My behavioral problem is procrastination.

First, very briefly explain the behavioral problem. Then analyze the problem using theories, principles, and research findings learned in psychology. These are the concepts i applied from the McGraw-Hill textbook: Motivation, learning and memory, emotion, learning and behavior, and cognitive process. Apply them in a sufficiently substantial and detailed way to make it clear that you understand them well. That is define and explain the concepts and apply them to your problem in an explicit and detailed fashion as if you were explaining to someone who didn't take this class and isn't familiar with these psychological concepts.
