The acquisition of oral and written language in six deaf infants is compared from ages one and two years for periods of four and five years. The results indicate: (1) Acquisition of written language is not dependent on oral language; (2) Written language teaching can be initiated at about one year of age; and (3) Written language is easier to learn than oral language. These results suggest that written language instruction in early life helps deaf infants acquire language.

The auditory training course of a 3-year 5-month-old child with acquired deafness who received a Nucleus 22 channel implant is reported. Soon after switching it on, her response was not very clear.There was good subsequent progress in auditory discrimination, whereas the patient's major communication strategy preoperatively had been manual, lip-reading, and written language. Her vowel discrimination score reached 100% in 8 months.The patient's articulation and speech intonation has also improved, and her auditory reception of environmental sounds has also shown relative improvement.
