Document Summary
People"s typical ways of think, feeling, and behaving. Traits- relatively enduring predispositions that influence our behavior across many situations. Traits account in part for consistencies in our behavior across time and situations. Nomothetic (unstressed personality by understanding all the laws that govern the behavior in all individuals) vs. idiographic approaches (understand personality by understanding the unique that govern behavior in individual) to studying personality. Behavior-genetic methods attempt to disentangle the effects of: genetic factors. Play big role: shared environmental factors- shared environmental experiences between individual in families that make individuals more alike. Plays less of a role: non-shared environmental factors-different experiences between people in our family that make us less alike. Use twin and adoption studies to do this. Remember, genes code for proteins not specific behaviors. Genes have indirect influence on traits, while the environment influences how these are displayed in our lives. Twin studies vs. molecular genetic studies (pinpoint which genes are related to what traits)
