Definition
Abrupt narrowing of the cognitive field to one detail/hypothesis; context and alternatives drop out.
Mechanism
Attentional narrowing overrides contextual processing; one detail captures the cognitive field.
Typical Entry Conditions
• Complex problem under stress → attention clamps on a single cue
• Ambiguous situations with a salient detail (headline, message, symptom)
• High stakes + time pressure; low tolerance for uncertainty
• After criticism/shock where one interpretation dominates

• High stakes + time pressure; low tolerance for uncertainty
• After criticism/shock where one interpretation dominates
Phenomenology
• Context and alternatives drop out; one detail becomes “the whole picture”
• Reduced hypothesis maintenance; confirmation bias increases
• Social input is discounted; argument becomes repetitive
• Can feel like clarity while actually reducing accuracy

Signature Dynamics
• C001Attentional Stability ↑ (maladaptive) → attention clamps; cannot disengage
• C002Attention Switching Speed ↓ → switching suppressed
• D062Sensemaking Under Ambiguity ↓ → multiple-interpretation capacity collapses
• C002Attention Switching Speed ↓ → switching suppressed
• D062Sensemaking Under Ambiguity ↓ → multiple-interpretation capacity collapses
Secondary Dynamics
Emotional Correlates
• Entry: E002Anxiety ↑↑, E004Dread ↑
• During: E008Frustration ↑↑, E040Surprise ↑
• Exit: E021Regret (if decision was poor) ↑↑, E005Relief ↑
• During: E008Frustration ↑↑, E040Surprise ↑
• Exit: E021Regret (if decision was poor) ↑↑, E005Relief ↑
Measure
PRIMARY AXIS: Intensity (degree of context loss — how much drops out of view). SECONDARY: Duration, Threshold (how much stress triggers narrowing).
Typical Exit Direction
Forced alternative generation (write 3 options) + context re-expansion. Resolves once arousal drops and external review re-enters.
Risks & Misreads
• Bad decisions due to missing context
• Interpersonal conflict (others feel unheard)
• Can drift into Q027Single-Hypothesis Lock if sustained
• Interpersonal conflict (others feel unheard)
• Can drift into Q027Single-Hypothesis Lock if sustained
Chronicity Note
Frequent recurrence suggests trait-level low C010Cognitive Flexibility or chronic stress load. Investigate stress ecology and D063Cognitive Switching Hygiene.
Empirical Anchor
Attentional narrowing under stress (Easterbrook, 1959); tunnel vision in aviation/medical error research; weapon focus effect.
Notes
Distinct from Q027Single-Hypothesis Lock: Q014 is an attention problem (perceptual narrowing); Q027 is a belief problem (interpretive certainty). The signature dynamics are intentionally differentiated.
