Part of a series of booklets for parents of deaf-blind children prepared by Project STEPS (Steps Toward Effective Production of Speech), this booklet contains a list of words and their meanings and is designed to promote understanding about hearing and vision loss. The roles of professionals working with deaf blind children are explained. The range of programs and services for this population--from early intervention through sheltered workshops--is briefly considered. Medical treatments, such as irrigation of the ear and cataract surgery, are noted. Information is offered on hearing aids and vision aids. A section on training and teaching covers Public Law 94-142 (the Education For All Handicapped Children Act), approaches to changing behavior, sense training, communication, and special sources of help, such as occupational and physical therapy, mobility training and orientation. A glossary presents approximately 150 definitions of frequently used terms. Throughout the text, terms for which definitions are provided are indicated by boldface or italic print. (CL)
