Recently, I have finished reading two books from the series “A Pocket Guide” by Five Simple Steps. One of them is “Psychology for Designers” by Joe Leech and the other one “The Craft of Words” by The Standartistas.
“Neuro Web Design” is a short book packed with knowledge and hints on the psychological side behind the click. It reads very easy and fast. I would say that it can be read within a 3-4 hour flight (including the time you take for the meal and going to the refreshment zone).
