Introduction:
Tell us about your topic. Why did you choose it? Why is it important to you? To psychologists? To the public at large?
What did other studies say about this? How do those studies relate to your idea?
Explain the methodology. Why were subjects chosen as they were? What are the positives of this method of sampling and the negatives?
Why did they choose the type of experiment they did (between vs within, etc). Or why is it a quasi experiment or single case research?
What are the limitations?
What about future research plans?
