psych Testing Exam 2 Flashcards
Edward Spearman Theory of intelligence
Two factor Approach general Factor (g) and specific factor (s)
Weight of g varies as a function of what was being measured
Ratio of general intelligence (g) to specific talent for completing a tax return (s) was 10 to 1
Ratio of general intelligence to specific talent for music was 1 to 4
Raymon Cattell’s Fluid and Crystal Intelligence (first theory with associated tests)
Fluid (Gf) intelligence(culturally free)
inately born
non verbal
Crystallized intelligence acquired as we learn and affected by out experience verbal intelligence
Gc increases with ages and GF declines as we age
John Horn theory of intelligence
There is no overarching thing there is just gf and gc
John Carrol
supports over arching g factor
Kevin McGrew
integrated models and proposed the CHC framework
WAIS
Wechsler Family of Tests are considered by many to be the gold-standard intelligence measures
Weschler thought that test measure the capacity of an individual to cope with challenges
Weschler test derived from the belief that intelligence is a singular construct MUCH LIKE SPEARMANS G
Weschler believed this capacity contained components that were interdependent.
Viewed a verbal non verbal dichotomy as two ways that intelligence could be expressed
this is like crystallized and non crystal intelligence
criticize this instrument because he thought it was too verbal in nature (this is important)
there was a need for a test that emphasized both verbal and non verbal
Indexes of the WAIS
verbal comprehension
Perceptual reasoning
Working Memory
Processing Speed
General Facts about the WAIS
Average all the subtests to find a score in any of the indexes
Processing speed Index is the most sensitive to intelligence or cognitive problems
Factor Analysis is the best way to look at the WAIS
verbal comprehension WAIS
reflelcts the ability to understand meaning of words, access factual knowledge and express information in words
REfelcts ability to work with abstract semantic information
Verbal memory abilities
Verbal fluency
SImilarities subtest (WAIS)
Test of verbal concept formation the ability to place objects and events together in a meaningful group Abilities involved Logical abstraction verbal reasoning
Vocabulary Subtest (WAIS)
test of word knowledge
Abilities involved language development word knowledge fund of information
Information Subtest(WAIS)
Knowledge an average person with average experiences should know Abilities invovled long term memory intellectual curiosity long term memory
Perceptual reasoning index
less effect by educational background than vci
Logic and reasoning necessary to solve spatial relationships
Digit Span
Evaluate short term acquired auditory memory attention Abilities assesed immediate rote recall auitory sequencing concentration attention
Neuropsychology
Study of brain behavior relationships
gives test that are sensitive to functioning in the brain
Neuropsychological testing
standardized procedures that asses and quantify brain functioning
results lead to inferences regarding the covert processes of the brain
Neuropsychological assessment
evaulation or extent of brain damages
normative/idiographic approches used
Fix Battery Approach
involves the rigid and standardized administration of a uniform group of tests
