创伤受害者的自传体记忆通常被描述为在两个方面受到干扰。首先，创伤经常以非自愿的、侵入性的回忆的形式被重新体验。第二，创伤很难主动（策略性）回忆起来;重要的部分可能完全或部分无法接近，这一特征被称为分离性遗忘。这些特征经常被PTSD研究人员提及，并被DSM-IV-TR列为PTSD症状。相反，我们发现，无论是非自愿和自愿的回忆，增强了编码过程中的情绪压力。我们还表明，诊断中的创伤后应激障碍症状解决分离性遗忘症，难以记住创伤的重要方面与其余的创伤后应激障碍症状的相关性较低，而不是难以忘记创伤的重要方面的概念逆转。我们的发现与过去40年来塑造PTSD研究的关键假设相矛盾。
Autobiographical memories of trauma victims are often described as disturbed in two ways. First, the trauma is frequently re-experienced in the form of involuntary, intrusive recollections. Second, the trauma is difficult to recall voluntarily (strategically); important parts may be totally or partially inaccessible—a feature known as dissociative amnesia. These characteristics are often mentioned by PTSD researchers and are included as PTSD symptoms in the DSM-IV-TR. In contrast, we show that both involuntary and voluntary recall are enhanced by emotional stress during encoding. We also show that the PTSD symptom in the diagnosis addressing dissociative amnesia, trouble remembering important aspects of the trauma is less well correlated with the remaining PTSD symptoms than the conceptual reversal of having trouble forgetting important aspects of the trauma. Our findings contradict key assumptions that have shaped PTSD research over the last 40 years.
