Using a two-wave online experiment, we investigate whether COVID-19 exposure changes participants' threat-detection threshold. Threat reactivity was measured in a signal detection task among 277 British adults who also reported how vulnerable they felt to infectious diseases. Participants' data were then matched to the local number of confirmed COVID-19 cases announced by the NHS every day. We found that participants who perceive themselves as more likely to catch infectious diseases displayed higher threat reactivity in response to increased COVID-19 cases.
通过一项两阶段的在线实验，我们研究了接触新冠病毒是否会改变参与者的威胁检测阈值。在一项信号检测任务中，对277名英国成年人的威胁反应性进行了测量，这些成年人还报告了他们感觉自己对传染病的易感性如何。然后将参与者的数据与英国国家医疗服务体系（NHS）每天公布的当地新冠确诊病例数进行匹配。我们发现，那些认为自己更有可能感染传染病的参与者，在面对不断增加的新冠病例时，表现出更高的威胁反应性。
