Key Concepts in Intelligence and Testing

Here is a study guide summarizing key concepts and vocabulary based on your uploaded slides on intelligence and testing:

---

Key Concepts

1. Intelligence Definition

- The ability to learn from experience, solve problems, and adapt to new situations.

- Intelligence is a concept, not a measurable physical trait.

2. Major Theories of Intelligence

- Charles Spearman: General intelligence (g), supported by factor analysis.

- Howard Gardner: Multiple intelligences (8 types), including linguistic, logical-mathematical, musical, spatial, etc.

- Robert Sternberg: Triarchic theory of intelligence (analytical, creative, practical).

- L.L. Thurstone: Seven primary mental abilities, emphasizing separate clusters of skills.

3. Key Figures

- Alfred Binet: Developed the first intelligence test to predict school performance (mental age concept).

- Lewis Terman: Revised Binet's test into the Stanford-Binet IQ test.

- Sir Francis Galton: Early attempts to measure intelligence; believed it was inherited.

4. Types of Tests

- Achievement Tests: Assess learned knowledge (e.g., AP exams).

- Aptitude Tests: Predict future performance (e.g., SAT, ACT).

- WAIS: Measures verbal and performance IQ.

5. Test Principles

- Standardization: Ensures uniform test administration and scoring.

- Reliability: Consistency of test results (e.g., test-retest, split-half methods).

- Validity: Whether the test measures/predicts what it claims (construct and predictive validity).

6. Intelligence Testing Extremes

- Low: Intellectual disability (IQ ≤ 70).

- High: Gifted (IQ ≥ 130).

7. Nature vs. Nurture

- Genetics: Intelligence has a heritability estimate of 50–80%.

- Environment: Enrichment can improve intelligence, especially in early childhood.

8. Additional Insights

- Flynn Effect: Rising IQ scores over generations.

- Emotional Intelligence (EQ): The ability to perceive, manage, and use emotions.

Vocabulary to Know

- General Intelligence (g): A single factor believed to underlie various specific abilities.

- Factor Analysis: A statistical method to identify related variables.

- Multiple Intelligences: A theory that intelligence is multi-dimensional, including non-academic abilities.

- Triarchic Theory: Intelligence as three components—analytical, creative, and practical.

- Mental Age: A measurement of intellectual development compared to age norms.

- Standardization: Uniformity in testing conditions.

- Reliability: The degree to which a test produces consistent results.

- Validity: The accuracy of a test in measuring or predicting what it is intended to.

- Savant Syndrome: Exceptional skill in a limited area despite general cognitive disabilities.

- Flynn Effect: The phenomenon of rising IQ scores over time.

- Bell Curve (Normal Curve): The standard distribution of scores in a population.
