My daughter recently had a baby who was born deaf. We are all trying to come to grips with this, but we are getting conflicting information. I have been reading everything that I can find about deaf children and a lot of it recommends using sign language. The audiologist we spoke to said that if we use sign language with her it will retard her ability to speak. Can you help?
This is one of the most common dilemmas facing parents (and grandparents) of deaf children – and perhaps the one for which they are most frequently given advice driven by philosophy rather than evidence. Simply put, there is no evidence that learning to sign interferes with learning to speak. In fact, the research points to early sign language either supporting spoken language or having no effect, while it generally leads to better social-emotional functioning and early academic achievement. That said, all of this is much more complex than such a simple answer implies. Let me suggest an excellent video on the topic available in English and Spanish (captioned in both). “Through Your Child’s Eyes” is objective and informative…and should answer many of your questions.
Importantly, though, there is no need for an “either/or” decision. Providing your granddaughter with access to and support for both sign language and spoken language offers more opportunities for learning. And, no, the two will not interfere with each other any more than two languages do for bilingual children around the world. In fact, hearing children raised in bilingual environments show cognitive advantages as early as seven months of age (even before they are using those languages), although parallel research has not been done with deaf children.
