  1. Angie Sherman April 22, 2010 Alternative and Augmentative Communication(AAC)

  2. Augmentative vs. Alternative • Augmentative often refers to the supplementation of, or addition to, natural speech to enhance communication (combining speech and gesture) • Alternative refers to the substitution of another form of communication for natural speech (using signs, symbols, objects, devices) (Lloyd and Soto, 1993; Beukelman and Mirenda, 1998)

  3. Expressive vs. Receptive Language • Receptive- ability to understand language • Expressive- ability to formulate and produce language

  4. Purpose of Communication • Choose, obtain or reject • Regulate social interactions or express emotion • Get attention • Receive and convey ideas or information • http://aac.unl.edu/yaack/b0.html

  5. Forms of Communication • Facial Expression- eye contact, smile, frown etc. • Body Movements- bringing you to an object or an object to you, pushing away an object, throwing, aggression • Vocalization- grunting, laughing, crying, yelling, any kind of verbal sound not recognized as formal language • Conventional Gestures- pointing, waving, nodding • Words- what we understand as language • Manual Signs- similar to sign language but may be unique to child or environment • Picture or Object Symbols-used for symbolic representation of an item or action

  6. AAC Systems • Aided- requires tools or equipment; voice output devices, PEC exchange systems, paper and pencil • Unaided- requires only the users body; sign language, gestures and voice www.asha.org/public/speech/disorders/AAC

  7. Voice Output Devices • Many companies with similar products • Dynavox • Latest to market- iPhone, iTouch, iPad • Considerations • Cost; device and repair, availability of grants • Reliability, sturdiness, quality of output, battery • Portability • Ease of interaction

  8. How does this quote apply in a school setting? “There is evidence to suggest that people do not always recognize the communicative content of behavior that does not take a conventional communicative form, and thus they do not behave in an interactive manner.”

  9. What do you think? • Can students who can’t talk read? • What is multi-modal communication and why is it important? • Does using an automated device hinder vocalization? http://aac.unl.edu/yaack/b2.html
