Chapter 11 is about emotion and motivation. Six of the seven primary emotions' picture caught my attention most of all. Ekman and his colleagues researched small number of the emotions appear to be cross culturally universal, which called primary emotions. There are seven primary emotions; happiness, sadness, surprise, anger, disgust, fear, and contempt. And in the Lienfield book, there are six pictures that I can easily guess what emotion that picture describes. Even though, the people from the different cultures, it seems that our body built in the way to smile, when it comes to the happiness. No one frown when they are happy. By read this chapter, I want to know what defines and causes our primary emotions. So in the future, maybe people can be always happy in their life.
