"Fake It Until You Make It": Why ABA Doesn't Always Need the "Why" (1 of 3)
Updated: Sep 8
One of the most common misunderstandings about Applied Behavior Analysis is the idea that a child needs to understand why a behavior matters before they can learn to do it consistently. In practice, it is often the opposite. In ABA, a behavior becomes part of a child's repertoire long before they grasp the reasoning behind it, and for many kids, that is exactly how it should work.
The Courtroom Analogy
Picture someone walking into a courtroom wearing a tank top and shorts. The judge scolds them for dressing disrespectfully, even though, in that person's mind, they are simply wearing what feels comfortable. The next time, they show up in a suit. Did they suddenly develop a deep philosophical understanding of what respect means in a courtroom? Probably not. What changed is the consequence attached to the behavior. The ABCs, antecedent, behavior, consequence, did their job. Over time, showing up dressed appropriately becomes automatic, not because the person reasoned their way there, but because the behavior was shaped by what followed it.
This is precisely how we approach many social and adaptive skills in ABA. A child does not need to intellectually understand why a behavior is expected before they can learn to do it reliably. Typically developing kids often pick up these social cues naturally, through observation and mimicry. Children with autism frequently do not absorb those cues the same way, so we build the same ABCs deliberately, through consistent teaching and reinforcement, until the behavior becomes instinct. This antecedent-behavior-consequence framework is the foundation of ABA as described by Autism Speaks, and the CDC recognizes ABA as a leading evidence-based treatment approach for autism spectrum disorder.
"Thank You" Does Not Need to Mean Anything Yet
Consider a young child who says thank you after being handed something. Does that child understand the full social concept of gratitude and politeness? Almost certainly not. They say it because it gets a positive response, people smile, they get praised, and eventually the phrase becomes automatic in the right context. Nobody expects a three year old to have a philosophical grasp of etiquette before they are allowed to say thank you.
For a child with more significant support needs, teaching thank you as a repeated, reinforced response, until it becomes part of their natural repertoire, is not just acceptable. It is often the most effective way to build the skill at all. Peer-reviewed research measuring verbal behavior outcomes in ABA supports this approach: consistent, repeated reinforcement builds these skills over time, independent of a learner's conceptual understanding of them. For a child with stronger language and cognitive skills, we can eventually layer in the why, but for many learners, the behavior comes first, and it becomes instinctive because it is practiced, not because it is explained.
Whether "thank you" itself sits high or low on a given child's list of priority skills is actually a more complicated question than it first appears, and one we will dig into in a future post. But the core principle here, teaching the behavior first and letting understanding follow, applies regardless of where any single skill ranks.
Why This Matters for Parents
This principle can be reassuring for families who worry their child is just going through the motions rather than truly understanding a new skill. That is okay. Understanding often develops over time, sometimes well after a behavior is already solid. What matters most in the early stages is that the behavior becomes reliable, respectful, and functional, whether that is saying thank you, following a routine, or greeting someone appropriately. The insight can come later. The instinct comes first.
In our next post, we apply this same principle to language itself: how choosing fewer, more essential words can make functional communication clearer for a child who is just starting to build requesting skills.
At Imagination ABA Therapy, we build individualized treatment plans around exactly this principle, teaching skills in a way that fits how each child actually learns, not a one size fits all approach. We proudly accept NJ Medicaid with no waitlist for eligible families, and our team offers services in both English and Spanish.
