急性应激障碍的特征是解离反应，理论上导致创伤相关材料的编码和检索缺陷。本研究采用定向遗忘范式的列表法，对创伤后急性应激障碍（ASD; n = 14）、非ASD（n = 14）和非创伤对照组（n = 15）的提取抑制进行了研究。参与者被提供了一个混合的积极的，中性的和创伤相关的单词列表。然后给出了忘记该列表并记住第二个列表的指令，并给出了一个新的列表。ASD参与者比非ASD和对照组表现出更差的记忆被遗忘的创伤单词。ASD组也表现出对要记住和要忘记的积极词汇的识别不足。急性创伤后应激反应的严重程度与提取障碍有关。累积的研究结果表明，ASD与创伤相关和积极材料的记忆贫乏有关。
Acute stress disorder is characterized by dissociative responses that are theorized to result in deficient encoding and retrieval of trauma-related material. This study examined retrieval inhibition using the list method of the directed forgetting paradigm in traumatized individuals with acute stress disorder (ASD; n = 14), no ASD (n = 14), and a nontraumatized control group (n = 15). Participants were presented with a list of intermixed positive, neutral, and trauma-related words. Instructions to forget that list and instead remember a second list were then given, and a new list presented. ASD participants exhibited poorer recall of to-be-forgotten trauma words than the non-ASD and control groups. The ASD group also demonstrated deficient recognition of to-be-remembered and to-be-forgotten positive words. Severity of acute posttraumatic stress response was associated with retrieval impairments. The cumulative findings suggest that ASD is associated with impoverished memory for trauma-related and positive material.
