Egosim
In all accounts it would seems as though Glaucon's argument supports that of psychological hedonism. He goes along with the fact that all humans behavior is motivated by obtaining pleasure or the avoidance of pain or consequence. People seek out their own personal interests above anything else. People who may do a "good" deed only do so because of the pleasure they derive from it not necessarily to help out the other person of for that of an act charity. It says that people only obey laws to avoid the consequence, however if they knew they could get away with breaking the law they would certainly do so.
Psychological egoism does not imply Ethical egoism. In fact they are two different things. Psychological egoism says that we DO always act selfishly and Ethical egoism says that we SHOULD act selfishly. Psychological egoism is the belief that people are only out for themselves all the time and just trying to be. Take for example an alcoholic, does this person drink and get drunk, act out, in pure self-interest or are they doing this selfishly, with no regards to others around them. He is doing what he wants, selfishly, but not in his self interests, this does not really benefit him to do so. Ethical egoism is more of a moral thing. We should we always do what we want regardless of how it will affect others or should we think about those consequences before acting. Ethically I would think twice about drinking cause while I may get pleasure out of the act and they high I am affecting others with my loud obnoxious behavior.
