Herb s technique might work on Dagwood if he is able to change Dagwood s self-concept. You do not need to capitalize the names of theories or refer to them as, for example, the social comparison theory. If you are not sure whether the word the is appropriate, check your textbook to see how the concept is described or check with me if you are still unsure. Also, be sure that you call a theory by its full name. I have yet to see a paper that can explain everything thoroughly and carefully in less than a page and a half.
Most good papers are at least two full pages.
On the other hand, there is no reason to go over three pages.
