The majority of young deaf children, especially those with non-signing parents, are reared in language-impoverished environments. This can cause their social and cognitive development to differ markedly from hearing children. The Psychological Development of Deaf Children details those potential differences, paying special attention to how the psychological development of deaf children is affected by their interpersonal communication with parents, peers, and teachers. This careful and balanced consideration of existing evidence and research provides a new psychological perspective on deaf children and deafness.
