For providing explanation about emotion , psychologist has propagated a number of theories. A few important ones are illustrated as follow:
This theory was firstly introduced by William James and later in 1885, a Danish psychologist Carl Lang had brought some conclusion on James and consequently, the theory is known as James-lang theory.
This theory states, the perception of the stimulus caused by our body to undergo certain physical change and we experience emotion. In this theory stimulus bring physiological changes and causes emotional experience. For instance; when we see a tiger, we run away, because we feel afraid. Thus it is concluded from this theory the emotion spring from physiological change.
Stimulus (tiger) > Physiological change (we run) > Emotional experience (we feel afraid)
In 1927 American psychologist Walter Canon unleashed an attack against James-lang theory, and later on reinforced by L.L. Bard and consequently named this theory as Canon-bard Theory
This theory states both physiological arrousal and an emotional experience are produced simultaneously by same nerve stimulus. For instance;when we see a dog we run and at the same time we feel afraid.
Here, we perceive stimulus(dog), the sensory impulses reach the Thalamic-hypothalamic region. From there they are carried simultaneously to the internal organ of the body Cerebral cortex. The cerebral cortex receives and experience emotion, at the same time the physical change are occuring in our body, where Autonomic Nervous System gives response.
Thus when we encounter a frightening stimulus(dog), the sequence of the arrousal of emotion take the form we perceive the dog we run and at the same time we afraid, we neither have emotional response and emotional experience preceding the other.
During 1970, the American psychologist Stanley Schachter & Jorome Singer adopted an electric approach to both the earlier theorist of emotion and introduced a new theory called cognitive theory of emition
This theory suggested that our physical arrousal together with our perception and judgement of situation jointly determine the emotion we feel. In other words our emotional arrousal depend on the physiological change and the mental interpretation of those changes. Here, the dominant cognitive element of our behavior in the form f our previous knowledge and our interpretation of the present situation directly affect our emotional experience.
