theory of emotions are formed throughout the history of psychology and physiology.It is difficult to answer the question of which one is a classic, as all true.Therefore, a more complete statement would be that they complement each other.Let us consider in detail the main provisions of each of them.
theory of emotions Wilhelm Wundt examines in more detail the structure.The scientist was able to allocate such manifestations as pleasure or displeasure, sedation or excitement.In addition, under the direction of a lot of attention has been paid or discharged voltage.In general, a psychologist singled out that the main reason for their appearance - physiological.
James-Lange theory - vasomotor model.It explains why there is this mental process.Leading role for somatovegetativnyh component.Consequently, any emotion - feelings that emerge in the process of changes in the outer movements, and involuntary (secretion, vascular and cardiac) activity.Consequently, the cause is peripheral changes.
These early theories of emotion have been criticized by physiologists in the middle of the XIX century by a series of experiments.So, Charles Sherrington transected spinal cord in the cervical region, and vagus nerves.As a result, it was shown that the animal exposure to the emotion respond as before.Therefore, the separation of the central visceral NA has no effect.
W. Cannon, an American physiologist and psychologist, has shown that at the moment of excitement going on at the same time release of the hormone adrenaline.That he can mobilize the whole body for action.At this point begins to amplify the heartbeat, there is dilation of the pupils and a violation of the digestive processes, increases the sugar.
Later came the biological theory of emotions.
One of the most popular is the concept P. Anokhin .Within its framework it is due to the appearance of positive and negative emotions that occur mismatch or match the expected result and the real state of affairs.
Within the biological theories is concept emotion activation .It is based on the role of the internal structure of the brain.Touch the stimulus comes from the periphery to the center, where it is evaluated.The fact is that laid down in the thalamus and sensory evaluation samples of any behavior.Available "response" is transmitted to the body of the implementation, which will be transmitted, how to behave: to be happy or sad, surprised or angry, and so on.
Psychological theory of emotions represented by the following.
author need-information concept is Simonov.According to her, the emotion - a reflection of the human or animal brain some actual need (in addition, important factors are the quality and value) and the probability of how it will be granted.It will be assessed on the basis of genetic or acquired before the individual experience.
In concept Schechter laid the basis for the two components that cause the experience of emotions.On the one hand, there is a physiological arousal, on the other hand, the situation begins to be interpreted cognitively.To this end, subject to interpretation appeared excited.This theory was based on a series of experiments in which respondents were injected with a stimulant drug.Then we observe the changes of behavior.
It may be noted that the modern theory of emotions explain their appearance psychophysiological causes.
