This image is from the front of my textbook with a little bit about all the contributing professors to my psychology textbook.

The following are links to scanned chapters of my textbook that are written by Dr. Paul Vasey. Be forewarned that this is a frank discussion of monkeys and their mating habits, if you're not mature enough to handle it please don't read.
Keep in mind that this is recent, my version of the textbook being from 2005.
