Pro Tips for Choosing Your Topic

• Always verify if your department uses Harvard (Author-Date) or a specific university variation, as punctuation in citations can differ.
• When citing classic theories (e.g., Freud or Piaget), try to include a 'cited in' reference if you are using a secondary source, or find the original translated text.
• Use the 'and' vs '&' rule correctly: use 'and' in the body of your text and '&' inside the parentheses for Harvard style.
• For papers involving neuroimaging, ensure you cite the specific software or atlas used (e.g., SPM or Talairach) as these are standard in psychology Harvard referencing.
• Focus your thesis on a 'mediating' or 'moderating' variable to move from a descriptive essay to a high-level analytical psychology paper.
