What's between our wonderful web page and the user's brain ?
Two eyes sending to the brain :

- very quickly a large gray and fuzzy image
- slowly, an accurate and colored partial image.

Meanwhile the brain, impatient to hasten decision, seeks more information!
By dissecting understanding, emotion and decision of the user during first three seconds on an interface we rediscover and explain the "good practices" for interface designers in the User eXperience point of view.
