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
Flash Technique
Core mechanism: Brief interrupted exposure with positive memory engagement reprocesses disturbing memories without full activation
Ontology: Same AIP model as EMDR — dysfunctionally stored trauma memories

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.
Flash Technique
Philosophical roots: Same AIP model as EMDR; reconsolidation theory (Nader, 2000); titration principle from somatic traditions
Blind spots: Extremely new; minimal independent replication; unclear when minimal-activation processing is insufficient
Therapeutic voice: Think of your peaceful place. Keep that in mind while I tap. Let me know if anything shifts.
Choosing between them
Accelerated Resolution Therapy and Flash Technique 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.
