本研究的目的是评估是否厌恶条件反应的面部刺激是可检测的情绪反应系统的所有三个组成部分，即表达/行为，生理/自主和认知/经验的组成部分的情绪。两组受试者的条件反射愤怒或高兴的面部表情刺激使用100分贝的噪音作为UCS的差分厌恶条件反射范例。情绪反应系统的三个组成部分被测量为：（1）面部肌电图反应（皱眉肌和肱二头肌区域）;（2）自主活动（皮肤电导，SCR; SCR半恢复时间，T/2;心率，HR）;和（3）体验情绪的评级。结果发现，在愤怒组中，情绪反应系统的所有组成部分都可以检测到更大的EMG和对灭绝的自主抵抗力以及更大的自我报告的恐惧。更具体地说，愤怒组的面部肌电图皱眉肌，伴随着SCR频率，较慢的SCR恢复，阻力条件反射在HR和更高的自我报告的恐惧比快乐组的阻力条件反射的阻力调节效果。因此，对愤怒的面部刺激的厌恶性条件反射诱导了一种统一的负面情绪反应模式，正如情绪反应系统的所有三个组成部分所示。这些数据表明，一个负面的“情感程序”会引发不同情绪成分的反应。结果表明，人类受试者在生理上准备好对愤怒的面部刺激做出负面情绪反应。
The present study was designed to evaluate whether aversively conditioned responses to facial stimuli are detectable in all three components of the emotional response system, i.e. the expressive/behavioral, the physiological/autonomic and the cognitive/experienced component of emotion. Two groups of subjects were conditioned to angry or happy facial expression stimuli using a 100 dB noise as UCS in a differential aversive conditioning paradigm. The three components of the emotional response system were measured as: (1) Facial-EMG reactions (corrugator and zygomatic muscle regions); (2) autonomic activity (skin conductance, SCR; SCR half recovery time, T/2; heart rate, HR); and (3) ratings of experienced emotion. It was found that responses in all components of the emotional response system were detectable in the angry group as greater EMG and autonomic resistance to extinction and greater self-reported fear. More specifically the angry group showed a resistant conditioning effect for the facial-EMG corrugator muscle that was accompanied by resistant conditioning for SCR frequency, slower SCR recovery, resistant conditioning in HR and a higher self-reported fear than the happy group. Thus, aversive conditioning to angry facial stimuli induce a uniform negative emotional response pattern as indicated by all three components of the emotional response system. These data suggest that a negative ''affect program'' triggers responses in the different emotional components. The results suggest that human subjects are biologically prepared to react with a negative emotion to angry facial stimuli.
