创伤后记忆入侵的发生与创伤前后的分离有关。在本研究中，我们试图通过实验诱导分离，并研究其对侵入性记忆的影响。共有39名大学生被随机分配到标准条件下或在双重任务的条件下，他们同时执行敲击任务观看压力电影。他们评估了电影后的痛苦，并在两周后再次评估，并记录了侵入性记忆的日记。与预测相反，两种情况下的痛苦或外显记忆水平没有差异，双任务条件下，其次是显着较少的记忆入侵。双重任务条件可能无法提供一个很好的模拟自然发生的解离。根据创伤后应激障碍的双重表征理论，讨论了敲击任务可能的预防作用。
The occurrence of memory intrusions after a trauma has been linked to peri-traumatic dissociation. In this study, we attempted to induce dissociation experimentally and investigate the impact on intrusive memories. A total of 39 undergraduates were randomly assigned to watch a stressful film under standard conditions or under a dual-task condition in which they simultaneously performed a tapping task. They rated their distress post-film and again after 2 weeks, and kept a diary of intrusive memories. Contrary to prediction, there were no differences in levels of distress or explicit memory between the two conditions, and the dual-task condition was followed by significantly fewer memory intrusions. Dual-task conditions may not provide a good analogue to naturally occurring dissociation. The possible preventive effects of the tapping task are discussed in terms of the dual-representation theory of post-traumatic stress disorder.
