EB03 Disgust & Contamination
Emotional LayerMML-4

Version v2.0

Definition

A peak-intensity disgust episode triggered by strong contamination cues, organizing immediate rejection/expulsion (gagging, recoil) and rapid disengagement.

Mechanism

Contamination detector fires at maximum intensity; expulsion reflexes activate before cognitive evaluation completes.

Trigger–Appraisal–Function

• Trigger: Strong contamination cue (graphic, close, intense).
• Appraisal: “Must expel/avoid immediately.”
• Function: Immediate expulsion/rejection to prevent contact/ingestion.

Observable Output

• Gag/recoil; urgent withdrawal; intense facial/motor rejection.
• Rapid interruption of ongoing action; refusal/disengagement.
• Strong avoidance learning; reluctance to re-approach.
• Somatic: nausea, retching impulses (common).

Episode Profile

Onset: instant–seconds. Peak: explosive. Duration: seconds–minutes. Recovery: rapid offset after distance; strong residual aversion. KEY METRIC: expulsion markers; avoidance strength.

Dysregulation Risk

Trauma-like pairing with unrelated cues via strong conditioning; over-generalized avoidance.

Change Potential

Regulation Trainability = Low–Medium. Susceptibility Shift = Medium (conditioning and exposure possible but slower).

Empirical Anchor

Peak disgust / emetic reflex; conditioned taste aversion (Garcia & Koelling, 1966).
