Cannon-Bard's theory of emotion was developed by the two physiologists Walter Cannon and Philip Bard. Walter Cannon did not agree with James-Lange's theory of emotion in several respects.
Cannon suggested that people can experience physiological reactions that are commonly linked to emotions - as the racing heart is linked to fear - without actually feeling that emotion.
He also suggested that emotional responses occur too quickly to be simply a product of physical states. Cannon first proposed his theory in the 1920s, and his work was later expanded by also physiologist Philip Bard during the 1930s.
According to Cannon and Bard's theory of emotion, we feel emotions and experience physiological reactions - such as sweating, shaking and muscle tension - at the same time.
More specifically, this theory suggests that emotions are produced when the thalamus - part of our brain that is part of emotion processing - sends a message to the brain in response to a stimulus. This results in a physiological reaction
