Abstract

ABSTRACTPersistent negative emotions are a key post-traumatic stress (PTS) symptom. Disgust occurs during/following traumatic events and predicts PTS symptoms, but is overlooked relative to other negative emotions like fear. Here, we investigate how trauma-related disgust fades-or persists-in memory (i.e., a person's recollection of how they felt during a traumatic event vs. their current feelings), and over time, relative to fear. In a cross-sectional (Study 1; N = 471) and longitudinal (Study 2; N = 160) study, participants rated their disgust and fear reactions to a recent stressful/traumatic event, at the time the event occurred (peritraumatic; "then") and at present (posttraumatic; "now"). Study 2 participants provided additional "now" emotion ratings 3 months later. Cross-sectional comparisons showed that whilst participants' disgust and fear reactions were lower in intensity "now" relative to "then", fear faded to a greater degree than disgust. Time since the traumatic event and PTS symptom severity were not related to disgust's relative persistence. In contrast, disgust and fear similarly persisted longitudinally. We conclude disgust and fear similarly persist over time, but disgust persists in memory more than fear. Understanding how to reduce feelings of disgust following trauma is clinically important, since disgust is more resistant to PTSD treatments than fear.

非临床人群对个人创伤的厌恶和恐惧反应的不同消退。
摘要持续性负性情绪是创伤后应激(PTS)的主要症状之一。厌恶发生在创伤事件期间/之后,预示着PTS症状,但相对于其他负面情绪,如恐惧,它被忽视了。在这里,我们调查了与创伤相关的厌恶是如何在记忆中消失或持续存在的(即,一个人对创伤事件时的感受与他们当前的感受的回忆),以及随着时间的推移,相对于恐惧。在横断面(研究1;N = 471)和纵向(研究2;N = 160)的研究中,参与者评估了他们对最近的压力/创伤事件的厌恶和恐惧反应,在事件发生的时候(创伤周围;“当时”)和现在(创伤后;“现在”)。研究2的参与者在3个月后提供了额外的“现在”情绪评分。横断面比较显示,虽然参与者的厌恶和恐惧反应在“现在”相对于“当时”的强度较低,但恐惧比厌恶减弱的程度更大。创伤事件发生的时间和PTS症状的严重程度与厌恶的相对持久性无关。相反,厌恶和恐惧同样会纵向持续。我们得出结论,厌恶和恐惧同样会随着时间的推移而持续,但厌恶比恐惧更能在记忆中持续。了解如何减少创伤后的厌恶感在临床上很重要,因为厌恶比恐惧对创伤后应激障碍治疗更有抵抗力。

期刊介绍: Memory publishes high quality papers in all areas of memory research. This includes experimental studies of memory (including laboratory-based research, everyday memory studies, and applied memory research), developmental, educational, neuropsychological, clinical and social research on memory. By representing all significant areas of memory research, the journal cuts across the traditional distinctions of psychological research. Memory therefore provides a unique venue for memory researchers to communicate their findings and ideas both to peers within their own research tradition in the study of memory, and also to the wider range of research communities with direct interest in human memory.
