Intelligence Concepts and Theories

Intelligence Concepts

• Intelligence is the ability to learn from experience, solve problems, and adapt using knowledge.
• Factor analysis is a statistical method identifying clusters of related items on tests, revealing underlying dimensions of performance.
• Charles Spearman linked factor analysis to general intelligence (g factor), a universal mental ability.
• L.L. Thurstone conducted extensive testing, finding seven clusters of primary mental abilities (also using factor analysis).
• Howard Gardner proposed multiple intelligences, suggesting different types of intelligence exist.
• Robert Sternberg identified three main intelligences: analytical, creative, and practical.

Intelligence Theories

• Cattell-Horn-Carroll (CHC) Theory bridges fluid and crystallized intelligence.
  • Crystallized intelligence is accumulated knowledge and verbal skills, increasing with age.
  • Fluid intelligence is the ability to reason quickly and abstractly, decreasing in late adulthood.
• Savant Syndrome: A condition where seemingly limited mental ability coexists with exceptional skill (e.g., computation, drawing).

Types of Intelligence

• Analytical intelligence involves solving well-defined problems with single correct answers.
• Creative intelligence involves adapting to novel situations and generating ideas.
• Practical intelligence addresses everyday, ill-defined tasks with multiple solutions.
• Emotional intelligence involves perceiving, understanding, managing, and using emotions.

Assessing Intelligence

• Intelligence tests assess mental aptitude, comparing individuals' performance with others using numerical scores.
• Aptitude tests predict future performance, learning capacity.
• Achievement tests reflect acquired knowledge.
• Francis Galton explored hereditary genius, proposing measures like reaction time and sensory acuity as indicators of intelligence.
• Alfred Binet developed questions to determine a child's mental age.
• Lewis Terman adapted Binet's test for American children, creating the Stanford-Binet.
• William Stern introduced the intelligence quotient (IQ): Mental Age / Chronological Age x 100 (initially for children).
• David Wechsler developed the Wechsler Adult Intelligence Scale (WAIS) and Wechsler Intelligence Scale for Children (WISC), widely used, and considered less biased than earlier tests.

Test Design Principles

• Standardizing involves testing procedures, using comparison groups to develop meaningful scores (normal curve).
• Reliability refers to a test's consistent results—split-half, test-retest, different forms.
• Validity refers to a test's accuracy in measuring what it intends to measure (content, predictive).

Intelligence and Development

• Longitudinal studies track the same individuals over time.
• Cross-sectional studies compare different age groups at one point in time.
• Flynn effect refers to observed increases in intelligence test scores over time and across cultures.

Related Conditions and Concepts

• Intellectual disability is a condition of limited mental ability.
• Stereotype threat refers to self-confirming concerns about negative stereotypes impacting performance (e.g., African Americans, women).
• Carol Dweck highlights growth and fixed mindsets related to intelligence.

General Intelligence

• It is the overall ability to learn and solve problems
• It is measured through different tests such as the Stanford-Binet and WAIS
