Prompting is a critical part of the teaching process, particularly when introducing new and challenging skills. If no assistance is given, the learner would likely respond incorrectly over and over and eventually get very frustrated. Practicing these errors impedes learning.
For example, if you were given an address in an unfamiliar area and told to drive there, you would probably try a number of different routes without success and therefore never learn how to get to your destination.
It’s best practice to “fade” prompts (i.e. decrease the level of assistance) as soon as the learner can perform the skill on their own. If prompts are not faded at the appropriate time, the learner could start to use them as a “crutch” and have difficulty with independence. This is called prompt dependency.
For example, if you tell your child to brush his teeth every night he will start to rely on that prompt. If you are away for the night, it’s unlikely that your child will brush his teeth because he is so used to that reminder.
Another component of prompt fading is called “differential reinforcement.” This term refers to providing a lot of reinforcement for certain responses and not as much for others in an effort to shape behavior and increase independence.
For example, let’s say you are teaching your child to put her coat on by herself. To start, you help her put her arms in the right sleeves, find the zipper, and zip the coat. Because she completed the task, you say, “Great job putting on your coat.”.
The next time, she puts her arms in the right sleeves by herself and you help her find the zipper and zip the coat. You provide even more reinforcement because she’s starting to demonstrate independence. You say, “That’s so awesome! You put on your coat by yourself! I love it!” and give her a big hug.
This momentum continues. After some time, you tell your child to put on her coat, and she does it all by herself. You immediately pick her up and hug her, say how great it is that she put on her coat without any of your help, and you give her a lollipop because she did such a great job.
