People show enhanced memory recall for disgust over fear, despite both being highly negative and arousing emotions. But does disgust's 'stickiness' in memory result in more false memories for disgust versus fear? Existing research finds low false-memory rates for disgust and fear, perhaps from using image lures depicting content unrelated to target images. Therefore, we presented 111 participants with disgust, fear, (and neutral) images during an attention-monitoring task.

People remember disgusting stimuli better than fearful stimuli, but do disgust's memory-enhancing effects extend to memory? This question is important because disgust reactions occur following trauma, and trauma-related involuntary memories are a hallmark of Posttraumatic Stress Disorder (PTSD) symptoms. In two experiments, we presented participants (= 88 Experiment 1; = 106 Experiment 2) with disgust, fear, and neutral images during an attention-monitoring task. Participants then completed an undemanding vigilance task, responding any time an image involuntarily came to mind.

Disgust reactions commonly occur during/following trauma and predict posttraumatic stress (PTS) symptoms. Yet, disgust is not mentioned in DSM-5 PTSD criteria. To investigate disgust's clinical significance in PTSD, we measured the relationship between disgust (and fear) reactions to a personal trauma, and problematic intrusion characteristics (e.

Purpose Of The Review: This review highlights knowledge gaps surrounding the development and use of interventions for Acute Stress Reactions (ASRs). First, we propose that a stepped care approach to intervention for ASR be developed and utilized in military operational environments. A stepped care approach would include detection and assessment, followed by behavioral intervention, and then medication intervention for ASRs.

Article Synopsis
  • The text discusses the challenges in understanding and treating trauma-related disorders due to the diverse ways individuals respond to traumatic stress.
  • The study used a predator exposure model with male Sprague-Dawley rats to explore these varied behavioral responses, utilizing tests like the elevated plus maze and acoustic startle response.
  • Four clusters of responses were identified: avoidant, moderately avoidant, and unaffected, indicating that rodent responses to trauma are similar to human responses and may help inform treatment development.
