Also, a book written by Vance Packard at the height of 1950s advertising called "The Hidden Persuaders", if you can find a copy. All about 'motivational research' and how subconscious cues can be used to sell and persuade. Very interesting -- for example, how some customers liked extremely-strong-smelling soap because it provided them with the same type of 'defense' in a socially-accepted way that B.O. did.
