What Is Working Memory Theory in EMDR?
Working memory theory proposes that recalling a distressing memory while simultaneously performing a demanding eye-movement task creates competition for limited cognitive resources. That competition may make the memory feel less vivid and less emotionally intense. It is one of the strongest current explanations for the eye-movement component of EMDR.
What Does Research Actually Say About Eye Movements in EMDR?
EMDR is well established as a trauma treatment, but a different question is whether the eye movements themselves contribute something important. Laboratory and clinical research suggests that they do affect emotional memory—especially vividness—but the science is more nuanced than “bilateral stimulation rewires the brain.”
Why Do Eye Movements Help With Distressing Memories?
Eye movements are used in both EMDR and Accelerated Resolution Therapy, or ART. Research suggests that recalling a distressing memory while simultaneously performing a demanding eye-movement task can make the memory less vivid and, to a lesser degree, less emotionally intense. The exact mechanism is still being studied.
ART vs. EMDR: How Is Bilateral Stimulation Used Differently?
ART and EMDR are often grouped together because both use eye movements. But eye movements are only one part of each therapy. EMDR typically uses bilateral stimulation within a more associative reprocessing process, while ART uses repeated eye-movement sets within a more directive sequence involving memory recall, body sensations, and imagery rescripting.
How Does Bilateral Stimulation Work in EMDR?
How does bilateral stimulation work in EMDR? Research suggests eye movements may tax working memory while a distressing memory is recalled, reducing its vividness and emotional intensity. Learn what scientists know—and what remains uncertain.
