In spite of important advances in our knowledge and understanding of children’s development and positive influences from family, schools, and the community, there remain substantial gaps between findings from research and the policies that affect children. In this session, Hirokazu Yoshikawa addresses the impact of culture and public policy on the development of young children of undocumented immigrant parents. Dr. Yoshikawa discusses how traditional research assessments of cultural beliefs and family processes do not capture the specific contexts of being undocumented and socially excluded. He presents details of several research projects that capture the challenges associated specifically with these contexts, and identifies new pathways for acknowledging the struggles faced by these children.
