The efficacy and psychobiological correlates of dual-attention task

The study being presented aimed to investigate the psycho physiological correlates and the effectiveness of different dualattention tasks used during eye movement desensitisation and reprocessing (EMDR). Sixty-two non-clinical participants with negative autobiographical memories received a single EMDR session that involved fixed or varied rate eye movements, or exposure without eye movements. Subjective units of distress and vividness of the memory were recorded at pretreatment, post-treatment, and 1 week follow-up. EMDR-with eye movements led to greater reduction in distress (SUDs) than EMDR-without eye movements. Psycho physiological measures were continuously recorded throughout each session. Heart rate decreased significantly when eye movements began; skin conductance decreased during eye movement sets; heart rate variability and respiration rate increased significantly as eye movements continued; and orienting responses were more frequent in the eye movement than no-eye movement condition at the start of exposure. These findings indicate that eye movements in EMDR are beneficial, and are coupled with distinct psycho physiological changes that may aid in the processing of negative memories. Implications for clinical practice, directions for future research, and the importance of building bridges between East & West whilst conducting EMDR research will also be discussed.
