Which theory would be considered plausible by evidence that different emotional states have real physiological differences?

James Lange theory would be considered plausible by evidence that different emotional states have real physiological differences. The theory states that are two steps that must be completed before a person experiences a emotion. First, the person must experience an event which will cause physiological reaction. The person must then interpret the reaction to feel emotion. Emotions can be different based on the physiological reaction.
