This paper looked at data from a three-year study of preschool-aged deaf children in the United States to see how children’s early signing skills affected the rate of growth of their early literacy skills. It focused on children whose level of hearing was low enough to mean they had little or no access to spoken language, and who were growing up in homes where signs were regularly used for communication.
It examined the children’s skill levels in letter and word identification, and how quickly they improved over time. It also considered how much these were affected by the presence of deaf parents in the home and how skilled the children were in sign language.
