Chapter 9 - Intelligence Flashcards
Early intelligence definition
(Boeings definition)
Intelligence is whatever intelligence measures
-anything and everything is intelligence
Problem: everything is intelligence
Galton’s theory
Prominent scientist
-people with better senses = more intelligent
-research showed that different sensory capacities were weakly correlated to each other (vision is weakly correlated to hearing)
-so how could senses be correlated to intelligence if they are not correlated to each other
-disproved over time by researchers
Binet and Simons theory
-government asked to created the first intelligence test, to determine who is smart and who isn’t to give more education and schooling to those that need
Higher order processes
Reasoning, understanding and judgment
-reason abstractly
-learn to adapt
-acquire knowledge
-benefit from experience
Intelligence is related to
The ability to think in the abstract
Spearman
Interested in people who get one item correct, will get another item correct
-what is the relationship between the test questions
Spearman’s theory
Intelligence was general —> account for overall differences in intellect among people
-if I do well on one test question, i will do better on others —> overall/general
-believed people had more powerful brains than other people = more G
-controversial
-is culturally based
Spearman’s theory: specific skills
A specific type of intelligence based off on a job
-someone with a high G could still perform poorly on a S
Cattell and Horns model
Model of newly learned tasks
-crystallized : accumulated knowledge of the worlds acquired over time, lasting knowledge, related to openness and experiences —> specific skill set
-fluid intelligence: capacity to learn new ways of solving problems, declines with age
-fluid intelligence flows into crystallized intelligence over time
-supports idea of g and s
Gardeners multiple intelligences
-G doesn’t explain all intelligence factors, only one component
-came up with eight different types of intelligence
-different interpretations should have different types of intelligence
Linguistic verbal
Intelligence based on how well we speak and write
Visual spatial
Musical
Kinaesthetic
Manipulate bodies in physical activities
Interpersonal and intrapersonal
Inter- interact with others
Intra- insight about self
Naturalistic
Recognize and understand animals, plants
Logical mathematical
Sternbergs triarchic model
Analytical, practical and creative
-under represented in these tests
-three components of intelligence
-these three are not neccesarily independant of each other
Practical
Street smarts
Analytical
Book smarts
Creative
Creativity
Biological intelligence based
-brain volume is positively correlated to intelligence at a .4 level (low moderate correlation) to volume, density of the brain
-higher verbal skills correlated to intelligence
-third variable issue: culture, education
-speed of processing (higher = intelligence tests better due to banked time)
-working memory efficiency
-where in the brain there are more activation (prefrontal cortex, parietal lobe)
Family studies
particular trait present in all family that lives together
-trait runs through
Galton family studies
Found that relatives that are closely related to people who are known to be highly intelligent were also fairly intelligent
-is this environment or genetics
-concluded intelligence must be genetic (senses come from genetics)
-failed to consider: families share environment as well as genetics
Twin studies IQ
IQ correlates more strongly with identical twins = more genetic
-genetics is not the ONLY thing/that is causes things
-doesn’t help with environment
Adoption studies
People who are living in different environments
-closely resemble adopted parents or biological parents
Adoption studies IQ
Intelligence is most similar to biological parents, strong contribution from genetics
-environment still plays a role (children removed from deprives (little stimulation) to enriched show improvement in IQ scores
Enriched stimulation in children
Increase IQ test scores
-daycare facilities
Perception and intelligence
The way we perceive intelligence affects our intelligence
-mindset (growth or fixed)
Expectation effects
The idea of what we expect will influence
-creates intelligence
Randomly assigned a title of higher intelligence, and students labeled as “bloomers” progressively had higher scores (based off teachers knowledge and their expectation of those students)
Environment of learning: school
Schooling influences intelligence
-people who are educated have more neural connections
-difficult to determine although if it boosted intelligence, or just presented more opportunities
