From the book Emotional Design, In chapter one Donald A. Norman are story about visceral, behavioral, and reflective are the three very different dimension are interwoven through any design. Donald say it is not possible to have design without visceral, behavioral, and reflective. but more important, note how these three components interweave both emotions and cognition. other than that, emotion play an important when we want make a choosing. whereas emotion is said to be hot, animalistic, and irrational, cognition is cool, human, and logical. this contrast comes from along intellectual tradition that prides itself on rational, logical reasoning. emotions are out of place in a polite, sophisticated society. they are remnants of our animal origins, but we humans must learn to rise above them. At least, that is the perceived wisdom. Along with emotions, there is one other point as well. Aesthetics, attractiveness, and beauty. when Donald A. Norman wrote The Design of Everyday Things, Donald intention was not to denigrate aesthetics or emotion. Donald simply wanted to elevate usability to its proper place in the design world, alongside beauty and function. Donald thought that the topic of aesthetics was well covered elsewhere, so he neglected it. The result has been the well deserved criticism from designers: ''if we were to follow Norman's prescription, our design would be useable-but they would also be ugly.'' Donald has just started a research project examining the interaction of affect, behavior, and cognition..And most of the research focused upon negative emotions such as stress, fear, anxiety, and anger. Moreover, emotions play a critical role in daily lives, helping asses situation as good or bad,safe or dangerous. Positive emotions are as important as negative ones. Positive emotions are critical to learning, curiosity, and creative thought, and today research is turning toward this dimension.
In chapter two, Donald explain about Multiple Faces of Emotion and Design. In this chapter shows about several levels of cognitive and emotional system-visceral, behavioral, and reflective at work. That visceral response is immediate and positive, triggering the reflective system to think about the past. The behavioral level is about use experience with a product . But experience itself has many faces. Function, performance, and usability. The ways in which the three level interact are complex. Still, for purposes of application, it is possible to make some very useful simplication. Even these simplication are difficult to apply. Should some products be primarily visceral in appeal. Other behavioral, reflective and requirements at one level against those of the others? The designer must know the audio for whom the product is intended. Although Donald have described the three level separately, any real experience involves all three. A single level is hard to practice at once, and if it being practises at all is most likely to come from the reflective level than from the behavioral or the visceral. The three levels of processing lead to three corresponding forms of design. Visceral, behavioral, and reflective. Each plays a critical role in human behavior, each an equally critical role in the design, marketing and use of products. some brands are simply informative ,essentially name a company or it's product. But on the whole, the brand name is a symbol that represents one entire experience with a product and the company that produces it. Some brand represent quality and high prices. Some represent a focus upon prices, value upon service, value for money, and some brands stand for shoddy products. And of course most brand names are meaningless, carrying no emotional power at all. Barands are all about emotion. And emotion are all about judgement. Brands are signifiers or our emotionanal responses, which is why they are so important in the world of commercial.
At chapter three, Donald are talk about Three Levels of Design: Visceral, Behavioral, and Reflective. Visceral design is what nature does. We humans evolved to coexist in the environment of other humans, animals, plants, landscapes, weather, and other natural phenomena. As a results, we are exquisitely tuned to receive powerful emotional signals from the environment that get interpreted automatically at the visceral level. When we perceive something as beauty, that judgement comes directly from the visceral level. In the world of design, beauty is generally frowned upon, denounced as pretty, or lacking depth and substance. But that is designer's reflective level speaking because designers want their collageous to recognize as imaginatives, creative, and deep, making some pretty or cute or fun is not well accepted. But there is a place in our lives for such things, even if they are simple. we can find visceral design in advertising, folk art and crafts, and children's items. Effective visceral design requires the skill of the visual and graphic artist and the industrial engineer. Shape and form matter. The physical feel and texture of the materials matter. Visceral design is all about immediate emotianal impact. It has to feel good, look good. Sensuality and sexuality play roles. This is a major roles of point of presence displays in stores, in brochures, in advertisements, and in other anticements that emphasize appearance. Similarly, otherwise highly rated products may be turned down if they do not appeal to the aesthetic sense of the potential buyer. The meaning of behavioral is about use. Appearance does not really matter. The principles of good behavioral design are well known and often told. Good behavioral design has to be a fundamental part of the design process from the start. behavioral design begins with understandings the user's need. Different with reflective design , reflective design covers a lot territory. It is all about message, about culture, and about the meaning of a product or it's use. In fact, even people who claim a complete lack of interest in how they are perceived.
