Research has shown that high trait anxiety can alter multisensory processing of threat cues (by amplifying integration of angry faces and voices); however, it remains unknown whether differences in multisensory processing play a role in the psychological response to trauma. This study examined the relationship between multisensory emotion processing and intrusive memories over seven days following exposure to an analogue trauma in a sample of 55 healthy young adults. We used an adapted version of the trauma film paradigm, where scenes showing a car accident trauma were presented using virtual reality, rather than a conventional 2D film. Multisensory processing was assessed prior to the trauma simulation using a forced choice emotion recognition paradigm with happy, sad and angry voice-only, face-only, audiovisual congruent (face and voice expressed matching emotions) and audiovisual incongruent expressions (face and voice expressed different emotions). We found that increased accuracy in recognising anger (but not happiness and sadness) in the audiovisual condition relative to the voice- and face-only conditions was associated with more intrusions following VR trauma. Despite previous results linking trait anxiety and intrusion development, no significant influence of trait anxiety on intrusion frequency was observed. Enhanced integration of threat-related information (i.e. angry faces and voices) could lead to overly threatening appraisals of stressful life events and result in greater intrusion development after trauma.

研究表明，高特质焦虑会改变对威胁线索的多感官加工（通过增强愤怒面孔和声音的整合）；然而，多感官加工的差异是否在对创伤的心理反应中起作用仍不清楚。本研究在55名健康年轻成年人的样本中，考察了在暴露于模拟创伤后七天内多感官情绪加工与侵入性记忆之间的关系。我们使用了创伤电影范式的改编版本，其中展示车祸创伤的场景是通过虚拟现实呈现的，而不是传统的二维电影。在创伤模拟之前，使用强制选择情绪识别范式评估多感官加工，该范式呈现快乐、悲伤和愤怒的仅声音、仅面孔、视听一致（面孔和声音表达匹配情绪）和视听不一致表达（面孔和声音表达不同情绪）。我们发现，与仅声音和仅面孔条件相比，在视听条件下识别愤怒（而非快乐和悲伤）的准确性提高与虚拟现实创伤后的更多侵入有关。尽管先前的结果将特质焦虑与侵入发展联系起来，但未观察到特质焦虑对侵入频率有显著影响。增强与威胁相关信息（即愤怒面孔和声音）的整合可能导致对压力生活事件的过度威胁评估，并在创伤后导致更大程度的侵入发展。
