Based on Sternberg, what does the average person view intelligence as?
- Reasoning logically
- Making connections between ideas
- Seeing all aspects of a problem
STERNBERG: people tend to think about intelligence in which 3 forms?
- Problem-solving intelligence (important in children)
- Verbal intelligence (important in young adults)
- Social intelligence (important in older adults)
When judging if a student is intelligent, what intelligence do teachers use?
- Elementary teachers: social intelligence
- High school teachers: verbal intelligence
- University teachers: problem solving intelligence
What is STERNBERG’s view on intelligence?
ability to learn from experience and adapt to environment
What is WESCHLER’s view on intelligence?
to understand and adjust to the world around us
What is O’REILLY and CARR’s view on intelligence?
ability to process, manipulate and use information; a composite of core features, including reasoning, planning, problem solving, abstract thinking, comprehending ideas, learning quickly, and learning from experience
What is GOTTFREDSON’s view on intelligence?
ability to attend to, understand and adaptively respond to the external environment
What do individualistic cultures favour?
- Problem solving that leads to personal development + verbal and knowledge-based
- Tend to not value silence, rote learning and memorization
What do collectivist cultures favour?
- Problem solving that leads to greater social harmony PLUS
- Social intelligence, contemplative thinking, humility
- Rote learning, memorization, and silence
What is the difference between an IQ test and IQ?
- IQ test: psychometric tool to assess cognition
- IQ: score on a bunch of tests tapping into different cognitive processes
What are IQ test routinely used for?
Used to understand and diagnose cognitive challenges
- They are almost never used on their own
Who is Galton?
• Introduces the notion of heritability of intelligence
- First to note the importance of twin studies
- Introduced psychophysical test of measurement
Who is Cattell?
- Fan of experimental psychology
- Hypothesis: measuring the brain’s ability or efficiency should reflect intellectual ability
- Cattell’s test did not correlate well with grades
Who coined the term mental age?
Binet and Simon
Who was first to propose IQ?
Stern
Who is Goddard
Evil man
- Claimed that 80% of arriving immigrants were feeble-minded
- Renowned for having coined the term “moron”
- Suggested reproduction and immigration control
- Believed that mating and marriage with a feeble-minded person should not be allowed
Who is Terman?
- Major work improving the American version of IQ tests – added many new items
- This Stanford-Binet IQ test became the standard against which IQ tests of all sorts were to be compared
Who is Yerkes?
Developed group testing for WW1
- Develops versions for literate (alpha) and less literate (beta)
Who is Weschler?
Created the WAIS and WISC
What scales were in the WAIS when Weschler first created it?
There was only the performance scale and verbal scale
- Performance: doing stuff (not as culturally biased and verbal)
What are the conditions of administering the WAIS?
- Administered at least 2 years apart
- Evaluate the person in their preferred (native) language
- Should know when they learned the language
- Usually, you start with easier items
- Focus on effort rather than performance
What are the 4 scales of the WAIS?
- verbal comprehension
- perceptual reasoning
- working memory
- processing speed
What are the subtests of the verbal comprehension index?
similarities, vocabulary, information, and comprehension (optional)
What does the verbal comprehension index measure?
One’s ability to comprehend verbal stimuli, reason with semantic material and communicate thoughts and ideas with words
What are the subtests of the perceptual reasoning index?
bloc design, matrix reasoning, visual puzzles, figure weights (optional), and picture completion (optional
What does the perceptual reasoning index measure?
Fluid reasoning as well as perceptual organizational skills and visuo-construction
What are the subtests of the working memory index?
digit span, arithmetic, and letter-number sequencing (optional)
What does the working memory index measure?
attention, concentration, and working memory
What are Raven’s matrices?
Puzzle-like test, visual, less dependent on literacy and societal experience
- correlates highly with general IQ
What is the measure of dispersion on the WAIS?
- Mean = 100
* SD = 15
What is validity?
the extent to which you are measuring the things you intend to measure
- the overlap between actual intelligence and IQ scores
What is reliability?
the extent to which you can get the same results every time you test, at different times and with different people
What is the Flynn effect?
The idea that IQ gradually rises with each subsequent age group
What is crystallized knowledge?
the depth of a person’s acquired knowledge of a culture and the effective application of knowledge
Over time, what will decline?
raw scores and speed of processing
What are psychometric theories?
• Theories that derive from studying individual differences in test performance on cognitive tests (IQ tests)
- Premise: “Intelligence is what an IQ test measures”
What are limitations to psychometric theories?
- depend crucially on the sampling of tests used
- intertwined with the selected mathematical techniques used to analyze correlational data
What are the main psychometric theories?
Spearman’s g, Thurstone primary abilities and CHC model
What is Spearman’s two-factor theory?
Performance is determined by two factors:
- g, or general intelligence – it is genetic, inborn, and stable
- s, a specific ability related to the task at hand
What is g loading of a test?
The degree to which g is responsible for test performance
What is the lay view of intelligence?
General intelligence (g) is something people are born with - Because it is innate, it is relatively immune to remediation or improvement
What is Thurstone’s primary mental abilities theory?
the mind was dominated by several group factors: factors responsible for certain aspects of mental activity
- 7 to 9 factors were identified
What were Thurstone’s primary mental abilities?
V – verbal N – number S – spatial M – memory R – reasoning W – word fluency P – perceptual speed
Which analysis did Thurstone use for his primary mental abilities?
Confirmatory factor analysis
- Factor analysis’ role: reveal the independent factors then, knowing these factors, we can develop tests assessing them
Why was there a heated debate between Spearman and Thurstone?
Spearman: claimed group factors did not exist
Thurstone: claimed g did not exist
What is the structure of Vernon’s hierarchical model?
- A general factor g
- A verbal education (v:ed)
- A perceptual/mechanical/spatial (k:m)
What was Cattell’s view on intelligence? (CHC theory)
tended to view intelligence as being highly shaped by the environment, rather than genetic factors
What is the difference between crystallized and fluid intelligence?
crystallized intelligence: prior learning and experiences
fluid intelligence: independent of experience and education
Explain Cattell’s notion of deterioration of intelligence (CHC theory)
deterioration in intelligence in adults was not uniform across all tests
- higher g-saturated tests: showed the least decline across the life span
- g-unsaturated tests: showed the largest declines
What is Cattell’s investment theory?
People invest their fluid intelligence (Gf) to acquire specific skill, strategies, and knowledge in all kinds of fields (Gc)
What did Horn add to the CHC model?
- General visualization (Gv)
- General speediness (Gs)
How did Horn describe spatial intelligence?
- visualization (Vz)
- spatial orientation (S)
- flexibility closure (Cf)
- speed closure (Cs)
- adaptive flexibility (DFT)
How can flexibility closure and speed closure be defined?
keeping configurations in mind and finding the Gestalt among disparate parts in a visual field
According to Horn, what is general speediness (Gs)?
- speed copying (Sc)
- writing flexibility (Wf)
- perceptual speed (P)
What does Horn think Gs is measured most purely in?
In simple writing and checking tasks
What were Horn’s views on Gs?
Thought Gs was the by-product of how difficult the test is to a person rather than a stable trait
- Someone’s speed will vary in difference tasks
What were Horn’s views on g?
Rejects the notion that there existed a general intelligence, whether comprised of a single g or two g’s
Explain Carroll’s 3-stratum model
- stratum 3: g
- stratum 2: 8 broad abilities
- stratum 1: 65 narrow abilities
used EXPLORATORY techniques
What is the difference between the Cattell-Horn model and Carroll’s 3-stratum model?
The Cattell-Horn model used Ga for auditory processing, whereas Carroll used the designation Gu
What is Gs?
cognitive speediness
What is Gt?
processing speed
