Twenty male subjects (Ss) were repeatedly confronted for five seconds to pictures with positive, negative and neutral valence. During the picture presentation facial EMG-reactions of five mimic muscles (m. frontalis lateralis, m. corrugator supercilii, m. orbicularis oculi, m. zygomaticus major on the right and left side of the face) were recorded. In addition, heart rate was measured. It could be shown that during repeated presentation of pictures with positive valence the m. orbicularis oculi and the m. zygomaticus major on both sides of the face yielded enhanced average EMG-reactions as compared to the repeated presentation of pictures with negative and neutral valence. During presentation of pictures with negative valence the m. frontalis lateralis and the m. corrugator supercilii revealed enhanced EMG-reactions as compared to the repeated presentation of pictures with positive valence. Furthermore, it could be shown that during the repeated presentation of pictures with positive valence those facial muscles which mainly react during confrontation with pictures of positive valence showed a continuous decrease of EMG-activity. Facial muscles which mainly react during the presentation of pictures with negative valence do not show a continuous decrease in EMG-activity during the course of the repeated presentation of pictures with negative valence. Additionally, the EMG-activity of the m. zygomaticus major on the right and lift side of the face do not differ with respect to the mean activity and the time course during confrontation of pictures with positive valence. The m. orbicularis oculi yielded enhanced EMG-reactions during the presentation of pictures with positive valence as compared to both m. zygomaticus major muscles. The present results are discussed with respect to psychobiological theories concerning facial expression.
20名男性受试者（Ss）被反复面对带有正性、负性和中性效价的图片5秒钟。在图片呈现过程中，记录了面部五块表情肌（双侧的颞肌外侧肌、皱眉肌、眼轮匝肌、颧大肌）的肌电图反应。此外，还测量了心率。结果表明，与反复呈现负性和中性效价的图片相比，在反复呈现正性效价的图片时，双侧的眼轮匝肌和颧大肌产生了增强的平均肌电图反应。与反复呈现正性效价的图片相比，在呈现负性效价的图片时，颞肌外侧肌和皱眉肌显示出增强的肌电图反应。此外，还可以表明，在反复呈现正性效价的图片过程中，那些在面对正性效价图片时主要产生反应的面部肌肉的肌电图活动持续下降。在反复呈现负性效价的图片过程中，那些在呈现负性效价图片时主要产生反应的面部肌肉的肌电图活动并没有持续下降。此外，在面对正性效价的图片时，面部右侧和左侧的颧大肌的肌电图活动在平均活动和时间进程方面没有差异。与双侧颧大肌相比，在呈现正性效价的图片时，眼轮匝肌产生了增强的肌电图反应。本文根据有关面部表情的心理生物学理论对研究结果进行了讨论。
