Study Notes
Intelligence Defined
- David Wechsler defined intelligence as the overall capacity to think rationally, act purposefully, and effectively interact with the environment.
Development of Intelligence Tests
- Alfred Binet, with Theodore Simon, developed procedures to identify students needing extra support.
- They created tests measuring various mental skills, focusing on fundamental abilities like memory, attention, and recognizing similarities/differences.
Mental Age
- Binet's work introduced the concept of mental age, which differs from a child's chronological age.
- Mental age is a measure of intelligence, expressing an individual's mental level based on the average abilities of their age group.
Stanford-Binet Intelligence Scale
- Lewis Terman adapted Binet's test, naming it the Stanford-Binet intelligence scale.
- Scores are expressed as an Intelligence Quotient (IQ).
Intelligence Quotient (IQ)
- IQ is a measure of overall intelligence, calculated by comparing an individual's score to the average score of others in the same group.
High IQ and Success
- Lewis Terman's longitudinal study of children with high IQs (above 140) showed they tended to be well-adjusted socially.
- These children also exhibited taller, stronger, and healthier features than average children.
- However, high intelligence doesn't guarantee success; other factors play a role in life achievements beyond school success.
Wechsler's Perspective
- David Wechsler (1896-1981) believed intelligence involved many mental skills.
- He also thought IQ scores could be affected by personality, motivation, and cultural variables.
- He developed the Wechsler Intelligence Scale for adults.
Wechsler Intelligence Scale
- Intended specifically for adults, rather than children.
- Includes 11 subtests covering various abilities.
- Subtest scores are gathered to create an overall verbal score, and performance score.
Wechsler Verbal Skills
- Vocabulary
- Comprehension
- Knowledge of general information
- Other verbal tasks
Wechsler Performance Skills
- Identifying missing components in incomplete pictures.
- Arranging pictures to tell stories.
- Arranging blocks to follow given patterns.
Wechsler Intelligence Scale for Children
- The Wechsler Intelligence Scale for Children (WISC-III) designed in 1991 measures intelligence in children from 6 to 16 years.
- The WISC-IV is the revised version of 2003.
Intelligence Test Principles
- Three essential elements of reliable tests:
- Standardization : The test is given to a large, representative sample of people under uniform conditions to generate norms against which individual scores are interpreted. IQ test norms follow a normal curve or normal distribution.
- Reliability: The ability of a test to give consistent results under the same conditions when administered repeatedly.
- Validity: The ability of a test to measure what it is intended to measure.
The Normal Curve (Normal Distribution)
- The bell-shaped normal distribution illustrates how most scores cluster around average in a typical population.
- IQ scores generally follow a normal curve, indicating similar clusters among the scores in a population.
Nature of Intelligence
- Psychologists disagree on the essential nature of intelligence, including whether it's a single, general ability or if it incorporates talents, skills, and mental aptitude.
Theories of Intelligence
- Charles Spearman: Proposed "general intelligence" (g factor) underpinning overall mental ability.
- Louis Thurstone: Believed intelligence comprises several distinct, independent "primary mental abilities".
- Howard Gardner: Argued for "multiple intelligences", each relevant within different cultural settings.
- Robert Sternberg: Described analytic, creative, and practical intelligence.
Roles of Genetics and Environment
- Both genetics and the environment influence intelligence.
- Twin studies demonstrate a strong genetic influence, suggesting identical twins raised together have highly correlated IQ scores, and those raised apart have slightly less similar IQs.
