Document Summary
Chapter 9: the inheritance of personality - behavioral genetics and evolutionary psychology. Behavioral genetics: personality trait: a pattern of behaviour that is generally consistent across situations. Genes matter: not all of personality comes from experience, some comes from genes. Insight into effects of the environment: concluded that the portion of the childhood environments that siblings do not share is more important. Several developmental outcomes, including juvenile delinquency, aggression, and even love styles have been found to be affected by the shared family environment: extraversion was the only trait that seemed to not be influences by shared environment. Shared family environment being unimportant for personality development was reached too quickly on basis of limited data: personality research can employ many kinds of data and they all should be used. Nature vs. nurture: heritability calculations do not solve the nature vs nurture puzzle.
