Intelligence Theories and Cultural Influences

Intelligence Theories

• Two main approaches to understanding intelligence:
  • Psychometric approach
  • Information processing approach

Psychometric Approach

• Also known as the structural approach.
• Views intelligence as an aggregate of abilities.
• Explains performance using a single index of cognitive abilities.
• Focuses on the structure of intelligence (what it is).
• Examples:
  • Unifactor theory
  • Two-factor theory
  • Theory of primary mental abilities
• Psychometric tests are subjective and influenced by factors like education, time of day, and focus.

Information Processing Approach

• Describes the cognitive processes used in reasoning and problem-solving.
• Focuses on how an intelligent person acts.
• Emphasizes the cognitive functions underlying intelligent behavior.
• Examples:
  • Theory of multiple intelligences
  • PASS model
  • Triarchic theory of intelligence

Spearman's Two-Factor Theory

• Proposed by Spearman (psychometric approach).
• Intelligence has two components:
  • General intelligence (g)
  • Specific ability (s)
• The 's' component is specific to certain aspects of intelligence, explaining performance differences across tasks.

Theory of Multiple Intelligences

• Proposed by Howard Gardner (information processing approach).
• People possess a range of intelligences, not just a single intellectual capacity.
• Eight intelligences (with a possible ninth):
  • Musical
  • Interpersonal
  • Spatial-visual
  • Linguistic
  • Bodily-kinesthetic
  • Logical-mathematical
  • Intra-personal
  • Naturalist
  • Existentialist (possible ninth)
• Individuals possess a range of abilities; they are likely to be strong in multiple areas.

Triarchic Theory of Intelligence

• Proposed by Robert Sternberg (information processing approach) in the 1980s.
• Defines intelligence as the ability to achieve success in life based on personal standards and sociocultural context.
• Success depends on capitalizing on strengths and compensating for weaknesses.
• Achieved through a balance of analytical, creative, and practical abilities.
• Categorizes intelligence into three aspects:
  • Componential (Analytical skills)
  • Experiential (Creativity)
  • Practical (Contextual skills)
• Sternberg's theory is a cognitive approach, not behavioristic.
• He argued that intelligence tests ignore creativity and other important characteristics.

Key Functions in Triarchic Theory

• Componential (Analytical):
  • Analyze
  • Critique
  • Judge
  • Compare/Contrast
  • Evaluate
  • Assess
• Experiential (Creative):
  • Create
  • Invent
  • Discover
  • Imagine if…
  • Suppose that
  • Predict
• Contextual (Practical):
  • Apply
  • Use
  • Put into practice
  • Implement
  • Employ
  • Render

Componential (Analytical) Intelligence

• Referred to as "book smart."
• Related to traditional definitions of IQ and academic achievement.
• Involves abstract thinking and evaluation skills.
• Good at problem-solving.
• Example: Emma scores high on standardized tests due to her ability to evaluate and analyze materials.

Experiential (Creative) Intelligence

• The ability to invent new ideas and solutions in new situations.
• Using existing knowledge and skills to deal with new problems.
• Two categories:
  • Novelty: Ability to deal with a problem for the first time.
  • Automation: Ability to automatically perform repeated tasks.
• Example: James Bond uses his knowledge and skills to deal with new problems.

Practical (Contextual) Intelligence

• Referred to as "street-smart."
• Ability to adapt to an environment or change it to suit personal needs.
• Common sense.
• Ability to cope with concrete situations.
• Example: Johnny prepares for a salesman's tactics when buying a motorbike by comparing prices and deciding against extras.

PASS Model of Intelligence

• PASS stands for Planning, Attention, Simultaneous and Successive cognitive processing.
• Identifies three operational units important for understanding mental functioning:
  • Attention
  • Simultaneous and Successive Processing
  • Planning

Arousal/Attention

• Helps in attending to stimuli.
• Enables information processing.
• Requires an optimal level of arousal.

Simultaneous and Successive Processing

• Simultaneous: Perceiving relationships and integrating them into a meaningful pattern.
• Successive: Remembering information serially.

Planning

• Activated after attention and processing.
• Involves thinking of possible courses of action, implementing them, and evaluating their effectiveness.

Intelligence Quotient (IQ)

• $IQ = Intelligence Quotient$
• Influenced by both genetic and environmental factors.
• Heritability can be as high as 80%.
• Children can have higher IQs than parents.
• May be increased by certain brain exercises/activities (more research needed).
• Generally peaks at age 20 and can decline with age.
• Better socioeconomic status and education may increase IQ.

Intellectual Giftedness and Intellectual Deficiency

• Normal intelligence: IQ scores in the range of 90-110.
• Intellectual disability: IQ below 70.
• Exceptional talents: IQ above 130.

Intelligence and Culture

• Cultural knowledge shapes intelligence by influencing institutions and practices.
• Cultural intelligence helps communication and connection across different backgrounds.
• Factors affecting intelligence in culture:
  • Climate
  • Importance of intelligence
  • Racial and ethnic characteristics
  • Stress of the environment
• Culture influences how we see the world, make decisions, approach problems, and solve them, even unconsciously.

Intelligence and Culture Summary

• Intelligence must be understood within its cultural context.
• Different cultures have different conceptions of intelligence.
• Asian and African cultures have broader views, emphasizing social, emotional, and wisdom aspects more than Western cultures.
• People's behavior is guided by implicit theories rather than solely by test scores.
• Conventional intelligence tests may not represent strengths of individuals across cultures.
• No culture-free test exists; tests should be culture-relevant.
• Skills needed for adapting to specific cultures are partially overlapping.
• Intelligence needs to be understood in its cultural contexts.
