Imagine trying to teach a child how to raise their hand in class or how to say ‘thank you’ when given something. As an ABA therapist, my job is to figure out how the world around the child can be adjusted to make these behaviors more likely to happen.
That’s where behavior-altering effects come in. These are the strategies we use to modify how children behave by changing things that happen before and after the behavior itself. Let me walk you through how this works and how it can make all the difference in therapy.
What are Behavior-Altering Effects in ABA?
Before we get into the details, let’s break down what a behavior-altering effect is. In ABA, we focus on behavior—any action that can be observed and measured. It could be something as simple as a child picking up a toy or as complex as a teenager managing their emotions in a social setting.
Behavior-altering effects are the factors that influence or change how often these behaviors happen. So, when we talk about “altering” behavior, we mean using specific strategies and interventions to make certain behaviors more likely (like learning to ask for help) or less likely (like stopping unwanted behaviors, such as aggression or tantrums).
These effects can be antecedent-based (what happens before the behavior) or consequence-based (what happens after the behavior). By understanding both types of effects, ABA therapists are able to adjust the environment and responses to either promote positive behaviors or reduce unwanted ones.
Why Do Behavior-Altering Effects Matter?
Why is it important to understand behavior-altering effects? The answer is simple: because ABA therapy’s main goal is to improve the quality of life for individuals, especially those with autism. This is done by increasing desirable behaviors (like communication, self-control, or social skills) and decreasing undesirable behaviors (like aggression or self-injury).
ABA therapy is not about punishing individuals for doing something wrong; it’s about teaching and reinforcing positive behaviors. By using behavior-altering effects effectively, therapists can create an environment that supports learning and growth.
Think about it this way: If a child is trying to learn how to say “please” before getting a toy, you would want to reinforce that behavior every time it happens. Likewise, if they throw a tantrum to avoid cleaning up, a consequence-based strategy can help decrease that behavior over time. These small, targeted interventions are the building blocks of successful behavior change.
Types of Behavior-Altering Effects in ABA
In ABA, there are two main types of behavior-altering effects: antecedent-based effects and consequence-based effects. Both of these play a role in helping to modify behavior, but they focus on different parts of the behavior cycle.
Antecedent-Based Effects: What Happens Before the Behavior
Antecedents are events that occur before a behavior happens. They are the triggers or cues that prompt a person to behave in a certain way. In ABA, altering the antecedents can make it easier for individuals to engage in desired behaviors.
Let’s say you’re working with a child who often refuses to ask for help in the classroom. An antecedent-based intervention might involve setting up visual cues that remind the child to raise their hand when they need help. These cues help prompt the child to engage in the desired behavior (asking for help) before the behavior even takes place.
Here are some common antecedent-based strategies used in ABA:
- Prompting: Giving hints or cues to help the person engage in the desired behavior. This could include verbal cues (e.g., “Remember to say please”) or physical prompts (e.g., guiding the hand to a correct position).
- Environmental Changes: Modifying the environment to make it easier for the person to succeed. For example, reducing noise or distractions can help a child focus better on their tasks.
- Visual Supports: Using pictures or visual schedules to remind the individual what they should do next, such as a visual timer for transitions or a chart to encourage positive behaviors.
Antecedent-based strategies work by setting up the person for success before the behavior even occurs.
Consequence-Based Effects: What Happens After the Behavior
Consequences refer to what happens right after a behavior occurs. In ABA, consequences can either reinforce a behavior (making it more likely to happen again) or punish a behavior (making it less likely to happen again). These effects are key in shaping behavior over time.
The two primary types of consequences in ABA are:
- Reinforcement: This is used to increase the likelihood of a behavior being repeated. Reinforcement can either be positive or negative.
- Positive Reinforcement: Adding something pleasant to encourage a behavior. For example, when a child says “thank you” after receiving a gift, they might receive praise or a small treat.
- Negative Reinforcement: Removing something unpleasant to encourage a behavior. For example, a child who cleans up their toys might avoid a time-out.
- Punishment: The goal of punishment is to reduce the likelihood of an undesired behavior happening again. Similar to reinforcement, punishment can be positive or negative.
- Positive Punishment: Adding something unpleasant to decrease a behavior. For example, a child who refuses to do homework might be given extra chores as a consequence.
- Negative Punishment: Removing something pleasant to decrease a behavior. For example, if a child throws a tantrum, they might lose access to screen time for the day.
By carefully choosing the appropriate consequence for each behavior, therapists can guide individuals toward more positive behaviors and discourage those that might be harmful or disruptive.
The Role of Behavior-Altering Effects in Achieving Long-Term Success
One of the greatest strengths of ABA therapy is its ability to create lasting behavior changes. It’s not about short-term fixes but about establishing long-term, positive habits.
Whether the goal is to improve social skills, reduce tantrums, or teach independence, behavior-altering effects play a critical role in ensuring that the interventions work and produce meaningful, lasting change.
Using a combination of antecedent-based and consequence-based strategies, ABA therapists can tailor interventions to meet each person’s unique needs. The key is consistency, patience, and the understanding that behavior change doesn’t happen overnight—it’s a gradual process.

FAQs
- What is the main goal of ABA therapy?
The main goal of ABA therapy is to increase positive behaviors and reduce negative behaviors through structured interventions. By focusing on behavior modification, ABA helps individuals learn new skills and adapt to their environments more effectively.
- How does reinforcement work in ABA therapy?
Reinforcement in ABA therapy strengthens desired behaviors by adding something pleasant (positive reinforcement) or removing something unpleasant (negative reinforcement) after the behavior occurs. This makes the behavior more likely to be repeated in the future.
- How long does it take for ABA therapy to work?
The length of time it takes for ABA therapy to produce results depends on the individual’s needs and the complexity of the behaviors being targeted. However, with consistent and individualized therapy, many individuals start to show progress within a few weeks to months.
