Does it make a difference in language development to ID a baby as deaf? Researchers in the UK are looking into it. They are studying whether deaf teens have better language skills if doctors determine they were deaf as infants. The University of Southampton study is comparing a pilot screening program conducted in Southampton and London in the 1990s to how those kids are doing now as teenagers. They already found that the screening seemed to make a difference when the children were 8 years old, and they want to see if that still holds true now.
