Window of Tolerance & Nervous System Capacity Screener (Dr. Dan Siegel Polyvagal Model)

Framework: Dr. Dan Siegel Autonomic Arousal Model & Dr. Stephen Porges Polyvagal Theory · 100% Private & Free

Assess whether your nervous system operates in a resilient wide zone or gets easily thrown into fight-or-flight panic (hyperarousal) or dorsal freeze collapse (hypoarousal).

Scientific Overview

The Window of Tolerance describes the optimal zone of autonomic nervous system arousal where you can process emotions, navigate daily stressors, and think clearly. When trauma or chronic burnout constricts this window, minor triggers catapult the body into hyperaroused panic or drop it into hypoaroused numbness and freeze.

What This Assessment Evaluates

  • Measures Sympathetic Hyperarousal (Fight/Flight/Panic), Dorsal Hypoarousal (Freeze/Shutdown/Numbness), and Micro-Window Fragility
  • Explains the neurobiology of the myelinated vagal brake, heart rate variability, and insular awareness
  • Step-by-step somatic pendulation, low-frequency vocal toning, and physiological sigh de-escalation drills

How to Take This Test

  1. Answer honestly based on your experience over the past 7 days.
  2. There are no right or wrong answers; trust your initial emotional reaction.
  3. Receive your personalized score breakdown, mascot insight, and custom journaling prompts immediately.

Frequently Asked Questions

What does it feel like to be outside your Window of Tolerance?

Above the window (hyperarousal), you feel wired, angry, racing thoughts, and sensory overload. Below the window (hypoarousal), you experience mental fog, emotional numbness, physical exhaustion, and couch-lock paralysis.

Can you widen your Window of Tolerance permanently?

Yes. Consistent somatic practices (such as vocal vagus stimulation, physiological sighs, and daily unpressured voice journaling in Nuju) rewire neuroception and widen autonomic capacity over time.
