neurological perspective
evolutionary perspective
concordance rate
degree to which one characteristic that occurs in one twin similarly occurs in the second twin
heredity

what is the ARAS responsible for
regulating arousal in the brain
what personality trait is the ARAS linked with
introversion and extraversion

states differences in personality are adaptive responses for survival and reproducitve success
conscientiousness
