Summary
An experiment done between Japanese and Israelis to determine if attractiveness of an design was a very important factor. In the study it was found that Japanese took attractiveness of design more of a valuable factor in design than did the Israelis that cared more about the functioning factor. A rather new study from psychology has found that affect, emotion and cognition compliment one another. The brain could be seen as three levels: Visceral, Behavioral, and Reflective. Input is taken in through the senses and as humans it is processed by the three layers to output an action. The response can be a combination of the levels (bottom-up or top-down) or it can be mostly impacted by one specific layer over ruling the others. The role of positive and negative states do have an impact on design. Happier thoughts often result in creativity; versus negative thoughts often guide people to be more contentious of the appropriate design function. Yet design can and should be driven by both thought processes in order to have both the creative and functioning factor. A brains action can be driven from both biological predisposition and experience; and it is the second and third layer that is often impacted by these factors.
Discussion
I found this to be an interesting shift between the author's last book to this one. On the "Design of Everyday Things" it was more focused on making a product that worked correctly and could be understand by users. This books takes a different approach around affect, emotion and cognition. I've seen similar work with affect and behavioral factors presented in other courses I've taken (HRI focused) so it was nice to see the correlation between fields.
