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)
Expressive vs. Receptive Language Receptive- ability to understand language Expressive- ability to formulate and produce language
Purpose of Communication Choose, obtain or reject Regulate social interactions or express emotion Get attention Receive and convey ideas or information
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
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
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
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.”
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?
