From week 1 lecture, we know two types of attention : hyper attention and deep attention. Deep attention usually used by solving complex problem. But ” hyper attention excels at negotiating rapidly changing environments in which multiple foci compete for attention.” For example, I like playing computer games and when I play the computer games, I will have another things should do, such as sending messages, drinking water and so on. Because games can pause anytime. Also, I prefer to draw pictures. When I am drawing picture, no one can interrupt me and I often forget time. I really concentrate on drawing and enjoy it. I think it is deep attention.
