Greetings all, I do hope than you and your families are all well.
A major problem with all AAC strategies (apart from deaf sign) is that compared to speech they are very slow. They all require a lot more effort on the part of the communicators, and a lot more patience and concentration from their listeners, than spoken conversation.
In a video-presentation to ISAAC in 1994, Stephen Hawking lamented that he could only generate 15 words a minute. Ordinary speakers can say up to 150 words a minute. Even now, an AAC user is doing well to generate 30 words a minute.
The comparative slowness of AAC leads some users and/or listeners to give up on it altogether, and others to use inappropriate strategies to speed up communication. An obvious example is leaping in to finish someone's sentence before you really know what they wanted to say.
Any partner-assisted communication strategies, including PECS, PODD books, E-Tran boards and FCT, are especially vulnerable to partner impatience leading to partners taking more control, or losing the message.
Recently I was stunned to see a video of a long-standing client, who usually holds onto a rod while he's typing so his partners can slow him down, 'typing' quickly with a new partner pressing letters by holding his right index finger while he looked around the room.
Fortunately nothing of great importance was being typed in the video, but the client had also had 2 tele-health consultations with his long-term psychologist involving the same partner. The psychologist was concerned about reliability because of the increase in speed and length of his communication, as well as changes of style and vocabulary.
The new partner made no attempt to check any of the output using the client's independent yes/no at any time. Ironically, some of the client's team were planning to use the video to train new staff!
When I asked the client why he'd allowed this to go on, he typed "I like her so I just let her do what she likes." Aargh!
A long post, but this is an important issue. We need to find ways for everyday communication - breakfast choices, or basic greetings - to be as quick and easy as possible, and use appropriate rate acceleration strategies with typing or spelling. And any partner-assisted output should be checked with Yes/No responses.
