12 What changes occur in children s sign and spoken language acquisition post implantation? Are the changes predictable? Across ages? Across children with secondary disabilities? How can these findings be used for programming?

13 There is not one unified deaf community perspective on cochlear implants Attitudes towards cochlear implants are changing Culturally deaf families are beginning to consider implantation for their young children

Cochlear Implant Candidacy Factors Influencing Performance The Decision-Making Process Considerations in the Implantation Process What About Insurance? Surgical Considerations Educational Settings The Deaf Community Perspective Communication Methodology Sign Language Use Fitting the Speech Processor Training the Ear to Listen Resources Available in Spanish

17 Cochlear Implants and Children: Considerations for Implantation and Educational Planning

18 National Training Workshops Spoken Language and Sign: Optimizing Learning for Children with Cochlear Implants

19 Spoken Language and Sign It does not have to be a competition!

20 For spoken language to develop: Opportunities must be available to develop listening and speaking skills There must be times when sign is not utilized Spoken language must be valued and utilized in the child s daily environment

21 We want children to be the most effective language users and communicators possible. In any way possible! As early as possible!

22

23 The path of learning to listen may vary for each child and And each child with an implant will vary in their ability to listen to learn

25 V Accesses communication visually via ASL/Signs or visual clarifiers VA Accesses most information visually via ASL/Signs or visual clarifiers; obtains some benefit from auditory information VA Equally accesses information via ASL/Signs or Spoken English Av Accesses most information through spoken English, sometimes needs support via signs or visual clarifiers A Accesses all information through Spoken English

29 As a transition to oral language As an ongoing clarifier of spoken English. Bilingual development of ASL and Spoken English

36 The demographics of children with cochlear implants varies widely Spoken language and sign language outcomes vary for each child with a cochlear implant Early use of sign language can support the acquisition of spoken language development Continued research is important to support and validate the use of sign language with implanted children

37 Thank you to: James Madison University and Gallaudet University s Cochlear Implant Education Center for funding the graduate students who worked on this project: English King, Kelly Clingempeel Skubicz, Christi Hess, and Kate Belzner The University of Virginia Cochlear Implant Center (Lori Bobsin) for referrals The families and children involved in our project.
