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.
