Protection

Threat-response regulatory configuration with sympathetic or dorsal vagal activation.

Pattern B represents the nervous system's configuration when neuroception registers threat—activating the survival responses that evolved to protect organisms from danger. This is not pathology. Pattern B is intelligent biological design. The fight-flight-freeze-fawn responses exist because they solved survival problems across millions of years of evolution.

Key distinction: Pattern B is appropriate when actual threat is present. The clinical question is not "how do we eliminate Pattern B?" but "is current activation proportionate to actual present danger—or is the system responding to learned patterns from the past?" When the nervous system becomes stuck in Pattern B—unable to return to Pattern A when threat resolves—what was adaptive becomes constraining.

The Four F Responses

Pattern B manifests through four primary response types based on autonomic state and perceived threat options.

Response	Autonomic State	Function	Presentation
Fight	Sympathetic dominant	Engage and overcome threat	Aggression, confrontation, assertion
Flight	Sympathetic dominant	Escape threat	Avoidance, withdrawal, distancing
Freeze	Dorsal vagal dominant	Become invisible to threat	Immobilization, dissociation, shutdown
Fawn	Mixed sympathetic/dorsal	Appease threat	Compliance, people-pleasing, self-abandonment

Neurophysiological Configuration

Dimension	Pattern B Characteristics
Primary State	Sympathetic activation (fight/flight) OR dorsal vagal (freeze/collapse)
Secondary Systems	Ventral vagal offline; social engagement inhibited
Heart Rate Variability	Low; indicating autonomic rigidity
Respiratory Pattern	Rapid, shallow (sympathetic) or slow, shallow (dorsal)
Muscle Tone	Braced/tense (sympathetic) or collapsed/limp (dorsal)
Facial Expression	Flat or tense; social engagement muscles inhibited
Vocal Prosody	Monotone or pressured; does not communicate safety

Multi-Dimensional Pattern Profile

Axis	Configuration	Clinical Implications
Nervous System State	Sympathetic activation or dorsal collapse; ventral offline	Baseline oriented to defense; recovery impaired
Biological Activation	Hyperaroused (fight/flight) or hypoaroused (freeze); rapid cycling possible	Physiological resources directed to survival
Cognitive Frame	Narrow, binary, threat-focused; nuance unavailable	Insight limited by threat processing; timing matters
Empathy Logic	Selective; in-group preferenced; out-group threatening	Relational interventions require safety establishment first
Behavioral Expression	Defensive, protective, avoidant, or appeasing	Observable survival behaviors; not character

Capacities and Constraints

What Becomes Available

Capacity	Expression	Function
Rapid threat response	Immediate reaction without deliberation	Speed over accuracy when stakes are survival
Boundary energy	Force available for self-protection	Resource for establishing safety
Hypervigilance	Constant environmental scanning	Maximizes early threat detection
Pain tolerance	Reduced sensitivity during activation	Enables continued function under threat
Focused attention	Concentration on threat source	Eliminates distracting information

What Becomes Constrained

Capacity	How Constrained	Mechanism
Broad perception	Tunnel vision; only threat-relevant data processed	Perceptual narrowing serves rapid response
Cognitive flexibility	Binary, all-or-nothing thinking	Nuance is luxury; survival requires simplicity
Empathy access	Reduced to in-group; out-group becomes threat	Resources redirected from connection to protection
Learning	New information rejected if inconsistent with threat model	Updating templates is dangerous during threat
Repair capacity	Rupture feels like danger, not opportunity	Conflict activates survival, not curiosity

State-Dependent Emotional Function

In Pattern B, emotions function as survival signals—organizing rapid response to perceived threat rather than providing nuanced information.

Emotion	Pattern B Function	Distinguishing Features
Anger	Aggressive, reactive; aimed at eliminating threat	Disproportionate to stimulus; destructive rather than clarifying
Fear	Anxious, pervasive; generalized to ambiguous stimuli	Not calibrated to actual danger; anticipatory rather than responsive
Guilt	Becomes shame; "I am bad" rather than "I did wrong"	Paralyzing rather than action-oriented
Shame	Annihilating; core self feels defective	Isolation-inducing; prevents repair-seeking
Sadness	Collapsed, hopeless; withdrawal from support	Isolating rather than connection-seeking
Envy	Hostile; "they shouldn't have it"	Threat-framed; comparison as competition
Joy	Manic or absent; unstable or inaccessible	Either dysregulated or suppressed
Love	Anxious, clinging; fear of loss dominant	Attachment activated but disorganized
Trust	Suspicious, verification-seeking	Given reluctantly; withdrawn quickly
Hope	Fragile or absent; future feels threatening	Present survival dominates orientation

When Pattern B Is Appropriate

Pattern B is not inherently problematic. It is the appropriate response to genuine threat.

Marker	Description
Proportionality	Activation matches actual threat level
Temporality	State is temporary; resolves when threat resolves
Specificity	Response targets actual threat source
Recovery	Return to Pattern A occurs when safety is restored
Learning	Experience updates threat templates appropriately

Clinical principle: The goal is not elimination of Pattern B but restoration of flexibility—the capacity to activate when needed and return when safe.

When Pattern B Becomes Chronic

Problems emerge when Pattern B becomes the default—when the nervous system remains in threat response despite the absence of current danger.

Presentation	Characteristics	Common Misattributions
Chronic hypervigilance	Always scanning; exhausted but can't relax	"Anxiety disorder," "control issues"
Reactive aggression	Quick to fight; easily triggered	"Anger management problem," "personality disorder"
Avoidant withdrawal	Persistent flight from intimacy or challenge	"Avoidant attachment," "antisocial"
Freeze states	Dissociation, numbness, inability to act	"Depression," "laziness," "lack of motivation"
Chronic appeasement	Persistent fawn; unable to assert needs	"Codependency," "low self-esteem"

Clinical implication: These presentations are often treated as character or disorder. Understanding them as chronic Pattern B—stuck survival response—changes intervention from "fix the person" to "provide what the nervous system needs to release."

Working with Pattern B

Pattern B intervention prioritizes safety provision over insight. The nervous system must experience safety before it can release defensive posture.

Priority	Focus	Approaches
1. Stabilization	Establish baseline safety	Grounding, resourcing, co-regulation
2. Regulation capacity	Build ability to modulate activation	Somatic interventions, nervous system education
3. Relational safety	Demonstrate that connection is survivable	Consistent presence, rupture-repair, titrated vulnerability
4. Processing	Address stuck threat responses	EMDR, Somatic Experiencing, trauma-focused approaches
5. Integration	Update templates with new experience	Meaning-making, narrative work, corrective experience

What Facilitates Release

Co-regulation
Predictability
Titrated exposure
Completion of defensive responses
Time and choice

What Impedes Release

Insight before safety
Exposure without titration
Rushing
Inconsistency
Shaming the defense

Pattern B is not a problem to be solved.

It is the nervous system's intelligent response to threat—a response that has protected organisms for millions of years.

The clinical task is not to eliminate Pattern B but to restore choice—the capacity to enter when needed and return when safe.
