Background:Whilst data-driven processing (DDP) during trauma has been shown to play a role in poor memory integration and is associated with post-traumatic stress disorder (PTSD) re-experiencing symptoms, the pre-trauma risk factors and related cognitive mechanisms are uncertain.Aims:This experimental study aimed to investigate predictors of peri-traumatic DDP, as well as its role in attention bias to threat and free recall.Method:A virtual reality video was used to simulate an analogue trauma. Questionnaires, a free recall task, and an eye-tracking measure assessed cognitive changes after exposure.Results:Regression analysis demonstrated that trait dissociation at pre-exposure to trauma significantly predicted DDP. Attention bias towards threat-related images was found. Results showed that DDP and poorer free recall predicted attention bias to threat images and higher levels of DDP actually predicted higher overall scores in the free recall task.Conclusions:This study showed that DDP is strongly linked to dissociative traits, and along with memory disintegration it may predict attention changes after exposure to a trauma.

调查创伤诱发的数据驱动处理的预测因子及其对注意力偏差和自由回忆的影响

背景：虽然创伤期间的数据驱动处理 (DDP) 已被证明在记忆整合不良中发挥作用，并且与创伤后应激障碍 (PTSD) 重新体验症状、创伤前风险因素和相关认知机制有关是不确定的。目的：本实验研究旨在调查围创伤 DDP 的预测因素，以及它在对威胁和自由回忆的注意力偏向中的作用。方法：使用虚拟现实视频模拟模拟创伤。问卷调查、自由回忆任务和眼动追踪测量评估暴露后的认知变化。结果：回归分析表明，暴露于创伤前的特征分离显着预测 DDP。发现对威胁相关图像的注意力偏差。
