Answer:
James–Lange theory
Explanation:
The theory of James – Lange is an assumption about the descent and essence of emotions and is one of the oldest theories of emotion in modern psychology.
The theory's basic principle is that the emotional experience is instigated by physiological excitement.
Rather than feeling an emotion and subsequent physiological response, the theory suggests that the behavioral switch is primary, and then emotion is endured once the brain responds to the information obtained through the nervous system of the body.
