Psych Testing and Measure Chapter 8
Full Scale IQ
(FSIQ) score which is based on the 10 core subtests in the WAIS-IV
Arthur Otis
created a group administered form of the Stanford-Binet for the army
Lewis Terman
created the Stanford-Binet scale in 1916 and created the concept of an intelligence quotient
18
deficits in adaptive functioning and an IQ of less than 70 must be documented before age ___ for someone to be diagnosed as mentally retarded
David Wechsler
developed standardized IQ score with M=100 and SD=15
mental age
devised by Binet & Simon in 1908, it is the average age at which children achieve a particular score
55-70
IQ range needed to be diagnosed as mild retardation
40-55
IQ range needed to be diagnosed as moderately mentally retarded
25-40
IQ range needed to be diagnosed as severely mentally retarded
.6-.7
IQ test scores predict ability to succeed in school by r=
Alfred Binet
father of intelligence testing
Sir frances galton
intelligence testing was first popularized by who?
adaptive
must have deficits in _______ functioning in everyday life to be diagnosed as mentally retarded
age group
norms on the WAIS-IV are separated by _____ _____
Army Beta
one of Arthus Otis' group administered IQ tests for the army, was hte verbal version for illiterate adults or immigrants who did not speak English
research
one of the main uses for individual tests of intelligence, used to find the nature of intelligence, as a control or descriptive variable
clinical
one of the main uses for individual tests of intelligence, very common part of a larger array of tests used with a client
excellent
overall, reliability and validity indices are ______ for the Vineland
internal consistency
reliability type that was found to be high on the WAIS-IV for all subtests and composite scores for which it would be appropriate
sir frances galton
used simple measures of intelligence testing
minimal theoretical basis, cultural bias
2 main criticisms of the IQ tests, 1. no underlying construct was used to devise tests and 2. scores depend on cultural experiences and language
Peabody Picture Vocab test
3 uses for this type of intelligence test 1. screening test of verbal ability 2. measure of receptive (hearing) vocabulary 3. one part of a more comprehensive battery of cognitive processes
common characteristics
8 ______ ______ of IITs, 1. individual administration 2. require advanced training 3. wide range of age/abilities 4. need for establishing rapport 5. most use a free-response format 6. immediate scoring of items 7. administration time: about 90 mins 8. opportunity for observation
Army Alpha
One of Arthur Otis' group administered IQ tests for the army, was the nonverbal version for literate adults
scores
PPVT-4 _____= raw scores- the ceiling item number minus the number of incorrect responses. the raw score gets transformed into the standard score with an M=100 and SD=15
228, 19, 12
___# of multiple choice vocab items in ___ blocks of __ items each for the PPVT-4
reliability
_____ of PPVT-4 is test-retest: .93, internal consistency is .94, alternate form is .89
norms
_____ of the PPVT-4 are age (2:6-90 years), grade (kindergarten-12)
administration
_____ of the PPVT-4: examiner reads a word and the examinee selects from among four pictures that best represent the word, examiner establishes a basal level (lowest block) and a ceiling level (highest block)
validity
_______ of PPVT shows strong correlations with lengthier, more complicated measures of vocabulary. e.g. there is a correlation of .82 between the PPVT-4 and the Expressive Vocabulary Test
16-90
age range for the WMS-IV structure
25
an IQ of less than ____ is needed to be diagnosed as profoundly mentally retarded
bivariate distribution
sir frances galton invented this, it is a correlational procedure that he used to examine the relationship between simple measures of intelligence and social class
WAIS-IV
standard scores for this test's subtests were M=10 and SD=3, but for the FSIQ and 4 index scores it was M=100 and SD=15
Index Scores
the WAIS-IV yields four of these: the verbal comprehension, perceptual reasoning, working memory, and processing speed
index scores
the five primary ______ _____ for the WMS-IV structure are 1. auditory memory 2. visual memory 3. visual working memory 4. immediate memory 5. delayed memory
IQ
the formula for this is (MA/CA)*100
.81 to .83
the reliability for the WMS-IV for its test-retest of index scores
.74-.97
the reliability of the WMS-IV (good to excellent subtest on internal consistency)
Binet-Simon Scale
the test created in 1905 used to measure intellectual development in children
Vineland
the two differences between the _______ and IQ tests are 1. reports are from observers and 2. they are looking for typical (not maximum) performance
clinical, research
the two main uses for individual tests of intelligence
convergent
the type of validity in the WMS-IV that correlates with other memory tests
discriminative
the type of validity in the WMS-IV that is not simply a measure of g
Vineland Adaptive Behavior Scales
this is the most widely used measure of adaptive behavior, has 4 versions (survey, expanded, parent/caregiver, teacher)
2
this percentage of the population has mental retardation
factor analysis
type of reliability that was found to support the four index scores on the WAIS-IV
contrasted groups
type of validity in the WMS-IV that is sensitive to identification of groups that would be expected to have memory deficits
factor analysis
type of validity in the WMS-IV that supports the index structure
alfred binet
used complex measures of intelligence testing
