早期的研究表明，受试者暴露于不同的面部表情自发地反应不同的面部肌电图（EMG）反应模式。在本研究中，受试者暴露于与恐惧相关（蛇/蜘蛛）和与恐惧无关（花/蘑菇）的刺激，同时测量面部EMG活动、皮肤电导反应（SRR）和心率（HR）。刺激诱发不同的反应模式。恐惧相关的刺激引起增加的皱眉肌活动，而恐惧无关的刺激引起增加的肌肉活动。恐惧相关的刺激也诱发HR减速和更大的SCR幅度。目前的数据是一致的理论，面部构成了一个情绪的“读出/输出系统”。
Earlier research has shown that subjects exposed to different facial expressions react spontaneously with different facial electromyographic (EMG) response patterns. In the present study subjects were exposed to fear-relevant (snakes/spiders) and fear-irrelevant (flowers/mushrooms) stimuli, while facial EMG activity, skin conductance responses (SRRs) and heart rate (HR) were measured. The stimul evoked different response patterns. Fear-relevant stimuli elicited increased corrugator muscle activity, whereas fear-irrevelant stimuli evoked increased zygomatic muscle activity. Fear-relevant stimuli also evoked HR deceleration and larger SCR magnitudes. The present data are consistent with the theory that the face constitutes an emotional "readout/output-system".
