Edward teaches high school psychology.

Mr. Edward teaches high school psychology.  He has tried several times over the past few weeks to get the students in his psychology class to understand the differences between "negative reinforcement" and "punishment".  His students continue to confuse the two terms and he knows he must come up with a good example to help them to understand the meaning of the concepts. As an avid lover of music, Mr. Edward decided to apply his music tastes to the understanding of negative reinforcement and punishment.  He explains to his students that his own behavior that he is tiring to change relates  to doing laundry .  Mr. Edward share with his students that he procrastinate as long as he can  and he hates doing his laundry.  He also shares with his class his musical preferences.  Mr. Edwards love classic hard rock and dislikes country music. How could Mr. Edwards teach the concepts of negative reinforcement and punishment to explain how his music preferences could be used to change his behavior regarding doing laundry?
