Vocab for intelligence

Intelligence

Aptitude Test: Measures growth and what you've learned over time. Essential for predicting future performance in various tasks.

Reliability, Validity, and Standardization: All intelligence tests must adhere to these principles:

  • Reliability: Refers to the extent to which a test yields consistent results over time.

    • Test-retest reliability: Involves administering the same test to the same group at different points in time to check consistency.

    • Split-half reliability: Compares scores from two halves of the same test (e.g., even items versus odd items).

  • Validity: Indicates whether a test measures what it claims to measure.

    • Construct validity: Assesses whether the test behavior accurately reflects the theoretical construct.

    • Predictive validity: Evaluates how effectively a test predicts specific future behaviors or outcomes.

  • Standardization: Establishes uniform testing procedures and meaningful scores by comparing an individual's performance to a retested group.

Types of Intelligence:

  • S Intelligence: Refers to being exceptionally skilled in a specific category (like excelling in English while being average in other subjects).

  • g (General Intelligence): Based on Charles Spearman's factor analysis, suggesting that individuals who excel in one area tend to score well across various domains, indicating a well-rounded intelligence.

  • Intelligence Quotient (IQ): A numerical scale used to assess intelligence levels relative to the average performance of others.

Mental Age vs. Chronological Age:

  • Mental Age: Represents an individual's intellectual or cognitive abilities relative to their peers.

  • Chronological Age: The actual biological age of an individual.

  • IQ Calculation: IQ is calculated using the formula: (Mental Age / Chronological Age) x 100.

Stereotypes and Intelligence:

  • Stereotype Threat: The risk of confirming negative stereotypes related to one’s race or cultural group, which can lead to decreased performance on academic tests.

  • Stereotype Lift: Conversely, positive reinforcement regarding one's group capabilities can enhance performance.

The Flynn Effect: A worldwide phenomenon highlighting the observed increase in intelligence test performance over generations, named after researcher James Flynn.

Types of Tests:

  • Achievement Tests: Assess knowledge and skills acquired from specific courses or educational experiences.

  • Aptitude Tests: Designed to predict an individual’s ability to succeed in a specific area, commonly used in entrance examinations.

Mindset Types:

  • Fixed Mindset: The belief that intelligence is static and unchangeable.

  • Growth Mindset: The belief that intelligence and abilities can be developed through effort, learning, and persistence.

Intelligence Types:

  • Fluid Intelligence: Refers to the capacity to process information quickly and logically. Research shows it declines with age, as noted in cross-sectional studies.

  • Crystallized Intelligence: Consists of accumulated knowledge over time, which typically shows positive correlation with age, as noted in longitudinal studies.

  • Emotional Intelligence: Involves perceiving, managing, and using emotions effectively in oneself and others.

Historical Figures:

  • Francis Galton: Often referred to as the father of eugenics; posited that intelligence can be inherited, emphasizing the mating of intelligent individuals.

  • Howard Gardner: Proposed the Multiple Intelligences Theory, identifying eight distinct types of intelligence.

  • Robert Sternberg: Developed the Triarchic Theory of Intelligence, which includes analytical, creative, and practical aspects of intelligence.

  • Alfred Binet: Created the first IQ test focusing on mental age; later revised by Lewis Terman, becoming known as the Stanford-Binet Test.

  • Savant Syndrome: Refers to individuals who may score low on standard IQ tests but possess extraordinary skills in a specific area (e.g., musical, artistic, or mathematical ability).

Statistical Measures of IQ:

  • Approximately 86% of individuals score between 85-115 on IQ tests, with scores below 70 indicating intellectual disabilities and scores above 130 indicating giftedness.

  • Lewis Terman’s refinements of Binet’s test led to the establishment of widely used intelligence assessments today, including the Stanford-Binet Test.

Understanding these key elements of intelligence testing provides a comprehensive view of how intelligence is evaluated and the various factors that influence our understanding of cognitive abilities.
