Study Notes
Defining Intelligence
- No agreed-upon definition of intelligence
- Boring's definition: intelligence is what intelligence tests measure
- Key questions:
- Is intelligence one ability or multiple?
- Is intelligence exclusive to humans?
Early Theories of Intelligence
- Francis Galton (1890s):
- Believed intelligence stemmed from sensory abilities
- Tested 9,000 individuals, no strong link found between sensory abilities and intelligence
- Helen Keller (blind and deaf) is a counterexample - highly accomplished
Binet & Simon (1905)
- Developed first intelligence test
- Defined intelligence as higher mental processes and abstract thinking
- Intelligence test development marked beginning of IQ testing
- By 1921, experts identified key intelligence abilities:
- Abstract reasoning
- Adapting to new environments
- Acquiring knowledge
- Learning from experiences
General vs Specific Abilities
- Charles Spearman (1927):
- Proposed general intelligence (g): overall cognitive ability
- Specific intelligence (s): abilities specific to certain tasks
- Thurstone (1938):
- Argued against "g"
- Proposed primary mental abilities:
- Verbal comprehension
- Word fluency
- Numeric ability
- Spatial visualization
- Associative memory
- Perceptual speed
- Inductive reasoning
Fluid vs Crystallized Intelligence
- Cattell & Horn (1940s/1960s):
- Fluid intelligence: ability to solve novel problems, think abstractly
- Crystallized intelligence: accumulated knowledge, facts, and experiences
- Fluid intelligence transitions into crystallized intelligence over time
Multiple Intelligences
- Gardner (1983, 1999):
- Many ways to be intelligent, various intelligences are distinct and independent
- Examples: linguistic, spatial, musical, kinesthetic
- An "intelligence" is:
- Distinct ability, independent from others
- Likely an evolutionary advantage
- Some people may be exceptional in only this specific area
- Critiques:
- Are these truly "intelligences" or just talents?
- Independent nature of abilities is questionable
- Some categories lack clear falsifiability (proof)
Triarchic Model (Sternberg 1983, 1988)
- Three types of intelligence:
- Analytical intelligence ("book smarts"): logical reasoning, problem-solving
- Practical intelligence ("street smarts"): handling everyday tasks
- Creative intelligence: thinking of novel solutions
- Critique: Components may not be as independent as claimed, potentially linked to 'g'
Neurological Bases of Intelligence
- Intelligence linked to different brain regions:
- Frontal lobe: executive function, planning, impulse control
- Prefrontal cortex: thinking, planning, language; active during 'g' tasks
- Temporal lobe: auditory processing, memory
- Parietal lobe: spatial abilities
- Occipital lobe: visual-spatial processing
- Processing speed:
- Reaction time: faster reaction time often linked to intelligence
- Working memory: related to many intelligence measures
Summary of Intelligence Theories
- Intelligence likely involves a general factor ('g') with subtypes that cluster together
- Definitions of intelligence differ across cultures and are influenced by education
