Role of bilateral eye movements versus straight ahead fixation on SUDs: A lab study

Description

The purpose of the study was to examine the effects of bilateral left right saccade eye movements (BEM) versus fixation (FIX) along the median plane on the SUD related to negative autobiographic events. BEM or FIX were stimulated with visual-acoustic targets that were presented progressively further from the participant (from 20 to 150 cm) at the same speed; a laboratory device was used to provide such targets. Thirty psychology students participated in the study, half of them in the BEM condition. Eight series of BEM or FIX were run, each lasting 1 min. SUDs group mean value was initially about 4 for both groups of participants. After the BEM, the SUDs dropped to almost zero and the change was statistically significant, while after the FIX condition the change was not significant.
BEM activate alternating contralateral brain activity in central parietal and frontal ocular motor areas, while fixation along the median plane is associated with bilateral brain activation of central and posterior cortical areas (see Tzelepi Lutz, Kapoula, Experimental Brain Research, 2004).

We conclude that alternating brain activation, induced by BEM, is acting more efficiently on SUD and could be considered as one of the active principles specific to EMDR treatment. In addition observations on the originality & emotional valence of a drawing done before and after BEM or FIX (Torrance creativity test), as well as data on executive cognitive function measured with the Stroop test will be presented.
