Theory of emotions

The most common are two theories of emotions: Central and peripheral. First - the theory of cannon and Barda - links emotions with changes in the activity of certain nerve centers. Opposite her peripheral theory of James and Lange treats emotions as a consequence of developments in peripheral organs.
Contradictions of both these theories are eliminated biological theory of emotions, nominated by P. K. Anokhin. According to this theory emotions included in that link integral adaptive act, where there is a comparison of results and parameters achieved actions harvested earlier on the basis of afferent synthesis apparatus anticipation of future events (acceptor). Positive emotion arises if the signal on the results of an action performed exactly matches the parameters of acceptor of action. On the contrary, the mismatch causes negative emotion that mobilizes the body to commit new targeted action. Thus, the theory of emotions considers the role of the Central apparatus, the same information about the state of the peripheral organs.
