Defining Intelligence:
Psychologists define intelligence as the ability to learn from experience, solve problems, and adapt to new situations. This concept varies culturally
Spearman
Charles Spearman proposed the concept of general intelligence (g), suggesting that individuals who excel in one cognitive area tend to perform well across others.
Cattell-Horn-Carroll Theory
Raymond Cattell and John Horn introduced fluid intelligence (Gf), the ability to reason and solve novel problems, and crystallized intelligence (Gc), which involves accumulated knowledge. The Cattell-Horn-Carroll (CHC) theory supports both a general intelligence factor and specific abilities, bridging the two concepts.
Multiple Intelligences
Howard Gardner’s theory proposes eight (or nine) distinct intelligences, such as linguistic and logical-mathematical, suggesting that different individuals possess various strengths. Critics argue about the practical implications of this theory, particularly regarding learning styles.
Sternberg’s Triarchic Theory
Robert Sternberg emphasizes three intelligences: analytical (academic problem-solving), creative (innovation), and practical (everyday tasks). Both Gardner and Sternberg highlight the importance of diverse abilities in achieving success beyond traditional measures.
General Intelligence and Achievement
Despite the focus on multiple intelligences, general intelligence (g) remains a strong predictor of success, including income and academic achievement. Studies show a correlation between intelligence scores and later life outcomes, emphasizing the role of cognitive ability in various complex tasks.
Definition
Intelligence is the ability to learn from experience, solve problems, and adapt to new situations, varying significantly across cultures.
General Intelligence (g)
Proposed by Charles Spearman, it suggests a core cognitive ability that influences performance across various tasks.
Thurstone’s Critique
L. L. Thurstone identified seven distinct mental abilities, arguing against a single intelligence measure, yet evidence of g persists.
Cattell-Horn-Carroll Theory
This model distinguishes between fluid intelligence (Gf) and crystallized intelligence (Gc), bridging general and specific abilities.
Multiple Intelligences
Howard Gardner’s theory posits at least eight intelligences (e.g., linguistic, logical-mathematical), emphasizing diverse strengths, though its practical application faces scrutiny.
Sternberg’s Triarchic Theory
Robert Sternberg’s framework includes analytical, creative, and practical intelligence, underscoring that success involves more than academic skills.
Impact of general intelligence
General intelligence strongly predicts life outcomes, including academic success and income, highlighting its significance in various domains.
Intelligence Tests:
Intelligence Tests: These assess mental aptitudes and provide numerical scores to compare individuals’ abilities. Psychologists design these tests to ensure they measure cognitive abilities reliably and validly.
Achievement Tests
Achievement Tests: Reflect what a person has learned (e.g., final exams).
Aptitude Tests:
Aptitude Tests: Predict future learning capabilities (e.g., entrance exams). These tests often correlate strongly with intelligence test scores, indicating a relationship between general intelligence and learning ability.
Francis Galton:
Francis Galton: Initiated efforts to measure intelligence through physical and mental traits but found limited success. His work laid the groundwork for statistical methods in psychology.
Alfred Binet:
Alfred Binet: Developed the first practical intelligence test in early 20th-century France to help identify children needing educational support. He introduced the concept of “mental age” to measure a child’s intellectual development relative to age norms. Binet emphasized the potential for growth in intelligence rather than fixed capabilities.
Lewis Terman:
Lewis Terman: Adapted Binet’s work for the U.S., creating the Stanford-Binet test and introducing the IQ concept, which calculated intelligence as a ratio of mental age to chronological age. However, this formula had limitations for adults, leading to the development of more nuanced intelligence assessments.
Intelligence Tests
Intelligence Tests: Assess mental aptitudes and provide scores to compare individuals. They are designed to be reliable and valid measures of cognitive ability.
Types of Tests:
Achievement Tests: Measure what a person has learned (e.g., exams).
Aptitude Tests: Predict future learning potential (e.g., entrance exams) and correlate closely with intelligence test scores.
Historical Development: Francis Galton
Francis Galton: Attempted to measure intelligence through various traits but faced challenges. His work contributed to statistical methods in psychology.
Historical Development: Alfred Binet
Alfred Binet: Created the first practical intelligence test to identify children needing educational support. Introduced the concept of “mental age” to assess intellectual development.
Historical Development: Lewis Terman
Lewis Terman: Adapted Binet’s work to the U.S., creating the Stanford-Binet test and introducing the IQ concept, although the initial IQ formula had limitations for adults.
Evolution of Testing
Evolution of Testing: The focus has shifted from measuring fixed abilities to understanding and enhancing learning potential.
Heredity and Intelligence
Heritability refers to the proportion of variation in intelligence within a group attributed to genetics, estimated between 50% and 80%. However, heritability applies to groups, not individuals.
Twin and Adoption Studies:
Twin and Adoption Studies: Identical twins, regardless of being raised together or apart, show high correlations in intelligence scores (0.85 and 0.72, respectively), indicating a strong genetic influence. Fraternal twins (0.60) and siblings (0.45) exhibit lower correlations, emphasizing the role of shared genetics.
Brain Similarities
Brain Similarities: Neuroimaging reveals that identical twins have similar brain structures and activity related to intelligence.
Genetic Contribution
Genetic Contributions: While many genes are linked to intelligence, these account for only a small percentage of variations in educational achievement, highlighting the polygenic nature of intelligence.
Environmental Impact:
Environmental Impact: Shared environments can modestly affect intelligence. Studies show that children adopted from impoverished backgrounds into wealthier families typically see an increase in IQ scores.
Adoption Studies
Adoption Studies: Adopted children tend to resemble their biological parents’ intelligence scores more over time, suggesting that genetic factors become more pronounced as they age.
Experience Accumulation
Experience Accumulation: As individuals gain life experience, genetic influences on intelligence also appear to strengthen, with heritability increasing from childhood into adulthood.
What Is Personality?
Personality refers to our characteristic patterns of thinking, feeling, and behaving. Various theories contribute to our understanding of personality
Psychoanalytic Theory (Freud):
Focuses on childhood experiences and unconscious motivations.
Humanistic Theories:
Emphasize inner growth and self-fulfillment
Trait Theories
Analyze characteristic behavior patterns.
Social-Cognitive Theories
Examine the interplay between traits and social context.
