Ever wondered why certain behaviors keep happening while others fade away? The secret often lies in three simple steps—what happens before, during, and after a behavior. In ABA Applied Behavior Analysis, this is called the ABC model: Antecedent → Behavior → Consequence.
According to the Association for Behavior Analysis International, focusing on these three pieces can help anyone—from parents to teachers—create more positive interactions and lasting change.
Let’s break it down in a way that actually makes sense in everyday life.
1. Antecedent: The Spark That Starts It All
Picture this: your child sees their favorite snack on the counter. That cue—the snack—is the antecedent, the trigger for what comes next. Recognizing these triggers helps us prevent frustration and set up success.
Identifying the right antecedents can reduce challenging behaviors before they even start.
2. Behavior: The Measurable Moment
In ABA, a behavior is something you can see and measure—like raising a hand, sharing a toy, or saying “help, please.” It’s not about guessing feelings but observing actions. Aspire Child & Family Services explains that clear, measurable behaviors make it easier to track progress and celebrate small wins.
3. Consequence: What Happens Next
The consequence is what follows the behavior—praise, a smile, or even no reaction at all. Positive reinforcement (like a simple “Great job!”) increases the chance the behavior will happen again. B.F. Skinner’s research showed that the right consequences can completely reshape habits over time.
Think of the ABC model like a ripple effect—shift the starting point, and the whole outcome changes. Sometimes, tweaking the before (the antecedent) is all it takes to create calmer, happier moments.
