In the course of evolution, human developed rich emotional system. From evolutionary point, emotions are agents of change and reaction. It also serves to maintain social bonds.

Psychologists think that humans are equipped with set of predictable responses to certain situations. These are called basic emotions: anger, fear, surprise, disgust, joy and sadness.

James-Lange theory of emotion suggest that emotions occur as a result of physiological reactions to events. When one sees external stimulus that leads to physiological reaction, emotion reaction is dependent upon hos one interpret those physical reactions. So, this theory states that one will interpret one’s physical reactions and conclude their emotion.
Canon-Bard theory of emotion suggest that one feel emotions and experience physiological reactions simultaneously. Emotions result when thalamus sends a message to the brain in response to stimulus, resulting in physiological reaction.
Schachter-Singer theory is also known as two-factor theory of emotion which is an example of cognitive theory of emotion. It suggests that physiological arousal occurs first and one must identify the reason behind this arousal in order to experience and label it as an emotion.

Being self-conscious, it makes human increasingly invested and crafty in needs for survival. Human also developed more complex rational system where they imagine past and future selves to reason about old and future.
