Participate in a adoption study!

Unrelated Siblings Of The Same Age Reared Together Since Infancy (*SURPs)

Dr. Nancy Segal, Professor of Psychology at California State University, Fullerton,
is conducting a study of similarities and differences in behavior
in unrelated siblings of the same age.


Study includes pairs of siblings of any age; children, teenagers, and adults.
Pairs may include two adoptees, or one adoptee and one birth sibling.
The maximum age difference between siblings is 9 months.
Adopted siblings must have been placed in their homes by age 1 year.
Siblings attending school must be in the same grade, but not necessarily
      in the same class or in the same school.

Participation does not require a great deal of time.
Research is currently being conducted in the United States and Canada.
Siblings from any country are welcome to apply.
A written report on the results of your participation will be provided.
