Intelligence Flashcards
What is the definition of intelligence?
A hypothetical mental ability that enables people to direct their thinking, adapt to their circumstances and learn from their experiences.
What is the theory of hereditary genius?
Francis Galton
Theory of Hereditary Genius (1869)
• Variation in ability within the population
• Variations are inherited
• Nature vs nurture
• First to use questionnaire assessments
Wha si the theory of typical intelligence of age?
Alfred Binet and Theordore Simon • Identified typical intelligence for age • Intelligence scale (1905, 1908, 1911) • Developed age norms • 'mental age'
This was done after France opened schools to all children, so many weren’t able to read or write etc, so Binet and Simon were asked to develop assessment tools to be able to assess a child’s intelligence without them having to read or write so that they could put the children into classes. Try and see what you would expect a child to be able to achieve at each age group. Also enabled them to identify children that might be struggling and might need extra help - a way of supporting children in education and also developing an efficient education system.
What is general intelligence?
Charles Spearman (1904) notion of underlying general intelligence (g)
• Two factor theory of intelligence
• Special factors/abilities (s)
Performance on all tests comprise of g + s
What is crystallised intelligence?
Raymond Catell (1971) • Crystallised intelligence (gs) - retain facts, develop experience and skills, a solid factual type of knowledge, eg vocabulary • Fluid intelligence (gf) - identify patterns, solve complex problems, see order in chaos
How did intelligence used to be explained?
Spearman used s factors to explain individual variability/variation. This was a very dominant theory and still is. It has developed over the years.
Catell supported the idea of an underlying level of g, and developed this further. He thought there were two types of intelligence - crystallised and fluid.
In 1960s cognitive intelligence started to be researched more widely - eg memory, perception, processing, problem solving. A shift in ways of assessing intelligence.
What is the theory of multiple intelligences?
Modern theorie - Howard Gardner (1993) Multiple intelligences - potentials rather than a general underlying intelligence 1. Linguistic 2. Musical 3. Logical/mathematical 4. Spatial 5. Bodily-kinesthetic 6. Intrapersonal 7. Interpersonal
No longer bound to these seven - there have been more forms of intelligence which have been added eg moral intelligence, environmental intelligence
….ski - social inteligence - look up
Peargy??? - developmental intelligence
We have a number of different potentials which give us access to different ways of thinking. The 7 given are distinctive and don’t necessarily have overlap.
Evidence provided for this is people who have brain damage are sometimes very impaired in some areas but completely fine in other eg maths vs language. Also in people who may be classified as retarded in one way but may have huge musical or artistic ability, or in individuals who have savant (?) syndrome but are hugely talented.
People withbodily/kinestheticintelligence are skilled at using theirbodyto convey feelings and ideas. They have good hand-eye coordination and are very aware of their bodies. Their fine and gross motor skills are more advanced than the average person’s.
The wordintrapersonalmeans “within the self”—so, “intrapersonal intelligence” is another term for self-awareness or introspection. People who have highintrapersonal intelligenceare aware of their emotions, motivations, beliefs, and goals.
Interpersonal intelligenceis the ability to understand and interact effectively with others. It involves effective verbal and nonverbal communication, the ability to note distinctions among others, sensitivity to the moods and temperaments of others, and the ability to entertainmultipleperspectives.
About intelligence tests
- Valid and reliable psychological tests
- Performance on intellectual tasks: correlates with performance on other tasks - is stable over time
- Consistency between tests infers an underlying level of general intelligence - g factor
Different tests using different components. Find that people that score well in one test, tend to do well in others too.
Some of the most reliable tests in psychology.
Intelligence grows with age, but at around age 11 you can get a good idea of how ones intelligence is likely to sit for the rest of life.
What is IQ?
Intelligence Quotent - Index of intelligence derived from scoring intelligence tests (Stern 1912)
Originally calculated as:
(mental age/chronological age)x100
In modern times, calculated used percentile rankings which are the converted to equivalent IQ scores and projected onto a normal distribution curve
IQ is a scoring system, rather than a particular measure. Less broad than intelligence as a whole.
Was originally calculated by taking m
What are intelligence (IQ) tests typically subdivided into?
Typically subdivided into:
- Performance tasks: ie picture completion (fill in missing part of picture), block design (recreate pattern with blocks without instructions), matrix reasoning (number sin a grid or symbols and have to say which one is missing to complete the pattern), object assembly (like flat pack furniture, without instructions) - Verbal tasks: ie verbal reasoning, comprehension, arithmetic, digit span (measure of memory), letter-number sequencing
About the bell shaped IQ curve…
95% of population lie wit +/- 2SDs of the mean (ie IQ 70 to 130)
68% (2/3) of the population have an IQ within 1SD of the mean. Average is considered to be within +/- 1SD of the mean (85-115)
What are the scores of intellectual ability?
Very superior: >130 Superior: 120-129 High average: 110-119 Average: 90-109 Low average: 80-89 Borderline: 70-79 ---------------------------------------- *learning disability: <70 * Mild: 55-70 Moderate: 40-54 Severe: 25-39 Profound: <25
About intellectual ability/disability
Often concerned with people who are in the borderline range, as access to services and support then people get this if have an IQ score of less than 70. Others very borderline may not be able to have these services.
Tests often carried out by educational psychologists as there is a lot riding on them.
Double edge sword - good because can get help needed, but also can be a stigma attached to having a learning disability.
Tests get less robust at the very top end and very bottom end. Those with IQ of 130+ are generally considered to be gifted.
What are some common IQ tests?
Wechsler scales Raven's progressive matrices Cattle's culture fair IQ tests National adult reading test (NART) Dementia rating scale Bayley scales of infant and toddler development
What are the Wechsler scales?
WAIS (those who cant sit through the whole thing, eg someone who is ill), WASI (adult), WISC (children between 6-10), WPPSI (preschool and primary 2.5-7) - sit in a room with an examiner and go through these tests, age dependent, use diff version depending on the age of the person, 11 types of tests, 6 verbal and 5 performance
What are Reaven’s progressive matrices?
non-verbal, series of progressively more difficult matrices looking for patterns and symbols, timed, can have many people doing it at onc
What are Cattle’s culture fair IQ tests?
Tries to account for different culture and reduces the confounding factors
What is the national adult reading test (NART)?
strong correlations between reading and intelligence, person given a list of words to read one at a time, tricky words, asked to read and pronounce those words correctly, useful as provides reliable estimate for peoples intelligence premorbidly, reading and pronouncing is one of the skills that stays longest with illness, can’t use if damage to language area of brain or in dyslexia
What is the dementia rating scale?
way of monitoring progress of people with confusion, and monitoring fluctuations in their IQ
What are the bayley scales of infant and toddler development?
in young children, basic tests, looking at developmental milestones, seeing how a child’s cognitive ability is developing
