Components of Emotion
There are four basic components of emotions:
- The physiological aspect, which involves active changes in the body physically, e.g., tachycardia, tachypnoea, dilated pupils, etc.
- The cognitive component, which emphasizes the importance of thoughts, beliefs, and expectations in determining the type and intensity of emotional response.
- The behavioral component, which involves the various forms of expressions that emotions may take , e.g., facial expressions, bodily postures, gestures, and tone of voice which changes with anger, joy, fear, sorrow, etc.
- The social and cultural component, which shape subjective experience that includes elements of pleasure, or displeasure, intensity of feeling, etc. What one individual experiences as intensely as pleasurable may be boring for another.
Emotion and Brain
Emotion and Needs
This picture illustrates how the components of emotion are in action. Disgust, for example, serves three purposes:
- Avoid or vomit infected things (physiological).
- Communicate to other that the food is bad (social and cultural).
- Learn to avoid infections (cognitive).
In other words disgust serves one's interests and community interests. To do so, the brain activates vomiting reflex and facial expression reflex (behavioral).
