对自然发生的声音的情绪反应（例如，尖叫、色情、炸弹等）在两项研究中进行了调查。在实验1中，受试者评价的快乐和唤醒时，每听60个声音，其次是一个偶然的自由回忆任务。由每个secund的平均评分定义的二维情感空间的形状与以前获得的图片相似，并且，像图片记忆一样，自由回忆对于情绪唤起刺激最高。在实验2中，自主神经和面部肌电图（EMG）活动记录，而一组新的受试者听相同的一组声音，惊吓反射使用视觉探头测量。与听悦耳的声音相比，听不愉快的声音会导致更大的惊吓反射，更多的皱眉肌EMG活动和更大的心率减速。皮肤电反应较大的情绪唤起比中性材料。综上所述，这些数据表明，听觉线索以类似于图片的方式激活了情绪表达背后的食欲和防御动机回路。
Emotional reactions to naturally occurring sounds (e.g., screams, erotica, bombs, etc.) were investigated in two studies. In Experiment 1, subjects rated the pleasure and arousal elicited when listening to each of 60 sounds, followed by an incidental free recall task. The shape of the two-dimensional affective space defined by the mean ratings for each secund was similar to that previously obtained for pictures, and, like memory for pictures, free recall was highest for emotionally arousing stimuli. In Experiment 2, autonomic and facial electromyographic (EMG) activity were recorded while a new group of subjects listened to the same set of sounds; the startle reflex was measured using visual probes. Listening to unpleasant sounds resulted in larger startle reflexes, more corrugator EMG activity, and larger heart rate deceleration compared with listening to pleasant sounds. Electrodermal reactions were larger for emotionally arousing than for neutral materials. Taken together, the data suggest that acoustic cues activate the appetitive and defensive motivational circuits underlying emotional expression in ways similar to pictures.
