Our July meeting featured guest speaker Liz Mann, a speech language pathologist who has many years of experience working with communication devices and children with special needs. Liz shared her knowledge about how language develops and how this development impacts at what point a communication device might be beneficial for someone who is nonverbal. Liz has worked with and is familiar with low tech communication boards, PECS, Prentke Romich devices, Dynavox devices, Tobii devices, the iPad, and a variety of switches just to name a few.
She showed a diagram of the hierarchy of symbol set selection, which is used to determine at what stage a person is able to decode symbols– a necessary skill for using a communication device successfully. Having the cognitive ability and skills to understand symbols such as drawings, photographs or words will determine what kind of assistive communication system may be useful for someone.
Liz explained the hierarchy in this way: presymbolic communication (gestures, eye gaze, purposeful moving to object), object representation (actual object or miniature item), photographic representation (picture of object or action), picture/drawing representation (line drawing or stick figures), printed words (words representing objects, ideas and actions).
For example, a person who is at the object representation level will not have the skills to use a device with stick figures representing people, objects, and actions, but may be able to indicate wants and needs by walking to an object and picking it up or gesturing to that object. A person who is at the photographic representation stage may be able to utilize picture cards, but not more abstract line drawings or stick figures found in many communication systems. Adults who are at the printed word stage and who later lose the ability to speak due to a stroke or traumatic brain injury may be frustrated by picture symbols and wish to use a communication device featuring pictures with printed words or printed words alone.
The group discussed that many well-intentioned people can easily make the mistake purchasing a communication application for a mobile device that is too complex for a person who is nonverbal. In other words, using a complex communication app with symbols and abstract drawings for a child who is only at the object representation stage will be a frustrating experience for the child and caregivers.
Liz recommended working with a knowledgeable speech therapist to help support the communication and language development of a child. Obtaining an assistive technology evaluation can also be valuable for determining the appropriate device or communication system for someone. Assistive technology evaluations can be requested through school systems and in private clinics or assistive technology labs. Easter Seals Greater Houston is one place that offers comprehensive assistive technology evaluations and follow-up training.
