Psychological & Physiological Response Management
When real violence hits, your body changes instantly. Heart rate spikes. Breathing shifts. Vision narrows. Hearing fades. Thinking collapses.
This module teaches how the mind and body behave under threat — and how to regain control fast.
After this module you will understand:
- The science of fear and adrenaline
- The freeze, fight, flight & fawn responses
- How the brain processes danger
- Performance zones under stress
- How to regain control of breathing, vision & thought
- How dissociation, panic & overload occur
1. The Threat Response System
Your nervous system has one job in danger: keep you alive. To do that, it switches between two modes:
Sympathetic Activation
- Heart rate spikes
- Breathing becomes shallow
- Vision narrows
- Hands shake
- Complex thinking shuts down
Parasympathetic Activation
- Body relaxes
- Thinking clears
- Breathing deepens
- Fine motor skills return
2. The 4 Primary Survival Responses
Freeze
The most misunderstood response. Freeze happens BEFORE fight or flight — it’s the “processing stall” while your brain assesses danger.
Fight
Not controlled aggression — but a chaotic, instinct-driven action surge.
Flight
Rapid withdrawal, often without conscious decision. Sometimes the best option.
Fawn
Appeasement behaviour — talking softly, negotiating excessively, hoping to avoid escalation.
3. Adrenaline, Heart Rate & Performance Zones
Your heart rate determines what kind of performance you are capable of.
Performance Breakdown
- Under 115 bpm = best decision-making
- 115–145 bpm = fast reaction but reduced clarity
- 145–175 bpm = tunnel vision, shaking
- 175+ bpm = thinking collapses, freezing likely
4. Perceptual Distortions
Under high stress your senses distort reality.
- Tunnel vision – only seeing what’s in front of you
- Auditory exclusion – sounds become muffled
- Time dilation – events feel slow or too fast
- Memory gaps – critical seconds vanish
- Distorted distance – attacker feels closer or further
Why this happens
Your brain is redirecting resources — from logic to survival systems.
5. Regaining Control – Fast Nervous System Reset Tools
These are the fastest ways to regain clarity under pressure.
A. Tactical Breathing (Combat Breathing)
- Inhale 4 seconds
- Hold 2 seconds
- Exhale 6 seconds
- Repeat 4–6 cycles
B. Peripheral Vision Reset
Shift attention from tunnel vision to the edges of your vision to calm the amygdala.
C. Grounding Cycle
- Name 1 thing you can see
- 1 thing you can hear
- 1 thing you can feel
D. Physical Pattern Interrupt
A small step, posture change or movement breaks freeze and re-engages decision-making.
6. Dissociation, Panic & Shutdown
Severe overwhelm causes the brain to shut down connection to the moment.
Symptoms
- Feeling “floaty” or unreal
- Watching yourself from outside your body
- Hearing becomes distant
- Memory fragments
How to Overcome
- Anchor yourself with sensation (touch something solid)
- Use deep exhale breathing
- Move your feet — motion resets dissociation
