What is an emotion?
An emotion is a mental and physiological state that arises when you experience something that is emotionally significant, such as pleasure, pain, anger, fear, or sadness. Emotions are often accompanied by feeling states, such as happiness, sadness, envy, love, hatred, etc., and behavioral responses, such as smiling or crying.
Emotions are important for motivating adaptive behaviors. For example, the unpleasant emotion of fear can motivate you to take action to avoid danger. The pleasant emotions of love and joy may motivate you to seek out social interactions and procreate.
