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
