Applied Behavior Analysis (ABA) is a systematic and scientific approach to understanding behavior and improving social and learning outcomes. The core principles of ABA are:
-Behavior is purposeful
-Behavior can be changed
-Behavior is affected by the environment
-Replacement behaviors can be learned
-Behavior is affected by reinforcement

Applied behavior analysis (ABA) is a field of psychology that focuses on the observable and measurable effects of an individual’s environment on their behavior. ABA therapists work with individuals who have developmental disabilities, such as autism, to help them develop new skills and reduce problem behaviors.
The core principles of ABA are based on the idea that all behavior is learned and that it can be changed through reinforcement or punishment. ABA therapists use these principles to design customized treatment plans for each individual they work with.
The core principles of ABA are:
-Reinforcement: behaviors that are followed by a desirable consequence are more likely to be repeated.
-Punishment: behaviors that are followed by an unpleasant consequence are less likely to be repeated.
-Extinction: ceasing to reinforce a behavior will cause it to eventually stop occurring.
-Shaping: reinforcing successively closer approximations of a desired behavior until the desired behavior is achieved.
-Generalization: teaching new skills in different contexts to help the individual learn how to transfer those skills to other areas of their life.
The Three Core Principles of Applied Behavior Analysis
Applied Behavior Analysis is based on three core principles: reinforcing desired behavior, reducing undesired behavior, and using data to make decisions. In this article, we will discuss each of these core principles in detail.
The Principle of Reinforcement
Reinforcement is anything that increases the likelihood that a desired behavior will be repeated. There are two types of reinforcement: positive and negative. With positive reinforcement a desirable consequence (a reward) is presented after the desired behavior is displayed, in order to increase the likelihood of that behavior being repeated in the future. With negative reinforcement, an unpleasant or undesired consequence (punishment) is removed after the desired behavior is displayed, in order to increase the likelihood of that behavior being repeated in the future. In either case, the goal is to increase the likelihood of the desired behavior being repeated.
The Principle of Punishment
The principle of punishment states that if a behavior is followed by an unpleasant consequence, the behavior is less likely to happen again in the future. For example, if a child tantrums and is then placed in time-out, the child is likely to tantrum less in the future because they have learned that tantruming leads to an unpleasant consequence.
The Principle of Shaping
The principle of shaping is based on the idea that behavior can be molded and changed by reinforcing successive steps towards the desired behavior. For example, if you wanted to train a dog to sit, you would start by rewarding them for standing still. Once they consistently stand still when prompted, you would then begin to reward them only when they lower their behinds towards the ground. Finally, you would only reinforce the behavior once they are sitting completely down. This process of gradually reinforcing closer and closer approximations of the desired behavior is known as shaping.
How the Three Core Principles are Used in ABA
Applied Behavior Analysis is a science that uses principles of behavior to change behavior. The three core principles are reinforcement, punishment, and extinction. In this article, we will discuss how these three core principles are used in applied behavior analysis
The Principle of Reinforcement
Reinforcement is defined as any consequence that will increase the likelihood of a behavior being repeated. In other words, it makes something more likely to happen again. There are two kinds of reinforcement: positive and negative.
Positive reinforcement occurs when a behavior is followed by a reinforcer (something that increases the likelihood of that behavior being repeated). For example, if a child gets a piece of candy after sitting still for 5 minutes, the child is more likely to sit still for 5 minutes again in the future because he wants the candy. In this case, the candy is the reinforcer.
Negative reinforcement occurs when a behavior is followed by the removal of an unpleasant condition (something that increases the likelihood of that behavior being repeated). For example, if a child stops whining when his teacher gives him attention, the child is more likely to whine again in order to get attention from his teacher. In this case, the attention from the teacher is reinforcing because it removes the unpleasant condition (being ignored) for the child.
The Principle of Punishment
The principle of punishment is used in ABA to decrease the likelihood of a certain behavior occurring again in the future. Punishment is used after a behavior has already occurred, and it is meant to reduce the likelihood of that behavior happening again. There are two types of punishment: positive punishment and negative punishment.
Positive punishment is when something is added after a behavior occurs, in order to decrease the likelihood of that behavior happening again. An example of positive punishment would be if a child hits another child and then is given a time-out. The time-out would be the positive punishment because it is something that is added (the child is taken away from the fun activity) after the undesired behavior (hitting another child) occurred.
Negative punishment is when something is taken away after a behavior occurs, in order to decrease the likelihood of that behavior happening again. An example of negative punishment would be if a child hits another child and then has his toy taken away. The toy being taken away would be the negative punishment because it is something that is taken away (the child can no longer play with his toy) after the undesired behavior (hitting another child) occurred.
Punishment can be an effective way to decrease problematic behaviors, but it must be used correctly and consistently in order for it to work well. If you are thinking about using punishment as a way to decrease a certain behavior, it is important to talk to an ABA professional first, so that they can help you determine if punishment is likely to be an effective solution for your particular situation.
The Principle of Shaping
The principle of shaping is one of the three core principles of Applied Behavior Analysis (ABA). Shaping is a process whereby a behavior is gradually learned by reinforcing successive approximations of that behavior. In other words, it involves reinforcing a behavior that is close to the desired behavior, until the desired behavior is eventually learned.
For example, if a child is learning to put on their clothes, they may start by putting on their shirt. Once they have mastered putting on their shirt, they may move on to putting on their pants. By reinforcing each successive approximation, the child will eventually learn the desired behavior (putting on all their clothes).
The principle of shaping can be used to teach any desired behavior, no matter how simple or complex. It is an important tool in the ABA toolbox and can be used to great effect in helping children with autism spectrum disorder (ASD) and other developmental disabilities to learn new skills and behaviors.
The four principles of ABA are:
– positive reinforcement,
– negative reinforcement,
– punishment, and
ABA therapy strives to increase desirable behaviors and decrease undesirable ones. The therapist works with the individual to identify their goals and then develops a treatment plan aimed at helping the individual reach those goals. ABA therapy is usually provided in one-on-one sessions, but it can also be provided in a group setting.
