EMDR (Eye Movement Desensitization and Reprocessing)
Developed by Francine Shapiro in the late 1980s, EMDR is guided by the Adaptive Information Processing (AIP) model, which holds that trauma symptoms arise from distressing memories that were stored in a maladaptive, unprocessed form. EMDR aims to help the brain reprocess those memories toward an adaptive resolution.
It follows a standardized eight-phase protocol: (1) history-taking and treatment planning, (2) preparation and resourcing, (3) assessment of the target memory (image, negative and positive cognitions, emotion, body sensation), (4) desensitization, (5) installation of the positive cognition, (6) body scan, (7) closure, and (8) reevaluation. During desensitization the client holds the memory in mind while engaging in sets of bilateral stimulation — most often side-to-side (saccadic) eye movements, though tactile taps or auditory tones are also used — and is invited to notice whatever arises (a client-led, free-association stance).
ART (Accelerated Resolution Therapy)
Developed by Laney Rosenzweig, LMFT, in 2008, ART grew directly out of her EMDR practice; she kept the eye-movement component but re-engineered the procedure. ART uses smooth-pursuit eye movements— the client visually follows the therapist's hand as it moves back and forth — rather than EMDR's saccadic sets.
Its signature technique is Voluntary Image Replacement (VIR): the client mentally replaces the distressing images and sensations of the memory with new, self-selected images, while keeping the factual narrative of what happened— often summarized as “keep the knowledge, lose the pain.” ART is highly standardized and scripted (a directive, procedure-driven session), is typically brief (often 1–5 sessions), and is designed to be talk-optional: the client is not required to verbally recount the details of the trauma aloud, since the reprocessing is done through internal imagery.
