Dental phobic patients with reported traumatic experiences at onset of dental anxiety were compared to subjects with an indirect fear acquisition in their psychophysiological responses to video scenes showing dental procedures. It has been suggested that individuals with conditioned fear would respond with higher levels of physiological arousal in response to threat compared to subjects with indirect fear acquisition. Although the overall pattern indicates support for this hypothesis, subjects grouped on the basis of their reported fear-etiology did not statistically differ in recorded muscle tension, heart rate or skin conductance reactions to fear-provoking conditions.
将有牙科焦虑发作时报告有创伤经历的牙科恐惧症患者，与在对展示牙科手术的视频场景的心理生理反应中通过间接方式习得恐惧的受试者进行比较。有人提出，与通过间接方式习得恐惧的受试者相比，有条件性恐惧的个体在面对威胁时会以更高水平的生理唤醒做出反应。尽管总体模式表明支持这一假设，但根据报告的恐惧病因分组的受试者在记录的肌肉紧张度、心率或对引发恐惧条件的皮肤电导反应方面并无统计学差异。
