“The dogs required to exert self-control 
(i.e., inhibit behavior) appeared to have 
depleted some important resource, which 
led to decreased persistence on the 
unsolvable task. By contrast, the dogs not 
required to exert self-control did not 
deplete this resource and persisted for a 
longer duration.”

“Content is king. Even though I was often 
testing sites to evaluate their interaction 
design, the test users were far more 
focused on the actual page content. Most 
users don’t go to the Web to “have an 
experience” or to enjoy the site designs: 
the UI is the barrier through which they 
reach for the content they want.”

function, and this is the law.

Editor's Notes

  • #4 In 1999, Professor Baba Shiv (currently at Stanford) and his co-author Alex Fedorikhin did a simple experiment on 165 undergrad students. They asked half to memorize a seven-digit number and the other half to memorize a two-digit number. After completing the memorization task, participants were told the experiment was over, and then offered a snack choice of either chocolate cake or a fruit bowl. The participants who memorized the seven-digit number were nearly 50% more likely than the other group to choose cake over fruit. Symbolic and real things
  • #6 Experiment 2 demonstrated that providing dogs with a boost of glucose eliminated the negative effects of prior exertion of self-control on persistence; this finding parallels a similar effect in humans.
  • #9 Do you agree? Why do we care about book cover? Book jacket design?
  • #13 Slider becomes “conventional”?
  • #19 Ask users about good design…
  • #22 Gestalt
  • #23 the top left and bottom right corners were significantly better recognized than the other 2 corners. Recognition performance was higher for banners centrally located. Shopping cart on the top right!
  • #25 an average person can hold temporarily in short-term memory. Card sorting Cited by 19917
  • #26 Picking links is not about short-term memory; More about labeling; Card sorting (in our case, mostly 4-6 groups)
  • #27 vertical symmetry should be considered an important factor in aesthetic website design. This study shows evidence that vertical symmetry has an impact on intuitive straightforward beauty appraisals and on classical and expressive aesthetics judgments made by the participants.
  • #44 Form follows function
  • #50 http://www.nytimes.com/2009/06/01/arts/01iht-DESIGN1.html?pagewanted=all&_r=0
