Cognitive Assessment: WAIS-IV Flashcards
(97 cards)
Block Design
- PRI
- ability to analyze and synthesize abstract visual stimuli
- non-verbal reasoning
- percieve accurately, analyze, synthesize, and reproduce
- visual-motor coordination
Crystallized Ability
- previously learning information
Symbol Search
- PSI
- processing speed, short term visual memory, visual-motor coordination, visual discrimination
- attention, concentration
Picture Completion
- PRI
- supplemental
- visual perceptual, perceptual organization and attention to spatial detail
- non-verbal fund of imformation
PSI
- The PSI measures the speed of mental processing of visual stimuli using tasks that require rapid recording of simple responses with a pencil.
- VCI
- verbal reasoning and verbal concept formation
- long-term memory and crystallized intelligence
- verbal compression and associative thinking
Similarities
- WMI
- rote learning, memory, attention, auditory processing, mental manipulation, and working memory
Digit Span
- PRI
- supplemental
- visual perceptual, perceptual organization and attention to spatial detail
Picture Completion
- We have good reason to believe that the adolescent is functioning in the Low Average Range or below
Both the WISC-IV and WAIS-IV have norms for 16-year-olds. In which of the following cases would the WISC-IV be the better choice?
Before beginning to administer the WAIS-IV, you should:
- give a brief but frank account of the purpose of the examination
To determine whether an individual’s performance on a given subtest is a strength or weakness, we should compare the subtest’s scaled score to the mean scaled score of ten subtests unless:
- the difference between VCI and PRI is statistically significant and very rare.
- we can be highly confident that the best estimate of ___ score falls between LL and UL.

Figure Weights
- PRI
- supplemental
- Fluid reasoning, quanititative and analogical reasoning, visual perceptual
- Similarities
- Vocabulary
- Information
- (Comprehension)
Verbal Comprehension Index Subtests
What are the advantages to tests?
- Standardized
- Quantitative
- Economical and efficient
- Best and sometimes only feasable way of collecting data
The most important reason for probing responses is to query a response when:
- it is incomplete, vague or unclear.
If a client shows a difference between VCI and PRI scores that is statistically significant at the .05 level, we can be confident that the difference:
- is not due to measurement error.
- PSI
- processing speed, short-term visual memory, psychomotor speed, visual-motor coordination
- learning abiliity, cognitive flexibility, attention, concetration, and motivation
Coding
Information
- VCI
- ability to aquire, retain, retrieve general factual knowledge
- fund of knowledge, long term memory, and retrieval, verbal comprehension and crystalized knowledge
- Block Design
- Matrix Reasoning
- Visual Puzzles

Perceptual Reasoning Index Subtests
Without knowledge of the actual reliability estimates of the following measures, which should you expect to have the higher reliability, the WAIS-IV Verbal Comprehension Index score or the Vocabulary subtest score?
- VCI score, because longer tests are generally more reliable reliability.
The PSI measures the speed of mental processing of visual stimuli using tasks that require rapid recording of simple responses with a pencil.
- Processing Speed Index
The term most equivalent to “base rate” is
- frequency of occurrence. How rare is it that you will see that difference
- PSI
- processing speed, short term visual memory, visual-motor coordination, visual discrimination
- attention, concentration
