Personas, Goals, and Emotional Design

When Don Norman's most recent book, Emotional Design, hit the shelves in early 2004, it sent a ripple through the user experience world. Norman introduced the idea that product design should address three different levels of cognitive and emotional processing: visceral, behavioral, and reflective. This idea seemed like old news to some and a revelation to others in the UX community. In either case, Norman's ideas, based on years of cognitive research, provide an articulated structure for modeling user responses to product and brand and a rational context for many intuitions long held by professional designers.
