创伤后应激障碍（PTSD）的诊断标准之一是过度的惊吓反应；然而，这种现象并没有从经验上得到解决。作者比较了 20 名患有 PTSD 的越战退伍军人和 1-8 名没有 PTSD 的退伍军人对惊吓反应的眨眼反射肌电反应。两组中未能对惊吓刺激表现出眨眼反应的受试者被排除在进一步分析之外。在其余受试者中，13 名患有 PTSD 的受试者在中等强度的声刺激下的惊吓反应幅度明显大于 12 名对照受试者。还研究了惊吓反应性与阴性和阳性症状之间的关系。
One of the diagnostic criteria for posttraumatic stress disorder(PTSD) is an exaggerated startle response; however, this phenomenon has not been yenfled empirically. The authors compared 20 Vietnam combat veterans with PTSD and 1 8 combat veterans without PTSD on the eyeblink reflex electromyographic response of the startle reaction. Subjects in both groups who failed to show an eyeblink response to the startle stimuli were eliminated from further analyses. Among the remaining subjects, the 13 with PTSD had a significantly greater startle response amplitude than the 12 control subjects at intermediate intensities of acoustic stimuli. The relationship between startle responsivity and both negative and positive symptoms was also investigated.
