Question

Quizplus · Accepted Answer

Twin studies and adoption studies are both methods that researchers use to investigate the role of biological factors in the development of psychological disorders. Twin studies involve comparing the rates of a disorder between identical twins (who share all of their genes) and fraternal twins (who share only half of their genes). Adoption studies, on the other hand, involve comparing the rates of a disorder between children who were adopted and raised apart from their biological parents (but share genes with them) and those who were adopted and raised by their biological parents (but may not share the same environment). By comparing these groups, researchers can gain insight into how much of a role genetics and environment play in the development of various disorders.
