Theories of Emotion Emotions: Definition: "A whole-organism response, involving physical arousal, expressive behaviors, and conscious experiences, is known as emotions" (David Myers, 2007). Explanation: Physiologically emotions are closely linked to arousal in the nervous system. They are a kind of complex feeling that influences our behavior through changes in the psychological and physical environment. The explanation of different events occurs through the cognitive process; an important characteristic of emotion. For example, when you feel disgust it is your response to something bad or dirty. Sociable people express their emotions more often, but those who enjoy solitude mostly hide them. Therefore emotions are also linked to the tendency of one's behavior (Schacter, Daniel L. 2011). Theories of Emotions: Origin: The different theories of emotions arose in the 3rd century BC in the times of ancient Greece and ancient China. While Western philosophical studies have labeled emotions in many different ways. According to Aristotle, to have virtue it is necessary to have emotions, as its important ingredient. As a result of several attempts, in the 19th century importance was given to emotions and studies were conducted analytically (Suchy, Yana 2011) (Aristotle). Evolutionary Theories: Charles Darwin argued in 1870 that emotions entered their lives. module because they have editing features. For example, disgust emerged because the individual, responding in different ways to this emotion, increased his survival rate. An individual's facial expressions are innate, the individual early identifies his own facial expressions to judge whether the other person is happy to meet him or not. The different theory... in the middle of the paper... the exciting fact and our sensation of the same changes as they occur is the emotion." "The nervous system of every living being is nothing more than a set of predispositions react in particular ways to contact with particular characteristics of the environment. The neural machinery is nothing more than a hyphen between certain arrangements of matter outside the body and certain impulses to inhibition or discharge within its organs.” (James, W. 1884). According to James, when you encounter any event (an approaching car), the physiological response comes automatically and you experience fear. Jesse Prinz worked on the same theory. For him too, emotions are a mental state due to messages from the body. Prinz was of the view that emotion is a simple representation of information, i.e. disgust represents hatred, fear; danger and so on (Prinz, JJ 2004) (Prinz, J. J. 2004)
