    1. Evidence-Based Language Supports for Children Using AAC: Increasing Expressive Communication Cathy Binger, Ph.D., CCC-SLP University of New Mexico

    3. BACKGROUND Risks to Development for Children who use AAC At risk in all aspects of development, including language (e.g., Lund, 2001). Contributing factors (Romski, Sevcik, & Adamson, 1997) intrinsic factors e.g., cognitive and motor speech impairments extrinsic factors e.g., lack of communication opportunities

    4. BACKGROUND Communication Characteristics of Children who use AAC These children often (e.g., Light, Collier, & Parnes, 1985): are passive communicators initiate few interactions respond infrequently produce a limited number of communicative functions use restricted linguistic forms

    5. BACKGROUND Communication Characteristics of Communication Partners Partners often (e.g., Light, Collier, & Parnes, 1985): Take the majority of conversational turns Provide few opportunities for communication Ask predominantly Yes/No questions Interrupt individuals using AAC Focus on the technology, instead of the individual

    6. Limited Communication

    7. BACKGROUND Language Intervention Techniques To Increase Early Expressive Communication Skills Aided AAC Modeling Expectant Delay Open-Ended Question Asking Increased Responsivity e.g., Binger (2004); Kent-Walsh (2003)

    8. BACKGROUND Using these techniques increases: Communicative Turntaking Communicative Functions Length of Utterances Semantic Diversity Syntactic Complexity e.g., Binger (2004); Kent-Walsh (2003)

    9. Increased Communication

    10. Aided AAC Modeling Purpose To provide functional models of effective AAC system use. Method The communication partner: Selects aided symbols while labeling the symbols orally if light tech AAC is used the speech synthesizer provides the label if a voice output system is used.

    11. Without Aided AAC Modeling

    12. With Aided AAC Modeling

    13. Expectant Delay Purpose To provide communication opportunities. Method The communication partner: Maintains eye contact while: Maintaining an expectant facial expression Providing increased conversational pause time (Light & Binger, 1998)

    14. Without Expectant Delay

    15. With Expectant Delay

    16. Asking Open-Ended Questions Purpose To prompt higher-content communicative turns (e.g., Basil, 1992; Bruno & Dribbon, 1998). Method Replace yes/no questions with open-ended questions

    17. Without Open-Ended Questions

    18. With Open-Ended Questions

    19. Increased Responsivity Purpose To reinforce communicative attempts & expand utterances. Method Provide appropriate and consistent responses to communicative intent of messages.

    20. Limited Responsivity

    21. Increased Responsivity

    22. Putting It All Together Can assemble the skills within an interaction strategy for specific activities. Storybook Reading Activities Classroom Activities Play Activities Activities of Daily Living Can teach communication partners to implement such strategies. Kent-Walsh & McNaughton (2005)

    23. Storybook Reading Context

    25. Storybook Example

    26. WRAP-UP Implementing these evidence-based skills results in: Communication Partners Become less dominating Provide increased opportunities & support for communication Individuals who use AAC increase Communicative Turntaking Communicative Functions Length of Utterances Semantic Diversity Syntactic Complexity * Children may begin using skills that they already possess or acquire more complex linguistic structures

    27. WRAP-UP Clinical Implications Instruction involves very little training time Instruction yields very positive changes in children Instruction yields high participant satisfaction
