While psychophysiologic studies of posttraumatic stress disorder (PTSD) have investigated the effects of trauma-related stimuli on arousal, none have explored the development of intrusive imagery and affect states in the absence of such specific cues. The present study compares autonomic arousal during PTSD-related Rorschach responses in PTSD veterans vs. combat controls and noncombat controls. It was found that Rorshach responses containing traumatic content were found only in the PTSD group, and that these responses showed elevations in skin conductance (SC) and heart rate (HR). Our data also suggest that PTSD patients are more easily hyperaroused, especially under conditions of experienced stress and helplessness. Finally, combat control subjects exhibited lower baseline SC and HR than their counterparts, as well as decelerated HR during trauma- and stress-related Rorschach responses, suggesting a physiologic resilience in this group.
虽然创伤后应激障碍（PTSD）的心理生理学研究已经探讨了创伤相关刺激对唤醒的影响，但尚无研究在没有此类特定线索的情况下探究侵入性意象和情感状态的发展。本研究比较了PTSD退伍军人与战斗对照组和非战斗对照组在与PTSD相关的罗夏测试反应过程中的自主唤醒情况。研究发现，仅在PTSD组中发现了包含创伤内容的罗夏测试反应，并且这些反应显示皮肤电导率（SC）和心率（HR）升高。我们的数据还表明，PTSD患者更容易出现过度唤醒，尤其是在经历压力和无助的情况下。最后，战斗对照组受试者的基线SC和HR低于其他对照组，并且在与创伤和压力相关的罗夏测试反应过程中HR减速，表明该组具有生理恢复力。
