answer: Receptive Vocabulary

For the younger age band (2:6-3:11), the primary subtests that constitute the Verbal Comprehension Index are Receptive Vocabulary and Information. Similarities and Vocabulary are VCI subtests for the older age band.

Question 7: The Information subtest of the WPPSI-IV primarily measures a child's:

capacity to acquire, retain, and retrieve general factual knowledge. (Correct answer)
understanding of social conventions and appropriate behavior.
ability to define words.
fluid reasoning and ability to solve novel problems.

Correct answer: capacity to acquire, retain, and retrieve general factual knowledge.

The Information subtest assesses a child's fund of general knowledge acquired from their environment and long-term memory. It involves answering questions about a broad range of topics. Defining words is assessed by the Vocabulary subtest, social understanding by the Comprehension subtest, and fluid reasoning by subtests like Matrix Reasoning.

Question 8: The Vocabulary subtest of the WPPSI primarily measures:

auditory processing skills.
verbal fluency, concept formation, word knowledge, and word usage. (Correct answer)
visual perception.
mathematical reasoning.

Correct answer: verbal fluency, concept formation, word knowledge, and word usage.

Explanation: The Vocabulary subtest assesses a child's verbal abilities, including their fluency, ability to understand and use words, and their understanding of word meanings and concepts.

Question 9: Which of the following subtests are the two primary measures used to derive the Processing Speed Index (PSI) for children in the 4:0-7:7 age band of the WPPSI-IV?

Cancellation and Symbol Search
Animal Coding and Coding
Bug Search and Cancellation (Correct answer)
Bug Search and Animal Coding

Correct answer: Bug Search and Cancellation

For the older age band (4:0-7:7) on the WPPSI-IV, the Processing Speed Index is primarily composed of the Bug Search and Cancellation subtests. Animal Coding is also a processing speed subtest but is supplemental, not primary.

Question 10: A child obtains a high score on the Fluid Reasoning Index (FRI) but an average score on the Verbal Comprehension Index (VCI). What is a likely interpretation of this pattern?

The child has a strong working memory but is slow to process visual information.
The child excels at solving novel, nonverbal problems but has less developed acquired factual knowledge or verbal reasoning skills. (Correct answer)
The child has a strong vocabulary but struggles with spatial organization and planning.
The child has strong visual-motor speed but weaker language skills.

Correct answer: The child excels at solving novel, nonverbal problems but has less developed acquired factual knowledge or verbal reasoning skills.

A high FRI score indicates strong abilities in inductive reasoning and abstract problem-solving with novel visual material. An average VCI score suggests typical development of acquired knowledge and verbal skills. This pattern points to a relative strength in nonverbal, fluid problem-solving compared to their verbal knowledge base.

Question 11: In the context of the WPPSI-IV for the 4:0-7:7 age band, which pair of subtests are both core contributors to the Verbal Comprehension Index?

Receptive Vocabulary and Information
Information and Similarities (Correct answer)
Vocabulary and Comprehension
Picture Naming and Vocabulary

Correct answer: Information and Similarities

For the older age band (4:0-7:7), the two primary, or core, subtests that comprise the Verbal Comprehension Index are Information and Similarities. Receptive Vocabulary is a primary VCI subtest for the younger age band, while Vocabulary, Comprehension, and Picture Naming are supplemental or ancillary for the VCI.

Question 12: Choose the person you should call if your house is on fire.

D
A
B (Correct answer)
C

Correct answer: B

Explanation: In case of a fire emergency, the appropriate person to call for help is a firefighter or fireman. They are trained professionals who respond to fires and other emergencies to extinguish fires and rescue people.

Question 13: There are 5 subtests on the WPPSI-IV for the _____ age band.

2:6 - 3:11 (Correct answer)
2:0 - 2:5
4:0 - 5:11
6:0 - 7:7

Correct answer: 2:6 - 3:11

Explanation: For children aged 2 years 6 months to 3 years 11 months, the WPPSI-IV includes 5 subtests designed to assess their cognitive abilities.

Question 14: The WPPSI-IV standardization sample was stratified to match the 2010 U.S. Census data. Which set of variables was essential for creating this nationally representative normative group?

The child's preschool enrollment status, family income, and number of siblings.
The child's primary language, parental marital status, and urban vs. rural residence.
The child's history of developmental milestones and parent's occupation.
Age, sex, race/ethnicity, parent education level, and geographic region. (Correct answer)

Correct answer: Age, sex, race/ethnicity, parent education level, and geographic region.

The WPPSI-IV normative sample of 1,700 children was carefully selected using a stratified proportional sampling method based on key demographic variables to ensure it was representative of the U.S. population. These variables included age, sex, race/ethnicity, parent education level (as a proxy for socioeconomic status), and geographic region.

Question 15: An examiner invalidates the Bug Search subtest for a 7-year-old and substitutes it with Cancellation to derive the Processing Speed Index (PSI). Later, the Animal Coding subtest is also spoiled. Why is the examiner prohibited from substituting another subtest for Animal Coding to calculate the PSI?

No other supplemental subtests exist for the PSI.
Only one substitution is permitted per index score. (Correct answer)
The PSI cannot be prorated under any circumstances.
Cancellation can only be used to substitute for Bug Search.

Correct answer: Only one substitution is permitted per index score.

A fundamental guideline for the WPPSI-IV is that a maximum of one substitution is allowed to derive any specific primary index score. Since one substitution has already been made for the PSI, a second one is not permissible.

Question 16: Look at the pictures in the two rows below. Choose one picture from the first row that goes with one picture from the second row.

1 and 3 (Correct answer)
2 and 3
2 and 4
1 and 4

Correct answer: 1 and 3

Explanation: In the context of mailing a letter, a stamp is placed on an envelope before it is sent. This matches the typical action of affixing a stamp to an envelope for postage.

Question 17: Which of the following is a key characteristic measured by the Visual Spatial Index on the WPPSI-IV?

The ability to access and apply acquired word knowledge.
The capacity for visual and auditory short-term memory.
The ability to evaluate visual details and construct geometric designs from a model. (Correct answer)
The speed and accuracy of visual identification and decision-making.

Correct answer: The ability to evaluate visual details and construct geometric designs from a model.

The Visual Spatial Index is specifically designed to measure a child's capacity to analyze visual details and understand spatial relationships in order to replicate geometric designs or assemble puzzles. This involves visual-spatial reasoning and the synthesis of part-whole relationships.

Question 18: A key difference in the FSIQ substitution rules between the two WPPSI-IV age bands is the total number of substitutions allowed. For a child in the younger age band (2:6-3:11), what is the maximum number of substitutions permitted to calculate the FSIQ?

One (Correct answer)
Zero
Two
The same as the older age band.

Correct answer: One

The substitution rules for the FSIQ are more restrictive for the younger age band (2:6-3:11). Only one core subtest substitution is permitted when deriving the FSIQ, in contrast to the two allowed for the 4:0-7:7 age band.

Question 19: Which two subtests on the WPPSI-IV are the primary contributors to the Visual Spatial Index (VSI)?

Block Design and Object Assembly (Correct answer)
Matrix Reasoning and Picture Concepts
Bug Search and Cancellation
Picture Memory and Zoo Locations

Correct answer: Block Design and Object Assembly

The Visual Spatial Index (VSI) on the WPPSI-IV is composed of two primary subtests: Block Design and Object Assembly. These tasks measure a child's ability to analyze and synthesize abstract visual stimuli and understand part-whole relationships.

Question 20: An examiner is reviewing a child's WPPSI-IV results and wants to evaluate the efficiency with which the child processes cognitive information. Which ancillary index score, derived from the Working Memory and Processing Speed subtests, provides this specific estimate?

Cognitive Proficiency Index (CPI) (Correct answer)
Nonverbal Index (NVI)
Vocabulary Acquisition Index (VAI)
General Ability Index (GAI)

Correct answer: Cognitive Proficiency Index (CPI)

The Cognitive Proficiency Index (CPI) is a composite score derived from the Working Memory Index (WMI) and Processing Speed Index (PSI). It is designed to estimate how efficiently a child processes cognitive information, which is crucial for tasks involving learning, problem-solving, and higher-order reasoning.

Question 21: An examiner is preparing to assess a 4-year-old child with suspected expressive language difficulties. Which Verbal Comprehension subtest on the WPPSI-IV includes items that allow for a nonverbal (pointing) response to accommodate this issue?

Picture Naming
Similarities (Correct answer)
Vocabulary
Information

Correct answer: Similarities

The WPPSI-IV was updated to include picture items in the Similarities and Comprehension subtests for the older age band (4:0-7:7) to allow children with expressive language issues to indicate their answers by pointing, thereby assessing their verbal concept formation without requiring a spoken response.

Question 22: A psychologist is evaluating a child who has trouble with tasks like completing puzzles and copying shapes. Which WPPSI-IV index score would be most relevant to understanding these specific difficulties?

Processing Speed Index (PSI)
Verbal Comprehension Index (VCI)
Visual Spatial Index (VSI) (Correct answer)
Working Memory Index (WMI)

Correct answer: Visual Spatial Index (VSI)

The Visual Spatial Index (VSI) is the most relevant score for understanding difficulties with puzzles and copying shapes. Its subtests, Block Design and Object Assembly, directly measure skills like visual-perceptual organization, nonverbal reasoning, and the ability to construct geometric designs from a model, which are all critical for these tasks.

Question 23: A 5-year-old's WPPSI-IV profile shows a VCI of 115, FRI of 118, WMI of 88, and PSI of 90. This specific pattern, where reasoning abilities are significantly higher than cognitive efficiency, most strongly suggests that the child:

possesses strong cognitive reasoning abilities that may not be fully apparent in tasks requiring significant mental efficiency. (Correct answer)
has a primary and significant deficit in nonverbal, fluid reasoning.
exhibits a globally consistent and unitary cognitive profile across all domains.
has an underlying language disorder that is depressing all cognitive functions.

Correct answer: possesses strong cognitive reasoning abilities that may not be fully apparent in tasks requiring significant mental efficiency.

This pattern shows a clear discrepancy between the indexes that contribute to the General Ability Index (VCI and FRI are High Average) and those that contribute to the Cognitive Proficiency Index (WMI and PSI are Average/Low Average). This suggests the child's strong higher-order reasoning capabilities might be masked or hampered in situations that place heavy demands on working memory or require rapid processing.

Question 24: Which animal in the picture below says “oink”?

3
1
2
4 (Correct answer)

Correct answer: 4

Explanation: Among the animals shown in the picture, the pig is the one known for making the sound "oink."

Question 25: A psychologist is assessing a 6-year-old who has difficulty with novel problem-solving and 'thinking on their feet.' A low score on which WPPSI-IV index would most directly reflect these specific difficulties?

Visual Spatial Index (VSI)
Processing Speed Index (PSI)
Verbal Comprehension Index (VCI)
Fluid Reasoning Index (FRI) (Correct answer)

Correct answer: Fluid Reasoning Index (FRI)

The Fluid Reasoning Index (FRI) specifically assesses the ability to solve new problems, make connections, and apply rules, which are core components of 'thinking on your feet' or fluid intelligence. The VCI measures verbal knowledge, the PSI measures speed, and the VSI measures nonverbal constructional abilities.

Question 26: The Fluid Reasoning Index (FRI) is administered to children in which WPPSI-IV age band?

Ages 2:6 to 3:11 only
Ages 4:0 to 7:7 only (Correct answer)
Both the 2:6-3:11 and 4:0-7:7 age bands
It is an ancillary index not tied to a specific age band

Correct answer: Ages 4:0 to 7:7 only

The Fluid Reasoning Index (FRI) is one of the five primary index scores, but it is only administered to the older age band of 4 years, 0 months to 7 years, 7 months. The assessment for the younger age band does not include the FRI.

Question 27: During the administration of the Picture Memory subtest, the examiner accidentally exposes the stimulus page for 7 seconds instead of the standard 5. What is the most appropriate course of action?

Stop the subtest and administer a supplemental subtest instead.
Spoil the item and proceed to the next one. (Correct answer)
Re-administer the item with the correct timing after a short break.
Continue the test and make a note of the timing error.

Correct answer: Spoil the item and proceed to the next one.

Standardized administration is critical for valid results. If a significant timing error occurs that could aid the child's performance, the item should be spoiled (not scored) and the examiner should move to the next item to maintain the integrity of the subtest.

Question 28: A 4-year-old child obtains a low score on the Visual Spatial Index. This could indicate difficulties with which of the following cognitive abilities?

Speed and accuracy of visual scanning and decision-making
Short-term auditory memory and attention
Visual-motor coordination, nonverbal reasoning, and understanding part-whole relationships (Correct answer)
Verbal concept formation and acquired knowledge

Correct answer: Visual-motor coordination, nonverbal reasoning, and understanding part-whole relationships

The VSI specifically measures a child's ability to evaluate visual details and understand visual-spatial relationships. The core subtests, Block Design and Object Assembly, require visual-spatial reasoning, integration of part-whole relationships, and visual-motor coordination.

Question 29: A 4-year-old child taking the Zoo Locations subtest correctly places the first animal card but incorrectly places the second animal card on an item with two cards. How should this response be scored?

2 points, as partial credit is given.
1 point, for the correctly placed card.
The item should be repeated for the child.
0 points, as the entire item must be correct. (Correct answer)

Correct answer: 0 points, as the entire item must be correct.

For the Zoo Locations subtest, the child must correctly place all the animal cards in their previously viewed locations to receive credit for the item. There is no partial credit for placing some cards correctly if others are incorrect.

Question 30: The WPPSI is ___________

an IQ test used with young children. (Correct answer)
a standardized assessment for high school students.
a test for measuring physical fitness in adults.
a personality test for teenagers.

Correct answer: an IQ test used with young children.

Explanation: The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) is specifically designed to assess the cognitive development of young children, ranging from ages 2 years 6 months to 7 years 7 months.

Question 31: Which of the following is a key administrative difference between the two primary Working Memory subtests on the WPPSI-IV, Picture Memory and Zoo Locations?

Picture Memory primarily assesses visual working memory, while Zoo Locations assesses visual-spatial working memory. (Correct answer)
Picture Memory is timed, while Zoo Locations is not.
Picture Memory uses a dauber, while Zoo Locations uses puzzle pieces.
Zoo Locations has a verbal response requirement, while Picture Memory does not.

Correct answer: Picture Memory primarily assesses visual working memory, while Zoo Locations assesses visual-spatial working memory.

Picture Memory requires the child to remember *what* pictures they saw, assessing visual working memory. Zoo Locations requires the child to remember *where* the animal cards were placed on a layout, assessing visual-spatial working memory.

Question 32: The Processing Speed subtests on the WPPSI-IV, such as Bug Search and Animal Coding, were designed to be more developmentally appropriate for young children than previous versions. A key adaptation is the use of:

A pencil and paper for fine motor practice
Abstract symbols to challenge reasoning
Complex verbal instructions
An ink dauber and engaging, colorful stimuli (Correct answer)

Correct answer: An ink dauber and engaging, colorful stimuli

The WPPSI-IV Processing Speed subtests were intentionally made more 'game-like' and child-friendly. This includes using an ink dauber, which reduces fine motor demands, and employing engaging, familiar images like bugs and animals instead of abstract symbols.

Question 33: The Matrix Reasoning subtest of the WPPSI primarily measures:

auditory processing skills.
mathematical reasoning.
visual processing and abstract, spatial perception. (Correct answer)
verbal fluency.

Correct answer: visual processing and abstract, spatial perception.

Explanation: Matrix Reasoning evaluates a child's ability to visually process and manipulate abstract patterns and shapes, assessing their spatial perception and reasoning skills. This subtest may also be influenced by factors like concentration, attention, and persistence.

Question 34: Look at the pictures below. Choose the one you read.

1 (Correct answer)
3
4
2

Correct answer: 1

Explanation: Among the pictures provided, the one that you read is the newspaper. Newspapers are printed publications containing news, articles, and other written content for reading.

Question 35: During the administration of the Block Design subtest, an examiner is assessing a child's ability to:

Identify the missing part of a picture.
Assemble puzzle pieces to form a meaningful whole.
Recreate a pictured design using colored blocks within a time limit. (Correct answer)
Recall the location of animals on a map.

Correct answer: Recreate a pictured design using colored blocks within a time limit.

The Block Design subtest specifically requires the child to view a model or a picture of a design and then use two-color blocks to replicate it within a set time. This directly assesses the ability to analyze and synthesize abstract visual stimuli.

Question 36: A 6-year-old child's WPPSI-IV scores show a Verbal Comprehension Index (VCI) of 120 and a Processing Speed Index (PSI) of 85. The Full Scale IQ (FSIQ) is calculated to be 102. Which statement represents the most accurate interpretation of these results?

The child's true ability is closer to the VCI of 120, and the PSI score should be disregarded as an outlier.
The child has a learning disability due to the 35-point difference between the VCI and PSI.
The FSIQ of 102 is the best and most reliable summary of the child's overall cognitive ability.
The General Ability Index (GAI) should be considered as a more interpretable estimate of the child's reasoning abilities. (Correct answer)

Correct answer: The General Ability Index (GAI) should be considered as a more interpretable estimate of the child's reasoning abilities.

When a large, statistically significant discrepancy exists between index scores, the FSIQ may not be a valid representation of a child's unitary cognitive ability. The General Ability Index (GAI) is an ancillary score that estimates general ability with less reliance on working memory and processing speed. In this case, with a 35-point difference, the GAI would provide a more meaningful summary of the child's verbal and nonverbal reasoning skills, as it is less affected by the lower processing speed score.

Question 37: A 5-year-old child is administered the Bug Search subtest. The task requires the child to scan a search group of bugs and mark the one that matches the target bug. This task primarily assesses which cognitive ability?

Verbal Comprehension
Working Memory
Fluid Reasoning
Visual-motor coordination and speed of visual search (Correct answer)

Correct answer: Visual-motor coordination and speed of visual search

The Bug Search subtest is designed to measure a child's speed and accuracy of visual identification, decision-making, and implementation. It specifically assesses skills like visual scanning, discrimination, and visuomotor coordination under timed conditions.

Question 38: An examiner is testing a 6-year-old and administers the Cancellation subtest. In this subtest, the child is presented with a page of pictures and asked to mark specific target images. What is a key feature of the Cancellation subtest's design?

It is an untimed task focused solely on accuracy.
The child must name each object before marking it.
It includes both a random and a structured arrangement of objects. (Correct answer)
It only uses a random arrangement of objects to assess scanning ability.

Correct answer: It includes both a random and a structured arrangement of objects.

The Cancellation subtest on the WPPSI-IV distinctively includes two items: one with a random arrangement of objects and one with a structured arrangement. This allows the examiner to gather information about how the child's performance may differ based on the visual organization of the task.

Question 39: For timed performance subtests such as Block Design or Object Assembly, when must the examiner start the stopwatch to ensure standardized administration?

Immediately after saying the last word of the instructions for the item. (Correct answer)
When the child first touches the testing materials.
After the child verbally indicates they are ready to begin.
As soon as the examiner turns the stimulus book page to the item.

Correct answer: Immediately after saying the last word of the instructions for the item.

According to the WPPSI-IV administration manual, timing for performance subtests must begin immediately after the examiner finishes reading the instructions for that specific item. This ensures that every child receives the same amount of time, which is critical for standardized scoring.

Question 40: A 5-year-old child is administered the Similarities subtest. The examiner asks, 'How are a dog and a cat alike?' This task is primarily assessing the child's:

social judgment and common-sense reasoning.
long-term memory and acquired factual knowledge.
visual-perceptual organization and nonverbal reasoning.
verbal concept formation and abstract reasoning. (Correct answer)

Correct answer: verbal concept formation and abstract reasoning.

The Similarities subtest requires the child to describe how two objects or concepts are alike, which directly measures their ability to form verbal concepts and engage in abstract thinking. Information assesses factual knowledge, Object Assembly assesses visual-perceptual skills, and Comprehension assesses social judgment.

Question 41: The Coding subtest of the WPPSI measures:

verbal comprehension.
visual-motor dexterity, associative nonverbal learning, and nonverbal short-term memory. (Correct answer)
logical thinking.
auditory processing skills.

Correct answer: visual-motor dexterity, associative nonverbal learning, and nonverbal short-term memory.

Explanation: Coding assesses a child's ability to quickly and accurately transcribe symbols according to a provided key, which involves visual-motor coordination, associative nonverbal learning, and nonverbal short-term memory.

Explanation: The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) is designed to assess the cognitive abilities of children between the ages of 2 years 6 months and 7 years 7 months.

Question 44: Look at these 2 rows of pictures. Pick one picture from the first row that goes with a picture on the second row.

2 and 6
3 and 6 (Correct answer)
1 and 4
2 and 5

Correct answer: 3 and 6

Explanation: 3 and 6 go together because they are both vegetables.

Question 45: In the Picture Concepts subtest, a child is presented with two or three rows of pictures and must select one picture from each row that shares a common characteristic. This task directly assesses which aspect of fluid reasoning?

Visual-motor integration
Knowledge of part-whole relationships
Categorical and abstract reasoning (Correct answer)
Short-term visual memory

Correct answer: Categorical and abstract reasoning

The Picture Concepts subtest requires the child to identify an underlying rule or characteristic that links disparate visual stimuli, which is a direct measure of categorical and abstract reasoning. This is a key component of the broader fluid reasoning ability.

Question 46: The Similarities subtest measures:

the ability to solve mathematical problems.
recall and repeat spoken words.
logical thinking, verbal concept formation, and verbal abstract reasoning. (Correct answer)
the ability to identify and name common objects.

Correct answer: logical thinking, verbal concept formation, and verbal abstract reasoning.

Explanation: The Similarities subtest evaluates an individual's logical thinking, their ability to form verbal concepts, and their capacity for abstract verbal reasoning.

Question 47: Look at the pictures in these boxes. The pictures in the top row go together in some way. Now look at the bottom row. Which picture do you think goes in the empty box in the same way?

4 (Correct answer)
3
2
1

Correct answer: 4

Explanation: Picture 4 goes in the box because it has the same image.

Question 48: What does a significant discrepancy between the General Ability Index (GAI) and the Cognitive Proficiency Index (CPI) suggest clinically?

The child requires subtest substitution
The FSIQ is always invalid in this scenario
The child has superior verbal abilities
There may be a meaningful difference between higher-order cognitive abilities and cognitive efficiency (Correct answer)

Correct answer: There may be a meaningful difference between higher-order cognitive abilities and cognitive efficiency

A significant GAI-CPI discrepancy suggests the child's higher-order reasoning abilities differ meaningfully from their cognitive efficiency, which may indicate processing difficulties.

Question 49: The Object Assembly subtest primarily measures visual-perceptual organization, nonverbal reasoning, and which other key ability?

Cognitive flexibility
Trial-and-error learning (Correct answer)
Auditory processing
Acquired factual knowledge

Correct answer: Trial-and-error learning

The Object Assembly subtest involves presenting a child with puzzle pieces that they must assemble into a meaningful whole. This task directly assesses visual-perceptual organization, nonverbal reasoning, and the ability to use trial-and-error to find the correct solution.

Question 50: The Block Design subtest measures an individual's ability to:

identify and name common objects.
recall and repeat spoken words.
solve mathematical problems.
analyze and synthesize an abstract design and reproduce it from colored plastic blocks. (Correct answer)

Correct answer: analyze and synthesize an abstract design and reproduce it from colored plastic blocks.

Explanation: The Block Design subtest evaluates a person's ability to understand, organize, and recreate abstract designs using colored plastic blocks, reflecting their visual-spatial and problem-solving skills.
