On this edition of ST, we speak with Dr. Lawrence Aber, the Willner Family Professor of Psychology and Public Policy at the Steinhardt School of Culture, Education, and Human Development at New York University, where he is also a University Professor. Dr. Aber is an internationally respected expert on child development, poverty, psychology, and how all of these relate to social policy. Last night, he gave a free lecture at the OU-Tulsa Schusterman Learning Center entitled "Is There 'Normal Trauma?' -- Historical and International Perspectives on Violence and Child Development," and he stopped by our KWGS studios to speak on this topic before giving his talk. Dr. Aber's scholarship draws on some four decades of research in the U.S. and abroad on how violence affects children's development. He emphasizes the enormous variety in children's responses to different types of violence -- and he remains cautiously optimistic about how doctors, social workers, therapists, teachers, and other professionals worldwide are getting better (in terms of professional aid, clinical care, and the like) at identifying and treating trauma in children.
