在厌恶性皮电条件反射中，愤怒面部表情的取向是面部作为条件刺激的关键线索。实验1表明，条件反射的愤怒的面孔直接向受试者表现出显着的阻力灭绝，而条件反射的愤怒的面孔直接熄灭在灭绝过程中立即。实验2旨在研究取向因子是否仅在消光期间有效，即，方位是否是一个性能变量，或者观察到的效果是否源自采集期间的活动因素，即，如果取向主要影响学习。当方向在获得和消退阶段之间转换时，在获得过程中面部的方向并不重要;只有在消退期间，面部才需要指向受试者以唤起持续的反应。显然，受试者对愤怒的面孔获得了条件反射，而不管它的方向如何，但这种学习效果只在愤怒的面孔被指向受试者时才会保持。
The orientation of angry facial expressions is a critical cue when faces serve as conditioned stimuli during aversive electrodermal conditioning. Experiment 1 demonstrated that responses conditioned to angry faces directed toward the subjects showed significant resistance to extinction whereas responses conditioned to angry faces directed away extinguished immediately during extinction. Experiment 2 was designed to investigate whether the orientation factor was effective only during extinction, i.e., whether the orientation was a performance varialbe, or if the observed effect originated from factors active during acquisition, i.e., if the orientation primarily influenced learning. When the orientation was shifted between the acquisition and the extinction phase, it did not matter what direction the faces had during acquisition; it was only during extinction that the faces needed to be directed toward the subjects to evoke persistent responding. The subjects evidently acquired a conditioned response to the angry face regardless of its direction, but that this learning effect remained only when the angry face was directed toward the subject during extinction.
