Dissociation is a disruption in the integrated functions of consciousness, memory, identity, and perception. Dissociative symptoms include derealization/depersonalization, absorption, and amnesia. These experiences can cause a loss of control over mental processes, including memory and attention. In literature, there is a paucity of research concerning the relationships between dissociation and memory performance. In this study, our aim was to investigate the relationships between dissociative experiences, attention, and memory performance in a non-clinical community sample.
In this study, we examined the relationship between dissociation and cognitive dysfunction among 60 healthy volunteers. We administered the Wechsler Memory Scale-Revised, Auditory Verbal Learning Test, Stroop Color Word Interference Test, and Dissociative Experience Scale. Here we examined the relationships between the subtypes of dissociation and memory performance as assessed by neuropsychological tests.
We found that verbal memory was negatively associated with dissociative experiences. Pathological dissociation, particularly amnesia and depersonalization/derealization, was reversely linked to general memory performance and long-term memory. Moreover, low dissociators reported higher scores on verbal memory, general memory performance, and long-term memory but lower scores on recognition than high dissociators.
The results of our study suggested that there are significant linkages between dissociative experiences and memory performance.
分离是指意识、记忆、身份和感知的整合功能受到破坏。分离症状包括现实解体/人格解体、专注和失忆。这些体验可能导致对包括记忆和注意力在内的心理过程失去控制。在文献中，关于分离与记忆表现之间关系的研究很少。在本研究中，我们的目的是调查非临床社区样本中分离体验、注意力和记忆表现之间的关系。
在本研究中，我们检查了60名健康志愿者中分离与认知功能障碍之间的关系。我们实施了韦氏记忆量表修订版、听觉词语学习测验、斯特鲁普色词干扰测验和分离体验量表。在此，我们研究了通过神经心理学测试评估的分离亚型与记忆表现之间的关系。
我们发现言语记忆与分离体验呈负相关。病理性分离，尤其是失忆和人格解体/现实解体，与总体记忆表现和长期记忆呈反向关联。此外，低分离者在言语记忆、总体记忆表现和长期记忆方面的得分高于高分离者，但在识别方面的得分低于高分离者。
我们的研究结果表明，分离体验与记忆表现之间存在显著联系。
