Any skill can be thought of as a chain of small steps. These small steps are identified by completing a Task Analysis. Each step, or link in the chain, serves as a cue to do the next step.
By building one step onto another learned step in the sequence, a strong chain can be created. She often cries and throws her bowl. You decide that it would be helpful to teach her to use a spoon to feed herself. A task analysis is completed and five steps in the spoon-feeding chain are identified.
As Simithy begins to learn the steps, each one prompts the next one. When she has the spoon in her hand it helps her to know that the next step is to put it in the bowl. The spoon in the bowl prompts her to scoop the food. The food on the spoon prompts her to lift the food, and holding a spoonful of food prompts her to put it in her mouth.
Of course the big pay off is the spoonful of her favourite food. This is where the child is rewarded for approximating or getting close to the steps that we want to see in the end. In shaping a skill, the child is rewarded when part of the skill is done well.
Initially, if Simithy touches the spoon you might reward her with praise. Gradually, that will not be good enough to receive praise, and praise will only be given when the step of picking up the spoon is done a little bit better.
The rule for giving reinforcement, changes as you expect more independence and greater accuracy. As mentioned earlier, there are two kinds of chaining — forwards and backwards. The difference between the two is the point at which you begin teaching the steps in the chain.
With forwards chaining, you would start by teaching Simithy to pick up the spoon.
With backwards chaining, you would begin by teaching her to put the food in her mouth. Both are perfectly good approaches in this case. How do you decide whether to use forwards or backwards chaining?
It is best to teach the sequence of steps from the beginning to the end forwards chaining when: The child understands the final end product. The child is somewhat motivated to learn the new skill e.
The child displays little resistance to following instruction and can tolerate possibly being prompted through several steps of the task analysis.
In some cases, it is best to use backwards chaining e. You might choose to use this when: The child does not understand the final end product e. Motivation to learn the new skill is initially low and the child needs to very quickly receive an effective reward for cooperation and completion of the step.
This will help to draw an association with the end product. Over time, as the child is required to complete more steps, she learns to tolerate delays in being rewarded.
The child shows resistance to instruction, prompting, etc. This will reduce future resistance, as the child understands that rewards are coming soon. What does it look like when you teach, using chaining and shaping?
Simithy is motivated to learn this new skill, understands what a spoonful of food in her mouth feels like, and is cooperative while being instructed.Chaining is an instructional procedure used in behavioral psychology, experimental analysis of behavior and applied behavior analysis. It involves reinforcing individual responses occurring in a sequence to form a complex behavior.

Applied Behavior Analysis (ABA) includes tools and strategies widely used in the autism community.Â This article is the second in a series of articles about strategies associated with applied behavior analysis. Applied Behavior Analysis: The Role of Task Analysis and Chaining A task analysis is developed using one of three methods.
Behavior modification refers to behavior-change procedures that were employed during the s and early s. Chaining; Some areas of Functional behavior assessment forms the core of applied behavior analysis.
Many techniques in this therapy are specific techniques aimed at specific issues. Interventions based on behavior analytic.
Whole task training, forward chaining, and backward chaining techniques were compared in teaching two different step sequences of behavior to college students.
In Exp. 1 participants learned a sequence that began with easy movements, progressed through mote difficult movements, and ended with easy movements. Chaining is an instructional strategy grounded in applied behavior analysis (ABA) theory. Chaining is based on task analysis, whereby sub‐behaviors are recognized as requirements for task mastery.
One of two methods, forward chaining and.
