Leading the Way in Trauma Therapy


The Flash technique is a recently developed therapy procedure that involves having the client at least partially resolve a traumatic memory without consciously engaging it.

Briefly, Flash involves having the client concentrate on a positive, engaging image while also concentrating on a distraction stimulus such as the therapist's moving hand, or the therapist counting aloud. Every so often, the therapist says "Flash" at which point the client is to blink, not access the targeted trauma memory, and continue concentrating on the positive image. Most of the time this leads to the client fully or partially processing the memory, much as occurs in other memory reconsolidation (trauma healing) methods.

Preliminary research has found Flash to be non-distressing, safe, rapid, and effective. Trauma Institute is involved in several current/ongoing Flash studies. We also use Flash in our intensive therapy (along with EMDR or PC), include Flash training in our EMDR and PC training programs, and occasionally provide Flash training to other therapists as well.
