本研究探讨了情绪唤醒的心理生理学预期潜在的厌恶和高度愉快的结果。人类的大脑反应（事件相关电位）和身体反应（心率，皮肤电导，探头惊吓反射）进行了评估，沿着动机梯度确定的距离潜在的惩罚或奖励的网站。一个捕食者-猎物的生存环境被模拟使用暗示可能的金钱奖励或可能的损失的线索;线索似乎逐渐逼近观众，直到最后一步时，快速的关键反应可以确保奖励或避免惩罚性的损失。观察到的预期反应模式提高警惕和生理动员是一致的，认为情绪的生理学是建立在行动的倾向，在哺乳动物中进化，以促进生存，处理威胁或捕捉维持生命的奖励。
This research examined the psychophysiology of emotional arousal anticipatory to potentially aversive and highly pleasant outcomes. Human brain reactions (event-related potentials) and body reactions (heart rate, skin conductance, the probe startle reflex) were assessed along motivational gradients determined by apparent distance from sites of potential punishment or reward. A predator-prey survival context was simulated using cues that signaled possible money rewards or possible losses; the cues appeared to loom progressively closer to the viewer, until a final step when a rapid key response could ensure reward or avoid a punishing loss. The observed anticipatory response patterns of heightened vigilance and physiological mobilization are consistent with the view that the physiology of emotion is founded on action dispositions that evolved in mammals to facilitate survival by dealing with threats or capturing life-sustaining rewards.
