Intrusive memories are those that spring to mind unbidden, e.g. sensory recollections of stressful/traumatic events. We review recent methods to monitor intrusions of a stressor (a trauma film) within the laboratory.
Recent studies suggest three main methodologies after viewing a trauma film by which to monitor intrusions in the laboratory: during post-film rest periods, after exposure to trigger cues, and while performing an ongoing task. These approaches allow factors to be tested (e.g. psychological or pharmacological) that may influence the frequency of occurrence of intrusions.
We raise methodological considerations to guide trauma film studies using intrusion monitoring in the laboratory to complement monitoring approaches in daily life (e.g. diaries). Intrusion monitoring in the laboratory also confers greater experimental control and may open novel research avenues, to advance intervention development to mitigate problematic intrusive memory symptoms.
侵入性记忆是指那些不由自主地涌上心头的记忆，例如对压力/创伤事件的感官回忆。我们回顾了近期在实验室中监测应激源（一部创伤影片）侵入情况的方法。
近期研究表明，观看创伤影片后，在实验室中监测侵入情况主要有三种方法：在影片播放后的休息期间、接触触发线索后以及执行正在进行的任务时。这些方法可以测试可能影响侵入发生频率的因素（如心理或药理学因素）。
我们提出了一些方法学上的考量，以指导在实验室中使用侵入性监测的创伤影片研究，从而补充日常生活中的监测方法（如日记）。实验室中的侵入性监测还能提供更大的实验控制，并可能开辟新的研究途径，以推动干预措施的发展，减轻有问题的侵入性记忆症状。
