Abstract
Traumatic memory intrusions, the involuntary retrieval of unwanted memories, significantly impact mental health. The dual representation theory proposes that the origin of intrusion lies in the overactivated sensory memory not being integrated with the corresponding contextual memory, highlighting the crucial associations between memory contextualization and intrusion. To test this, our study investigated whether enhancing memory contextualization could effectively reduce intrusion. After experiencing analogue trauma with the trauma film paradigm, 96 healthy participants were randomly allocated to three intervention groups: active contextualization (AC) in which participants actively retrieve and restructure film content, passive contextualization (PC) in which participants passively restudy content-matched pre-contextualized information, and working memory taxation (WM) in which participants performed a working memory dual-task. Diary recordings over the subsequent week revealed a significant reduction in intrusion frequency in the AC group compared to both the PC group and a no-intervention control group. Furthermore, comparing AC with WM, a well-established laboratory intervention on intrusion, established a superior efficacy of the AC intervention in reducing intrusions. Finally, analyses of the explicitly recollected film memories identified the critical element of active contextualization to be memory integration induced by active memory retrieval. Together, our findings suggest that active contextualization causally diminishes intrusions, providing novel insights into the regulation of the contextual memory system in intrusion intervention.
创伤性记忆入侵,即非自愿地检索不想要的记忆,对心理健康有重大影响。双重表征理论认为,入侵的根源在于过度激活的感官记忆没有与相应的情境记忆整合在一起,这凸显了记忆情境化与入侵之间的重要关联。为了验证这一点,我们的研究调查了增强记忆情境化是否能有效减少入侵。96名健康参与者在经历了创伤电影范式的模拟创伤后,被随机分配到三个干预组:主动情境化(AC)组,参与者主动检索和重组电影内容;被动情境化(PC)组,参与者被动地重新学习内容匹配的预情境化信息;工作记忆征税(WM)组,参与者执行工作记忆双重任务。随后一周的日记记录显示,与 PC 组和未干预对照组相比,AC 组的入侵频率明显降低。此外,将 AC 与 WM(一种成熟的实验室入侵干预方法)进行比较后发现,AC 干预方法在减少入侵方面具有更优越的效果。最后,对明确回忆起的电影记忆进行分析后发现,主动情境化的关键因素是主动记忆检索所引起的记忆整合。总之,我们的研究结果表明,主动情境化会因果性地减少闯入,为情境记忆系统在闯入干预中的调节提供了新的见解。
期刊介绍:
The major focus of Behaviour Research and Therapy is an experimental psychopathology approach to understanding emotional and behavioral disorders and their prevention and treatment, using cognitive, behavioral, and psychophysiological (including neural) methods and models. This includes laboratory-based experimental studies with healthy, at risk and subclinical individuals that inform clinical application as well as studies with clinically severe samples. The following types of submissions are encouraged: theoretical reviews of mechanisms that contribute to psychopathology and that offer new treatment targets; tests of novel, mechanistically focused psychological interventions, especially ones that include theory-driven or experimentally-derived predictors, moderators and mediators; and innovations in dissemination and implementation of evidence-based practices into clinical practice in psychology and associated fields, especially those that target underlying mechanisms or focus on novel approaches to treatment delivery. In addition to traditional psychological disorders, the scope of the journal includes behavioural medicine (e.g., chronic pain). The journal will not consider manuscripts dealing primarily with measurement, psychometric analyses, and personality assessment.
