Introduction to ABA

Updated: Mar 27, 2023

What is ABA?


Applied Behavior Analysis (ABA) is a scientific approach to understanding behavior and how it can be modified to improve quality of life. It is based on the principles of behaviorism, in which behaviours are learnt through the consequences of our actions. ABA has been used to treat a wide range of conditions, including autism spectrum disorder, developmental disabilities, and behavior disorders.

One of the core principles of ABA is the use of positive reinforcement to increase desired behaviors. Positive reinforcement involves providing a reward or incentive for a behavior, which increases the likelihood of that the behavior occuring again in the future. This can be as simple as offering praise or a tangible reinforcement for completing a task or demonstrating a desired behavior.


How does ABA work?


ABA involves breaking down complex behaviors into smaller, more manageable steps. This is known as task analysis. By breaking down a behavior into smaller steps, it becomes easier to teach and learn. For example, if the desired behavior is to tie shoelaces, a task analysis might break down the steps into: 1) pick up laces, 2) cross them over, 3) loop one lace over the other, 4) pull tight, and 5) repeat with other lace.

Another key component of ABA is data collection and analysis. ABA practitioners use data to track progress, identify patterns, and make informed decisions about treatment plans. This data might include information about the frequency and duration of specific behaviors, as well as the types of rewards or consequences that are most effective for modifying those behaviors.


ABA and Autism Spectrum Disorder


ABA has been widely used to treat individuals with autism spectrum disorder (ASD). The principles of ABA are particularly effective for helping individuals with ASD learn new skills and behaviors, as well as reducing inappropriate behaviors. For example, ABA can be used to teach communication skills, social skills, and self-care skills. It can also be used to address challenging behaviors, such as aggression or self-injury.

ABA practitioners are trained to use positive reinforcement and other strategies in a safe and effective way.
