In this study, we explored whether individual differences in dissociation are related to certain resting electroencephalographic (EEG) parameters. Baseline EEG with eyes open and closed was recorded in an undergraduate sample (N = 67). Cortical power in the alpha range was inversely related to dissociative symptoms as measured by the Dissociative Experiences Scale, while both delta and theta power where positively related to dissociation. However, sleep experiences, as indexed with the Iowa Sleep Experiences Survey, were unrelated to resting EEG characteristics. We propose that suppression in the alpha band and raised levels of theta activity, which are typical for high dissociators, might help to explain why dissociative symptoms are accompanied by attentional and memory deficits.
在本研究中，我们探究了分离性障碍的个体差异是否与某些静息脑电图（EEG）参数相关。我们对一个本科样本（N = 67）进行了睁眼和闭眼状态下的基线脑电图记录。根据分离体验量表测量，α频段的皮质功率与分离性症状呈负相关，而δ波和θ波功率均与分离性障碍呈正相关。然而，爱荷华睡眠体验调查所显示的睡眠体验与静息脑电图特征无关。我们提出，高分离性障碍患者典型的α频段抑制和θ波活动水平升高，可能有助于解释为什么分离性症状会伴有注意力和记忆缺陷。
