Answer:The two-factor theory of emotion.
Step-by-step explanation:
Based on this theory our emotions are made of two elements which is we get physcally aroused and we cognitively label that arousal.
So physical arousal must be accompanied by labeling it in order to assign certain emotions to it.
For example if we are walking alone in a stranded road at night and someone walks towards us, first thing is I am seeing a stranger and he is approaching me, my heart beats faster and I'm shaking. This all physiological arousal and the question next is why I am shaking and to label this I will conclude that I fear this man I'm frightened that why I'm shaking
