How they work
Accelerated Resolution Therapy
Core mechanism: Smooth pursuit eye movements during trauma recall + voluntary image replacement → reconsolidation of the memory with reduced distress while keeping narrative knowledge intact
Ontology: Traumatic memories are stored with somatic and emotional distress that can be separated from the narrative content through directed reconsolidation
EMDR
Core mechanism: Bilateral stimulation during trauma memory processing facilitates adaptive information processing and memory reconsolidation (proposed)
Ontology: Unprocessed trauma memories stored dysfunctionally with original affect, sensation, and cognition

What each assumes — and misses
Accelerated Resolution Therapy
Philosophical roots: Memory reconsolidation theory (Nader, 2000); Shapiro (AIP model — adapted); pragmatism (rapid results); image replacement has no clear philosophical antecedent
Blind spots: Relatively new; mechanism not well understood; voluntary replacement raises questions about whether processing actually occurs vs. avoidance; limited independent replication
Therapeutic voice: Hold that image in mind while you follow my hand. Now I want you to replace that scene with anything you'd rather see.
EMDR
Philosophical roots: Merleau-Ponty (body holds memory); Bion (processing/containment); Pavlov (orienting response); Shapiro (adaptive information processing — pragmatic, not philosophically derived)
Blind spots: Mechanism debate unresolved; protocol fidelity varies; may be applied to conditions beyond its evidence base
Therapeutic voice: Bring up the image and the negative belief. Notice what you feel in your body. Now follow my fingers.
Choosing between them
Accelerated Resolution Therapy and EMDR both sit within the Trauma-Focused tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
