James-Lange theory suggest John feeling of fear entirely independent of him noticing his physiological response.
The James-Lange theory postulates that emotional stimuli initially induce peripheral physiological fluctuations that occur without recognition of the emotion. These physical responses are further interpreted by the brain to create emotional emotional states. James-Lange's Theory of Emotion (1880s) proposed that physical changes occur first and form the basis of emotional experience. In other words, emotions are triggered by physical sensations (laughing makes you happy, running makes you scared).
According to James-Lange's theory of emotion, we only experience fear after this physiological arousal. Furthermore, different arousal patterns are associated with different emotions.
