Do external motivational processes-in the form of social influences-shape people's memories for trauma? In this experiment, we examined the effects of social influence on memory and post-traumatic stress disorder (PTSD) symptomology for an analogue traumatic event. Seventy-two participants watched a distressing film; some received feedback about others' reactions to the film that either emphasised or downplayed the distressing nature of the film; control participants received no feedback. A week later, participants reported their symptoms, rated their memory on a number of characteristics and we tested their memory for the film's content. Participants who received feedback downplaying the film reported fewer PTSD-related analogue symptoms and weaker memory characteristics than their counterparts. The results suggest that people's memory phenomenology and analogue symptoms are influenced by others' feedback, but only when others' reactions downplayed the distressing nature of the film.
以社会影响形式存在的外部动机过程会塑造人们对创伤的记忆吗？在本实验中，我们研究了社会影响对模拟创伤事件的记忆及创伤后应激障碍（PTSD）症状的影响。72名参与者观看了一部令人痛苦的影片；一些人收到了关于其他人对该影片反应的反馈，这些反馈要么强调要么淡化了影片令人痛苦的性质；对照组参与者没有收到反馈。一周后，参与者报告了他们的症状，对自己记忆的多个特征进行了评分，并且我们测试了他们对影片内容的记忆。收到淡化影片反馈的参与者报告的与PTSD相关的模拟症状较少，记忆特征也比其他参与者弱。结果表明，人们的记忆现象学和模拟症状会受到他人反馈的影响，但只有当他人的反应淡化了影片令人痛苦的性质时才会如此。
