Abstract

The purpose of this study was examine the influence of the structured disclosure through writing of stressful experiences on the degree of the distress and prefrontal blood flow volume. The deleterious effect of life event stress on physical and psychological functioning are well known and continue to receive wide attention(Baum and Posluszny, 1999). Unwanted thought is an automatic process, but attempts to inhabit these cognitions require working memory (WM).The more life event stress experienced , the more functional WM and inhibitory failures(Klein and Boals, 2001).The beneficial effects of emotional disclosure though expressive writing about stressful experiences have been widely reported. Current explanations focus on the cognitive changes produced by expressive writing(Pennebaker, 1997).Klein and Boals(2001) were demonstrated expressive writing improves available WM. However there were not become clear the relationship between the WM and prefrontal blood flow volume, during in structural writing disclosure for life event stress. Results of this study showed that prefrontal blood flow volume during in the structural writing disclosure condition were statistical no significance during in the stress re-experience condition. But in left hemisphere prefrontal blood flow volume in participants who decreased subjective distress was more increase during in the structural writing disclosure condition than during in the stress re-experience condition.
