Plutchik developed “Wheel of Emotion” by placing emotions according to some criteria. As shown in figure 3.2, the neighboring emotions are similar while those at the opposite ends are opposite emotions; for instance anticipation surprise, joy-sadness etc. In addition, it is possible to have different emotions by combining different emotions in the “Wheel of Emotion”. To illustrate,

• joy and anticipation = optimism
• acceptance and fear = submission
• surprise and sadness = disproval
• anger and disgust = contempt
• joy and acceptance = love
• anticipation and anger = aggressiveness
• fear and surprise = Awe (dread ?*)
• disgust and sadness = remorse
