Pro Tips for Choosing Your Topic

• Always anchor your topic sentence in a specific psychological theory (e.g., 'According to Self-Determination Theory...') to establish immediate academic authority.
• Avoid broad generalizations by specifying the population you are discussing, such as 'adolescents with ADHD' rather than just 'people'.
• Use transitional phrases that reflect psychological logic, such as 'In contrast to behavioral perspectives' or 'Building on the neurobiological evidence'.
• Ensure your topic sentence includes both the independent variable (the cause) and the dependent variable (the effect) to clarify your research focus.
• Check that your topic is narrow enough to be supported by peer-reviewed evidence within the word count of your assignment.
• Connect every topic sentence back to your central thesis to maintain a cohesive narrative flow throughout your paper.
