What is the difference between the James-Lang theory, and the Cannon-Bard and Schachter-Singer theories?

Answer: The Cannon-Bard theory proposes that emotions and arousal occur at the same time. The James-Lange theory proposes the emotion is the result of arousal. Schachter and Singer's two-factor model proposes that arousal and cognition combine to create emotion.

The Cannon-Brand Theory argues that we experience physiological arousal and emotion at the same time. The theory gives more attention to the role of thought or outward behavior than did James-Lang. He found that emotion occurs even if the brain was not connected to information about bodily responses, which is similar.
