James-Lange Theory of Emotion refers to one of the early theories of emotions promoted by American Psychologist William James and Danish Psychologist Carl Lange in mid-1880's, postula ting that emotion is consciously experienced as a reaction to physical sensory experience. In other words, we feel fear because our hearts are racing; we are sad because we are crying. Although critics saw this as an overstatement, the James-Lange theory did correctly insist that sensory and cognitive experiences were intimately entwined and could not be separated from each other.

Likewsie, James-Lange Theory of Emotion is the proposition that the bodily processes of emotion come first and the mind"s perception of these bodily reactions then creates the subjective feeling of emotion.
