Emotions are divided into categories because they are discrete from one another. Each emotion entails a separate and distinct set of reactions, consequences, and expressions. The feeling and expression of emotions is a natural occurrence, and, it is actually a universal occurrence for some emotions. There are six basic emotions that are considered universal to the human species across age, gender, race, country, and culture and that are considered to be categorically distinct. These six basic emotions are: happiness, disgust, sadness, surprise, anger, and fear. According to the discrete emotions approach, people experience one emotion and not others, rather than a blend. Categorical perception of emotional facial expressions does not require lexical categories. Of these six emotions, happiness is the most easily identified.
