Ch.9 - Assessment Flashcards
Intelligence tests measure
intellectual ability
Achievement tests measure
accomplishments in academic ares
Neuropsychological tests focus on
cognitive dysfunction; often from brain injury or illness
Charles Spearman, what did he argue about intelligence?
Spearman argued that intelligence was one single characteristic called “g”. It represented a person’s global, overall intellectual ability.
Thurstone, what did he argue about intelligence?
Intelligence is numerous distinct abilities that may not relate to each other. He was the first and the strongest to oppose Spearman.
What did Thurstone do to support his claim?
Factor analysis. Using that, he found independent factors: verbal comprehension, numerical ability, spatial reasoning and memory. This is why he said they don’t relate, because knowing someone’s score on a math test will not be indicative of their verbal comprehension.
What do Heiarchical models of intelligence combine?
The theories of Spearman and Thurstone. Says intelligence is a blend of singular and plural theories
What two types of intelligence is Cattell suggest?
Fluid intelligence and crystallized intelligence
What is fluid intelligence?
ability to reason when faced with novel problems
What is crystallized intelligence?
knowledge accumulated from life experience
What is Carroll’s 3 stratum theory?
there is g at the top, the 8 broad factors underneath, then 60+ specific abilities
forms a web
What are the 3 Wechsler IQ tests?
o Wechsler Adult Intelligence scale- fourth editions (WAIS-IV)- age 16-89
o Wechsler intelligence scale for children – fifth edition (WISC-V)-age 6-16
o Wechsler preschool and primary scale of intelligence - fourth edition (WPPSI-IV) age 2:6-7:3
What are 6 similarities among all 3 Wechsler tests?
- Yield single full-scale intelligence results
- One on one, face to face administration
- each subset is brief and beginning easy but increases in difficulty
- large amount of normative data (collection of 2000 peoples scores)
- Impressive validity and reliability
- Interpretation of the test: Full IQ scale first then getting more specific
What is within the full scale intelligence score?
1) 4-5 index scores: ex: verbal comprehension and perceptual organization
2) about a dozen specific subset scores
What is the mean for the full scale and index scores vs. the subset scores?
100 vs. 10
what is the SD for all IQ tests?
15
How is the Stanford-Binet Scales similar to the Wechsler? (3)
o Face-to-face, one-to-one administration
o Single overall IQ score, 5 factor scores, many more subset scores
o Mean score is 100 and SD is 15
The Stanford Binet test has become…
less commonly used than Wechsler tests, but still highly regarded and used
How is the Stanford Binet unlike Wechsler in some ways? (3)
o One test covers whole lifespan (ages 2-85+)
o Subsets include extensions at high and low end (useful for assessing giftedness or intellectual disability)
o Different subsets and factors
What subsets may place people from minority cultural groups at a disadvantage?
the verbal subset
What is the Flynn effect?
as generations grow, IQ gets higher and higher
What is the advantage of the universal nonverbal intelligence test-2 (UNIT-2)
It is entirely language free. No speaking necessary for test administer or test taker. All instructions are given by hand signals
What are the two drawbacks to the UNIT-2?
- only ages 5-21
- limited psychometric data
Intelligence is what a person…
CAN accomplish
Achievement is what a person…
HAS accomplished. Especially in reading, writing, spelling, math
Achievements tests typically produce standard scores that can..
be easily compared to scores from intelligence tests (eg. mean = 100)
The Wechsler Individual Achievement Test- Third Edition (WIAT-III) is for ages
4-50
ALSO:
Administered face-to-face and one-to-one
Reading, math, written language, oral language
What are some purposes of neurological testing (3)?
to make prognosis, plan rehab, determine eligibility for accommodations
Neurological tests can be…
lengthy and comprehensive; others are brief and targeted
