Total task presentation uses prompting, as necessary, to complete all of the steps in a chain on every trial. This has the advantage, like backward chaining, of completing the chain. This is really a prompt-fading procedure. As you guide/prompt a client through all steps, you gradually fade these prompts to allow the client to demonstrate the skill without them. Once the client has completed all steps without prompting, the task has been mastered. A good skill to train using total task training would be.
A. putting the final piece in a jigsaw puzzle to complete it
B. washing one's hair
C. crossing shoelaces before training shoe tying
D. putting soap in the dishwasher and turning it on

The correct answer is letter B. washing one's hair.

Explanation:

Total task chaining means that the entire sequence of steps in a task must be completed. The behavior is reinforced after the completion of the steps. Notice how options A, C, and D do not concern the whole task, but only parts of it. Letter C, for instance, refers to forward chaining, since it is focusing on the first step - crossing the shoelaces - instead of the whole process of tying shoes. The option that refers to a total task is letter B. Washing one's hair includes all the steps - wetting the hair, applying shampoo, rinsing, applying hair conditioner, rinsing again. Reinforcement comes after the whole sequence is finished.
