Definition
A lock in verbal production: speaking and formulating become hard or impossible under overload.
Mechanism
Evaluation pressure disrupts speech planning; verbal production stalls while nonverbal channels remain active.
Typical Entry Conditions
• High evaluation pressure (speaking under observation)
• Overload + threat arousal (fight/flight readiness disrupts speech planning)
• Conflict situations with high stakes and low psychological safety
• After shock/startle events where formulation stalls
• Overload + threat arousal (fight/flight readiness disrupts speech planning)
• Conflict situations with high stakes and low psychological safety
• After shock/startle events where formulation stalls
Phenomenology
• Verbal production stalls: difficulty finding words, forming sentences, or initiating speech
• Nonverbal signals may increase (gestures, withdrawal) while words “freeze”
• Cognitive load spikes when trying to speak; speech becomes effortful
• Often followed by shame/embarrassment about “not being able to talk”

Signature Dynamics
• C085Verbal Expressiveness ↓ → speech production collapses
• C069Social Anxiety ↑ → evaluation pressure drives the lock
• D022High-Pressure Communication ↓ → speaking-under-pressure skill fails
• C069Social Anxiety ↑ → evaluation pressure drives the lock
• D022High-Pressure Communication ↓ → speaking-under-pressure skill fails
Secondary Dynamics
Emotional Correlates
• Entry: E002Anxiety ↑↑, E004Dread ↑
• During: E042Shock ↑↑, E019Shame ↑
• Exit: E019Shame ↑↑, E022Embarrassment ↑
• During: E042Shock ↑↑, E019Shame ↑
• Exit: E019Shame ↑↑, E022Embarrassment ↑
Measure
PRIMARY AXIS: Threshold (what level of social pressure triggers the lock). SECONDARY: Duration (seconds to minutes), Latency (how quickly speech degrades after trigger).
Typical Exit Direction
Arousal downshift + channel switching (writing/typing). Resolves quickly once social pressure drops.
Risks & Misreads
• Misread as defiance or manipulation in conflict contexts
• Self-blame can create anticipatory anxiety → higher recurrence
• Over-forcing speech can worsen lock
• Self-blame can create anticipatory anxiety → higher recurrence
• Over-forcing speech can worsen lock
Chronicity Note
Frequent recurrence suggests trait-level high C069Social Anxiety. If context-stable, investigate social anxiety patterns.
Empirical Anchor
Social anxiety-linked speech disruption; verbal fluency under stress (Eysenck et al., 2007 attentional control theory).
Notes
Distinct from general low verbal skill (acute onset under load/threat). Often co-occurs with Q012Freeze Mode; differentiate by dominant signature (speech vs motor immobility).
