Dr. Laura-Ann Petitto, Developmental Cognitive Neuroscientist, was interviewed on CNN’s Vital Signs (host, Dr. Sanjay Gupta) based on her three decades of research and discoveries about language learning in the human brain, the bilingual brain, the reading brain, and for her discoveries about the acquisition and neural organization of American Sign Language. This episode focused on the sense of hearing and how it relates to language learning, and Dr. Petitto provided scientific insights on the acquisition of signed language in deaf and hearing children and the role of visual sign phonology in supporting reading acquisition in deaf children.
