EB03 Disgust & Contamination
Emotional LayerMML-1

Version v2.0

Definition

An episodic program triggered by contamination cues (physical or symbolic), organizing avoidance, rejection, and expulsion to protect bodily and social boundaries.

Mechanism

Contamination-detection system activates rejection/avoidance; contact with the source is treated as harmful regardless of actual risk level.

Trigger–Appraisal–Function

• Trigger: Contamination cues (pathogen, decay, taboo contact).
• Appraisal: “Contact is harmful/contaminating.”
• Function: Protect boundaries via avoidance, rejection, or expulsion.

Observable Output

• Recoil/avoidance; distancing; refusal to touch/ingest.
• Attention to purity/contamination pathways (surfaces, proximity).
• Facial expressions (nose wrinkle), gag potential; cleaning impulses.
• Somatic: nausea-like sensations (variable).

Episode Profile

Onset: seconds. Peak: sharp aversive spike. Duration: minutes (often brief). Recovery: resolves with distance/cleansing; may leave avoidance bias. KEY METRIC: trigger sensitivity; avoidance/cleansing behaviors.

Dysregulation Risk

Contamination generalization; ritualized avoidance/cleansing cycles (OCD-adjacent patterns).

Change Potential

Regulation Trainability = Medium. Susceptibility Shift = Medium (learning, exposure, context).

Empirical Anchor

Disgust as basic emotion (Ekman, 1992; Rozin et al., 2008); pathogen-avoidance function; moral disgust extension (Haidt et al., 1997).
