Document Summary

In psychology, usually studied in terms of personality and intelligence. Chapter 13: individual differences: construct is invisible. Large samples needed: often limited to non-experimental methods, other sources of variation to consider for any variable related to individual differences, there are environmental factors that might be adding to the variability i. e. ses & intelligence tests. Personality and intelligence are to some extent heritable: personality: 0. 3-0. 5. Individual differences make little difference as far as inclusive fitness is concerned therefore are invisible to natural selection: variability = noise in the system. There is no single, globally optimal human nature. Psychological traits: personality, part of psychological makeup, consistent over time i. e. being quick to anger, often measured with self-report tests. Psychological states: no temporal or situational consistency, transient mood. From an evolutionary perspective, we might think of psersonality as a behavioral strategy; a tendency to respond in specific ways to particular circumstances.
