PSYS 001 Lecture Notes - Lecture 6: Intelligence Quotient, Fluid And Crystallized Intelligence, Standard Deviation
Document Summary
Intelligence: a mental ability consisting of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations. Specific intelligence (s): a measure of specific skills in narrow domains. Fluid intelligence: the capacity to learn new ways of solving problems or preforming activities. Crystallized intelligence: accumulated knowledge of the world we acquire throughout life. Standardization: given to large number of people at different ages and finding the average score at each age level. Flynn effect: observation that score on intelligence tests worldwide have creases over the past decades. Intelligence quotient (iq): intelligence based on age. Reliability: when a person is assed at different times the person will score about the same each time (95% or higher). Validity: how much the test actually measures the construct. Personnel selection: use of tests to select people who will potentially do well in certain areas. Normal distribution (bell curve): a pattern of scores. Frequency distribution: how frequently each score occurs.
