For your final assignment you will  write an Abstract which is a single paragraph where you provide a brief overview of your proposal, including your hypothesis, major literature review findings, your study design (research method) and findings you think you will obtain. To that last point, you will also write up a Discussion section where you will speculate about the results you would get if you were to actually run this study and why you would anticipate these results. Also, you would comment on what these results would mean for the field of psychology and future research. As always, maintain appropriate APA format throughout your proposal. So, taking all together this would be the format of your final Research Proposal:
Title
Abstract
Literature Review / Introduction
Method Section
Discussion
