这项研究考察了创伤相关压力源对患有（n= 35）和未患有（n= 24）创伤后应激障碍（PTSD）的退伍军人随后情绪行为的影响。自我报告和生理反应，包括声音惊吓，在基线和以下暴露于创伤相关和非创伤相关的压力源的情绪唤起的照片观看过程中记录。在基线时，两组在自我报告和生理测量中表现出相同的情绪反应模式。相比之下，创伤后应激障碍的参与者表现出一种惊吓调制模式，表明更大的防御反应和减少的视觉感知参与。这些发现，沿着在同一时间间隔内皱眉肌肌电图反应增强，表明创伤相关的再体验引发了PTSD患者随后的负面情绪反应。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
This study examined the impact of a trauma-related stressor on subsequent emotional behavior in veterans with (n= 35) and without (n= 24) posttraumatic stress disorder (PTSD). Self-report and physiological responses, including acoustic startle, were recorded during viewing of emotionally evocative photographs at baseline and following exposure to trauma-related and non-trauma-related stressors. The 2 groups exhibited equivalent patterns of emotional response across self-report and physiological measures at baseline. In contrast, following the trauma challenge, participants with PTSD showed a pattern of startle modulation suggestive of greater defensive reactivity and reduced visual perceptual engagement. These findings, along with augmented corrugator EMG reactivity during the same interval, suggest that trauma-related reexperiencing primes subsequent negative emotional responding in individuals with PTSD.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
