Dual Attention Stimuli

During phases 4 through 6 of EMDR1 [see A Brief Description of EMDR for more information on the eight phases of EMDR] clients focus on their distressing or desired experiences at the same time as they attend to a dual attention stimulus. Eye movements are the most commonly used dual attention stimulus, but tapping, tactile stimulation, and auditory tones are also used2. These are usually presented in an alternating bilateral fashion – e.g., first to one ear, then the other, then the first ear, etc.

It is thought that the dual attention component of EMDR facilitates information processing but, as with all forms of psychotherapy, the underlying neurobiological reason for these effects are unknown although a variety of neurobiologists have proposed mechanisms of action.3,4,5 Currently there is research support for working memory theories and the orienting response. A number of studies have indicated that the eye movement reduce emotional distress and memory vividness or enhance recall.6,7,8,9,10,11,12
