Explain two research findings that support the claim that biological factors are influential in shaping personality.

Answer:

Responses may vary but should include some or all of the following information: Skeptics of early twin research claimed that environmental factors were influencing personality rather than genetics because twins participating in early studies shared the same environment. To address this concern, future twin studies incorporated research that included twins raised in unshared environments as a way of eliminating the environmental variable from the study. Responses may vary but should include some or all of the following information: One reason why researchers argue for the importance of biological influences on personality is because research has revealed that identical twins are more similar in having certain personality traits than fraternal twins. Research has also revealed that identical twins raised apart are more similar in personality than fraternal twins raised together.
