Evaluation of adoption studies

Question 1

1 Strength base on ethics?

Answer 1

Usually very ethical because their is no direct manipulation of the twins. The adoption occurs naturally and the psychologist simply track and measure the behavior.

Question 2

1 strength based on ecological validity?

Answer 2

High in ecological validity as nothing is directly manipulated so it is not artificial in any way.
-The findings are naturally occurring and so could be generalized to other real situations

Question 3

1 Strength regarding data collection?

Answer 3

Collects both qualitative and quantitative date thereby increasing validity

Question 4

1 Weakness regarding adoption families?

Answer 4

Adoption agencies try to place children with families similar to their birth families meaning the change in nurture is not complete so the role of nature could be overestimated.

Question 5

1 weakness regarding sampling?

Answer 5

Suffers from sampling bias because adoption participants often answer advertisements (Volunteer sample) so they may only represent a certain type of people and are not truly representative and can not be generalized to all adoptive children.
