Biological psychology: helps researchers understand behavior through the relationship between heredity (genetic factors) and the environment
Nature vs Nurture
- Nature = heredity/biological/genetic/disposition
- Nurture = environmental/external (family, school, community)
Research in Nature vs Nurture
- Twin studies: determines the role of nature (inherited), uses monozigotic twins
- Adoption studies: investigate the role of nurture (upbringing) when one of the twins is adopted
- Family studies: heritability of outcomes (e.g. diseases), conducted among siblings, parents, or children to assess genetic links; also how individuals change and interact within the family
