“Learning about learning: Ella’s window into the developing mind.” The aim of our world-renowned research is to better understand infant and child development based on groups of children rather than on individuals. Our published work can also be helpful for clinicians, teachers, and parents who work with children, including children with disabilities to learn more about children’s early social and cognitive development. We aim to better understand the world of our society’s youngest members, and hope that in doing so we might be able to make their world a better place.
