How are twin studies and adoption studies used to learn about the influences of nature and nurture?
● Studies with identical twins help researchers consider the effects of different environments on the traits and behavior of genetically identical people.
● Studies with fraternal twins allow researchers to consider the effects of similar environments on genetically different people.
● Studies reveal that adopted children share more personality trait similarities with their biological parents than with their adoptive parents. Adopted children are more similar to their adoptive parents in belief systems and the development of behaviors important to functioning in society
