What is the following an example of:  You are working with a nonverbal 3-year-old trying to get her to use single words to indicate the type of snack that she wants.  First you show her two pictures, one of goldfish and the other apples, and ask “What do you want to eat?’  When she doesn’t provide you with a verbal response, you touch her arm, point to the choices and ask again.  When she still does not provide a verbal response, you say, “Say apple.”
