Ravens Progressive Matrices
  • Versions
  • Raven Standard Progressive Matrices
  • average 6 to 80 year olds
  • Coloured Progressive Matrices (CPM)
  • younger children and special groups
  • Advanced Progressive Matrices (APM)
  • - above average adolescents adults
  • All three tests are measures of Spearman's g

7
Nature of g in search for factors underlying
intelligence
  • Charles Spearman
  • Observed that people who are good at one type of
    thinking or cognition tend to do well in other
    types as well
  • G factor
  • Spearmans term for a general intellectual
    ability that underlies all mental operations to
    some degree
  • Some of the correlations between subtexts are
    much higher than others
  • These other abilities Spearman named s factors
    for specific abilities

8
Advanced Progressive Matrices
  • The Advanced Progressive Matrices, or "difficult"
    level test, spreads the scores of the top 20
    percent of the population.
  • Applications include management selection
    (graduates), gifted education, and research on
    cognitive processes.
  • The APM is divided into two tests Set I, a
    wide-range booklet with 12 problems, is used as a
    practice and screening test for Set II Set II, a
    36-problem series, is for use with persons of
    above-average intellectual ability.

9
Coloured Progressive Matrices
  • Printed in several colours, the Coloured
    Progressive Matrices is an "easy" level test that
    spreads the scores of the bottom 20 percent of
    the general population.
  • It may be used with young children, mentally
    impaired adolescents, and the elderly.
  • The CPM includes the two easiest item sets from
    the Standard Progressive Matrices, plus a dozen
    additional items of similar difficulty.
  • The CPM is administered individually, although
    most children aged 8 and older can take the test
    in small groups.

10
Raven Standard Progressive Matrices (SPM)
  • Description The Standard Progressive Matrices
    (SPM) was designed to measure a persons ability
    to form perceptual relations and to reason by
    analogy independent of language and formal
    schooling, and may be used with persons ranging
    in age from 6 years to adult.
  • It is the first and most widely used of three
    instruments known as the Raven's Progressive
    Matrices.

The Regulative Theory of Temperament (RTT) - an
overview
  • Theory primarily presented by Strelau about
    twenty year ago, has undergone several changes
  • The current status of the RTT - described by nine
    postulates
  • It ascribes temperament to formal characteristics
    of behavior present since early infancy in humans
    and animals, and underline the biological
    background of temperament characteristics as well
    as their possible changes due to biologically
    determined life-span variation and individual-
    specific interaction with the environment
  • RTT underlines the functional significance of
    temperament characteristics especially under
    extreme demands

19
The Regulative Theory of Temperament (RTT) - an
overview
  • the structure of temperament is described by six
    following traits briskness, perseverance,
    sensory sensitivity, emotional reactivity,
    endurance, and activity
  • the location of RTT traits among dozens of other
    temperament and personality characteristics can
    be demonstrated by means of correlational and
    factor analytic studies
  • a theoretical model of the "temperament-stress"
    aimed at examining the functional significance of
    temperamental characteristics as postulated by
    the RTT is constructed

20
Temperament - definition
  • Temperament refers to basic, relatively stable,
    personality traits expressed mainly in the formal
    (energetic and temporal) characteristics of
    reactions and behavior. These traits are present
    from early childhood and they have their
    counterparts in animals. Primarily determined by
    inborn biological mechanisms, temperament is
    subject to changes caused by maturation and
    individual-specific genotype-environment
    interplay
  • (Strelau, 1998)

21
Postulates of RTT
  • 1. Temperament reveals itself in the formal
    characteristics of behavior. This statement,
    based on the conviction that for centuries formal
    traits of behavior have constituted the most
    frequently quoted feature that describes the
    nature of temperament, determined from the very
    beginning our way of studying temperament.

22
Briskness (BR)
  • tendency to react quickly, to keep a high tempo
    in performing activities, and to shift easily in
    response to changes in the surroundings from one
    behavior (reaction) to another

23
Perseveration (PE)
  • tendency to continue and to repeat behavior after
    cesation of stimuli (situations) evoking this
    behavior

24
Sensory Sensitivity (SS)
  • Ability to react to sensory stimuli of low
    stimulative value
  • Pertains to different modalities

25
Emotional Reactivity (ER)
  • tendency to react intensively to
    emotion-generating stimuli, expressed in high
    emotional sensitivity and in low emotional
    endurance

26
Endurance (EN)
  • ability to react adequately in situations
    demanding long-lasting or high stimulative
    activity and under intense external stimulation

27
Types of tests
  • Criterion the form of recording the examinees
    behaviour (Cattell)
  • Tests of performance
  • Behavior observations
  • Self-report

28
Tests of Performance Referred to as "Tests of
Maximal Performance" Examinees are given a
well-defined task that they try to perform
successfully. Examinee must know what he/she
must do in response to the task. The subject
exerts maximal effort to succeed. Performance
tests are designed to uncover what an individual
can do, given the specific test conditions.
Examples - Intelligence Tests, language
proficiency - Biology test, flight simulator
29
Self Report Instruments
  • - Participant is asked to report his or her
    feelings, attitudes, beliefs, values.
  • When self-report makes sense
  • Self-report relies upon the test takers
    awareness and honesty.
  • It is the best method to measure internal states
    - things only the person themselves can be aware
    of and judge.
  • People are not always good judges of their
    ability
  • Provides an estimate

30
Self Report Instruments
  • Many personality inventories such as the MMPI and
    the 16PF measures are based on self-report.
  • Clinicians include self-report measures as part
    of their initial examinations of presenting
    clients.
  • Self-Report measures are frequently subject to
    self-censorship.
  • People know their responses are being measured
    and wish to be seen in a favorable light.
    (self-serving bias)
  • Items are frequently included to measure the
    extent to which people provide socially desirable
    responses.

31
Behaviour Observation Naturalistic
observation Involves observing the subjects
behaviour and responses in a particular
context. Differs from performance tests in that
the subject does not have a single, well defined
task. The observer can record duration
intensity Examples - Examiner might observe
children interacting or an individual having a
conversation or some other social interaction. -
Companies recruit observers to pose as
salespeople to observe employees behaviors.
Subjects may be unaware they are being tested.

32
History of Test Development circa 1000 BC.
Chinese introduced written tests to help fill
civil service positions Civil Laws, Military
Affairs, Agriculture, Geography 1850 The United
States begins civil service examinations. 1885
Germans tested people for brain damage 1890
James Cattell develops a "mental test" to assess
college students . Test includes measures of
strength, resistance to pain, and reaction time.
1905 Binet-Simon scale of mental development
used to classify mentally retarded children in
France. 1914 World War I produces need in U.S.
to quickly classify incoming recruits. Army Alpha
test and Army Beta test developed. Looked at
psychopathology. 1916 Terman develops Stanford
- Binet test and develops the idea of
Intelligence Quotient
33
History of Test Development 1920 - 1940 factor
analysis, projective tests, and personality
inventories first appear. 1941-1960 vocational
interest measures developed 1961-1980 item
response theory and neuropsychological testing
developed 1980 - Present Wide spread
adaptation of computerized testing. "Smart"
Tests which can give each individual different
test items develop
34
Formal classification of tests
  • One-dimensional tests (one-scale instruments)
    interpretation in terms of trait intensity
    (quantitative diagnosis) or typological
    (qualitative diagnosis).
  • Multi-dimensional tests (multi-scales
    instruments) interpretation in terms of profile
    (model of parallel or hierarchical traits), which
    may lead to the typological or differential
    (within subject) diagnosis.

35

intensity
Average score moderate trait intensity
Low score low trait intensity
High score high trait intensity
36
Fig. 2. One-scale test scores, serving for
typological diagnosis
Test score similar to the upper group
Test score similar to the lower group
37
Typological diagnosis of one-scales scores
  • Typological (one-scale diagnosis) refers to the
    special one-type.
  • Typological diagnosis may refer also to two-types
    classification
  • abnormal (type I) normal abnormal (type
    II, opposite to type I)
  • Blocks concept of personality types, based on
    the dimension of self-control overcontrolled
    (inhibited) type vs underconstrolled (impulsive)
    type (normal type of personality is between
    clinical types).

40
Differential diagnosis of the test profile
  • Comparisons of the scales within one subject,
    like comparison between verbal IQ and nonverbal
    IQ (strictly quantitative assessment).

41
The history of well-known tests
  • 1905 Binet Simon the first intelligence
    scale
  • 1906 Heymans Wiersma the first personality
    assessment (peer-rating)
  • 1917 Woodworth the first personality inventory
    (psychopathology)
  • 1927-1934 Strong/Kuder the first vocational
    inventories

42
The history of well-known tests
  • 1939 Wechsler Wechsler-Bellevue Intelligence
    Scale (1997 - WAIS-III)
  • 1943 Hathaway McKinley Minnesota
    Multiphasic Personality Inventory (1989 - MMPI
    2)
  • 1949 Cattell 16 PF (Personality Factors)
  • 1950 - 1990 - Eysenckian inventories
  • 1990 2000 Big Five inventories (Costa
    McCrae).

  • Journal of Applied Psychology
  • Personnel Psychology
  • Journal of Consulting and Clinical Psychology.

44
Advantages and disadvantages of the tests
Tests represent the best, fairest, and the
most accurate technology available for making
many important decisions about individuals, but
at a time the psychological testing is highly
controversial (Murphy Davidshofer, 1989, p.
2).
45
Ethical (controversial) aspects of testing
  • The impact of testing on society (artificial or
    real differences, efficiency or equity, helping
    or hurting people)
  • Invasion of privacy (information about private
    life, problem of confidentiality and informed
    consent)
  • The fair use of tests (the equal availability of
    the test material testing disabled examinees).

46
Traits The gist
  • Personal (internal) rather than situational
    (external)
  • Stable rather than transitory (across time)
  • Consistent rather than inconsistent (across
    similar situations)
  • General rather than specific (across different
    situations)
  • Universal dimensions Individual differences
    (across people)

47
Traits
  • Traits broad dispositions to act in specific
    ways
  • disposition tendency (e.g., people with high
    anxiety tend to avoid threatening experiences)
  • broad abstraction (not specific instance
    adjectives (helpful) rather than verbs (help)

48
Traits
  • abstractions based on common features (e.g.,
    extraversion)
  • hypothetical can not observed/measured directly
    ? need to translate trait into something
    measurable (behavior)

49
Traits are
  • 1. Dimensional (ordering of people) not
    categorical
  • 2. Hypothetical (not observable)
  • 3. Causal (internal) or Descriptive (summaries)
  • Organized in a system
  • 5. Consistent over settings and time

50
Measuring Traits
  • Hypothetical nature of trait - can not know with
    absolute certainty measure is tapping intended
    trait
  • Many measures of same trait
  • All with error variance not due to trait
    (different types of measure have different
    sources of error)

Trait

51
Traits and individual differences attenuated by
  • Strong situational constraints
  • Trait combinations
  • Trait conflicts
  • Other traits
  • Motives
  • Temporary moods
  • Roles

52
Intelligence Tests Today
  • The Weschler Test (WAIS-IIIR)
  • 14 subtests
  • 7 subtests make up verbal intelligence
  • 6 subtests make up performance intelligence

53
The Weschler Test (WAIS-IIIR)
54
What is the WAIS measuring?
  • Verbal IQ Score
  • Measure of acquired knowledge, verbal reasoning
    and attention to verbal materials
  • Performance IQ score
  • Measure spatial processing, attentiveness to
    detail and visual motor integration

55
What is the WAIS measuring?
  • Verbal Comprehension
  • Measure of verbal acquired knowledge and verbal
    reasoning
  • Working Memory
  • Measures how one attends to, holds and processes
    information briefly.

56
What is the WAIS measuring?
  • Perceptual Organization
  • Measures spatial processing and attentiveness to
    detail
  • Processing Speed
  • Measures ability to process visual information
    quickly
