A study involving Korean adoptees was designed to obtain information on how family involvement in culturally related activities factored into a child's ethnic identity. Results showed that children exposed to higher levels of involvement in Korean cultural activities attributed to a higher measure of Korean identity. In addition, these children were more easily able to communicate openly about their adoption. Children are able to express the adoption that they experienced. The implications of this study suggested that involvement of cultural activities of the child's native culture may help in the child's development of integrated ethnic identities. Another study, conceptually similarly, looked at both the parents and the children to measure how color-blind racial attitudes would affect engagement in activities of the adoptees native culture. Color blindness is the sociological concept that race, or racial characteristics, do not exist amongst people. The study found that parents scoring lower on color-blind racial attitudes positively correlated with high scores on acculturation and socialization levels, meaning parents that were aware of their cultural differences took part in more cultural activities of their adoptee. It is important to note that this study looked at international adoptions, which subsequently includes transracial adoptees, but is not specifically focused on this particular subset of individuals.
