Dissociation is a psychological phenomenon, which can accompany various mental disorders. Typical symptoms last only minutes and involve depersonalization, derealization und changes of emotional experience. The symptomatalogy is furthermore characterized by a reduced sensory perception and emotional experience. In order to identify neurobiological changes in dissociation, previous research focused almost solely on reports of subjective experiences. This approach is problematic insofar, as the reports are hindered by the symptomatology itself and as there are few common operationalized constructs. Up to now, no empirical data is available which allows an objective quantification of the severity of dissociation. This is however pivotal in order to understand the neurobiological correlates of dissociation and its impact on the therapeutic process. We therefore aim to examine objective markers of depression in an experimental design. Based on the literature, the following potential markers have been identified: reduced pain perception, reduced olfactory perception, enhanced muscle tonus and cardiovascular changes. In an experimental design with symptom provocation, those parameters are examined for their usability as markers for dissociation.

解离是一种心理现象，可能伴随各种精神障碍。典型症状仅持续几分钟，涉及人格解体、现实解体和情绪体验的变化。此外，症状特征还在于感觉知觉和情绪体验降低。为了识别解离中的神经生物学变化，之前的研究几乎只关注主观体验的报告。就目前而言，这种方法是有问题的，因为报告受到症状学本身的阻碍，并且几乎没有常见的可操作结构。到目前为止，还没有可以客观量化解离严重程度的经验数据。然而，这对于理解解离的神经生物学相关性及其对治疗过程的影响至关重要。因此，我们的目标是在实验设计中检查抑郁症的客观标志。根据文献，已确定以下潜在标志：疼痛感知减少、嗅觉感知减少、肌张力增强和心血管变化。在症状激发的实验设计中，检查这些参数作为解离标记的可用性。
