8 - Intelligence Flashcards
Intelligence
-Ability to acquire knowledge
- to think and reason effectivley
- to deal adaptively with the environment
Psychometric approach tries to explain nature of intelligence by questioning
Mental competences
(So how many abilities are out there?)
Cognitive processes approach tries to explain the nature of intelligence by questioning
Mental processes
(The underlying mechanisms, (mental speed etc.))
Catell and horn explaining intelligence
Intelligence is split in 2
- Crystallised intelligence
- Fluid intelligence
Crystallised intelligence developed over lifespans and is
Knowledge throughout life time
Ability to apply previous acquired knowledge to current problems LTM
Fluid intelligence peaks in adulthood and is
Flexible intelligence and ability to deal with new tasks and quickness to adapt
For this you do not need personal experiences
Sternberg explaining intelligence
3 types of intelligence
- Analytical
- Creative
- Practical
Defines intelligence in a way that helps people to become successful in life
Analytical intelligence (Boeken slim)
Academic problem solving and computation
Creative intelligence
Imaginative and innovative problem solving
Practical intelligence (Levens slim)
Street smarts and common sense
Gardner explaining intelligence
There are multiple types of intelligence (8 in total)
Support evidence for garner
Prodigy and savant
Prodigy
Child who has an extraordinary in one ability while having normal developments
in other abilities
Savant
- Extraordinary thing
High ability in one domain, low in other (good at remembering everything, but bad at speaking)
IQ (intelligence quotient) is measured by
IQ score = mental age dived by chronological age x 100
Average is 100, constant readjusting
Validity (of intelligence test)
Does it measure what is it supposed to measure? Is it generalizable?
Reliabity (of intelligence test)
Are the measurements consistent over time (generally)
Wechsler Adult Intelligence scale tests intelligence based on 4 underlying mechanisms
- standardised IQ and norming
- Mental abilities across lifespan
- Testing wide range of mental abilities
- Validity and reliability
2 assumptions of Binet (forms basis of IQ)
1) mental abilities generally develop with age
2) mental competence is a characteristic of a person, which is consistent over time…
The Flynn effect is the strong evidence that
Environment has a powerful impact on intelligence
PEOPLE GET SMARTER OVER TIME
(it is environment and not genes, bc gene pool could not change rapidly enough to account for change of IQ in time)
Environmental factors that explain Flynn effect
- Better education
- Better nutritition
- Diseased reduces
studies of intelligence are almost always
correlational
Focusses on correlation among people rather than intelligence
Dependent variable
The outcome
Independent variable
What you vary
