Definition
Under-inhibition breakthrough: impulsive actions and decisions; lowered restraint.
Mechanism
Inhibition resources deplete; impulses pass through with reduced filtering and evaluation.
Typical Entry Conditions
• Depletion of inhibition resources (fatigue, alcohol, social overload)
• High reward cues + low monitoring
• After prolonged overcontrol (rebound)
• Group contagion: social disinhibition environments
• High reward cues + low monitoring
• After prolonged overcontrol (rebound)
• Group contagion: social disinhibition environments
Phenomenology
• Impulses break through; decisions speed up with less evaluation
• Higher risk-taking; social boundaries loosen
• Mood may lift; later regret/shame is possible
• Can escalate quickly if reinforced
• Higher risk-taking; social boundaries loosen
• Mood may lift; later regret/shame is possible
• Can escalate quickly if reinforced
Signature Dynamics
• C017Impulse Control ↓ → braking weakens; impulses pass through
• C105Play Drive ↑ → disinhibition has energizing, playful quality
• D031Risk Calibration ↓ → risk assessment distorted toward underestimation
• C105Play Drive ↑ → disinhibition has energizing, playful quality
• D031Risk Calibration ↓ → risk assessment distorted toward underestimation
Secondary Dynamics
Emotional Correlates
• Entry: E034Excitement ↑↑, E005Relief (from overcontrol) ↑
• During: E031Joy ↑↑, E034Excitement ↑
• Exit: E022Embarrassment ↑↑, E019Shame ↑, E021Regret ↑
• During: E031Joy ↑↑, E034Excitement ↑
• Exit: E022Embarrassment ↑↑, E019Shame ↑, E021Regret ↑
Measure
PRIMARY AXIS: Intensity (degree of impulse breakthrough — minor loosening vs major boundary collapse). SECONDARY: Frequency, Recovery (time and cost of aftermath).
Typical Exit Direction
Friction addition (delay, environment change) → inhibition reserve restoration (sleep/food). Post-episode repair if needed.
Risks & Misreads
• Financial/sexual/social risk escalation
• Relationship damage; reputation costs
• Can drift into Q021Inhibition Crash if brakes fully fail
• Relationship damage; reputation costs
• Can drift into Q021Inhibition Crash if brakes fully fail
Chronicity Note
Frequent recurrence suggests trait-level low C017Impulse Control or chronic overcontrol–rebound cycling. Investigate if Q019→Q020 oscillation is a stable pattern.
Empirical Anchor
Disinhibition (Whiteside & Lynam, 2001); ego depletion rebound; counterregulatory eating; abstinence violation effect.
Notes
Not inherently negative (can release creativity/social bonding), but cost depends on context. Different from Q040Creative-Insight Burst (disinhibition vs insight reorganization).
