Main claim
William James (1884) in the US and Carl Lange (1885) in Denmark independently proposed that a stimulus first triggers bodily changes - heartbeat, muscle tension, tears - and that feeling those changes is the emotion. In James's words, we feel sorry because we cry.
Critique
Cannon (1927) objected that visceral responses are slow, that different emotions share similar bodily patterns and that emotional behaviour survives when visceral feedback is cut, and proposed the Cannon-Bard theory.
Modern evidence
The facial feedback hypothesis, Schachter and Singer's two-factor theory and Damasio's somatic marker hypothesis all keep part of the James-Lange insight that bodily states shape emotion.
