    Today, in the developing field of cognitive science, two different views are emerging. The traditional view considers thought to be ratio- nal, logical, and orderly; this approach uses mathematical logic as the scientific means to explain thought. Adherents of this approach have pioneered the development of schemas as the mechanism of human memory. A newer approach is rooted in the working of the ...

    Design Psychology **1. Human thought: Mostly Subconscious** Because we are only aware of the reflective level of conscious processing, we tend to believe that all human thought is conscious. But it isn't. We also tend to believe that thought can be separated from emotion. This is als false. **Cognition and Emotion ** Cognitive thoughts lead to emotions: emotions drive cognitive thoughts. The ...

    affordance limitation mappings 产品的功能必须不言自明,例如一把剪刀的hole就是表明了他的使用方法——用手指穿过孔(affordance,功能可见性?),孔的大小就是 limitation,孔大能穿过更多的手指

    As you might imagine, making things difficult is a tricky business. If a game isn't difficult enough, experienced players lose interest. On the other hand, if it is too difficult, the initial enjoyment gives way to frustration. In fact, several psychological factors hang in a delicate balance: challenge, enjoyment, frustration, and curiosity. As the stu- dents reported, "Once the curiosity is...

    If we examine the history of advances in all technological fields, we see that some improvements naturally come through technology, others come through standardization. The early history of the automobile is a good example. The first cars were very difficult to operate. They required strength and skill beyond the abilities of many. Some problems were solved through automation: the choke, the spark...

    1. Use both knowledge in the world and knowledge in the head. 2. Simplify the structure of tasks. 3. Make things visible: bridge the gulfs of Execution and Evaluation. 4. Get the mappings right. 5. Exploit the power of constraints, both natural and artificial. 6. Design for error. 7. When all else fails, standardize

    • Put the required knowledge in the world. Don't require all the knowledge to be in the head. Yet do allow for more efficient opera- tion when the user has learned the operations, has gotten the knowl- edge in the head. • Use the power of natural and artificial constraints: physical, logical, semantic, and cultural. Use forcing functions and natural mappings. • Narrow the gulfs of execu...

    The same powers that make us so good at dealing with the common and the unique lead to severe error with the rare.

    That decision tree for chess is even wider and deeper—wide in the sense that at each point in the tree there are many alternatives, so that the tree spreads out over a considerable area; deep in the sense that most branches of the tree go on for a considerable distance. Everyday activities don't require the kind of complex analyses re- quired for something like chess. In most everyday activities...

    We can place slips into one of six categories: capture errors, description errors, data-driven errors, associative activation errors, loss-of-activation errors, and mode errors.
