These two videos show movements. I will describe how to take the movements and use them to communicate.
To
communicate you need two movements.The movement that is easier for the
person to perform will be the "No" response. If it is blinking, one
blink should be no. The reason for this is because a false "No" is
better than a false "Yes." (Don't change mid-way. This is just
confusing. Stick to what you are doing but be extra careful with
"Yes"es.)
First
you will teach the "No." In the above videos, the hand appears to move
easier. This will be the "No." Ask obvious "No" questions. ("Is your
name [obvious wrong name]?") Let the person know she can tell you "No"
by moving her hand. Keep asking "Is your name [wrong name]." You want that
movement strong and true.
Once
you are satisfied with the "No" movement response, you can move on to
yes. In the midst of your "No" questions, throw in a "Yes." ("Is your
name [correct name]?" after a few wrong name questions.) Instruct her to use
the foot to tell you "yes."
You
now have an interactive game you can play, an "Is your name..." game.
This game can be expanded into everyday life. For example, "Change the
channel?" I used this in the hospital with another "vegetable". I could
change the channel on her TV. (I know...we are told vegetables don't
communicate. I don't think it was known how to do it.)
Don't
be discouraged if "No" takes a long time. How long did it take to get
the movement? Hopefully "No" won't be as long, but be prepared in case.
