Polyvagal Theory gives us the ladder.
ABA gives us the tools.
Together, we get the full picture of behavior from the inside out.
Polyvagal Theory, developed by Dr. Stephen Porges, helps us understand how the nervous system shifts between different states depending on whether we feel safe or threatened. These states shape how we behave, learn, and connect.
Here’s how it shows up in real life:
👩🏫 Ventral (Green Zone):
The system feels safe. The body is calm, socially engaged, and ready to learn.
→ This is the zone where ABA can teach, reinforce, and build meaningful skills.
🔥 Sympathetic (Orange Zone):
The body is mobilized fight or flight mode.
→ In this state, demands may feel threatening.
→ Our job is to reduce demands, offer movement, and support discharge of energy instead of pushing harder.
💤 Dorsal (Red Zone):
The system is in shutdown freeze, numbness, collapse.
→ Cognitive processing is offline.
→ Here, ABA must shift to quiet presence, safety-building, and reducing sensory overwhelm.
Why does this matter?
Because when we understand what state someone is in, we stop mislabeling trauma responses, nervous system survival strategies, or sensory overload as "noncompliance" or "problem behavior."
This is the evolution of behavior analysis:
💡 Behavior happens in the body — not just in response to external triggers.
💡 The nervous system tells us what the body can or can’t do in that moment.
💡 When we lead with safety, behavior change follows.
ABA is evolving. Are we evolving with it?
