Sometimes a traumatic incident can trigger an enduring response of fear whenever the incident is recalled, even indirectly. A car backfiring, for instance, can set off an emotional response in a combat veteran if the loud noise becomes associated in his mind with a wartime experience.
有些時(shí)候,只要大腦中回憶起創(chuàng)傷性事件,即便是間接的回憶,也會(huì)引發(fā)人體持久的恐懼反應(yīng)。比如,汽車爆胎會(huì)讓退伍老兵產(chǎn)生情緒化的反應(yīng),只要他的腦子將這聲巨響同戰(zhàn)爭(zhēng)中的某次經(jīng)歷聯(lián)系在了一起。
