The surrounding environment easily influences me, so I try to find the reason why some of us always affect it. In the book, it is clear that emotion bases on personal experience. People understand the feeling of emotion, just because people experience it every day. When someone mentions a kind of emotion, the others will feel the same sense of it directly, like upset, depress, happiness. However, why people will produce emotion? Which kind of condition will affect emotion? Emotions involve some perceptual experience –they are responses to what we see and hear, smell, and touch; they include some evaluation or appraisal. That is why most artists can create a successful atmosphere to invite audiences to interact. It gives me some ideas to consider the emotional engagement of audiences. All of us experience weather, we know the sense of weather, but we cannot describe it clearly, it is an abstraction. I think if I give a feeling of weather, it will be better than providing an object of describing the weather. And this book also mentions that emotion will affect two opposites. For example, if someone feels strong cold sensing in winter when spring coming, he will feel warm. It seems like people go through some contrastive things that will easy to produce sense. The emotion is a kind of body reflection. How to connect the body of a human to my art practice? What type of atmosphere will improve emotional engagement? How to relate weather to emotion? I find two crucial ways. Firstly, I need to combine some experiences of the ordinary with practice; the other one is that I need to express two opposites to improve the sensing of the audience.
