Darwin believed that expressions of emotion are products of evolution and compared them in different species. His theory of the evolution of emotion was composed of three main ideas: Expressions of emotion evolve from behaviors that indicate what an animal is likely to do next. If the signals provided by such behaviors benefit the animal that displays them, they will evolve in ways that enhance their communicative function, and their original function may be lost. Opposite messages are often signaled by opposite movements and postures, an idea called the principle of antithesis.
What the James-Lange theory did was to reverse the usual common-sense way of thinking about the causal relation between the experience of emotion and its expression. James and Lange argued that the autonomic activity and behavior that are triggered by the emotional event produce the feeling of emotion, not vice versa.
Cannon proposed an alternative to the James-Lange theory of emotion. The Cannon-Bard theory views emotional experience and emotional expression as parallel processes that have no direct causal relation.
With the theory of the Limbic System, Papez proposed that emotional expression is controlled by several interconnected neural structures that he referred to as the limbic system. Papez proposed that emotional states are expressed through the action of the other limbic structures on the hypothalamus and that they are experienced through the action of the limbic structures on the cortex (Pinel, J., 2009).
