Shaping Behavior in ABA: Techniques, Benefits & Applications

Key Points:

• Shaping behavior therapy is a gradual process where small steps towards a desired behavior are reinforced until the final behavior is achieved.
• It is a highly effective method in ABA for teaching complex skills by breaking them down into manageable components.
• Shaping behavior therapy can be applied to teach communication, social skills, self-help tasks, and more, particularly in children with autism.

When it comes to helping children with autism, Applied Behavior Analysis (ABA) has proven to be a highly effective method for encouraging positive behavior changes. In fact, studies show that about 64% of US children undergo ABA therapy. One of the most powerful techniques used in ABA is shaping behavior therapy, a gradual process that helps teach new skills by reinforcing successive approximations of a behavior.

In shaping behavior therapy, desired behaviors are not expected to happen all at once. Instead, they are broken down into small steps, and reinforcement is provided as the individual makes progress toward the final goal. This technique is particularly beneficial for teaching complex behaviors, such as learning how to speak, tie shoes, or initiate social interactions. 

Here is a quick rundown of what shaping behavior therapy is and how it works in practice:

What is Shaping Behavior Therapy?

Shaping behavior therapy is a process in which a therapist reinforces progressively closer approximations of a desired behavior until the individual can perform the target behavior. The term “shaping” refers to the way behaviors are gradually shaped and molded over time.

For example, if the goal is for a child to say "please," the therapist might begin by reinforcing any vocalization that resembles the word. As the child improves, the reinforcement is adjusted to only reward sounds that are closer to the word "please" until the child can say it clearly. The behavior is shaped step by step, using reinforcement to encourage each new stage.

This technique can be applied to any skill or behavior, from speaking and social interactions to self-help tasks like brushing teeth. It works by taking the target behavior, which may be complex or difficult to perform, and breaking it down into smaller, achievable parts.

How Does Shaping Behavior Therapy Work?

Shaping is a systematic, step-by-step process. Here's how it typically works:

1. Define the Target Behavior

The first step is to clearly define the target behavior. This could be anything from learning to say a word, using a fork to eat, or initiating a conversation with a peer. The behavior must be observable, measurable, and achievable.

2. Start with the Baseline Behavior

Next, you can identify where the individual currently is in relation to the target behavior. The starting point is typically a behavior the individual already performs, even if it's far from the desired goal. This gives a baseline from which to start shaping.

3. Reinforce Successive Approximation

Once the baseline is established, the therapist reinforces small steps that lead toward the target behavior. The key is that reinforcement is provided for actions that bring the individual closer to performing the target behavior.

4. Gradually Increase Criteria

As the individual begins to perform behaviors closer to the target behavior, the criteria for reinforcement become stricter. Only behaviors that more closely resemble the target behavior are reinforced, helping to guide the individual toward the final goal.

5. Fading Reinforcement

Over time, as the individual becomes more proficient, the reinforcement is faded. This means that reinforcement is given less frequently or only when the behavior is performed correctly. Eventually, the behavior is maintained without constant reinforcement.

Techniques Used in Shaping Behavior Therapy

There are several specific techniques used in shaping behavior therapy to help individuals progress toward their goals. Below are some of the most common strategies:

1. Positive Reinforcement

Positive reinforcement is at the core of shaping. By rewarding a behavior each time it occurs, you increase the likelihood that the behavior will happen again. In shaping, positive reinforcement is provided at each step toward the target behavior.

2. Differential Reinforcement

Differential reinforcement involves reinforcing only the behaviors that meet specific criteria while ignoring behaviors that do not align with the desired outcome. For example, if the goal is for a child to say "please," only attempts that closely resemble the word "please" are reinforced, while attempts that don’t are ignored.

3. Chaining

Chaining is often used in conjunction with shaping. It involves teaching a behavior chain in which each step leads to the next. For example, a child learning to tie their shoes would first learn the first part (e.g., holding the laces) before moving on to the next step (e.g., crossing the laces), and so on until the whole sequence is learned.

4. Prompting

Prompts are cues that guide an individual toward the desired behavior. These can be physical prompts, verbal prompts, or visual prompts. In shaping, prompts may be used at the beginning to encourage a behavior, with the goal of fading the prompt as the individual becomes more independent.

5. Task Analysis

Task analysis is a process in which a complex task is broken down into smaller, manageable steps. This can be especially helpful when using shaping for skills like brushing teeth or dressing. Each small task is taught individually, with reinforcement provided at each stage.

Benefits of Shaping Behavior Therapy

Shaping is an incredibly effective technique for teaching complex or new behaviors. Some of the benefits of shaping behavior therapy include the following:

Common Applications of Shaping Behavior Therapy

Shaping is widely used in ABA therapy to teach a variety of skills. Some common applications of shaping include:

1. Teaching Communication Skills

Whether it’s speaking, using sign language, or communication devices, shaping can be used to help children with autism learn how to express their needs and desires more effectively. Small vocalizations or gestures can be gradually shaped into full words or sentences.

2. Improving Social Skills

Shaping is highly effective in teaching social behaviors, such as making eye contact, greeting others, or starting a conversation. Reinforcement is provided for each step that brings the individual closer to interacting appropriately with others.

3. Self-Help Skills

Many individuals with autism struggle with self-help skills like dressing, eating, or brushing their teeth. Shaping can break these skills down into smaller components, with reinforcement provided for each step. Over time, the individual learns the entire task independently.

4. Reducing Challenging Behaviors

Shaping is also used to reduce problem behaviors, such as tantrums or aggression. By reinforcing appropriate alternatives, such as asking for help or using coping strategies, shaping helps individuals manage frustration and other emotions more effectively.
