Stanford-Binet and Wechsler Tests Flashcards
A 10-year-old child who has received a diagnosis of autism spectrum disorder with language impairment will most likely receive the highest score on the WISC-V’s ________ Index and lowest score on the ________ Index.
A. Fluid Reasoning; Processing Speed
B. Fluid Reasoning; Working Memory
C. Verbal Comprehension; Working Memory
D. Verbal Comprehension; Processing Speed
Answer A is correct. The WISC-V Technical and Interpretive Manual provides scores obtained by several clinical groups, including individuals with autism spectrum disorder with language impairment who obtained the highest score on the Fluid Reasoning Index and lowest score on the Processing Speed Index.
The Flynn effect refers to:
A. generational increases in IQ scores in the last century.
B. generational decreases in IQ scores in the last century.
C. individual increases in IQ scores over the lifespan in the last century.
D. individual decreases in IQ scores over the lifespan in the last century.
Answer A is correct. Because Flynn was the first to describe the increase in IQ scores from one generation to the next during the 20th century, this increase is referred to as the Flynn effect.
Which of the following SB5 subtests are used to determine the starting point for the other subtests?
A. Object Series/Matrices and Verbal Analogies
B. Object Series/Matrices and Vocabulary
C. Procedural Knowledge and Vocabulary
D. Procedural Knowledge and Verbal Analogies
Answer B is correct. Administration of the SB5 begins with two routing subtests: Object Series/Matrices and Vocabulary. Administration of the other subtests then begins at a level slightly below the level indicated by the routing subtests.
Research has found that:
A. crystallized and fluid intelligence both increase or remain stable until late adulthood.
B. crystallized and fluid intelligence both peak in early to middle adulthood.
C. crystallized intelligence peaks in early to middle adulthood, while fluid intelligence peaks in late adulthood.
D. crystallized intelligence peaks in late adulthood, while fluid intelligence peaks in early to middle adulthood.
Answer D is correct. Research has confirmed that crystallized and fluid intelligence increase during childhood and adolescence but that fluid intelligence peaks before crystallized intelligence does. The reported ages at which the two types of intelligence begin to decline vary somewhat from study to study, but there’s some consensus that fluid intelligence peaks between 30 and 40 years of age, while crystallized intelligence doesn’t peak until 60 or 70 years of age.
The Processing Speed Index of the WAIS-IV consists of which of the following subtests?
A. symbol search, digit span, and block design
B. symbol search, coding, and cancellation
C. digit span, coding, and cancellation
D. letter-number sequencing, block design, and coding
Answer B is correct. The Processing Speed Index consists of two core subtests (symbol search and coding) and one supplemental subtest (cancellation).
The WAIS-IV is appropriate for individuals ________ years of age.
A. 2 through 90
B. 8 through 85
C. 16 through 90
D. 6 through 95
Answer C is correct. The WAIS-IV is a measure of intelligence for individuals 16 through 90 years of age.
According to Flanagan and Alfonso (2017), which of the following WISC-V’s primary subtests assesses both crystallized and fluid intelligence?
A. Vocabulary
B. Similarities
C. Symbol Search
D. Matrix Reasoning
Answer B is correct. The Vocabulary and Similarities subtests are the two primary subtests of the VCI. According to Flanagan and Alfonso, Vocabulary assesses crystallized intelligence only, while Similarities assesses both crystallized and fluid intelligence. Symbol Search is one of the primary subtests of the PSI and assesses processing speed. Matrix Reasoning is one of the primary subtests of the FRI and assesses fluid intelligence.
A 68-year-old woman recently received a diagnosis of mild neurocognitive disorder due to Alzheimer’s disease. Most likely she will receive the highest score on the WAIS-IV’s __________ Index and lowest score on the __________ Index.
A. Verbal Comprehension; Perceptual Reasoning
B. Working Memory; Perceptual Reasoning
C. Verbal Comprehension; Processing Speed
D. Perceptual Reasoning; Processing Speed
Answer C is correct. For the exam, you want to be familiar with the WAIS-IV Indexes that have the lowest and highest scores for individuals in several clinical samples. Note that for many of these samples – including individuals with mild neurocognitive disorder due to Alzheimer’s disease – the highest index score is on the Verbal Comprehension Index and the lowest score is on the Processing Speed Index.
