I just came in contact today with a new field of marketing, called Neuromarketing. In this field the reactions of the human brain on marketing methods is observed and marketers try to find out which method works best. It is quite interesting to see how people react to different marketing approaches and sometimes it is even totally absurd that people choose a product althought they definitely know that a different product is better or tastes better, but they just choose it because of marketing tricks.
Anyway I think I will go deeper into this sometime. If you want to read some interesting articles about Neuromarketing, here are two good sites:
The first one is in German: www.marktforschung-mit-neuromarketing.de
and the second one in English: neuromarketing.blogs.com
