What have been the main changes in intelligence testing as it has progressed

The Binet-Simon was the first test of intelligence, created in 1905. What were the main aspects it covered?
It was a test for children (aged 5-12 years) The focus was on Judgement, attention & reasoning
Lewis Terman took the Binet-Simon test to America and standardised. What did he neglect to do?
Whilst Terman improved the test, he neglected to ensure it had cross-cultural sensitivity

What has influenced the progress of intelligence testing since 1910? | Enhanced Cognitive Theory Leading to Better Cognitive tests Improvements in understanding of cognitive ability Better educational and clinical support & intervention |
What have been the main changes in intelligence testing as it has progressed | Theories have moved from a single theory of 'g' (SB, SB-R, SB-3) to include pairs of ability (WISC, WAIS, WISC-R, WAIS-R, SB-4), *to testing now offering a more comprehensive testing of broad and specific abilities (SB-5, WISC-III, WAIS-III, WISC-IV,) |
The Binet-Simon was the first test of intelligence, created in 1905. What were the main aspects it covered? | It was a test for children (aged 5-12 years) The focus was on Judgement, attention & reasoning |
Lewis Terman took the Binet-Simon test to America and standardised. What did he neglect to do? | Whilst Terman improved the test, he neglected to ensure it had cross-cultural sensitivity |
In 1916 the Stanford-Binet was formed. What did William Stern bring to the mix? | William Stern produced the Mental Age measure for IQ: Mental Age divided by Chronological Age x 100 = IQ thus if child performs to age IQ = 100 if 8yr old has mental age of 10 = 125 If 16 yr old has mental age of 20 = 125 *However, this process does not work with adults! |
Provide a brief history of the Stanford-Binet intelligence test | *Initially developed for children/young people 1908 - first developed by Binet-Simon 1916 - SB-1 first Stanford-Binet test 1937 - SB-2 -age extended to 22 years old -standardised & scoring standards improved 1960 - SB-3 -Deviation IQ introduced 1986 - SB-4 -Incorporated Gf, Gc, Gsm (visual reasoning, quantitative reasoning, short term memory) 2003 - SB-5 |
What are the psychometric properties of the Stanford-Binet - 5 (SB-5)? | Internal consistency Testing: r= 0.95 - 0.98 Test-Retest Reliability = r = 0.95 - 0.98 Inter-Scorer Reliability = r = ~0.90 Validity = High |
What are some of the other properties of the Stanford-Binet - 5 (SB-5)? | Developed by Lewis Terman & Maude Merill It is founded on the CHC model of intelligence It is based on verbal & non-verbal sub-sets It provides composite scores and an overall IQ score *It has excellent psychometric robustness |
What is the format of the Stanford-Binet - 5 (SB-5)? | Book 1 = routing book (starting point is gauged from the routing book) Book 2 = Non-verbal tests * Book 3 = verbal tests The Sub-tests are: -Fluid Reasoning -Knowledge -Quantitative Reasoning -Visual Processing -Working Memory |
What is the interpretation scale of the Stanford-Binet - 5 (SB-5)? | 145-160 = Very Gifted 130-144 = Gifted 120 - 130 = Superior 110-119 = High Average 90 - 109 = Average 80 - 89 = Low Average 70 - 79 = Borderline Impaired 55 - 69 = Mildly Impaired 40 - 54 = Moderately Impaired |
Provide some key developmental aspects of the Wechsler Adult intelligence Scale (WAIS-IV) | It is based on a points scale NOT an Age scale WAIS, WAIR-R, & WAIS-III: were tests of Verbal and Performance Scales organised with ascending difficulty In 2003 the WAIS IV was developed to change this The WAIS-IV is made of 10 core sub-sets and 5 supplemental sub-sets |
What are the 10 core sub-sets of the Wechsler Adult intelligence Scale (WAIS-IV) | Block Design 2. Similarities (how is summer like to winter?) 3. Digit Span (List of numbers to remember) 4. Matrix Reasoning (complete the pattern) 5. Vocabulary (what does this word mean?) 6. Arithmetic (maths) 7 Symbol Search (Match the pattern) 8 Visual Puzzles (which shapes make the big one) 9 Information (Responses to questions) 10 Coding (symbols represent letters/numbers, Processing Speed is included) |
What are the 4 indices of the Wechsler Adult intelligence Scale (WAIS-IV) and which of the 10 core sub-sets do they encompass | Perceptual Reasoning Scale -1. Block Design, 4. Matrix Reasoning, 8 Visual Puzzles Verbal Comprehension Scale -2. Similarities, 5. Vocabulary, 9 Information Working Memory Scale -3. Digit Span, 6. Arithmetic Processing Speed Scale -7 Symbol Search, 10 Coding |
What are the 5 Supplemental Subsets of the Wechsler Adult intelligence Scale (WAIS-IV) and which can be substituted with one of the 10 core sub-sets? | Letter-Number Sequencing 2. Figure Weights 3. Comprehension 4. Cancellation 5. Picture Completion *Letter-Number Sequencing (e.g. 1, 3, c, 7, have to recall the letters then the numbers still in order) can be substituted for 3. Digit Span core sub-test |
Provide some background detail of the Wechsler intelligence Scale for Children (WICS-IV) | This test is focused on the CHC Model of Intelligence The Outcomes are the same as the WAIS (Full Scale IQ, 4 sub-sets) *Standardisation is stratified & based on 2,200 6-16.11 year olds |
List the similarities between the SB-5 and the WAIS-IV | developed in 2003 normed to 2,200 people (stratified) take about same completion time Full Scale IQ &sub-tests Short forms CHC model & presence of g *Very comparable scoring generally |
The Bar-on Emotional Quotient Inventory (EQ-I) Is a measure of Emotional Intelligence, what are some key points about this test? | EQ-I comprises 133 items e.g. I am in touch with my emotions the EQ-I is not suitable for children The EQ-I Relates to potential for performance rather than actual performance The EQ-I has 15 Factorial components e.g. self regard, problem solving, stress tolerance, happiness, |
When choosing an intelligence test, what considerations will help you choose the most appropriate test? | The Sample: -young, impaired, pre-morbid? Reliability & Validity Time What do you want to achieve? *what are the Gold Standards? |
What are the WAIS-IV Sub-Tests? |
