Learn the basics about Task Analysis in ABA

What is a Task Analysis?

In Applied Behavior Analysis (ABA), a Task Analysis is a process of breaking down complex tasks into smaller, more manageable steps. This technique is essential when teaching skills that involve multiple steps, as it helps both the RBT and the learner focus on one part of the task at a time. For example, brushing teeth can be broken down into steps such as picking up the toothbrush, applying toothpaste, brushing each section of the mouth, and rinsing.

Why Use a Task Analysis?

A Task Analysis is useful for teaching individuals with ASD (Autism Spectrum Disorder) or other developmental disabilities how to perform multi-step tasks independently. It allows for systematic teaching and assessment of each step, ensuring the learner masters one component before moving to the next.

Example of a Task Analysis

One common example of a Task Analysis is teaching handwashing:

1. Turn on the faucet.
2. Wet hands with water.
3. Apply soap to hands.
4. Rub hands together for 20 seconds.
5. Rinse soap off hands.
6. Turn off the faucet.
7. Dry hands with a towel.

By breaking down the steps, the RBT can teach one component at a time using chaining techniques.

What is Chaining?

Chaining is a teaching technique used alongside Task Analysis to link individual steps into a cohesive skill. In ABA, Chaining is the process of teaching complex behaviors by connecting smaller, taught behaviors. There are three primary types of chaining techniques:

1. Forward Chaining: Teaching the first step first and then sequentially adding the next steps once the previous one is mastered. For instance, when teaching handwashing, the learner might start by learning to turn on the faucet, and once mastered, proceed to wetting hands.
2. Backward Chaining: Teaching the last step first and moving backward through the sequence. This method helps the learner experience the final successful outcome early on, boosting motivation.
3. Total Task Chaining: Teaching all the steps at once rather than one at a time. This method is often used when the learner has some familiarity with the task.

Example of Forward Chaining

Imagine teaching a child to make a sandwich using Forward Chaining:

1. Teach the child to gather ingredients (bread, peanut butter, jelly).
2. Once mastered, add the next step—spreading peanut butter on one slice of bread.
3. Next, teach spreading jelly on the other slice.
4. Then, show how to put the slices together.
5. Finally, instruct cutting the sandwich into halves.

This step-by-step addition lets the learner build confidence and competence gradually.

How to Choose a Chaining Technique

The choice between Forward, Backward, and Total Task Chaining depends on the learner’s current skill level, preferences, and the complexity of the task. Forward Chaining works well for tasks with natural sequences, while Backward Chaining is beneficial when motivation is enhanced by completing the final step. Total task chaining is suitable for learners who can attempt the whole task with guidance.
