Previous research has indicated an increase in stress levels and cognitive intrusions after natural disasters. These previous studies have not, however, assessed the impact disaster induced cognitive disruption has on human performance. In the present report, we investigated the impact of the 7.1 magnitude 2010 Christchurch, New Zealand earthquake on self-reported earthquake-induced cognitive disruption and its relationship to performance on the Sustained Attention to Response Task (SART). Participants who self-reported greater cognitive disruption induced by the earthquake also had higher levels of errors of commission during SART (r=.80, p<.001). This was even the case when controlling for earthquake-induced anxiety, depression, participant sex, and self-reported sleep amount. Post-disaster assessments need to include the impact of the events directly on cognitive self-regulation and conscious thoughts, in addition to more clinical constructs, such as anxiety and depression.
先前的研究表明，自然灾害后人们的压力水平和认知干扰会增加。然而，这些先前的研究并未评估灾害引起的认知障碍对人类表现的影响。在本报告中，我们调查了 2010 年新西兰克赖斯特彻奇 7.1 级地震对自我报告的地震引起的认知障碍的影响，以及它与持续注意反应任务 (SART) 表现之间的关系。自我报告地震引起的认知障碍更大的参与者在 SART 中也有更高的错误率（r=.80，p<.001）。即使在控制了地震引起的焦虑、抑郁、参与者性别和自我报告的睡眠时间后，情况也是如此。灾后评估需要将事件对认知自我调节和有意识思维的直接影响纳入考虑范围，除了更具临床意义的焦虑和抑郁等结构。
