  32. 3 approaches to evaluate intelligence
    • psychometric
    • information-processing: how we learn and solve problems
    • cognitive: how we adapt to real-world demands
  33. 1904 Binet and Simon
    • selected to design intelligence test
    • identify intellectual defiency
  34. Binet defined intellligece as...
    • to find and maintain a definite direction/purpose
    • to make necessary adaptations to achieve that purpose
    • to engage in self-critisms and self-adjustments to your strategy
  35. Binet's principles of test construction
    • age differentiation: older children know more than younger children
    • mental age: children expected to know specific things at each age
    • general mental ability: total product of various and distinct elements of intelligence; an overall score, no subscores
  36. Spearman
    • Intelligence consists of general mental ability (g) and lots of other factors
    • difference of other factors cancel each other
  37. Factor anaylsis
    in intelligence tests, the first factor is g
  38. gF-gC Theory
    • Describes multiple forms of intelligence
    • crystallized (c): knowledge and understanding we already have e.g. facts, statistics
    • fluid (f): abilities that allow us to reason, learn, think, etc.; e.g. processing of cognitive, visual, audio info
  39. 1905 Binet-Simon Scale
    • defined intelligence and asked to measure it via problem solving
    • 30 items of increasing difficulty
    • lacked an appropriate measuring unit
    • lacked normative data
  40. 1908 Simon-Binet
    • retained age differentiation
    • created age scales; items grouped according to age level, not increasing difficulty
    • only 1 score produced
    • introduced mental age; used 2/3 benchmark
  41. 1916 Standford-Binet (Version I)
    • Developed by Terman at Standford
    • retained
    • age differentiation
    • age scale
    • mental age
    • g
    • changed; increased standardization sample, except they were all white california kids
    • added the intelligence quotient (IQ); crude calculation, has limitations
  42. 1937 Standford-Binet scale (Version II)
    • extended age range down to 2 years old
    • scoring standards/instructions improved; standardization sample larger, more diverse
    • performance intems added; e.g. copy designs, but only 25% of the test
    • equivalent forms designed
    • allows test comparison and examination of psychometric properties
    • found: reliability lower for youth and those with high IQ
    • found: standard deviation vary across age/IQ groups
    • implications: we cant compare scores from different groups
  43. 1960 Standford-Binet (Version III)
    • discriminability analysis to keep items whose score correlated highly with overall test score
    • improved: instructions for scoring/administration, added the deviation IQ-a standard score; M=100, SD=16
    • corrected for differential variability in age/IQ groups; now we could compare scores, in terms of SD's
  44. Model for the 4th and 5th editions
    • Hierarchichal model: g is at the top, crystallized abilities, fluid-analytical abilities, short-term memory
    • Thurstone promotes this multidimensional model argued intelligence is comprised if independent factors; primary mental abilites
  45. 1986 Revisions (Version IV)
    • removed age scales and replaced with point scales; all items with the same content placed together into 15 seperate tests
    • implications: test-takers obtain 15 different scores of various abilities; use these scores to calculate on overall g, calculate a content area score, use just to individual test scores
  46. The 2003 (Version 5)
    • nonverbal and verbal scales equally weighted
    • intergration of point and age scales; point scale maintained on routing test, age scles used for 8 subtests
  47. Basal
    the minimal number of correct responses is obtained, indication items are not to difficult
  48. Ceiling
    the maximum number of incorrect responses is obtained, indicating items are to difficult
  49. Psychometric properties of version 5
    • SD=15, not 16
    • new subtests added;current ones updated
    • taps extremes of intelligence
    • age range 2-85+
    • standardization sample: Nearly 8000, stratified by gender, ethnicity, region, etc.
    • reliability coefficient 7.9 multiple measures
    • evidence for content-, construct-, and criterion- validities found
  50. Wechsler
    • pointed to the role of nonintellective factors of intelligence tests
    • objected to Binet's single score
    • tested intelligence in adults; said intellect could deteriorate with age
    • used point scales instead of age scales; points assigned to each item, content area scores obtained
    • use performancce scales; subjects had to things, tests independent of language, culture and education, comparable units used to express prformance/erbal scores

    • numbers 1-9 paired with a symbol
    • you translate numbers into symbols, one by one
  67. Scoring
    • score each test by hand
    • enter scores into WAIS software program
    • progrm converts each subtest's raw score to a scaled score
    • ech subtest has a M scaled score=10 and SD=3
    • these subtest scores comprise 4 different index, content area, or composit scores
    • these scores comprise the full scale IQ (FSIQ) and the general ability index (GAI)
    • age-adjusted and reference group norms
  68. Psychometrics of the WAIS-IV
    • standardized on 2450 adults; stratified by gender, race education, geographpic region
    • high split-half test-retest reliabilites
    • SEM used to yield confidence intervals around FSIQ
    • SEM for WAIS-IV=approx. 2.5 ex. 1 sem around fsiq=68% confidence, 2=95%
    • Convergent evidence for validity, scores correlate well with score from tests of similar content.
  69. The Wechsler intelligence scale for children (WISC-IV)
    measures uintelligence of indivuduals ages 6yr-16yrs, 11 months
