Research problems in Psychology
Your thesis in Psychology should ask and answer a specific question, rather than broadly discuss a large topic area. Furthermore, your research problem should suggest one or more subsequent questions to your readers.
The statement of the research problem should be precise and concise. It should be coherent enough that you can readily discuss it with family or friends - and that they will understand it.
It is recommended that you go over the four key parts (Research Question, Hypothesis, Evidence, Conclusions & Broader Implications) in an outline before you start to write your proposal.
