Intelligence Flashcards
Intelligence
The ability to learn, think logically about abstract concepts, and adapt to
the environment
Origin of Intelligence theory and measurement
- Alfred Binet (1904)
- Mental Age: level of mental development compared to other
- William Stern (1912)
- Intelligence Quotient: MA/CA x 100=IQ
- Stanford-Binet Intelligence Tests
- Approximate normal distribution
Spearman’s Two-Factor
Theory of Intelligence
General Intelligence (g): broad thinking ability; “mental power” that underlies all intellectual tasks; neurologically based Specific Intelligence (s): abilities in particular areas (verbal, nonverbal, etc); learned/honed
Cattell and Horn’s two factor theory
- Fluid Ability: biologically based ability to think, to reason - Crystallized Ability: acquired knowledge and skills
Sternberg’s Triarchic Theory
Three interrelated subtheories used to explain how mental processes,
situations, and experience relate to intelligence
• Componential: analytical intelligence
• Experiential: creative intelligence
• Contextual: practical intelligence
analytical (g)
- Ability to
- think abstractly
- Process information
- Analyze, evaluate, judge
creative
- Ability to
- formulate new ideas
- Combine seemingly unrelated information
- Create, design, event
practical
Ability to •Adapt to environment •Shape environment to maximize effectiveness (strengths and weaknesses) •Use, apply, implement
Gardner’s Theory of Multiple Intelligences
• “an intelligence is a biopsychological potential to process information that can be
activated in a cultural setting to solve problems or create products that are of
value in culture.”
• Contends that there is no “g” factor
• Overall level of functioning is determined by interaction of strengths and weaknesses
(intelligences) with cultural setting
• 7-9 intelligences, which may or may not be fully realized based on environmental influences
Criticisms of Gardner & MI theories
Redundant (Lacks parsimony)
Vague
Lacks executive processor
Doesn’t hold up to statistical analysis (factor analysis)
Creativity
• Original thinking and problem-solving that produces a product valued by
society
• Ability to do things in new or different ways
• Divergent (vs. Convergent)
• Brainstorming, free writing, etc.
• Thinking outside the box
Divergent thinking
- Higher scores on word fluency and reading tests
- Associated with Extroversion and Openness (5 Factor Model)
- Loose memory networks
- Right brain (especially temporal lobe)
- Alcohol, humor, and sleep all increase creativity
- Greater WMC decreases creativity
Nature or nurture: The scientific data
• Higher order thinking- structural & functional neural networks:
frontal, parietal, temp lobes and cerebellum
• Correlations:
• Brain size
• Processing speed
• Brain efficiency hypothesis (related to glucose metabolism rates)
• Heritability: .75 (strong)
• Enriched environments produce changes in IQ
• Most notable in impoverished environments
• Average IQ is increasing over time
• Evidence of critical periods of development dependent upon stimulation
Assessment of Intelligence
- Intelligence Quotient (IQ)
- Originally (mental age /chronological age) x 100; average IQ is 100
- Intelligence tests:
- Binet-Simon scale (1905)
- Stanford-Binet Intelligence Scale 1916-)
- Now in 5th Edition
- The Wechsler Scales
The Wechsler Scales
- WAIS-IV: Wechsler Adult Intelligence Scale (4th edition)
- Age 16 and up
- WISC-IV: Wechsler Intelligence Scale for Children (4th edition)
- Age 6 to 16
- WPPSI-IV: Wechsler Preschool and Primary Scale of Intelligence
- Age 2.5 to 7
