PTSD & Acute Trauma

Population and scope: Adult traffic-accident survivors with traumatic-stress symptoms; a PTSD diagnosis was not required.

Randomized studies

Yaşar et al. (2022) randomized 68 participants to online group Flash or stress-management psychoeducation; only 39 completers were analyzed. Some self-reported traumatic-stress outcomes favored Flash at one month. Attrition, short follow-up and absent preregistration limit interpretation. This is not evidence of diagnostic remission, equivalence to standard EMDR, or effectiveness for complex PTSD.

How they work

Accelerated Resolution Therapy

Core mechanism: Smooth pursuit eye movements during trauma recall + voluntary replacement of the distressing image → the client keeps the narrative of what happened while the image loses its charge; ART explains this as memory reconsolidation, which is a borrowed hypothesis rather than a demonstrated finding for this protocol

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: Attention stays on a positive image while the client briefly glances at the target memory; this is proposed to reduce the memory's charge without fully activating it

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: Stay with the peaceful place. You don't need to go anywhere near the memory. When I say 'blink,' give me three quick blinks, then come right back here.

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.
