Levi drinks three cups of coffee. then, as he walks to his first job interview, he feels his heart racing. levi believes this is due to the caffeine in the coffee, and stays relatively calm as he begins the interview. levi's lack of nervousness can be explained best by theory of emotion.

The answer is the Schachter-Singer theory.

Explanation:

This theory explains that a physiological response is identified and labeled by the person, who then experiences an emotion. For example, increased blood pressure and sweating may be either caused by excitement or fear, so the person must identify how he feels based on the context.

In the example, Levi attributes his increased heart rate to caffeine (instead of stress or nervousness), so he stays calm.
