Document Summary
Thursday october 11th 2018 (part 2) chapter 6. Important to understand how genetic and environmental factors interact. Genotype-environment interaction: differential response of individuals with different genotypes to the same environments, ex. extraversion-introversion; individuals with different genotypes (extrovert vs introvert) respond differently to the same environment (noise in a room) Molecular genetics: goal to identify the specific genes associated with personality traits, association method: identify whether individuals with a particular gene have higher or lower scores on a particular trait than those without the gene. Physiology and personality: refers to the functioning of organ systems within the body, differences in physiology indicate difference in psychological functioning; sensitive nervous system leading to traits of introversion. A physiological approach to personality: rq: which environmental conditions (ex. loud parties) affect which personality traits (ex. introversion) to produce a particular physiological response (ex. overstimulation, increased. Hr), which then promotes the behavioral response (ex. avoidance: figure 7. 1 (theoretical bridge)
