Description

The purpose of this study was to examine the hypothesis that individuals who experienced trauma had less working memory (WM) capacity than individuals who did not. The participants consisting of undergraduates filled out the Traumatic Experiences Schedule and the Impact of Event Scale (IES) that measured posttraumatic stress reactions. The participants were divided into two groups, those who have trauma (n=18) and not trauma (n=19). The capacity of WM was measured by the operation span task (OSPAN) for each group. It was found that the OSPAN score of the group with trauma was lower than that without trauma. The result suggested that the existence of trauma is related to WM capacity. Based on this result, it was discussed that the possibility of intervention in trauma to increase WM.
