Book Reading # 45

Reference:
Things that Makes Us Smart
Donald A. Norman
Chapter 3 & Chapter4

Summary
Chapter three talks about cognitive artifacts that have aided the human brain by making humans smarter. Norman points out that we pay much attention to people who can retain large quantities of information because these are abilities that are hard for the average person to perform. He gives an example where Socrates questions that reading did not lead to reflection, and that it was experiential. He goes on to talk about the importance of the power of representation. A very important thing he mentions is that humans perceive information as a visual representation. In the latter chapter, Norman describes the views of a cognitive artifact which are the personal point of view and the system point of view.
Discussion
I found the fourth chapter more interesting because it points out example that make you understand what Norman is getting at. The description that I liked the best is when he talks about digital versus analog displays. It would seem to me that he would discuss that the digital displays are better since in the previous chapter he mentions that humans perceive information as a visual representation.
