What is ABA?




What is Applied Behaviour Analysis or commonly known as ABA? ABA is a science of behaviours. It helps us understand why behaviours occur and how learning takes place. With a comprehensive knowledge of ABA, we can create effective technologies/procedures that help us improve behaviors, teach new skills and ultimately improve lives.


Basic principles of ABA such as reinforcement, punishment, and motivation can be observed within our environment at all times. Think about the last time you got a speeding ticket; are you more careful now making sure that you keep to the speed limit especially on the road where you’ve gotten a ticket? How about that time where you chose to use e-wallet to pay for something instead of using cash so that you can earn some points? Or maybe that time where you hopped into your car and drove 2 hours just to have that bowl of noodles or that slice of cake?


Even though ABA is everywhere, it is most commonly known as an effective approach for learners with developmental delays and autism because of the early application of the science with these specific population. However, these aren’t the only areas that ABA has been proven to be effective. Here are some examples of areas where ABA is making its contribution.




As Behavior Analysts, we utilize the science of ABA to teach skills that are important and meaningful to the children we serve. We work closely with family members, teachers, and caregivers to help them understand the principles of learning and how these principles can be utilized in their everyday interactions with the children.
