Potentially traumatic events elicit intrusive memories to which some individuals are more vulnerable than others. Lower abstract reasoning capacity has been related to more intrusive memories. A more perceptual processing style when encoding the event may mediate this link. Another potential mechanism is lower attentional control, resulting in greater attentional bias toward trauma-related content. We examined both of these possibilities using a trauma-analogue paradigm. One hundred and twenty participants completed abstract reasoning tasks. Then, 90 participants watched a negative video, and 30 participants watched a neutral video. The level of perceptual processing (P1) and attentional bias (RT) towards trauma-related stimuli were measured with a pictorial Stroop task while recording EEG. Intrusive memories were recorded for 5 days. Abstract reasoning was not associated with intrusive memories. However, lower abstract reasoning tended to be associated with more perceptual processing (greater P1 amplitude) following the negative video. More perceptual processing also tended to be related to more intrusive memories for younger participants. A more pronounced attentional bias was related to more intrusive memories, but only for women. Unexpectedly, also for women, better verbal reasoning was linked to a more pronounced attentional bias. Results are compared to existing studies and future implications are discussed.

潜在的创伤性事件会引发侵入性记忆，而某些人比其他人更容易受到这种影响。较低的抽象推理能力与更多的侵入性记忆有关。对事件进行编码时更感性的处理方式可能会调解此链接。另一个潜在的机制是注意力控制较低，导致对创伤相关内容的注意力更加偏向。我们使用创伤模拟范式检查了这两种可能性。一百二十名参与者完成了抽象推理任务。然后，90 名参与者观看了负面视频，30 名参与者观看了中性视频。在记录脑电图的同时，通过图画斯特鲁普任务测量对创伤相关刺激的知觉处理水平（P1）和注意力偏差（RT）。侵入性记忆被记录了5天。抽象推理与侵入性记忆无关。然而，较低的抽象推理往往与负面视频后更多的感知处理（更大的 P1 幅度）相关。对于年轻参与者来说，更多的感知处理也往往与更多的侵入性记忆有关。更明显的注意力偏差与更多的侵入性记忆有关，但仅限于女性。出乎意料的是，对于女性来说，更好的言语推理也与更明显的注意力偏差有关。将结果与现有研究进行比较并讨论未来的影响。
