Characteristics Affecting Device Usage
Communicative Abilities How does the child currently communicate? Does the child engage in intentional
communication? How well does the child understand the
communication of others? (receptive communication)
![Page 7: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/7.jpg)
Motor Abilities What are the child’s current speech and
oral motor abilities? What movements does the child have
sufficient control over that can be used for AAC activation and control?
How does the child move from place to place?
Characteristics Affecting Device Usage
![Page 8: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/8.jpg)
Characteristics Affecting Device Usage
Cognitive abilities What cognitive abilities does the child
have? Does the child engage in intentional
communicative behavior? Does the child appear to understand the
concepts of causality, means-end and symbols? Does the child do better utilizing recognition
versus recall memory?
![Page 9: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/9.jpg)
Sensory Functioning Does the child have and vision difficulties? Does the child have any hearing
difficulties? Is the child overly sensitive to stimuli?

Voice output system-
Electronic systems used to replace speech for individuals with speech impairments
Allows individuals to actively participate in communication interaction
Produce electronic voice output through speech synthesis or natural speech
Often takes time to prepare responses

Types of Communication Devices
![Page 16: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/16.jpg)
PICTURE BASED
![Page 17: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/17.jpg)
Picture Based SystemThe use of pictures to facilitate communication
Child chooses a picture to make a request
System can range from no-tech to high-tech
![Page 18: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/18.jpg)
Picture Based System- PECS Picture Exchange
Communication (PECS) The individual gives a
picture of desired item to communicative partner who then honors the request
6 phases ( discrimination, sentences, answering questions, etc.)
![Page 19: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/19.jpg)
Affordable Effective for
multiple etiologies Allows for social
communication Can be used even
after “young child” years
Requires a lot of attention to learn
Communication limited to pictures available
PROS CONS
Picture Based System- PECS
![Page 20: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/20.jpg)
Picture Based System- M3
Dynavox M3
first speech-generating device to feature touchscreen technology
Prerecorded messages
Ideal for young children because no literacy skills are needed
![Page 21: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/21.jpg)
Messages sorted by situational context
Provides verbal feedback via digitized feedback
Visual AND auditory feedback
Multiple access methods
Mid-tech, so requires some training to use and program
Must be charged to work
Costly No room for error
correction
PROS CONS
Picture Based System- M3
![Page 22: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/22.jpg)
A wide array of clients would benefit from the use of Picture Based Systems
Low tech systems- ideal for any level of cognitive function, easier to use with high motor ability.
High tech systems- can be more suited for children with low motor abilities because of the multitude of access methods
Both require a higher attention span
Picture Based System

Three Dimensional ObjectA tangible, often large, object children can use to communicate
Has dimensions unlike a flat screen or flat pictures
Often a switch
![Page 25: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/25.jpg)

Ideal for communication for individuals that need a larger target area
Low tech, so easy to program and use
Can hook up to other devices
Only has one recorded phrase at a time
Costly Not very durable
PROS CONS
Three Dimensional Object- BIG mack
![Page 27: AAC for Very young Children](https://reader036.vdocument.in/reader036/viewer/2022062813/568164aa550346895dd6a8e8/html5/thumbnails/27.jpg)
A smaller clientele would benefit from using a BIGmack than Picture Based Devices
Provides a larger target for those with low motor ability or visual impairments
Allows those with low motor ability to play with toys or make requests
For those with low cognitive function, can be taught to use the BIGmack to make requests
