You may choose to investigate a specific theory, a specific line of research, or a specific topic.
Topics are pretty open and there are thousands of potential areas to discuss.
The attached articles are only examples of the types of journals and potential interesting subjects that are available. These are by no means inclusive of topics or articles. Journal articles or the texts can be modeled if you do not have access to a style manual. At least two of the sources consulted must be from a published journal article . The bibliographies at the end of the texts are decent guides to such literature.
