Document Summary
* personality: people"s typical ways of thinking, feeling and behaving. * traits: enduring predispositions that influence our behavior across many situations. * twins reared together: because correlations were extremely below 1. 0 even in identical twins with identical dna, non-shared environmental factors must play a large role in personality more so than genetics. * adoption studies: showed higher correlation between children and biological parents that adoptive parents even though the biological parents had not shared the environment with the child; shared environment plays little role. * not enough proof about personality traits in birth order, but frank sulloway found a correlation between later borns being more likely to favor revolutionary ideas (ex. evolution), and even higher correlation for extremely radical ideals. * molecular gene studies are used to try to pinpoint which genes are associated with specific personality traits, and work by examining a linkage between genes and known genetic markers but there are not many consistently replicated associations.
