PSY 324 Lecture Notes - Lecture 6: Fluid And Crystallized Intelligence, Intelligence Quotient, Factor Analysis
Document Summary
The field of psychometrics developed a method for measuring products of common abilities: intelligence: first developed by alfred binet and his colleague theodore simon in 1905. Intelligence: overall thinking and learning abilities, as measured by an intelligence test. Intelligence can be improved through education, mental and physical stimulation, exercise, and nutrition. Flynn effect: iq of the whole population increases about . 33 points each year: for this reason, old iq tests must be re-standardized. Also called the three-stratum theory of intelligence: stratum 1: narrow abilities, stratum 2: broad abilities, stratum 3: general ability. This is the most empirically supported theory of intelligence. General ability/general intelligence (g): a common intelligence that correlates with, and influences, all intellectual abilities: crystalized intelligence: intellectual skills that depend on accumulated knowledge. Influenced more by culture: fluid intelligence: ability to reason and process information. Made up of three separate but interacting intelligences: analytical: applying strategies, metacognition, self-regulation, creative: solving new tasks.
