Experiences at Missouri

One day my Social Psychology prof. got angry that students were leaving every day 10 -15 min before class was actually done(this was an hour and 15 min class), so he gave those of us who routinely stayed the whole class 5 answers free on the next exam. One whole letter grade, A+ anyone?

Exchange Theory is the science behind why people make the decisions that they do. It's very similar to making a list of pros and cons and then seeing which side wins. There is a whole passel of math involved in the actual theory, but despite that it really is quite interesting.
