New project to launch August 1

Dr. Laura Hahn (PI) and Dr. Pamela Hadley (Co-I) have teamed up to study the contribution of child and maternal gestures and responsive maternal language input to word learning opportunities, production practice, and spoken language vocabulary growth for toddlers with fragile X syndrome. Read the story here.
